# LaTeX Research Posters
## Overview
Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This skill provides comprehensive guidance for creating professional, visually appealing research posters using LaTeX packages. Generate publication-quality posters with proper layout, typography, color schemes, and visual hierarchy.
## When to Use This Skill
This skill should be used when:
- Creating research posters for conferences, symposia, or poster sessions
- Designing academic posters for university events or thesis defenses
- Preparing visual summaries of research for public engagement
- Converting scientific papers into poster format
- Creating template posters for research groups or departments
- Designing posters that comply with specific conference size requirements (A0, A1, 36×48", etc.)
- Building posters with complex multi-column layouts
- Integrating figures, tables, equations, and citations in poster format
## AI-Powered Visual Element Generation
**STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the LaTeX poster.**
This is the recommended approach for creating visually compelling posters:
1. Plan all visual elements needed (title, intro, methods, results, conclusions)
2. Generate each element using scientific-schematics or Nano Banana Pro
3. Assemble generated images in the LaTeX template
4. Add text content around the visuals
**Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.**
---
### CRITICAL: Preventing Content Overflow
**⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.**
**Common Overflow Problems:**
1. **Title/footer text extending beyond page boundaries**
2. **Too many sections crammed into available space**
3. **Figures placed too close to edges**
4. **Text blocks exceeding column widths**
**Prevention Rules:**
**1. Limit Content Sections (MAXIMUM 5-6 sections for A0):**
```
✅ GOOD - 5 sections with room to breathe:
- Title/Header
- Introduction/Problem
- Methods
- Results (1-2 key findings)
- Conclusions
❌ BAD - 8+ sections crammed together:
- Overview, Introduction, Background, Methods,
- Results 1, Results 2, Discussion, Conclusions, Future Work
```
**2. Set Safe Margins in LaTeX:**
```latex
% tikzposter - add generous margins
\documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}
% baposter - ensure content doesn't touch edges
\begin{poster}{
columns=3,
colspacing=2em, % Space between columns
headerheight=0.1\textheight, % Smaller header
% Leave space at bottom
}
```
**3. Figure Sizing - Never 100% Width:**
```latex
% Leave margins around figures
\includegraphics[width=0.85\linewidth]{figure.png} % NOT 1.0\linewidth
```
**4. Check for Overflow Before Printing:**
```bash
# Compile and check PDF at 100% zoom
pdflatex poster.tex
# Look for:
# - Text cut off at any edge
# - Content touching page boundaries
# - Overfull hbox warnings in .log file
grep -i "overfull" poster.log
```
**5. Word Count Limits:**
- **A0 poster**: 300-800 words MAXIMUM
- **Per section**: 50-100 words maximum
- **If you have more content**: Cut it or make a handout
---
### CRITICAL: Poster-Size Font Requirements
**⚠️ ALL text within AI-generated visualizations MUST be poster-readable.**
When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.
**⚠️ COMMON PROBLEM: Content Overflow and Density**
The #1 issue with AI-generated poster graphics is **TOO MUCH CONTENT**. This causes:
- Text overflow beyond boundaries
- Unreadable small fonts
- Cluttered, overwhelming visuals
- Poor white space usage
**SOLUTION: Generate SIMPLE graphics with MINIMAL content.**
**MANDATORY prompt requirements for EVERY poster graphic:**
```
POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)
```
**⚠️ BEFORE GENERATING: Review your prompt and count elements**
- If your description has 5+ items → STOP. Split into multiple graphics
- If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
- If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline
**Content limits per graphic type (STRICT):**
| Graphic Type | Max Elements | Max Words | Reject If | Good Example |
|--------------|--------------|-----------|-----------|--------------|
| Flowchart | **3-4 boxes MAX** | **8 words** | 5+ stages, nested steps | "DISCOVER → VALIDATE → APPROVE" (3 words) |
| Key findings | **3 items MAX** | **9 words** | 4+ metrics, paragraphs | "95% ACCURATE" "2X FASTER" "FDA READY" (6 words) |
| Comparison chart | **3 bars MAX** | **6 words** | 4+ methods, legend text | "OURS: 95%" "BEST: 85%" (4 words) |
| Case study | **1 case, 3 elements** | **6 words** | Multiple cases, substories | Logo + "18 MONTHS" + "to discovery" (2 words) |
| Timeline | **3-4 points MAX** | **8 words** | Year-by-year detail | "2020 START" "2022 TRIAL" "2024 APPROVED" (6 words) |
**Example - WRONG (7-stage workflow - TOO COMPLEX):**
```bash
# ❌ BAD - This creates tiny unreadable text like the drug discovery poster
python scripts/generate_schematic.py "Drug discovery workflow showing: Stage 1 Target Identification, Stage 2 Molecular Synthesis, Stage 3 Virtual Screening, Stage 4 AI Lead Optimization, Stage 5 Clinical Trial Design, Stage 6 FDA Approval. Include success metrics, timelines, and validation steps for each stage." -o figures/workflow.png
# Result: 7+ stages with tiny text, unreadable from 6 feet - POSTER FAILURE
```
**Example - CORRECT (simplified to 3 key stages):**
```bash
# ✅ GOOD - Same content, split into ONE simple high-level graphic
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. NO substeps, NO details. 3 words total. Readable from 10 feet." -o figures/workflow_overview.png
# Result: Clean, impactful, readable - can add detail graphics separately if needed
```
**Example - WRONG (complex case studies with multiple sections):**
```bash
# ❌ BAD - Creates cramped unreadable sections
python scripts/generate_schematic.py "Case studies: Insilico Medicine (drug candidate, discovery time, clinical trials), Recursion Pharma (platform, methodology, results), Exscientia (drug candidates, FDA status, timeline). Include company logos, metrics, and outcomes." -o figures/cases.png
# Result: 3 case studies with 4+ elements each = 12+ total elements, tiny text
```
**Example - CORRECT (one case study, one key metric):**
```bash
# ✅ GOOD - Show ONE case with ONE key number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study card: Company logo (large), '18 MONTHS' in GIANT text (150pt), 'to discovery' below (60pt). 3 elements total: logo + number + caption. 50% white space. Readable from 10 feet." -o figures/case_single.png
# Result: Clear, readable, impactful. Make 3 separate graphics if you need 3 cases.
```
**Example - WRONG (key findings too complex):**
```bash
# BAD - too many items, too much detail
python scripts/generate_schematic.py "Key findings showing 8 metrics: accuracy 95%, precision 92%, recall 94%, F1 0.93, AUC 0.97, training time 2.3 hours, inference 50ms, model size 145MB with comparison to 5 baseline methods" -o figures/findings.png
# Result: Cramped graphic with tiny numbers
```
**Example - CORRECT (key findings simple):**
```bash
# GOOD - only 3 key items, giant numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with ONLY 3 large cards. Card 1: '95%' in GIANT text (120pt) with 'ACCURACY' below (48pt). Card 2: '2X' in GIANT text with 'FASTER' below. Card 3: checkmark icon with 'VALIDATED' in large text. 50% white space. High contrast colors. NO other text or details." -o figures/findings.png
# Result: Bold, readable impact statement
```
**Font size reference for poster prompts:**
| Element | Minimum Size | Prompt Keywords |
|---------|--------------|-----------------|
| Main numbers/metrics | 72pt+ | "huge", "very large", "giant", "poster-size" |
| Section titles | 60pt+ | "large bold", "prominent" |
| Labels/captions | 36pt+ | "readable from 6 feet", "clear labels" |
| Body text | 24pt+ | "poster-readable", "large text" |
**Always include in prompts:**
- "POSTER FORMAT" or "for A0 poster" or "readable from 6 feet"
- "VERY LARGE TEXT" or "huge bold fonts"
- Specific text that should appear (so it's baked into the image)
- "minimal text, maximum impact"
- "high contrast" for readability
- "generous margins" and "no text near edges"
---
### CRITICAL: AI-Generated Graphic Sizing
**⚠️ Each AI-generated graphic should focus on ONE concept with MINIMAL content.**
**Problem**: Generating complex diagrams with many elements leads to small text.
**Solution**: Generate SIMPLE graphics with FEW elements and LARGE text.
**Example - WRONG (too complex, text will be small):**
```bash
# BAD - too many elements in one graphic
python scripts/generate_schematic.py "Complete ML pipeline showing data collection,
preprocessing with 5 steps, feature engineering with 8 techniques, model training
with hyperparameter tuning, validation with cross-validation, and deployment with
monitoring. Include all labels and descriptions." -o figures/pipeline.png
```
**Example - CORRECT (simple, focused, large text):**
```bash
# GOOD - split into multiple simple graphics with large text
# Graphic 1: High-level overview (3-4 elements max)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Simple 4-step pipeline.
Four large boxes: DATA → PROCESS → MODEL → RESULTS.
GIANT labels (80pt+), thick arrows, lots of white space.
Only 4 words total. Readable from 8 feet." -o figures/overview.png
# Graphic 2: Key result (1 metric highlighted)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Single key metric display.
Giant '95%' text (150pt+) with 'ACCURACY' below (60pt+).
Checkmark icon. Minimal design, high contrast.
Readable from 10 feet." -o figures/accuracy.png
```
**Rules for AI-generated poster graphics:**
| Rule | Limit | Reason |
|------|-------|--------|
| **Elements per graphic** | 3-5 maximum | More elements = smaller text |
| **Words per graphic** | 10-15 maximum | Minimal text = larger fonts |
| **Flowchart steps** | 4-5 maximum | Keeps labels readable |
| **Chart categories** | 3-4 maximum | Prevents crowding |
| **Nested levels** | 1-2 maximum | Avoids complexity |
**Split complex content into multiple simple graphics:**
```
Instead of 1 complex diagram with 12 elements:
→ Create 3 simple diagrams with 4 elements each
→ Each graphic can have LARGER text
→ Arrange in poster with clear visual flow
```
---
### Step 0: MANDATORY Pre-Generation Review (DO THIS FIRST)
**⚠️ BEFORE generating ANY graphics, review your content plan:**
**For EACH planned graphic, ask these questions:**
1. **Element count**: Can I describe this in 3-4 items or less?
- ❌ NO → Simplify or split into multiple graphics
- ✅ YES → Continue
2. **Complexity check**: Is this a multi-stage workflow (5+ steps) or nested diagram?
- ❌ YES → Flatten to 3-4 high-level steps only
- ✅ NO → Continue
3. **Word count**: Can I describe all text in 10 words or less?
- ❌ NO → Cut text, use single-word labels
- ✅ YES → Continue
4. **Message clarity**: Does this graphic convey ONE clear message?
- ❌ NO → Split into multiple focused graphics
- ✅ YES → Continue to generation
**Common patterns that ALWAYS fail (reject these):**
- "Show stages 1 through 7..." → Split into high-level overview (3 stages) + detail graphics
- "Multiple case studies..." → One case per graphic
- "Timeline from 2015 to 2024 with annual milestones..." → Show only 3-4 key years
- "Comparison of 6 methods..." → Show only top 3 or Our method vs Best baseline
- "Architecture with all layers and connections..." → High-level only (3-4 components)
### Step 1: Plan Your Poster Elements
After passing the pre-generation review, identify visual elements needed:
1. **Title Block** - Stylized title with institutional branding (optional - can be LaTeX text)
2. **Introduction Graphic** - Conceptual overview (3 elements max)
3. **Methods Diagram** - High-level workflow (3-4 steps max)
4. **Results Figures** - Key findings (3 metrics max per figure, may need 2-3 separate figures)
5. **Conclusion Graphic** - Summary visual (3 takeaways max)
6. **Supplementary Icons** - Simple icons, QR codes, logos (minimal)
### Step 2: Generate Each Element (After Pre-Generation Review)
**⚠️ CRITICAL: Review Step 0 checklist before proceeding.**
Use the appropriate tool for each element type:
**For Schematics and Diagrams (scientific-schematics):**
```bash
# Create figures directory
mkdir -p figures
# Drug discovery workflow - HIGH-LEVEL ONLY, 3 stages
# BAD: "Stage 1: Target ID, Stage 2: Molecular Synthesis, Stage 3: Virtual Screening, Stage 4: AI Lead Opt..."
# GOOD: Collapse to 3 mega-stages
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' (120pt bold) → 'VALIDATE' (120pt bold) → 'APPROVE' (120pt bold). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png
# System architecture - MAXIMUM 3 components
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-component stack: 'DATA' box (120pt) → 'AI MODEL' box (120pt) → 'PREDICTION' box (120pt). Thick vertical arrows. 60% white space. 3 words only. Readable from 12 feet." -o figures/architecture.png
# Timeline - ONLY 3 key milestones (not year-by-year)
# BAD: "2018, 2019, 2020, 2021, 2022, 2023, 2024 with events"
# GOOD: Only 3 breakthrough moments
python scripts/generate_schematic.py "POSTER FORMAT for A0. Timeline with ONLY 3 points: '2018' + icon, '2021' + icon, '2024' + icon. GIANT years (120pt). Large icons. 60% white space. NO connecting lines or details. Readable from 12 feet." -o figures/timeline.png
# Case study - ONE case, ONE key metric
# BAD: "3 case studies: Insilico (details), Recursion (details), Exscientia (details)"
# GOOD: ONE case with ONE number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study: Large logo + '18 MONTHS' (150pt bold) + 'to discovery' (60pt). 3 elements total. 60% white space. Readable from 12 feet." -o figures/case1.png
# If you need 3 cases → make 3 separate simple graphics (not one complex graphic)
```
**For Stylized Blocks and Graphics (Nano Banana Pro):**
```bash
# Title block - SIMPLE
python scripts/generate_schematic.py "POSTER FORMAT for A0. Title block: 'ML FOR DRUG DISCOVERY' in HUGE bold text (120pt+). Dark blue background. ONE subtle icon. NO other text. 40% white space. Readable from 15 feet." -o figures/title_block.png
# Introduction visual - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE problem visual with ONLY 3 icons: drug icon, arrow, target icon. ONE label per icon (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/intro_visual.png
# Conclusion/summary - ONLY 3 items, GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with EXACTLY 3 cards only. Card 1: '95%' (150pt font) with 'ACCURACY' (60pt). Card 2: '2X' (150pt) with 'FASTER' (60pt). Card 3: checkmark icon with 'READY' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions_graphic.png
# Background visual - SIMPLE, 3 icons only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 large icons in a row: problem icon → challenge icon → impact icon. ONE word label each (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/background_visual.png
```
**For Data Visualizations - SIMPLE, 3 bars max:**
```bash
# SIMPLE chart with ONLY 3 bars, GIANT labels
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentage labels ON the bars (100pt+). NO axis labels, NO legend, NO gridlines. Our bar highlighted in different color. 40% white space. Readable from 8 feet." -o figures/comparison_chart.png
```
### Step 2b: MANDATORY Post-Generation Review (Before Assembly)
**⚠️ CRITICAL: Review EVERY generated graphic before adding to poster.**
**For each generated figure, open at 25% zoom and check:**
1. **✅ PASS criteria (all must be true):**
- Can read ALL text clearly at 25% zoom
- Count elements: 3-4 or fewer
- White space: 50%+ of image is empty
- Simple enough to understand in 2 seconds
- NOT a complex workflow with 5+ stages
- NOT multiple nested sections
2. **❌ FAIL criteria (regenerate if ANY are true):**
- Text is small or hard to read at 25% zoom → REGENERATE with "150pt+" fonts
- More than 4 elements → REGENERATE with "ONLY 3 elements"
- Less than 50% white space → REGENERATE with "60% white space"
- Complex multi-stage workflow → SPLIT into 2-3 simple graphics
- Multiple case studies cramped together → SPLIT into separate graphics
- Takes more than 3 seconds to understand → SIMPLIFY and regenerate
**Common failures and fixes:**
- "7-stage workflow with tiny text" → Regenerate as "3 high-level stages only"
- "3 case studies in one graphic" → Generate 3 separate simple graphics
- "Timeline with 8 years" → Regenerate with "ONLY 3 key milestones"
- "Comparison of 5 methods" → Regenerate with "ONLY Our method vs Best baseline (2 bars)"
**DO NOT PROCEED to assembly if ANY graphic fails the checks above.**
### Step 3: Assemble in LaTeX Template
After all figures pass the post-generation review, include them in your poster template:
**tikzposter example:**
```latex
\documentclass[25pt, a0paper, portrait]{tikzposter}
\begin{document}
\maketitle
\begin{columns}
\column{0.5}
\block{Introduction}{
\centering
\includegraphics[width=0.85\linewidth]{figures/intro_visual.png}
\vspace{0.5em}
Brief context text here (2-3 sentences max).
}
\block{Methods}{
\centering
\includegraphics[width=0.9\linewidth]{figures/methods_flowchart.png}
}
\column{0.5}
\block{Results}{
\begin{minipage}{0.48\linewidth}
\centering
\includegraphics[width=\linewidth]{figures/result_1.png}
\end{minipage}
\hfill
\begin{minipage}{0.48\linewidth}
\centering
\includegraphics[width=\linewidth]{figures/result_2.png}
\end{minipage}
\vspace{0.5em}
Key findings in 3-4 bullet points.
}
\block{Conclusions}{
\centering
\includegraphics[width=0.8\linewidth]{figures/conclusions_graphic.png}
}
\end{columns}
\end{document}
```
**baposter example:**
```latex
\headerbox{Methods}{name=methods,column=0,row=0}{
\centering
\includegraphics[width=0.95\linewidth]{figures/methods_flowchart.png}
}
\headerbox{Results}{name=results,column=1,row=0}{
\includegraphics[width=\linewidth]{figures/comparison_chart.png}
\vspace{0.3em}
Key finding: Our method achieves 92% accuracy.
}
```
### Example: Complete Poster Generation Workflow
**Full workflow with ALL quality checks:**
```bash
# STEP 0: Pre-Generation Review (MANDATORY)
# Content plan: Drug discovery poster
# - Workflow: 7 stages → ❌ TOO MANY → Reduce to 3 mega-stages ✅
# - 3 case studies → ❌ TOO MANY → One case per graphic (make 3 graphics) ✅
# - Timeline 2018-2024 → ❌ TOO DETAILED → Only 3 key years ✅
# STEP 1: Create figures directory
mkdir -p figures
# STEP 2: Generate ULTRA-SIMPLE graphics with strict limits
# Workflow - HIGH-LEVEL ONLY (collapsed from 7 stages to 3)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word 120pt+ bold. Thick arrows (10px). 60% white space. ONLY 3 words total. Readable from 12 feet." -o figures/workflow.png
# Case study 1 - ONE case, ONE metric (will make 3 separate graphics)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '18 MONTHS' (150pt bold) + 'to drug discovery' (60pt). 3 elements only. 60% white space. Readable from 12 feet." -o figures/case1.png
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '95% SUCCESS' (150pt bold) + 'in trials' (60pt). 3 elements only. 60% white space." -o figures/case2.png
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + 'FDA APPROVED' (150pt bold) + '2024' (60pt). 3 elements only. 60% white space." -o figures/case3.png
# Timeline - ONLY 3 key years (not 7 years)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONLY 3 years: '2018' (150pt) + icon, '2021' (150pt) + icon, '2024' (150pt) + icon. Large icons. 60% white space. NO lines or details. Readable from 12 feet." -o figures/timeline.png
# Results - ONLY 2 bars (our method vs best baseline, not 5 methods)
python scripts/generate_schematic.py "POSTER FORMAT for A0. TWO bars only: 'BASELINE 70%' and 'OURS 95%' (highlighted). GIANT percentages (150pt) ON bars. NO axis, NO legend. 60% white space. Readable from 12 feet." -o figures/results.png
# STEP 2b: Post-Generation Review (MANDATORY)
# Open each figure at 25% zoom:
# ✅ workflow.png: 3 elements, text readable, 60% white - PASS
# ✅ case1.png: 3 elements, giant numbers, clean - PASS
# ✅ case2.png: 3 elements, giant numbers, clean - PASS
# ✅ case3.png: 3 elements, giant numbers, clean - PASS
# ✅ timeline.png: 3 elements, readable, simple - PASS
# ✅ results.png: 2 bars, giant percentages, clear - PASS
# ALL PASS → Proceed to assembly
# STEP 3: Compile LaTeX poster
pdflatex poster.tex
# STEP 4: PDF Overflow Check (see Section 11)
grep "Overfull" poster.log
# Open at 100% and check all 4 edges
```
**If ANY graphic fails Step 2b review:**
- Too many elements → Regenerate with "ONLY 3 elements"
- Small text → Regenerate with "150pt+" or "GIANT BOLD (150pt+)"
- Cluttered → Regenerate with "60% white space" and "ULTRA-SIMPLE"
- Complex workflow → SPLIT into multiple simple 3-element graphics
### Visual Element Guidelines
**⚠️ CRITICAL: Each graphic must have ONE message and MAXIMUM 3-4 elements.**
**ABSOLUTE LIMITS - These are NOT guidelines, these are HARD LIMITS:**
- **MAXIMUM 3-4 elements** per graphic (3 is ideal)
- **MAXIMUM 10 words** total per graphic
- **MINIMUM 50% white space** (60% is better)
- **MINIMUM 120pt** for key numbers/metrics
- **MINIMUM 80pt** for labels
**For each poster section - STRICT requirements:**
| Section | Max Elements | Max Words | Example Prompt (REQUIRED PATTERN) |
|---------|--------------|-----------|-------------------------------------|
| **Introduction** | 3 icons | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3 icons: [icon1] [icon2] [icon3]. ONE WORD labels (100pt bold). 60% white space. 3 words total." |
| **Methods** | 3 boxes | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3-box workflow: 'STEP1' → 'STEP2' → 'STEP3'. GIANT labels (120pt+). 60% white space. 3 words only." |
| **Results** | 2-3 bars | 6 words | "POSTER FORMAT for A0: TWO bars: 'BASELINE 70%' 'OURS 95%'. GIANT percentages (150pt+) ON bars. NO axis. 60% white space." |
| **Conclusions** | 3 cards | 9 words | "POSTER FORMAT for A0: THREE cards: '95%' (150pt) 'ACCURATE', '2X' (150pt) 'FASTER', checkmark 'READY'. 60% white space." |
| **Case Study** | 3 elements | 5 words | "POSTER FORMAT for A0: ONE case: logo + '18 MONTHS' (150pt) + 'to discovery' (60pt). 60% white space." |
| **Timeline** | 3 points | 3 words | "POSTER FORMAT for A0: THREE years only: '2018' '2021' '2024' (150pt each). Large icons. 60% white space. NO details." |
**MANDATORY prompt elements (ALL required, NO exceptions):**
1. **"POSTER FORMAT for A0"** - MUST be first
2. **"ULTRA-SIMPLE"** or **"ONLY X elements"** - content limit
3. **"GIANT (120pt+)"** or specific font sizes - readability
4. **"60% white space"** - mandatory breathing room
5. **"readable from 10-12 feet"** - viewing distance
6. **Exact count** of words/elements - "3 words total" or "ONLY 3 icons"
**PATTERNS THAT ALWAYS FAIL (REJECT IMMEDIATELY):**
- ❌ "7-stage drug discovery workflow" → Split to "3 mega-stages"
- ❌ "Timeline from 2015-2024 with annual updates" → "ONLY 3 key years"
- ❌ "3 case studies with details" → Make 3 separate simple graphics
- ❌ "Comparison of 5 methods with metrics" → "ONLY 2: ours vs best"
- ❌ "Complete architecture showing all layers" → "3 components only"
- ❌ "Show stages 1,2,3,4,5,6" → "3 high-level stages"
**PATTERNS THAT WORK:**
- ✅ "3 mega-stages collapsed from 7" → Proper simplification
- ✅ "ONE case with ONE metric" → Will make multiple if needed
- ✅ "ONLY 3 milestones" → Selective, focused
- ✅ "2 bars: ours vs baseline" → Direct comparison
- ✅ "3-component high-level view" → Appropriately simplified

### 2. Poster Layout and Structure
Create effective poster layouts following visual communication principles. For comprehensive layout guidance, refer to `references/poster_layout_design.md`.
**Common Poster Sections**:
- **Header/Title**: Title, authors, affiliations, logos
- **Introduction/Background**: Research context and motivation
- **Methods/Approach**: Methodology and experimental design
- **Results**: Key findings with figures and data visualizations
- **Conclusions**: Main takeaways and implications
- **References**: Key citations (typically abbreviated)
- **Acknowledgments**: Funding, collaborators, institutions
**Layout Strategies**:
- **Column-based layouts**: 2-column, 3-column, or 4-column grids
- **Block-based layouts**: Flexible arrangement of content blocks
- **Z-pattern flow**: Guide readers through content logically
- **Visual hierarchy**: Use size, color, and spacing to emphasize key points
### 3. Design Principles for Research Posters
Apply evidence-based design principles for maximum impact. For detailed design guidance, refer to `references/poster_design_principles.md`.
**Typography**:
- Title: 72-120pt for visibility from distance
- Section headers: 48-72pt
- Body text: 24-36pt minimum for readability from 4-6 feet
- Use sans-serif fonts (Arial, Helvetica, Calibri) for clarity
- Limit to 2-3 font families maximum
**Color and Contrast**:
- Use high-contrast color schemes for readability
- Institutional color palettes for branding
- Color-blind friendly palettes (avoid red-green combinations)
- White space is active space—don't overcrowd
**Visual Elements**:
- High-resolution figures (300 DPI minimum for print)
- Large, clear labels on all figures
- Consistent figure styling throughout
- Strategic use of icons and graphics
- Balance text with visual content (40-50% visual recommended)
**Content Guidelines**:
- **Less is more**: 300-800 words total recommended
- Bullet points over paragraphs for scannability
- Clear, concise messaging
- Self-explanatory figures with minimal text explanation
- QR codes for supplementary materials or online resources
### 4. Standard Poster Sizes
Support for international and conference-specific poster dimensions:
**International Standards**:
- A0 (841 × 1189 mm / 33.1 × 46.8 inches) - Most common European standard
- A1 (594 × 841 mm / 23.4 × 33.1 inches) - Smaller format
- A2 (420 × 594 mm / 16.5 × 23.4 inches) - Compact posters
**North American Standards**:
- 36 × 48 inches (914 × 1219 mm) - Common US conference size
- 42 × 56 inches (1067 × 1422 mm) - Large format
- 48 × 72 inches (1219 × 1829 mm) - Extra large
**Orientation**:
- Portrait (vertical) - Most common, traditional
- Landscape (horizontal) - Better for wide content, timelines
### 5. Package-Specific Templates

- Raster images: minimum 300 DPI at final print size
- Consistent image styling (borders, captions, sizes)
- Group related figures together
- Use subfigures for comparisons
**LaTeX Figure Commands**:
```latex
% Include graphics package
\usepackage{graphicx}
% Simple figure
\includegraphics[width=0.8\linewidth]{figure.pdf}
% Figure with caption in tikzposter
\block{Results}{
\begin{tikzfigure}
\includegraphics[width=0.9\linewidth]{results.png}
\end{tikzfigure}
}
% Multiple subfigures
\usepackage{subcaption}
\begin{figure}
\begin{subfigure}{0.48\linewidth}

```
**baposter**:
```latex
\begin{poster}{
background=plain,
bgColorOne=white,
headerColorOne=blue!70,
textborder=rounded
}
```
### 8. Typography and Text Formatting
Ensure readability and visual appeal:
**Font Selection**:
```latex
% Sans-serif fonts recommended for posters
\usepackage{helvet} % Helvetica
\usepackage{avant} % Avant Garde
\usepackage{sfmath} % Sans-serif math fonts
% Set default to sans-serif
\renewcommand{\familydefault}{\sfdefault}
```
**Text Sizing**:
```latex
% Adjust text sizes for visibility
\setbeamerfont{title}{size=\VeryHuge}
\setbeamerfont{author}{size=\Large}
\setbeamerfont{institute}{size=\normalsize}
```
**Emphasis and Highlighting**:
- Use bold for key terms: `\textbf{important}`
- Color highlights sparingly: `\textcolor{blue}{highlight}`
- Boxes for critical information
- Avoid italics (harder to read from distance)
### 9. QR Codes and Interactive Elements
Enhance poster interactivity for modern conferences:
**QR Code Integration**:

### 10. Compilation and Output
Generate high-quality PDF output for printing or digital display:
**Compilation Commands**:
```bash
# Basic compilation
pdflatex poster.tex
# With bibliography
pdflatex poster.tex
bibtex poster
pdflatex poster.tex
pdflatex poster.tex
# For beamer-based posters
lualatex poster.tex # Better font support
xelatex poster.tex # Unicode and modern fonts
```
**Ensuring Full Page Coverage**:
Posters should use the entire page without excessive margins. Configure packages correctly:
**beamerposter - Full Page Setup**:
```latex
\documentclass[final,t]{beamer}
\usepackage[size=a0,scale=1.4,orientation=portrait]{beamerposter}
% Remove default beamer margins
\setbeamersize{text margin left=0mm, text margin right=0mm}
% Use geometry for precise control
\usepackage[margin=10mm]{geometry} % 10mm margins all around
% Remove navigation symbols
\setbeamertemplate{navigation symbols}{}
% Remove footline and headline if not needed
\setbeamertemplate{footline}{}
\setbeamertemplate{headline}{}
```
**tikzposter - Full Page Setup**:
```latex
\documentclass[
25pt, % Font scaling
a0paper, % Paper size
portrait, % Orientation
margin=10mm, % Outer margins (minimal)
innermargin=15mm, % Space inside blocks
blockverticalspace=15mm, % Space between blocks
colspace=15mm, % Space between columns
subcolspace=8mm % Space between subcolumns
]{tikzposter}
% This ensures content fills the page
```
**baposter - Full Page Setup**:
```latex
\documentclass[a0paper,portrait,fontscale=0.285]{baposter}
\begin{poster}{
grid=false,
columns=3,
colspacing=1.5em, % Space between columns
eyecatcher=true,
background=plain,
bgColorOne=white,
borderColor=blue!50,
headerheight=0.12\textheight, % 12% for header
textborder=roundedleft,
headerborder=closed,
boxheaderheight=2em % Consistent box header heights
}
% Content here
\end{poster}
```
**Common Issues and Fixes**:
**Problem**: Large white margins around poster
```latex
% Fix for beamerposter
\setbeamersize{text margin left=5mm, text margin right=5mm}
% Fix for tikzposter
\documentclass[..., margin=5mm, innermargin=10mm]{tikzposter}
% Fix for baposter - adjust in document class
\documentclass[a0paper, margin=5mm]{baposter}
```
**Problem**: Content doesn't fill vertical space
```latex
% Use \vfill between sections to distribute space
\block{Introduction}{...}
\vfill
\block{Methods}{...}
\vfill
\block{Results}{...}
% Or manually adjust block spacing
\vspace{1cm} % Add space between specific blocks
```
**Problem**: Poster extends beyond page boundaries
```latex
% Check total width calculation
% For 3 columns with spacing:
% Total = 3×columnwidth + 2×colspace + 2×margins
% Ensure this equals \paperwidth
% Debug by adding visible page boundary
\usepackage{eso-pic}
\AddToShipoutPictureBG{
\AtPageLowerLeft{
\put(0,0){\framebox(\LenToUnit{\paperwidth},\LenToUnit{\paperheight}){}}
}
}
```
**Print Preparation**:
- Generate PDF/X-1a for professional printing
- Embed all fonts
- Convert colors to CMYK if required
- Check resolution of all images (minimum 300 DPI)
- Add bleed area if required by printer (usually 3-5mm)
- Verify page size matches requirements exactly
**Digital Display**:
- RGB color space for screen display
- Optimize file size for email/web
- Test readability on different screens
### 11. PDF Review and Quality Control
**CRITICAL**: Always review the generated PDF before printing or presenting. Use this systematic checklist:
**Step 1: Page Size Verification**
```bash
# Check PDF dimensions (should match poster size exactly)
pdfinfo poster.pdf | grep "Page size"
# Expected outputs:
# A0: 2384 x 3370 points (841 x 1189 mm)
# 36x48": 2592 x 3456 points
# A1: 1684 x 2384 points (594 x 841 mm)
```
**Step 2: OVERFLOW CHECK (CRITICAL) - DO THIS IMMEDIATELY AFTER COMPILATION**
**⚠️ THIS IS THE #1 CAUSE OF POSTER FAILURES. Check BEFORE proceeding.**
**Step 2a: Check LaTeX Log File**
```bash
# Check for overflow warnings (these are ERRORS, not suggestions)
grep -i "overfull\|underfull\|badbox" poster.log
# ANY "Overfull" warning = content is cut off or extending beyond boundaries
# FIX ALL OF THESE before proceeding
```
**Common overflow warnings and what they mean:**
- `Overfull \hbox (15.2pt too wide)` → Text or graphic is 15.2pt wider than column
- `Overfull \vbox (23.5pt too high)` → Content is 23.5pt taller than available space
- `Badbox` → LaTeX struggling to fit content within boundaries
**Step 2b: Visual Edge Inspection (100% zoom in PDF viewer)**
**Check ALL FOUR EDGES systematically:**
1. **TOP EDGE:**
- [ ] Title completely visible (not cut off)
- [ ] Author names fully visible
- [ ] No graphics touching top margin
- [ ] Header content within safe zone
2. **BOTTOM EDGE:**
- [ ] References fully visible (not cut off)
- [ ] Acknowledgments complete
- [ ] Contact info readable
- [ ] No graphics cut off at bottom
3. **LEFT EDGE:**
- [ ] No text touching left margin
- [ ] All bullet points fully visible
- [ ] Graphics have left margin (not bleeding off)
- [ ] Column content within bounds
4. **RIGHT EDGE:**
- [ ] No text extending beyond right margin
- [ ] Graphics not cut off on right
- [ ] Column content stays within bounds
- [ ] QR codes fully visible
5. **BETWEEN COLUMNS:**
- [ ] Content stays within individual columns
- [ ] No text bleeding into adjacent columns
- [ ] Figures respect column boundaries
**If ANY check fails, you have overflow. FIX IMMEDIATELY before continuing:**
**Fix hierarchy (try in order):**
1. **Check AI-generated graphics first:**
- Are they too complex (5+ elements)? → Regenerate simpler
- Do they have tiny text? → Regenerate with "150pt+" fonts
- Are there too many? → Reduce number of figures
2. **Reduce sections:**
- More than 5-6 sections? → Combine or remove
- Example: Merge "Discussion" into "Conclusions"
3. **Cut text content:**
- More than 800 words total? → Cut to 300-500
- More than 100 words per section? → Cut to 50-80
4. **Adjust figure sizing:**
- Using `width=\linewidth`? → Change to `width=0.85\linewidth`
- Using `width=1.0\columnwidth`? → Change to `width=0.9\columnwidth`
5. **Increase margins (last resort):**
```latex
\documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}
```
**DO NOT proceed to Step 3 if ANY overflow exists.**
**Step 3: Visual Inspection Checklist**
Open PDF at 100% zoom and check:
**Layout and Spacing**:
- [ ] Content fills entire page (no large white margins)
- [ ] Consistent spacing between columns
- [ ] Consistent spacing between blocks/sections
- [ ] All elements aligned properly (use ruler tool)
- [ ] No overlapping text or figures
- [ ] White space evenly distributed
**Typography**:
- [ ] Title clearly visible and large (72pt+)
- [ ] Section headers readable (48-72pt)
- [ ] Body text readable at 100% zoom (24-36pt minimum)
- [ ] No text cutoff or running off edges
- [ ] Consistent font usage throughout
- [ ] All special characters render correctly (symbols, Greek letters)
**Visual Elements**:
- [ ] All figures display correctly
- [ ] No pixelated or blurry images
- [ ] Figure captions present and readable
- [ ] Colors render as expected (not washed out or too dark)
- [ ] Logos display clearly
- [ ] QR codes visible and scannable
**Content Completeness**:
- [ ] Title and authors complete
- [ ] All sections present (Intro, Methods, Results, Conclusions)
- [ ] References included
- [ ] Contact information visible
- [ ] Acknowledgments (if applicable)
- [ ] No placeholder text remaining (Lorem ipsum, TODO, etc.)
**Technical Quality**:
- [ ] No LaTeX compilation warnings in important areas
- [ ] All citations resolved (no [?] marks)
- [ ] All cross-references working
- [ ] Page boundaries correct (no content cut off)
**Step 4: Reduced-Scale Print Test**
**Essential Pre-Printing Test**:
```bash
# Create reduced-size test print (25% of final size)
# This simulates viewing full poster from ~8-10 feet
# For A0 poster, print on A4 paper (24.7% scale)
# For 36x48" poster, print on letter paper (~25% scale)
```
**Print Test Checklist**:
- [ ] Title readable from 6 feet away
- [ ] Section headers readable from 4 feet away
- [ ] Body text readable from 2 feet away
- [ ] Figures clear and understandable
- [ ] Colors printed accurately
- [ ] No obvious design flaws
**Step 5: Digital Quality Checks**
**Font Embedding Verification**:
```bash
# Check that all fonts are embedded (required for printing)
pdffonts poster.pdf
# All fonts should show "yes" in "emb" column
# If any show "no", recompile with:
pdflatex -dEmbedAllFonts=true poster.tex
```
**Image Resolution Check**:
```bash
# Extract image information
pdfimages -list poster.pdf
# Check that all images are at least 300 DPI
# Formula: DPI = pixels / (inches in poster)
# For A0 width (33.1"): 300 DPI = 9930 pixels minimum
```
**File Size Optimization**:
```bash
# For email/web, compress if needed (>50MB)
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
-dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH \
-sOutputFile=poster_compressed.pdf poster.pdf
# For printing, keep original (no compression)
```
**Step 6: Accessibility Check**
**Color Contrast Verification**:
- [ ] Text-background contrast ratio ≥ 4.5:1 (WCAG AA)
- [ ] Important elements contrast ratio ≥ 7:1 (WCAG AAA)
- Test online: https://webaim.org/resources/contrastchecker/
**Color Blindness Simulation**:
- [ ] View PDF through color blindness simulator
- [ ] Information not lost with red-green simulation
- [ ] Use Coblis (color-blindness.com) or similar tool
**Step 7: Content Proofreading**
**Systematic Review**:
- [ ] Spell-check all text
- [ ] Verify all author names and affiliations
- [ ] Check all numbers and statistics for accuracy
- [ ] Confirm all citations are correct
- [ ] Review figure labels and captions
- [ ] Check for typos in headers and titles
**Peer Review**:
- [ ] Ask colleague to review poster
- [ ] 30-second test: Can they identify main message?
- [ ] 5-minute review: Do they understand conclusions?
- [ ] Note any confusing elements
**Step 8: Technical Validation**
**LaTeX Compilation Log Review**:
```bash
# Check for warnings in .log file
grep -i "warning\|error\|overfull\|underfull" poster.log
# Common issues to fix:
# - Overfull hbox: Text extending beyond margins
# - Underfull hbox: Excessive spacing
# - Missing references: Citations not resolved
# - Missing figures: Image files not found
```
**Fix Common Warnings**:
```latex
% Overfull hbox (text too wide)
\usepackage{microtype} % Better spacing
\sloppy % Allow slightly looser spacing
\hyphenation{long-word} % Manual hyphenation
% Missing fonts
\usepackage[T1]{fontenc} % Better font encoding
% Image not found
% Ensure paths are correct and files exist
\graphicspath{{./figures/}{./images/}}
```
**Step 9: Final Pre-Print Checklist**
**Before Sending to Printer**:
- [ ] PDF size exactly matches requirements (check with pdfinfo)
- [ ] All fonts embedded (check with pdffonts)
- [ ] Color mode correct (RGB for screen, CMYK for print if required)

- Focus on 1-3 main messages
- Use visual abstract or graphical summary
- Leave room for conversation (don't over-explain)
**Physical Presentation Tips**:
- Bring printed handouts or business cards with QR code
- Prepare 30-second, 2-minute, and 5-minute verbal summaries
- Stand to the side, not blocking the poster
- Engage viewers with open-ended questions
**Digital Backups**:
- Save poster as PDF on mobile device
- Prepare digital version for email sharing
- Create social media-friendly image version
- Have backup printed copy or digital display option
## Workflow for Poster Creation
### Stage 1: Planning and Content Development
1. **Determine poster requirements**:
- Conference size specifications (A0, 36×48", etc.)
- Orientation (portrait vs. landscape)
- Submission deadlines and format requirements
2. **Develop content outline**:
- Identify 1-3 core messages
- Select key figures (typically 3-6 main visuals)
- Draft concise text for each section (bullet points preferred)
- Aim for 300-800 words total
3. **Choose LaTeX package**:
- beamerposter: If familiar with Beamer, need institutional themes
- tikzposter: For modern, colorful designs with flexibility
- baposter: For structured, professional multi-column layouts
### Stage 2: Generate Visual Elements (AI-Powered)
**CRITICAL: Generate SIMPLE figures with MINIMAL content. Each graphic = ONE message.**
**Content limits:**
- Maximum 4-5 elements per graphic
- Maximum 15 words total per graphic
- 50% white space minimum
- GIANT fonts (80pt+ for labels, 120pt+ for key numbers)
1. **Create figures directory**:
```bash
mkdir -p figures
```
2. **Generate SIMPLE visual elements**:
```bash
# Introduction - ONLY 3 icons/elements
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 elements: [icon1] [icon2] [icon3]. ONE word labels (80pt+). 50% white space. Readable from 8 feet." -o figures/intro.png
# Methods - ONLY 4 steps maximum
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: STEP1 → STEP2 → STEP3 → STEP4. GIANT labels (100pt+). 50% white space. NO sub-steps." -o figures/methods.png
# Results - ONLY 3 bars/comparisons
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE chart with ONLY 3 bars. GIANT percentages ON bars (120pt+). NO axis, NO legend. 50% white space." -o figures/results.png
# Conclusions - EXACTLY 3 items with GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 key findings: '[NUMBER]' (150pt) '[LABEL]' (60pt) for each. 50% white space. NO other text." -o figures/conclusions.png
```
3. **Review generated figures - check for overflow:**
- **View at 25% zoom**: All text still readable?
- **Count elements**: More than 5? → Regenerate simpler
- **Check white space**: Less than 40%? → Add "60% white space" to prompt
- **Font too small?**: Add "EVEN LARGER" or increase pt sizes
- **Still overflowing?**: Reduce to 3 elements instead of 4-5
### Stage 3: Design and Layout
1. **Select or create template**:
- Start with provided templates in `assets/`
- Customize color scheme to match branding
- Configure page size and orientation
2. **Design layout structure**:
- Plan column structure (2, 3, or 4 columns)
- Map content flow (typically left-to-right, top-to-bottom)
- Allocate space for title (10-15%), content (70-80%), footer (5-10%)
3. **Set typography**:
- Configure font sizes for different hierarchy levels
- Ensure minimum 24pt body text
- Test readability from 4-6 feet distance
### Stage 4: Content Integration
1. **Create poster header**:
- Title (concise, descriptive, 10-15 words)
- Authors and affiliations
- Institution logos (high-resolution)
- Conference logo if required
2. **Integrate AI-generated figures**:
- Add all figures from Stage 2 to appropriate sections
- Use `\includegraphics` with proper sizing
- Ensure figures dominate each section (visuals first, text second)
- Center figures within blocks for visual impact
3. **Add minimal supporting text**:
- Keep text minimal and scannable (300-800 words total)
- Use bullet points, not paragraphs
- Write in active voice
- Text should complement figures, not duplicate them
4. **Add supplementary elements**:
- QR codes for supplementary materials
- References (cite key papers only, 5-10 typical)
- Contact information and acknowledgments
### Stage 5: Refinement and Testing
1. **Review and iterate**:
- Check for typos and errors
- Verify all figures are high resolution
- Ensure consistent formatting
- Confirm color scheme works well together
2. **Test readability**:
- Print at 25% scale and read from 2-3 feet (simulates poster from 8-12 feet)
- Check color on different monitors
- Verify QR codes function correctly
- Ask colleague to review
3. **Optimize for printing**:
- Embed all fonts in PDF
- Verify image resolution
- Check PDF size requirements
- Include bleed area if required
### Stage 6: Compilation and Delivery
1. **Compile final PDF**:
```bash
pdflatex poster.tex
# Or for better font support:
lualatex poster.tex
```
2. **Verify output quality**:
- Check all elements are visible and correctly positioned
- Zoom to 100% and inspect figure quality
- Verify colors match expectations
- Confirm PDF opens correctly on different viewers
3. **Prepare for printing**:
- Export as PDF/X-1a if required
- Save backup copies
- Get test print on regular paper first
- Order professional printing 2-3 days before deadline
4. **Create supplementary materials**:
- Save PNG/JPG version for social media
- Create handout version (8.5×11" summary)
- Prepare digital version for email sharing
## Integration with Other Skills
This skill works effectively with:
- **Scientific Schematics**: CRITICAL - Use for generating all poster diagrams and flowcharts
- **Generate Image / Nano Banana Pro**: For stylized graphics, conceptual illustrations, and summary visuals
- **Scientific Writing**: For developing poster content from papers
- **Literature Review**: For contextualizing research
- **Data Analysis**: For creating result figures and charts
**Recommended workflow**: Always use scientific-schematics and generate-image skills BEFORE creating the LaTeX poster to generate all visual elements.
## Common Pitfalls to Avoid
**AI-Generated Graphics Mistakes (MOST COMMON):**
- ❌ Too many elements in one graphic (10+ items) → Keep to 3-5 max
- ❌ Text too small in AI graphics → Specify "GIANT (100pt+)" or "HUGE (150pt+)"
- ❌ Too much detail in prompts → Use "SIMPLE" and "ONLY X elements"
- ❌ No white space specification → Add "50% white space" to every prompt
- ❌ Complex flowcharts with 8+ steps → Limit to 4-5 steps maximum
- ❌ Comparison charts with 6+ items → Limit to 3 items maximum
- ❌ Key findings with 5+ metrics → Show only top 3
**Fixing Overflow in AI Graphics:**
If your AI-generated graphics are overflowing or have small text:
1. Add "SIMPLER" or "ONLY 3 elements" to prompt
2. Increase font sizes: "150pt+" instead of "80pt+"
3. Add "60% white space" instead of "50%"
4. Remove sub-details: "NO sub-steps", "NO axis labels", "NO legend"
5. Regenerate with fewer elements
**Design Mistakes**:
- ❌ Too much text (over 1000 words)
- ❌ Font sizes too small (under 24pt body text)
- ❌ Low-contrast color combinations
- ❌ Cluttered layout with no white space
- ❌ Inconsistent styling across sections
- ❌ Poor quality or pixelated images
**Content Mistakes**:
- ❌ No clear narrative or message
- ❌ Too many research questions or objectives
- ❌ Overuse of jargon without definitions
- ❌ Results without context or interpretation
- ❌ Missing author contact information
**Technical Mistakes**:
- ❌ Wrong poster dimensions for conference requirements
- ❌ RGB colors sent to CMYK printer (color shift)
- ❌ Fonts not embedded in PDF
- ❌ File size too large for submission portal
- ❌ QR codes too small or not tested
**Best Practices**:
- ✅ Generate SIMPLE AI graphics with 3-5 elements max
- ✅ Use GIANT fonts (100pt+) for key numbers in graphics
- ✅ Specify "50% white space" in every AI prompt
- ✅ Follow conference size specifications exactly
- ✅ Test print at reduced scale before final printing
- ✅ Use high-contrast, accessible color schemes
- ✅ Keep text minimal and highly scannable
- ✅ Include clear contact information and QR codes
- ✅ Proofread carefully (errors are magnified on posters!)
## Package Installation
Ensure required LaTeX packages are installed:
```bash
# For TeX Live (Linux/Mac)
tlmgr install beamerposter tikzposter baposter
# For MiKTeX (Windows)
# Packages typically auto-install on first use
# Additional recommended packages
tlmgr install qrcode graphics xcolor tcolorbox subcaption
```
