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:

Plan all visual elements needed (title, intro, methods, results, conclusions)
Generate each element using scientific-schematics or Nano Banana Pro
Assemble generated images in the LaTeX template
Add text content around the visuals

Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.

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.

Required prompt additions for poster graphics:

POSTER FORMAT REQUIREMENTS:
- MAXIMUM 3-5 elements per graphic (NOT 10+)
- MAXIMUM 10-15 words total per graphic
- ALL text must be VERY LARGE and bold (readable from 6 feet away)
- Title text: minimum 72pt equivalent, bold
- Key metrics/numbers: minimum 60pt equivalent, bold  
- Labels and captions: minimum 36pt equivalent
- Use high contrast (dark text on light background or vice versa)
- GENEROUS white space (40-50% of graphic should be empty)
- Large icons and graphics with thick lines
- ONE main message per graphic

Content limits per graphic type:

Graphic Type	Max Elements	Max Words	Example
Flowchart	4-5 boxes	15 words	"DATA → PROCESS → MODEL → OUTPUT"
Key findings	3 items	12 words	"95% Accuracy, 2X Faster, Clinical Ready"
Comparison chart	3-4 bars	10 words	"Method A: 70%, Method B: 85%, Ours: 95%"
Diagram	3-5 components	15 words	Simple architecture with labeled parts

Example - WRONG (too much content, text too small):

# BAD - too complex, too many elements, no size specs
python scripts/generate_schematic.py "Infographic showing machine learning pipeline with data collection, preprocessing, feature extraction, model training, validation, hyperparameter tuning, testing, deployment, monitoring, and feedback loops. Include accuracy metrics, performance graphs, comparison tables, and technical specifications." -o figures/pipeline.png
# Result: Cluttered graphic with tiny unreadable text, overflow issues

Example - CORRECT (simple, poster-appropriate):

# GOOD - minimal content, explicit size requirements, generous spacing
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: DATA → MODEL → PREDICT → RESULT. Each box label in GIANT bold text (80pt+). Thick arrows between boxes. GENEROUS white space (50% empty). High contrast. Maximum 4 words per box. Readable from 8 feet." -o figures/pipeline.png
# Result: Clean, readable graphic with large text

Example - WRONG (key findings too complex):

# 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):

# 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

Step 1: Plan Your Poster Elements

Before creating the LaTeX poster, identify all visual elements needed:

Title Block - Stylized title with institutional branding (optional - can be LaTeX text)
Introduction Graphic - Conceptual overview or problem statement visual
Methods Diagram - Workflow, pipeline, or experimental design
Results Figures - Data visualizations, charts, key findings (2-4 figures)
Conclusion Graphic - Summary visual or take-home message
Supplementary Icons - Icons for sections, QR codes, logos

Step 2: Generate Each Element

Use the appropriate tool for each element type:

For Schematics and Diagrams (scientific-schematics):

# Create figures directory
mkdir -p figures

# Methods flowchart - SIMPLE, 4 steps only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: DATA → PROCESS → MODEL → RESULTS. Each label in GIANT bold text (80pt+). Thick arrows. 50% white space. NO additional details or sub-steps. Readable from 8 feet." -o figures/methods_flowchart.png

# System architecture - SIMPLE, 4 components only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE architecture diagram with ONLY 4 components: INPUT → NETWORK → PROCESSING → OUTPUT. GIANT labels (80pt+). Thick lines. 50% white space. NO layer details. Readable from 8 feet." -o figures/architecture.png

# Conceptual framework - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE diagram with ONLY 3 elements: A → B → C. Each label in GIANT bold text (80pt+). Thick arrows. 50% white space. NO additional text. Readable from 8 feet." -o figures/concept_framework.png

# Experimental design - SIMPLE, 3 groups only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE design diagram: CONTROL vs TREATMENT with arrow to OUTCOMES. ONLY 3 boxes total. GIANT labels (80pt+). 50% white space. NO detailed sub-groups. Readable from 8 feet." -o figures/experimental_design.png

For Stylized Blocks and Graphics (Nano Banana Pro):

# 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:

# 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 3: Assemble in LaTeX Template

Include all generated figures in your poster template:

tikzposter example:

\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:

\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

Remember: SIMPLE graphics with MINIMAL content. Each graphic = ONE message.

# 1. Create figures directory
mkdir -p figures

# 2. Generate SIMPLE visual elements - MAXIMUM 5 elements per graphic

# Problem statement - ONLY 3 icons
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with 3 icons only: PATIENT icon → DELAY icon → RISK icon. ONE word label each (80pt+). 50% white space. Readable from 8 feet." -o figures/problem.png

# Methods pipeline - ONLY 4 steps
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: IMAGES → PROCESS → MODEL → DIAGNOSIS. GIANT labels (100pt+). Thick arrows. 50% white space. NO sub-steps. Readable from 8 feet." -o figures/methods.png

# Architecture diagram - ONLY 4 components  
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE architecture with ONLY 4 blocks: INPUT → CNN → DENSE → OUTPUT. GIANT labels (80pt+). Thick lines. 50% white space. NO layer details. Readable from 8 feet." -o figures/architecture.png

# Results - ONLY 3 bars
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: 82% BASELINE, 88% EXISTING, 95% OURS (highlighted). GIANT percentages ON bars (120pt+). NO axis, NO legend. 40% white space. Readable from 10 feet." -o figures/results.png

# Key findings - ONLY 3 items with GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 cards only: '95%' (150pt) 'ACCURACY' (60pt), '2X' (150pt) 'FASTER' (60pt), checkmark 'VALIDATED' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions.png

# 3. Compile LaTeX poster with all figures
pdflatex poster.tex

If graphics still overflow or have small text:

Reduce number of elements further (try 3 instead of 5)
Add "EVEN SIMPLER" or "ONLY 3 elements" to prompt
Increase font size requirements (try 150pt+ for key numbers)
Add "60% white space" instead of 50%

Visual Element Guidelines

⚠️ CRITICAL: Each graphic should have ONE main message and MINIMAL content.

Content limits - NEVER exceed these:

Maximum 5 boxes/elements per flowchart
Maximum 3-4 bars per chart
Maximum 3 key findings per infographic
Maximum 15 words total per graphic
50% white space minimum

For each poster section, generate SIMPLE visuals with POSTER FORMAT:

Section	Max Elements	Example Prompt
Introduction	3-4 icons	"POSTER FORMAT for A0: SIMPLE problem visual with 3 large icons and 3 word labels. 50% white space."
Methods	4-5 boxes max	"POSTER FORMAT for A0: SIMPLE flowchart with ONLY 4 steps: A → B → C → D. GIANT labels (80pt+). 50% white space."
Results	3-4 bars max	"POSTER FORMAT for A0: SIMPLE bar chart with ONLY 3 bars. GIANT percentages (100pt+). NO legend, direct labels."
Conclusions	3 items only	"POSTER FORMAT for A0: ONLY 3 key findings. GIANT numbers (120pt+). One word labels. 50% white space."

MANDATORY prompt elements for poster graphics:

"POSTER FORMAT for A0" - size indicator
"SIMPLE" or "ONLY X elements" - content limit
"GIANT (80pt+)" or "HUGE (100pt+)" - font sizes
"50% white space" - prevent crowding
"readable from 6-8 feet" - viewing distance
Exact text that should appear (keep minimal!)

ANTI-PATTERNS TO AVOID:

❌ "Show all the steps in the methodology" → Too many elements
❌ "Include accuracy, precision, recall, F1, AUC" → Too many metrics
❌ "Comparison of 6 different methods" → Too many comparisons
❌ "Detailed architecture with all layers" → Too complex

CORRECT PATTERNS:

✅ "ONLY 4 main steps" → Limited elements
✅ "ONLY the top 3 metrics" → Focused content
✅ "Compare ONLY our method vs baseline" → Simple comparison
✅ "HIGH-LEVEL architecture with 4 components" → Simplified view

Ensuring Full Page Coverage:

Posters should use the entire page without excessive margins. Configure packages correctly:

beamerposter - Full Page Setup:

\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:

\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:

\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

% 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

% 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

% 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

# 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: 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 3: Reduced-Scale Print Test

Essential Pre-Printing Test:

# 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 4: Digital Quality Checks

Font Embedding Verification:

# 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:

# 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:

# 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 5: 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 6: 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 7: Technical Validation

LaTeX Compilation Log Review:

# 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:

% 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/}}

High contrast text and background
Clear visual hierarchy
Avoid complex textures or patterns in backgrounds

Language and Content:

Clear, concise language
Define acronyms and jargon
International audience considerations
Consider multilingual QR code options for global conferences

13. Poster Presentation Best Practices

Guidance beyond LaTeX for effective poster sessions:

Content Strategy:

Tell a story, don't just list facts
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

Determine poster requirements:
- Conference size specifications (A0, 36×48", etc.)
- Orientation (portrait vs. landscape)
- Submission deadlines and format requirements
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
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)

Create figures directory:
```
mkdir -p figures
```

Generate SIMPLE visual elements:

# 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

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

Select or create template:
- Start with provided templates in assets/
- Customize color scheme to match branding
- Configure page size and orientation
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%)
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

Create poster header:
- Title (concise, descriptive, 10-15 words)
- Authors and affiliations
- Institution logos (high-resolution)
- Conference logo if required
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
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
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

Review and iterate:
- Check for typos and errors
- Verify all figures are high resolution
- Ensure consistent formatting
- Confirm color scheme works well together
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
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

Compile final PDF:

pdflatex poster.tex
# Or for better font support:
lualatex poster.tex

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
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
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:

Add "SIMPLER" or "ONLY 3 elements" to prompt
Increase font sizes: "150pt+" instead of "80pt+"
Add "60% white space" instead of "50%"
Remove sub-details: "NO sub-steps", "NO axis labels", "NO legend"
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
