LaTeX Research Posters

Overview

When to Use This Skill

• 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

Visual Enhancement with Scientific Schematics

1. Generate at minimum TWO schematics or diagrams
2. Target 3-4 figures for comprehensive posters (methodology flowchart, key results visualization, conceptual framework)
3. Figures should occupy 40-50% of poster area

• Use the scientific-schematics skill to generate AI-powered publication-quality diagrams
• Simply describe your desired diagram in natural language
• Nano Banana Pro will automatically generate, review, and refine the schematic

python scripts/generate_schematic.py "your diagram description" -o figures/output.png

• Create publication-quality images with proper formatting
• Review and refine through multiple iterations
• Ensure accessibility (colorblind-friendly, high contrast)
• Save outputs in the figures/ directory

• Research methodology flowcharts for poster content
• Conceptual framework diagrams
• Experimental design visualizations
• Data analysis pipeline diagrams
• System architecture diagrams
• Biological pathway illustrations
• Any complex concept that benefits from visualization

• Strategic use of icons and graphics
• Balance text with visual content (40-50% visual recommended)

• 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

• 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

• 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

• Portrait (vertical) - Most common, traditional
• Landscape (horizontal) - Better for wide content, timelines

   • 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: 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 3: Content Integration

1. Create poster header:
   • Title (concise, descriptive, 10-15 words)
   • Authors and affiliations
   • Institution logos (high-resolution)
   • Conference logo if required
2. Populate content sections:
   • Keep text minimal and scannable
   • Use bullet points, not paragraphs
   • Write in active voice
   • Integrate figures with clear captions
3. Add visual elements:
   • High-resolution figures (300 DPI minimum)
   • Consistent styling across all figures
   • Color-coded elements for emphasis
   • QR codes for supplementary materials
4. Include references:
   • Cite key papers only (5-10 references typical)
   • Use abbreviated citation style
   • Consider QR code to full bibliography

Stage 4: 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 5: 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
