AI-generated art has revolutionized custom t-shirt design, but there's a catch: most AI platforms generate raster images (JPEG/PNG) that can look pixelated when printed. The secret to professional results? Converting to vector format (SVG).
Why Vector Graphics Are Essential for T-Shirt Printing
- ❌ Pixelate when enlarged
- ❌ Fixed resolution
- ❌ Large file sizes
- ❌ Quality loss when edited
- ❌ Not ideal for screen printing
- ✅ Infinite scalability
- ✅ Resolution independent
- ✅ Smaller file sizes
- ✅ Perfect for editing
- ✅ Ideal for all print methods

The 300 DPI Rule
T-shirt printing requires 300 DPI (dots per inch) at the final print size. While 72 DPI looks sharp on screens, it will appear pixelated when printed.
AI Image Limitations
- • Midjourney: Default 1024×1024px, upscaled max 2048×2048px
- • DALL-E 3: 1024×1024px or 1792×1024px
- • Stable Diffusion: Variable, typically 512-1024px
- • Adobe Firefly: Up to 2048×2048px
Formula: Pixels ÷ 300 DPI = Print Size (inches)

T-Shirt Printing Methods Comparison
Pros
- Most durable method
- Vibrant Pantone colors
- Cost-effective for bulk (under $5/shirt for 100+)
- Thick, professional ink layer
Cons
- High setup cost
- Each color needs separate screen
- Not ideal for photorealistic images
- Minimum order usually 20-50
Limited (1-12 spot colors)
Excellent (100+ washes)
$$$ setup ($15-50 per screen), $ per shirt
Yes
Color Separation for Screen Printing
Color separation is the process of breaking down a full-color image into individual color layers for screen printing. Each color needs its own screen, which is why this step is crucial for cost and quality.
Spot Color Separation
- • Uses Pantone (PMS) colors
- • Best for logos and simple graphics
- • Each color printed as solid ink
- • Most accurate color matching
- • Typical limit: 6-12 colors
Process Color Separation
- • CMYK or Simulated Process
- • Best for photorealistic images
- • Uses halftone dots
- • Can reproduce thousands of colors
- • Requires precise registration
Standard process printing
Better color accuracy
Limited palette method
Professional Tools
- • Separation Studio: $300 - Industry standard
- • UltraSeps: $900 - Advanced automation
- • AccuRIP: $495 - Film output specialist
Budget Options
- • Photoshop: Manual separation possible
- • GIMP: Free, requires expertise
- • QuikSeps: $99 - Entry level
File Preparation Checklist
Resolution Requirements
- Minimum 300 DPI for print
- Design area: typically 12" x 16" for adult shirts
- Upscale AI art before vectorizing for best results
Color Considerations
- Convert RGB to CMYK for accurate colors
- Limit to 6-8 colors for screen printing
- Use Pantone colors for brand consistency
File Formats
- SVG for vector graphics
- PDF for print-ready files
- AI/EPS for professional printers
Design Placement
- Leave 1" margin from seams
- Consider shirt size variations
- Test print on paper first
Pro Tips for Perfect Prints
Color Matching
Always request a physical color swatch or sample print before bulk orders
Layering
For complex designs, separate into layers for easier editing and color separation
File Organization
Name files clearly: "design-name_color-variant_size_date.svg"
Backup Everything
Keep original AI-generated files, converted SVGs, and final print files
