Understanding the difference between vector and raster files for optimal print quality

Vector Files

Vector graphics use mathematical equations to create shapes and lines. They can be scaled infinitely without losing quality, making them ideal for printing.

  • Infinitely scalable without quality loss
  • Perfect for logos and text
  • Small file sizes
  • Formats: AI, EPS, SVG, PDF
  • Editable colors and shapes

Raster Files

Raster graphics are made of pixels. They're great for detailed images like photos but lose quality when scaled up beyond their original resolution.

  • Resolution-dependent quality
  • Best for photographs and complex images
  • Larger file sizes at high resolution
  • Formats: PNG, JPG, TIFF, PSD
  • Minimum 300 DPI for print quality

Best Practices for Print-Ready Files

  • Always provide vector files for logos, text, and simple graphics to ensure crisp printing at any size.
  • Use high-resolution raster images at minimum 300 DPI for photographic content to avoid pixelation.
  • Convert text to outlines in vector files to prevent font substitution issues during printing.
  • Use CMYK color mode for print files instead of RGB to ensure accurate color reproduction.
  • Include bleed area of at least 0.125 inches beyond the trim line for designs that extend to the edge.
  • Avoid thin lines below 0.5pt in vector files as they may not print clearly or could disappear entirely.
