Artwork upload guidelines

High-quality artwork is the foundation of high-quality products. This guide explains how to prepare, size, and save your files so your prints look sharp, vibrant, and professional.

Recommended resolution

  • Aim for 300 DPI at the final print size whenever possible.
  • For large items (like blankets or posters), use the highest resolution you can reasonably work with.
  • Avoid stretching small images to fill large print areas – this can cause pixelation.

Print area & safe zone

Each product has a defined print area:

  • Keep all important elements (text, faces, logos) inside the safe zone shown in the designer.
  • Allow extra space around the edges for bleed and minor production shifts.
  • Avoid placing tiny text or details near seams, edges, or curved areas.

Color recommendations

  • Design in RGB (sRGB) color space for best compatibility with our systems.
  • Extremely bright neons, metallic effects, and glow effects may not print exactly as they appear on screen.
  • Always order a sample when color accuracy is critical.

For more on color, see Color accuracy and profiles.

File size and naming

  • Keep file sizes reasonable so they upload smoothly.
  • Use descriptive names (for example: cat_mom_mug_white_11oz_front.png).
  • Avoid special characters in file names (%, #, ?, etc.).

Content guidelines

You are responsible for the rights to any artwork you upload. Do not upload:

  • Copyrighted images you don't own or have permission to use.
  • Trademarked logos, characters, or slogans you don't own.
  • Content that is hateful, illegal, or violates our terms of service.

Quick checklist before uploading

  • ☐ 300 DPI at final print size
  • ☐ Important details inside safe zone
  • ☐ No low-resolution or blurry assets
  • ☐ File saved in a supported format (see Supported file formats)
  • ☐ You have the legal right to use the artwork
