Requirements to print your image:

  • File format: PNG format is recommended for optimum quality. Most other formats do not recognize transparent zones and automatically add a white background to the image.
  • Size limit: max. 10 MB
  • Resolution: at least 1000 pixels on the shorter side, max 4000 pixels on the longer side

Transparent background

Pixel graphics are used as the master copy for Digital Direct printing. These graphics are printed on the shirt exactly as they were uploaded. If your graphic contains a background, this will also be printed as it appears.

A common desire is to print a cropped element of an image without the background. A white background is not sufficient here as printing the design – even on white products – would result in printing the white area as well. This is why the background needs to be transparent so that our printers will ignore it.

 If you do not want the background to be printed on the shirt, you must crop your design (meaning to cut your design from the background). By doing this, you make your design’s background transparent.

Most graphics editing software programs show transparent backgrounds as a white-gray checkerboard pattern. If you upload a graphic with a transparent background, the color of the shirt will appear in those areas after the printing is finished.
