Your graphics can be in .jpg, .tiff or .png format, in RGB method (we accept CMYK files, but colours will not be faithful) and with sRGBIEC profile 61966-2.1

It is best to have a file resolution above 150 dpi, with a maximum weight of 70Mb/90Mb. If you want a repeatable graphic, a full-size pattern must be created, which will then be repeated in the print preview.

n.b. Before saving the file in Photoshop or Illustrator, merge the layers and if saving in tiff format, choose LZW compression.
