Resolution, colour space and file formats

To achieve an optimal digital file for printing, you need to set up the resolution, colour space and file formats for each product.

Resolution

To get the optimal file resolution for a high quality print, please find for each product range you will find a professional section with the exact dimensions and resolutions for each product.

Colour Space

RGB

You can use image files in sRGB (sRGB IEC61966-2.1), Adobe RGB (1998) and ProPhoto RGB for photo prints. If you use image files in Adobe RGB (1998), please make sure that the profile has the right name Adobe RGB (1998). Only in this way can it be correctly recognised and processed.For multi-image products (collages) we recommend that the colour space of the files is identical.

The following colour spaces are not accepted:

  • Image files with embedded camera colour profiles
  • Image files in CMYK or ECI colour space
  • Special colours, such as HKS, RAL, Pantone cannot be produced

Greyscale

If a greyscale image in the RGB colour space does not have identical colour values, a colour cast can occur in the image. You must check that the RGB values are identical and adjust the image if necessary before ordering.
