When submitting image files for your Primoprint order, you will need to submit an 8-bit image to ensure the accuracy of your print job. 

8-bit vs. 16-bit

Primoprint uses a CMYK commercial printing process which is limited to printing 8-bit images only. The main difference between 8-bit and 16-bit images is the tonal variations available for each color. 16-bit images allow for much wider tonal variations per color. 8-bit allows for 256 tonal variations v. 16-bit with 65536 tonal variations per color.  

However, that large tonal range of a 16-bit image is not possible within the CMYK print process.  Within CMYK commercial printing you will have a more accurate representation of your image if you submit your files in 8-bit. 

Our Processing Team here at Primoprint reviews every file that is submitted, and will follow up with you directly if any changes need to be made to your files for any reason.
