ICC profiles and paper presets will enable you to maximise the print quality and accurately reproduces the original colours, by calibrating the printer settings prior to printing. Because each paper has a slightly different shade, surface structure and reacts differently, it is important that you use the setting that is specifically designed for this paper.
Once you have selected your printer brand and model, please tick the paper(s) and click on "Download". You get a zip file that contains ICC profile(s) and pdf guidelines to set up your printer. Please remember that other factors need to be configured to optimise the print results:
Check that your monitor is well calibrated
Check that you printer does not have any ink problems (blocked ink heads, lack of ink, etc..)
