![]() ![]() This is definitely no quality issue ('clipping', as you call it) but a necessity of the technical printing process (colors, paper, prining speed and much, much more. For example pushing up picture saturation or contrast will very fast end up in a ink coverage of 350 to 400%, what will be quite crucial for offset printing. But attention: If you convert an image into this profile and you continue editing the image (modifying contrast, exposure, brightness and so on), the result probably will no longer match the profile's goals and conditions. For example all online print companies in Germany strictly demand not to exceed 300% ink coverage and strongly recommend the use of ISO coated v2 300. If you convert a RGB image into CMYK using ISO coated v2 300, the profile guarantees, that ink coverage won't exceed 300%, what is very important for different printing processes. Especially the composition of 'black' differs widely in coated FORGRA and ISO coated. Because there are different ways to correctly reproduce a RGB color in CMYK color space, there are different ways to convert RGB colors into CMYK colors. There is a ISO standard for offset printing (ISO 12647-2) concerning optimal color space and reproduction in industrial printing. ![]()
