Addressed Problems

If a CMYK file is to be color managed for a destination CMYK digital proofer or printing press using ICC Device profiles, source CMYK data will be converted to CIELAB using the source ICC device profile, and then CIELAB colors are converted to destination CMYK values using the output ICC device profile. In this operation, important information about the source file contents can be lost.

For example, source pure C, M, Y or K color elements like text, color tints, vector graphics etc... are converted to 4 color CMYK on the output.

This can practically cause undesirable artifacts on the proof like grainy and dirty colors or misleading information like wrong dot structure.

On the printing press this CMYK->CIELAB->CMYK transformation may cause undesirable effects and even printability problems.

If black text or line art turns into CMYK, it will be very difficult to register, will have unsharp borders and will require more ink to print.
