I'm laying out a children's book for print in InDesign. The print shop is in China and the rep made the unusual request of stripping the ICC profiles for all of the illustrations in the book. I had to make new CYMK files and choose Don't Color Manage for each. The problem I'm having is a pretty severe loss of saturation on one of the image files. I've attached a screenshot with the RGB original on the left and the CMYK untagged on the right. Look at the difference at the sky in both examples. Anything that had a hue of 296 in the rgb loses saturation and shifts hue towards pink, when moved to the untagged. I need to pump up the saturation for the 296 so I created a mask to isloate the sky and have tried the following: Applied a Hue Sat adjustment to the untagged file try to recover the saturation, but shifting the Sat slider all the way to +100 affects everything else but the sky. I tried converting the RGB original to Lab, applied Hue Sat with mask to boost sat without clipping it and then copy/paste to the untagged file - still loses saturation. Untagged - duplicated the layer, applied mask and tried changing the Blend to Color Burn. Dropped opacity to 50% and added a clipped Levels and shifted Black output to brighten the shadows introduced by Color Burn. This helped recover some saturation but it's still too weak. The screenshot you're seeing is a result of this step.
