>> Hi all, Could anyone please advice me on what is the best way (or values) for converting a grayscale image to cmyk? The black in the grasycale image turns into too high values in the cmyk (C=91M=91Y=83K=99)...<<
Mattias, can you list the steps that you are taking, including the original GS value (100%K ??) and how/what you are converting into CMYK (the profile, rendering intent, BPC etc). What version of Photoshop??? NOT v5.x using RelCol I hope... Two things here... i) If you are going to run a four colour greyscale - then you need to know the grey balance so that you convert to the correct destination profile. ii) Using a much heavier GCR ratio than a normal profile such as the SWOP v2 from Adobe provides is MUCH better, as more black and less CMY makes the neutral easier to print. So, before going into all this in more detail it would be good to know what version you are using and how you are getting such high values for solid blacks...also cyan should be higher than the MY for a SWOP type grey balance, although in the solid deep shadows this is harder to notice than in lighter tones. Something does not sound correct. Then we can discuss your separation target and how to get a higher GCR ratio than what may be on offer in the prebuilt profile.
