------- Additional comments from [email protected] Mon Jun 21 09:44:23 +0000 2010 ------- As a stop-gap measure, would it be possible to change only the piece of code which translates RGB to-and-from CMYK? Obviously this is the major problem which causes the inconsistency. Even if OOo still stores the colour in RGB form, a more "accurate" conversion method would at least provide a more consistent CMYK value. It might still deviate slightly, but to such small effect that the difference wouldn't be discernible by eye. As for the "more-black-than-black" colours, this would only be possible using a different colour storage method. I even think only CMYK has this ability, which is actually defining a colour which "doesn't exist". The reason behind these colours are usually to force a printer to use all 4 its inks when creating black, usually to compensate for the black ink dye being a bit too gray. In this case we generally don't adjust for such in the documents. We adjust the printer's settings using colour correction methods. If you know the black comes out too washed out, the printer needs to be adjusted either mechanically (by using blacker ink) or through software (using colour correction in the driver). But then, that's because we own our own large format printers. When you have to rely on some outside printer service, you don't have this option. I would advise however, that you use some other type of program for pre-press ... maybe something like a DTP (search for Scribus)? --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
