Re: [tdf-discuss] PDF export in CMYK
Tibor thank you both for answers, I understand now the situation... My friend is historcian and he is not interested in learning any DTP technics – that is quite understandable. His first pdf exported from OO was flatly rejected as it was in RBG. It is fault or shortcoming of this publishing shop but he will not change it. Today, I found and tested pstill tool, it converts pdf to CMYK pdf, only colors (in included photos) are somehow shifted, or undersaturated. I had not investigated this issue yet, it might be something trivial … No not trivial, thats wath i mend with using correct colorspace, when the pictures in a LO doc are all the same colorspace, then tranforming to CMYK has a better change to produce better colors. This was some background, but I have following question: You wrote: „Important for this process is using the correct colorspace (sRGB or adobeRGB) is more important and there are we have no tools in LO !“ - are you trying to say, that OO/LibreOffice exports PDFs to wrong RGB type that can not be converted properly into CMYK pdf? If this would be the case it would be quite serious problem... I supose LO is not touching the colorspace precent in the original pictures, we slould have a tool (at least in draw) yo check the colorspace in a picture and to alter this all to the same space.

Re: [tdf-discuss] PDF export in CMYK
Hi, Most printshops do the RGB-CMYK conversion themselves, normal home/office printing devices take in RGB. If your friend wants to enter the field of real DTP (and does not have/want the cash to shell out to Adobe) he could go for Scribus, a cross-platform FOSS DTP application. Scribus imports styles and some formatting from OOo/LibO. The learning curve (in DTP) is quite steep, and you're entering a minefield of professional techniques and jargon which is best handled by the printshops - unless one wants to take the plunge themselves. The easiest would be to place the LibO-RGB.pdf in an image frame in Scribus (each page separately) and let Scribus render the file to Scribus-CMYK.pdf. There are also a bunch of command-line tools which can assist in such a conversion, but for them to be useful one has to know exactly which parameters to use.
