Thanks a lot to all of you. First of all, I have to say that I agree with Benjamin Root.
I'll try the tools some of you suggested (no problem in installing and trying, as soon as I can ... but it's good to know that there is a way to generate CMYK images using Python ... as I told it will be useful to have these suggestions recorded on the Matplotlib web site). If amongst the readers of this mailing list there are also some Matplotlib developers, I'd like to say them that to have the CMYK option incorporated into Matplotlib (for example like it is incorporated into the MATLAB print command) will be a great improvement. I started using Python only because I wanted to stop using MATLAB. I've found Python a lot more powerful than MATLAB on nearly all aspects. When someone like me has to make some publications and does not have a lot of time to try tools, he will be discouraged in using Matplotlib (and Python) and he will return to MATLAB again (and this is what happened to me until now). So, developers, please seriously consider adding this option to Matplotlib. The first sentence of the web site is "matplotlib is a python 2D plotting library which produces publication quality figures". This is true (I think they're better than Matlab figures) ... I only hope it will be more easy in the future also to actually use those figures in publications. Thanks to all of you.
