I'm not sure that converting images from RGB to CMYK and exporting to TIFF serves any real purpose. I used to do that - up until about ten years ago - but none of the print shops I have had dealings with since require it. PDF makes it a moot point, in the sense that print shops will not know the difference between a PDF file with embedded PNG or TIFF files. Monitors can only present RGB outputs; when editing a CMYK file, CMYK color is exported to RGB before the image appears on the screen. Accurate color adjustments to CMYK files are only possible if one has the production printer (or its identical twin) at hand to produce proofs; in that case one can print the image, tweak the image, print it again, tweak it some more etc. until the printed version is "just right" - even if it looks wrong when viewed on the monitor. Is it better to export an RGB image to CYMK format in one's own home or office, or to allow the driver that runs the printer at the print shop do it automatically? Allowing a software driver expressly designed to work with the printer producing the hard copy to do the conversion on the fly seems like a good idea in theory. In practice, I have seen no difference in the end product either way. Variations in RGB color presentation from monitor to monitor are a much more important issue either way. In a worse case scenario, i.e. your monitor is way out of calibration and the image you want printed reflects your monitor's presentation errors, the print shop people may have to make color adjustments after they see the proofs. (Here comes a big labor charge...) If they don't know how to convert your submitted files to CMYK, or believe / pretend that this imposes a hardship on them or takes more than a few seconds of work, a much bigger problem than a file format issue is present... :o) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
