For printing of photos edited in GIMP we recommend adopting a color management workflow with late binding to CMYK by adopting PDF/X[1] worflows [2]. GIMP is already used successfully by many users with such workflows. For cases where late binding workflows are not possible the GIMP 2.10 series will hopefully gain both support for and good control over CMYK separation when exporting for instance to TIFF; integrating functionality that currently is possible with additional third party GIMP plug-ins. There might be future improvements to how GIMP deals non-RGB data in the 3.x series or beyond, probably including direct support for opening/importing CMYK files without a conversion to RGB - adding such capabilities should be more easily possible now that image processing is abstracted away and encapsulated in GEGL ops. When it comes to more radical departures from RGB, I've personally worked on, and have plans for continued work on code experiments with color that eventually might lead to CMYK being just one of possible sets of plate configuration for process inks / spot-colors / paints used for any simulated duo, tri, quad(or more)-tone print plate configuration for various colored substrates - using spectral characterisation along the lines of [3]. 1: https://en.wikipedia.org/wiki/PDF/X 2: https://www.scribus.net/svn/Scribus/trunk/Scribus/doc/en/pdfx3.html 3: http://www.color.org/CxF_test.xalter With regards, Øyvind Kolås -- http://pippin.gimp.org/ https://patreon.com/pippin _______________________________________________ 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
