color profiles are controlled in part by specifications not on the user log in , in order to make a global change in color management some of the problem is in translation of the icc profile.
case in point, trying loading new ICC profiles through the user share and then open another CMYK capable program.... it crashes some of them because even though the profile is there ...the correct linking on the program is not. This could only be done being root and knowing what to do to link the specific color profile, usually defined sometimes in xml files... little cms only has certain ones that even though they are near close to adobe they are not prescribed to the program through the links of having the color profile alone....other configuration must be done. in other words it is not that it is not working..... at this point there isn't an integration completely of Adobe profiles ...ISO WEB COATED is almost completely the same as the adobe SWOP v2 for offset printing and nearly the same name ....but it is not completely just as photoshop ingrains itself in the OS so does Krita ....so some user changes cannot be made to make the profiles work even though it seems possible its part of a larger change that needs to be made....its possible it falls in to changes made while logged in as Root. It would be quite the time consuming process to add to the pre packaged linux color profile system that is somewhat linked to cups. Right? its better to go outside of a program that creates documents in a particular CMYK mode and just go to the throat by finding a suitable program to open them with such as a PDF program ... or one that edits PDF or use a service to convert RGB to CMYK after the document has been shared before print it's almost asinine to share CMYK documents instead of RGB ones before it goes to print Its neither going to look the same as print on a monitor or effect it on a high level if viewed as RGB before print conversion is made later .....in fact it makes more sense to use sRGB space and share it that way so editing can be done to make it CMYK just before print.... being able to Preview CMYK on a monitor can be done by simply dropping percents of Black so it is not Pure black and removing Pure White so none of the colors are impossible ones.... you can proof against a color profile in Gimp and see what it looks like while its still sRGB it will mark the out of gamut colors or simply convert it to CMYK in Krita Mind you that most people can only open image files in 8 bit channels anyway and higher levels such as 48 (16) bit require you have the same software anyway.......you end up diluting the image in some sense by hoping programs. PDF is still the better way of looking at it because it punches out the flaws of sharing. PDF works all around for images both Open Source and PC and Mac all recognize it. You can color manage FireFox now for goodness sake quit relying on obtuse methods for viewing an image in colors you do not need to with a program it wasn't meant for. -- Bad management of CMYK files (detected as RGB) https://bugs.launchpad.net/bugs/81099 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to koffice in ubuntu. -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
