[Bug 1855615] Re: Device colour profiles - on / off button not working Ubuntu 18.04.3LTS
Had a panic moment when it appeared my i1pro meter had stopped working. It seems I had not used it since upgrading to 18.04.LTS when I started having problems with this issue.

[Bug 1855615] Re: Device colour profiles - on / off button not working Ubuntu 18.04.3LTS
Ok, so I was looking for an option like that but could not find it in any documentation. Just to add I was printing .ps targets from Argyll's targen / printarg / chartread / colprof workflow with: lp target.ps I did some more test prints and have attached the results again. The -o cm-calibration=1 option does seem to turn off calibration from "Device Colour Profiles" but the "color correction setting" in CUPS still has an effect on print output, quite noticeable on a couple of targets which go from orange to purple. I am going to create two profiles from targets printed with the -o cm- calibration=1 option with: a). Device Colour Profiles cms ON and a profile loaded, but Cups colour correction set to High Accuracy. b). Device Colour Profiles cms ON and a profile loaded, but Cups colour correction set to Uncorrected. Hopefully I will then be able to asses the best way forward. ** Attachment added: "printer output and screenshots" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1855615/+attachment/5312322/+files/printer%20output%20pictures%202.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855615 Title: Device colour profiles - on / off button not working Ubuntu 18.04.3LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1855615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To turn off color management on a CUPS print job you have to turn on calibration mode. On the command line it is done as follows: lp -d printer -o cm-calibration=1 file The option has the possible values 0 and 1. The button mentioned should probably add this option to the print job, or when it is not in the context of printing a job but managing a print queue it should set the default of this option on the print queue. The option is available for all printers (provided by cups-filters). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855615 Title: Device colour profiles - on / off button not working Ubuntu 18.04.3LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1855615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
