Bug#763517: patches breaking color management
In fact no, it is not fixed it was a testing procedure on my side. Sorry! How to reopen this ticket? I have attached a picture of the wrong output from Debian (CUPS 1.7.5) and the correct from Ubuntu (CUPS 1.7.2). We clearly see the purple color cast on the print from Debian (the base picture is BW).

Hi Pascal, Yes, as Didier mentioned, any details regarding your print color management setup -- including the color manager you are using (whether you are using colord or Kolor Manager) -- would help us. I do see the purple shift, where if you were printing in black-and-white mode, should not be there.

Bug#763517: Info received (Bug#763517: patches breaking color management)
After upgrading to 1.7.5-4 on Debian/sid I cannot reproduce this issue even though there is nothing to explain this. Maybe a transient issue on color management on Debian/sid? Anyway, I think this can be closed at this time.

I assume that you are using the latest version of cups-filters? Yes, I was using CUPS 1.7.5-2 with cups-filters 1.0.58-1. (…) Let me know if something is still missing. You need to answer the what filters are you using to print? question. You mentioned Epson 3880, so we're guessing you're using the following driver: ? gutenprint.5.2://escp2-3880/expert Epson Stylus Pro 3880 CUPS+Gutenprint v5.2.10 You mentioned with an home made profile; could you make it available and explain how you configured it?

Bug#763517: patches breaking color management
Package: cups Version: 1.7.5-2 Severity: critical I've been chasing this bug since some time now. The issue has been discussed in the CUPS and printing-architecture mailing-list. For the context. I'm printing on an Epson 3880 since 2 years with an home made profile. And recently I found that my prints were really bad. After investigation I found that reverting to CUPS 1.7.5-1 from testing fixes the problem. I have then found out that one difference with 1.7.5-2 is that the ColorManaged option is now listed as CM-Calibration in /etc/cups/printers.conf. Looking at the GNU/Debian change between 1.7.5-1 and 1.7.5-2 I think that the culprit is the following: [ Till Kamppeter ] * Updated color management extension patch to the newest version from Joseph Simon, especially to fix PPD updates via the web interface (LP: #1362321). (http://metadata.ftp-master.debian.org/changelogs//main/c/cups/cups_1.7.5-3_changelog) It should probably be removed or fixed as it does not only fix the PPD updates via the web interface but also breaks color management done down the piper by the filters. Please let me know if you need more information. I can also do some testing but I've already wasted lot of paper and ink :) Thanks, -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://v2p.fr.eu.org http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Hello Pascal, More information might help in assessing the issue. What filters are you using to print? I assume that you are using the latest version of cups-filters? Joe Simon
Bug#763517: patches breaking color management
Joe, What filters are you using to print? I assume that you are using the latest version of cups-filters? Yes, I was using CUPS 1.7.5-2 with cups-filters 1.0.58-1. I'm full up-to-date on unstable. And this was not working. After I reverted to CUPS 1.7.5-1 (and still using cups-filters 1.0.58-1) I had correct color rendering. And I found out that the almost only visible change related to color rendering was the CM-Calibration option in 1.7.5-2 vs ColorManaged in 1.7.5-1 in /etc/cups/printers.conf. Let me know if something is still missing. -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://v2p.fr.eu.org http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
