Description of problem: Printing a colour photo with a Canon Pixma MP540 showed loss of Yellow colour compared to the screen and to a printout of the same photo with Windows XP, i.e turquoise appeared as blue. System used F20, LXDE desktop, gutenprint-cups 5.2.9-14.fc20, printer setting cmyk colour. Version-Release number of selected component (if applicable): gutenprint-cups 5.2.9-14.fc20 How reproducible: printing again the same photo Steps to Reproduce: 1.print a photo containing also turquoise colour 2. 3. Actual results: turquoise printed as blue Expected results: turquoise printed as turquoise Additional info:
Does a test page show correct colours? Also, what output do you get from this command?: sudo escputil --new -ink-level --raw-device /dev/usb/lp0
The test page seem to show correct colours. But it is hard or nearly impossible to identify turquoise on the test page. The command "escputil --new -ink-level --raw-device /dev/usb/lp0" seem to be for Epson printers - I have a Canon. Wether the command "escputil --new -ink-level --raw-device /dev/usb/lp0" nor "escputil -ink-level --raw-device /dev/usb/lp0" did work. Possibly an Epson Stylus is expected. I used Copy - Paste, did I use this command in a wrong way? I tested now to print turquoise from the following page "http://home.arcor.de/pierrezimmer/bilder/herbol/farbwahlwand/tuerkis1.jpg" Printing with firefox showed the correct turquoise colours. But printing with GIMP, where I have chosen "print with Gutenprint" showed blue instead of turquoise - The foto where I wondered about turquoise resulting in blue colour, I printed also using GIMP. Is this a GIMP problem? Not a Gutenprint-Cups?
Sorry, the escputil is for Epson printers, yes. When you print using 'Print with Gutenprint', please look at the 'Output' tab and click 'Adjust Output...'. Have you previously adjusted any of these settings? Are they as they should be? If you aren't sure, please click 'Set Defaults', close that window, and try printing again. Another thing to try is to download tuerkis1.jpg and print it from the command line: lp -d thequeue tuerkis1.jpg (replace 'thequeue' with your print queue name). What results do you get from the above tests?
I did the 2 tests You proposed. Both resulting in blue colour, expected was turquoise colour. First test: GIMP - print with gutenprint Printer Settings: Canon PIXMA MP540 Media Type: Plain Paper Media Source: Cassette Resolution: 600x600 DPI Ink Type: CMYK Color Ink Set: None Print Quality: Standard Output Type: Color There is no further 'Adjust Output' button Second Test: [root@localhost joerg]# lp -d Canon-MP540-series /home/joerg/Pictures/turquoise.png request id is Canon-MP540-series-155 (1 file(s)) [root@localhost joerg]# Printing itself was in both cases ok, but I got in both cases the wrong colour. I used the admin account (su), which I do sometimes, when I don't know, if a test will run on the normal user level.
Please attach /etc/cups/ppd/Canon-MP540-series.ppd using the 'Add an attachment' link above. Thanks.
Created attachment 922430 [details] /etc/cups/ppd/Canon-MP540-series.ppd after "turquoise print" according to needinfo
I've asked about this upstream: http://sourceforge.net/p/gimp-print/mailman/message/32663922/
Here's a test build with a change from upstream: http://koji.fedoraproject.org/koji/taskinfo?taskID=7219081 Are you able to try that out?
Created attachment 923116 [details] /etc/cups/ppd/Canon-MP540-series.ppd after the print with the test build ppd file after print trial of printing turquoise colour after installing the build of gutenprint
I have downloaded and then installed the following, see installation protocol. The result in a print trial of turquoise is blue colours not so dark as before installing the test build, but in no way turquoise colour, which I wanted.

Created attachment 923270 [details] print of turquoise colour via gutenprint-cups-5.2.9-16.fc20 and via firefox in the attachement I show an example printout of an example of a turquoise colour with GIMP, "print with gutenprint" branch. And an example of the same turquoise colour printed with firefox. Both printouts in the same software environment, but I don't know, which printer driver uses firefox, I only chose in GIMP and in Firefox the Canon Pixma MP540 printer.
I tried to print "blue colours" (Cyan, Turquoise etc) with F21 Beta TC1 using Libre Office Writer. All Cyan and Turquoise is printed in more or less dark blue. Printer is the same - Canon Pixma MP540.
(In reply to joerg.lechner from comment #11) The print from Firefox and GIMP seems to demonstrate printing the source color (P2.20.73) correctly is possible; and assuming the user print settings were identical in the two applications, it suggests one or more bugs (just because FireFox produces the intended color doesn't mean it's bug free, there can be counteracting bugs). Is there a way to intercept and get access to the (pdf?) spool files from both applications? I'd like to see what the objects RGB values and /ICCBased color space are from the two applications.
I am sure that it's possible to supply the requested data. My problem is that, I need a more detailed "how to". I am not so firm in the file structures etc. My tests are tests of a user not expert. Currently I have a fresh install of F21 Final TC4 for testing purposes only. How shall I intercept? Where can I find the spool files? gutenprint 5.2.10-5.fc21 x86_64 kernel 3.17.4-300.fc21 x86_64 firefox 33.1-2.fc21 x86_64 gimp 2.8.14-1.fc21 x86_64

Created attachment 961524 [details] Tourquoise Colour prints Gimp on F21 Final TC4 and Win 8.1 There are 3 prints of Tourquoise colours A) Gimp, "print with Gutenprint" button B) Gimp, "print" button C) Windows 8.1, program Irfanview F21 SW versions as told in comment 14. Before going on further, I have to study the "How To" of comment 15. I can say the printer driver (or something else) used by Gimp clicking on the print button (B) seem to be ok. The printer driver (or something else) used by clicking on the button "print with Gutenprint" (A) doesn't mix Yellow colour, to that, what should be Tourquoise, therefore this printout is something like blue. All printer drivers were set to CMYK colours. All printouts are on glossy foto paper. Further on I didn't have daylight while taking the fotos.
Tried in addition other programs: Firefox printing with CMYK Turquoise print ok Firefox printing with RGB Turquoise is printed blue nok Shotwell result is the same as Firefox: Print with CMYK ok, RGB nok Libre Office Draw: "print from driver" or "print color" both print Turquoise as Blue nok
I have done now a driver check. Normally at installation time the cups driver "simplified" is used. In this driver You can not make a colour adjustment. I tried the driver: "Canon MP540 series - CUPS+Gutenprint v5.2.10" (not the simplified one). There is a menue "print options" (in my case German "Druckeroptionen"). Most data in the menue are not prepopulated. I took i.e. for Cyan 1000, Magenta 1000 and Yellow 2000, the print in Gimp with "print with Gutenberg" was better. But only a printer colour expert can populate these data. I think the error is, that these data are not prepopulated and in the installation the wrong driver version (the simplified one) is advised. I did only a test with Gimp, but I think for the other applications it will be the same.
Hi Tim, is it possible to get again a testbuild like You did in Comment 7/8? I don't know, if I did the test in F20 with Canon MP540 series - CUPS+Gutenprint v5.2.10" (not the simplified one) or with the simplified one. I would like to try this again with the "not simplified" one and try to set some different percentages of colour combinations and then print turquiose colours, changing the colour combinations percentage is not possible with the "simplified" driver version. Thank You in advance.
Sorry I didn't say, testbuild for F21 (currently Final RC1). Otherwise I would have to install again F20 (is also possible, if I can't get a testbuild for F21).
I tried again Fedora 20 (according to comment 7 and comment 8. Also tested with F21 Final RC5. All Turquoise is still printed Blue
I deinstalled all, what is named Gutenprint and tried to print with Gimp via the menue "print" (not "print with Gutenprint"). Printing was not possible. Does anyone know, which printer driver -especially color settings- is used printing with the Gimp "print" command? Reason: Printing with the Gimp "print" command, Gutenprint installed, gives turquoise colors very much better, then printing with Gimp "print with Gutenprint", which doesn't give turquoise colors. My system is as it was, when I started filing this bug (printer Canon Pixma MP540, OS Fedora, currently F21 Final RC5).
I wanted to write an attachment with the ppd file of the "successful" print of turquoise colour with the Gimp menue "print", but I could'nt make this attachment, possibly my fault. The Gimp menue "print with Gutenprint" still doesn't print any variation/mixture of the colour blue(with Yellow or Green). For me this result is sufficient. I use the Gimp menue "print" and not "print with gutenprint". Via deleting and inserting the ppd file again, I got the impression that both print menues in Gimp use the same ppd file. Is this a Gimp error? Or a Gutenprint error? I have saved the ppd file, if anyone is interested in.
Possibly if you post to the openicc list someone might have advice on how to further test this to isolate the problem. I don't expect much in the way of response in a non-upstream bug report because there are too many pieces involved and a specific bug hasn't been identified. I'm not convinced whether this is a gutenprint bug. http://lists.freedesktop.org/mailman/listinfo/openicc
Faulty file localized. gutenprint-plugin 5.2.10-5.fc21 x86_64 Tested the following: -Installation of F21 Final. -Installation of nearly all "Gimp files", all what seems to contribute to Gimp working, except gutenprint-plugin. -Starting Gimp, there was only the menue button "print", no "print with gutenprint" -printed on glossy fotopaper a turquoise colour scheme. Colours ok. -installed file gutenprint-plugin -started again Gimp -now there is the menue button "print with gutenprint" -print with this button -> colours faulty Used Driver in both tests: stp-bjc-MP540-series.5.2.sim.ppd
I have an additional question: What should "gutenprint-plugin" make better in Gimp? Currently "gutenprint-plugin" -at least for some Canon printers- can be omitted, it's useless. As I have seen the "Gimp option" "print" uses the same driver as the "Gimp Option" "print with gutenprint" (when gutenprint-plugin is installed), but "gutenprint-plugin" in the Gimp Option "print with gutenprint" doesn't work ok. Is there any use of "Gutenprint-Plugin" in Fedora 21?
Just tested Fedora 22 Beta 3 (Beta Release). It is still not possible to print turquoise copours with the Canon Pixma MP540. But F21 Final does print turquoise colours with Gimp ! I hope that F22 Final will print turquoise colours as F21 does.
Now F22 is short to freeze for Final (F22 TC3). Tested printing Turquoise colours with Libre Office via Canon Pixma MP540. Turquoise is still printed as Blue. Here F22 is worse than F21. I fear, I have to use for Foto printouts or else Grafic work still F21 instead of F22.
It's rather unlikely gutenprint is to blame because it's the least changed item in the printing pipeline release to release. CUPS maybe, but it doesn't directly have anything to do with color space conversions. More plausible is some sort of change in either the application, how it submits data, or ghostscript although its RGB source/destination space assumptions were changed a while ago, I think before Fedora 21. Anyway, it's tedious and annoying to troubleshoot, but it's going to need to be finer granularity than turquoise prints blue. If the turquoise is specified CMYK, I'd have every reason to suspect it's going to get converted somewhere to RGB in the pipeline because pretty much all consumer printers these days want RGB data. So either the application, ghostscript will do that. I know the gutenprint printer PPD should say what space the printer wants, I'm not totally sure how CUPS decides what to do based on this if it somehow gets ghostscript to do that conversion. But what you're describing turquoise to blue, is hue torquing, it's quite common when either the assumed source space or destination space are wrong and a conversion (from source to destination) is happening. If the turquoise is RGB, then that suggests an RGB-RGB' conversion. This sort of thing doesn't ever happen by default on Windows, but can happen on OS X, I don't know whether or how it'd happen on Fedora. But I'm willing to bet dollars to donuts you can get the same version of gutenprint on Fedora 21 and 22 - either the 22 version on 21, or the 21 version on 22, and in that way isolate whether or not it is in fact gutenprint related. If not, then it's app vs CUPS vs ghostscript to isolate next.
You are right, I think it's my error. Program tested GIMP, print button: "print" (not "print with Gutenprint" !) cups 2.02-5.fc22-x86_64 Printer settings: 1) Extended- Printer Features Common: Ink Type CMYK Color (no RGB setting possible) 2) Color Color Model: RGB Color -> test result: turquoise printed blue CMYK -> test result: turquoise printed turquoise Thank You for Your help in understanding color printing!
Hue torquing doesn't happen when printing with Color Model set to CMYK, but does happen when it's set to RGB. That's unexpected. It suggests one of two things: - RGB source and destination are the same, there is a null transform in the print pipeline, and the torquing is happening within the gutenprint driver. This is unlikely because: gutenprint-5.2.10-7.fc21 gutenprint-5.2.10-10.fc22 I'm not sure if the difference between these, but I seriously doubt that any lookup tables in the print driver have changed, it's probably minor packaging differences since the gutenprint versions are actually identical. - RGB source and destination are different, and a transform is happening in the print pipeline before getting to the gutenprint driver. This is plausible because: cups-1.7.5-16.fc21 cups-2.0.2-5.fc22 That's a fairly significant change, and I vaguely recall color management related changes between 1.7 and 2.0. ghostscript-9.15-6.fc21 ghostscript-9.16-2.fc22 Seems minor, but there's a large pile of changes between these versions. http://www.ghostscript.com/doc/9.16/History9.htm Since there's no incompatible changes, it might be worth going to Fedora 21, and seeing if you can install ghostscript-9.16-2.fc22 only, and print again to see if that changes things or not. Only then is it really worth going through that changelog to find out what might explain it.
Have now tested fc21 the same way as fc22 (Ghostscript 9.15-6.fc21, Cups 1.7.5-15.fc21, Gutenprint 5.2.10-5.fc21, all x86_64). My information so far was incomplete. The test result with fc21 is the same as with fc22. Printer Canon Pixma MP540: Color Model CMYK Ink Type CMYK Test Result Turquoise -> printed as Turquoise Color Model RGB Color Ink Type CMYK Test Result Turquoise -> printed as Blue Sorry for this. If this (RGB versus CMYK) is an Ghostscript error I can do further tests, when You tell me, how and what to test. I have 2 testsystems, one external disk fc21, the other external disk fc22.
