Yes, this is probably a widespread problem for PIXMA printers: I encountered the same issue with my MG3100.

[Bug 1181884] Re: Canon MG6200 printer driver has incorrect default color model
Here's another example - photo taken as carefully as I could (with proper white balance) - on the right is the original image, top left a CMYK version printed and below an RGB version printed. What is most revealing, I think, is the white to black gradient on the bottom left of each image. Although the CMYK model doesn't have as high contrast, it is at least a pretty accurate ramp, whereas with the RGB model something clearly goes very wrong a quarter of the way into the black end. This really needs to be addressed - it looks like it probably effects an awful lot of people! ** Attachment added: CMYK vs RGB printing using CUPS/PIXMA https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1181884/+attachment/3980048/+files/printingtest.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181884 Title: Canon MG6200 printer driver has incorrect default color model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1181884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Having the same problem but with Canon PIXMA i4700 printer (and appropriate driver). My test-pages for RGN and CMYK look exactly like those attached in OP by Gumwise Samgee, so there's no point in attaching mine. The RGB behavior and color-rendition in Lucid (64-bit on my end) was and still is correct. Confirmed the bug in 12.04 and 13.04 both 64 Bit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181884 Title: Canon MG6200 printer driver has incorrect default color model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1181884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
