| p.1 #9 · Problem with canon printer colors |
I don't know if it is even possible on your printer but is seems like the ink cartridges might be mixed up because it's one of the things you changed. They might print the test pattern correctly but with the colors in the wrong places.
To try to sort out what is happening I'd suggest creating a file in Photoshop with small blocks of 100% R, G, B and C, Y, M, K. Also create block of gray tones. Printing on plain and photo paper should give you a clearer idea of where the frigging is in the rigging better than a photo.
