Ubuntu 15.04 has successfully recognized my All-In-One printer+scanner Canon PIXMA MG3550 as a Canon MG3500 series.
Scanning and black-and-white printing are correct :-)
But color printing does not produce the right colors :-(
As I do not find (or I do not know how to find) an ICC profile for my system, I tried to understand printer calibration, to use Argyll and also to install a GUI ([gnome-color-manager).
But it is too complicated, I am a beginner in color calibration!
Therefore, I am looking for a simple intuitive graphical tool to:
Print a complete CMYK
color reference test card/chart
Scan the printed result (assuming the scanner is calibrated)
Compute (and install) the ICC profile
Repeat again until the ICC values are sufficiently stabilized
If no such tool exists on Ubuntu, I can download a recommended test image, run some command lines and manually install the new generated ICC profiles. Is there a website briefly providing these steps?
