I'm currently disassembling a bunch of canon-print files to get the canon part
of the print plugin working.

The color pattern I'm printing contains 8 intensity levels each for CMYKRGB. Is
this amount of colors sufficient for producing color-transfer information or
would we need more? Are there any standard methods for reverse engineering
color-management data? Any tools for extracting the data from the print
files? I've started to work on one for the canon stuff but would happily use an
existing one ;-)
