I can tell you that the Canon imageCLASS printer driver performs some “black
box” adjustments in the printer driver that cannot be turned off, and
therefore, custom profiling isn’t possible. I’ve spent some time with Canon
engineers to confirm that this is the case, and to make an argument for custom
profiling. It sounds like they are doing the same thing with the imageRUNNER
printers you are working with. *Really* unfortunate!
Now I can tell you that the Canon imagePRESS printers have excellent color
management and consistency through the EFI RIP. The print quality is also
amazing - they are doing something unusual with the toner on those printers
that translates into impressive color gamut and a complete elimination of
mottling on textured media.
We’ve gotten to a point where we can can’t just buy a printer and assume it can
be color managed. The landscape with toner printers is espicially challenging
these days. Doing some comparative analysis before purchasing has never been
more important. I’ve recently just completed an analysis of desktop laser and
midrange toner based presses - email me if your interested in the results.
