As I am now essentially fully converted to Image Specialists inks in my Canon PP9000 Mk II, I notice a very slight warm tone that custom profiling will not fix. Just wondering...

Were you using custom profiles before the switch?

No Brian, probably not. Another good observation.

An expensive proposition: swapping in OEM cartridges, reprofiling, then looking at the comparative results to see if the earlier prints were a little cool. You could try the profiles you were using with the earlier prints and see how they compare with the inks you are now using.

Bob’s hypothesis of ink aging appeals too, you are using dye based inks, which do tend to change more rapidly over time than pigment inks.

There were a few posts on dye shifting over time.

this was one with some data.
