Canon documentation on Chroma Optimizer on Pro-x000
« on: January 06, 2018, 02:52:18 PM »

Got a hold of this some time ago, and haven't stumbled upon it elsewhere, so will share it here. Provides some info on CO, how it works, how to control usage and some stats on how it affects ink usage on different media and settings. Nice paper. Would appreciate a lot more from Canon like this.

Useful paper, thanks Henrik. This didn't exist at the time we did the reviews, and was most recently revised I see in May 2017, probably reflecting the up-dated driver performance.

I got the paper in March 2017. Creation date for document file says May 2016. I hope to see more info like this on other topics like maintenance routines and media type differences. Especially the last part.

Useful info.  I would expect profiles would differ with and without CO based on their descriptions. Could be significant gamut increase. Anyone done tests?

What exactly is "Grossy Photo200?"

Yes, to profile these printers you need to decide on the CO regime before printing the profiling targets and then use the same regime for making prints with the profiles resulting from those targets.

Canon Glossy Photo Paper 200gsm.
Never tried it. How does it compare to Canon's Platinum Pro Glossy?

The gamut doesn't change that much, at least as measured by a regular spectro like i1Pro with idealised illumination, but color appearance "in real life" is more consistent when viewing prints from different angles relative to light source. Bronzing and gloss differential is reduced, but seldom eliminated on gloss(y) media. A nice step forward for pigment solutions.
