Canon LUCIA PGI-72 Yellow Ink Tank

Don't know. I would ask the pros at B&H. I do know that the ink from a previous canon printer should have worked with my Canon TS8200, cause they are the same shape and everything, but no there is one small tip of plastic that makes previous ink not work. So ask B&H. But I would say they won't.

The Chroma Optimizer, CO, has nothing to do with the Black cartridges. CO is a clear coating and has not pigment or color.

These pigmented inks are made NOT to fade. When these inks are used with paper that doesn't have optical brightening agents you get prints that are archival that last 40+ years without fading (when not exposed to direct sunlight).

Thanks

Don't know.

PGI-72 Chroma Optimizer Ink Tank

I'm sorry, after checking I found it is 14ml.

Complicated...but I think same image uses twice as much pigment for 11x17 than for letter size and for B&w heavily black print far more pigment will be used than for a print that's mostly light...can be shocking.
