I see on this thread that some people propose using a 7900 with a rip (Studioprint or QTR) to partition multiple ink sets. As far as I m aware, Epson removed

I would guess from the Q in the printer description, that its for a specific monochrome inkset (Q standing for Quadtone) where all inks are shades of grey.

Tyler, Out of curiosity, while are you bothering with K3 on x900 if its such a banding challenge. Why not just use your 9880? If its to get easy PK/MK exchange

Hi Lester, The curves that you select when printing must be specifically designed for the inks you have loaded in the printer. It sounds like you used curves

Hi Mike, I have to warn that x900 banding could indeed be an issue for some. Many, including myself, are experiencing K channel banding and have yet to nail it

Hi Shilesh, As I mentioned above you can get a triple K6 on an x900 11 channels, but no Glop. I don t think you have to worry about banding with the 7900 -
