Thanks for that insight. The tinting is the reason I found Quadtone RIP.

I still use the Epson PK since I print on glossy(photo) substrates and Jons' black is for matte. In our exchanges I mentioned the fact that I was getting a very slight magenta cast and going through a lot of Lt Magenta when doing B&W. His reply kind of opened my eyes a bit.

Assuming I replace the cart with fresh ink, what procedure should be used to clear or drain the line of the old ink?  Thanks for any ideas.
