QTR-Quadtone RIP

Thanks Seth & Paul ...

Paul,

I've read the 3-4 PDFs and related links to using PK ink for the R800 / R1800 (ESCR800-4-PK) and other various combinations.

If I wanted to keep things simple, since I think I can work my warm LensWork type brown QTR curves to a more neutral black, and only use your PK ink in place of the Epson PK ink, use refillable cartiages, and print on Epson Ultra Prm Luster (I also been printing on Harman Gloss FB Al & a few sheets of Ilford Galerie Gold Fibre Silk, both of which could use less Gloss than I use for the Epson Prm Luster profiles).

What other items would I need to purchase to accomplish?  Would cleaning only the PK position be required?  What if I wanted to return to using the Epson PK cartiage?

As I understand the Dmax would be greater than 2.5 on Epson Luster and even higher on the other two papers?  I'm getting 2.2+ now measured on my X-Rite 810.

BTW - I'm printing at 2880, uni-directional, and adaptive hybird and getting very smooth results.

Thanks to you both for your response.

Terry Glass
