I will be looking at the Platine this weekend.
Actually the qtr driver for the 7890 does not have neutral curves, ( does the 3880? ) it has cool, warm, sepia, and selenium. That is why I was wondering if anyone had made one . The selenium on the matte media was of no use, even when blended. The cool really cold and the warm not good on Canson Rag Photo, but of course one could create one. The best I got was one curve warm and one cool. still a little cool. But this is on the matte rag. photo rag curves, I will try this combination blend on the Platine with the Ilford curves. That is what we used on the P800 that was so good I think.
What I was wondering is if you could use the three curves to do something or stick with just two. Like I said it's been about 15 years since I did any bw with epson inks and so the quality of the p800 with QTR really surprised me.
By the way the inkset is different on the P800, as with all the new sure color printers, it has the new yellow and the new blacks which give it more dynamic range. However, with my two printers I see no reason why one couldn't add the new blacks and the yellow with refillable carts and relineraize and reprofile.
