RE: Third party inks for negative printing
Kees, The Epson K3 MK and PK blacks are very dense for UV as well. I would also point out that MIS Eboni black is sold as MK and PK as well. Perhaps the PK would dry differently, though truthfully I have no idea. It's been my experience that the MIS inks (colored and black) just don't dry well on Pictorico OHP and I don't see the advantage of having to coax the inks to perform well with that substrate. By coaxing I mean spraying or drying with a hair dryer. I do wish someone somewhere could make a survey of all of the available non OEM inks to determine if there is a non Epson brand that could be used for making inkjet negatives on Pictorico and other similar products. As Judy Segal pointed out the inexpensive dye based inks which can be purchased for printers like the 1160 or 1280 can and do work well for inkjet negatives. Unfortunately those printers don't print as smoothly as the new pigment ink printers but they do work fine for gum printing.

The problem is the huge UV density jump between the black ink and grey inks (and colored inks too). The grey inks are dilutions of the same ink and the blacks are different inks. I don't know if this is the same for the epson k3 inks. This difference is clearly visible when looking at the print especially with ebony but also with the mis photoblack. I think adding an extra tonercolor (a diluted yellow or green maybe) instead of black might help more. With an adjustable toner ink theoreticaly you can create your own digital multigrade system. But you need a dedicated printer for these BW negatives then. Nice thing is that these negatives look a lot more like the old analog ones we all still have sweet memories of. By the way this non black printing method gives great results with normal BW prints on glossy papers too. Learned this on the BlackandWhitedigital list some years ago. That's why I started using it for negatives too. kees So for loger scale negatives I use spectral colored On 26-okt-2006, at 17:15, Eric Neilsen wrote: > Kees, Have you tried limiting the black ink with QTR?
