RE: Third party inks for negative printing


Ink with a high density (opacity to UV) is a good thing. First of all if I am not mistaken most Epson printers vary dot size and spacing, not simply spacing. That helps with smooth gradation in the light part. Second, by applying a curve or line that limits the density to say 80 or 85% (whatever you test will tell you is appropriate for your printing workflow) you simply reduce the amount of ink. I process all my work in 16bit and find that even most severe adjustments create little or no artifacts. Last time I looked at it, MIS was also selling a diluent for the black ink, so you could make the ink that would have DMAX that suits your needs prefetly. Or mix your own combination of inks (say yellow and cyan), load it in a Black cartridge and print in a B&W mode, which uses only black cartridge. I use my printer to print color, B&W (black ink only, MIS eboni ink) and digital negatives, mostly for palladium and gum. And the one 2200 Epson printer and ink set serves all my needs perfectly. Way back I started with photoblack for everything, but that was before I discovered how nice of a B&W print can be made with eboni ink. I use only photoshop and Epson drivers, but with additional software you can address individual ink cartridges as well.
