Received my PiezoDN license today and I am thrilled to see digital images printed in the darkroom! I am printing on K7 selenium inks on the Epson7880-piezodn driver, using the x800-x880-piezodn-silver curve, 16bit, 2880dpi, unidirectional (just as with normal K7 prints). gamma 2.2.
I do notice that the negatives are rather grainy, which also shows in the print. I’ve always found that quadtone RIP provided a subtle grain, compared to say AWB using the OEM - this grain structure seems to be more amplified with PiezoDN though. Is this to be expected? Printing using narrow plate gap. When I print using K7 inks on harman gloss baryta I also get a subtle grain (much more subtle than PiezoDN). I remember contacting Wells about this last year, and he suggested it could be due to overinking - I’ve tried a range off different curves that Inkjetmall has send me through the times, but I always get variations of this grain structure (also got this structure with OEM inks using Quadtone RIP).
It’s been something that always bothered me abour the process, and kept me from making smaller prints - I’ve always had this issue whenever I used quadtone RIP - epson 3880 (OEM/Piezography), epson 4900 (OEM), and epson 7880 (OEM/Piezogpraphy). Never had the issue with AWB on any of these printers.
I am wondering if this is just inherint to the way Quadtone RIP lays down ink? But wonder why the effect is pronouneced with PiezoDN?
