Re: 1440 dpi vis-a-vis 2880 dpi

2015-09-08 by ascherjim@...

I have now set up something of a two printer test. (I print black-and-white using MIS Eboni-6 inks with my own dilutions currently using a five-ink profile.)

Printing at an approximate 13-inch by 17-inch size, I programmed QTR to print at 440 dpi on my new Epson 1430 and at (my previously used) 2880 dpi setting on my old Epson 1400.

The print quality on my matte paper (Epson Hot Press Natural) slightly favors (but only slightly) the 2880 setting. (Longer printing time but slightly subtler gradations of tone.)

I now notice the edge micro banding occurring in both, slightly less noticeable with the 440 dpi setting. When printing on the Epson 1400 over past years, I used a three-ink dilution profile, and with NO micro banding. Go figure.

So, I guess I will have to follow Brian's solution if I want to continue using QTR with the five-dilution profile, and set at 2880 dpi. However, I'm not quite certain, Brian, I fully understand your QTR settings to achieve this. Do I, for example, "tell" QTR I'm printing at 13 by 19 inches, but scaling the actual photo to 13 by 17 inches to eliminate the one-inch of micro banding at each leading edge?

All a bit of a nuisance, what!
