QTR GUI settings for 3MK-R1800?

2013-10-25 by <paulmwhiting@...>

I'm using a different R1800 now and somehow my prints are lighter. Do these printers vary somewhat? My nozzle checks are good, the PK,MK and GLOP cartridges are using Eboni ink, the others contain Paul's C6b base fluid. I noticed the Advanced Settings are:

Ink Level: -20
Gamma: 0
Dither Algorithm: Ordered

I've never touched these, at least intentionally. Is this where they're supposed to be set? Oh, and I'm using QTR version 2.7.0.0.

I'm not using the Gray Gamma 22-toQTR.tif. I used to use it but somehow my prints have always been fine without it. Perhaps that's heresy!

My workflow on this particular print I'm printing is that I started with a color digital file and then adjusted the channels to 60/40/0 Monochrome. If necessary I'll pull in the ends of the Level Adjustment. But the print I made with my earlier R1800 has deeper blacks and more midtone contrast ... same file, I haven't changed it.
