Hi Paul, Thanks for the reply. Sorry if I have confused you, but I am trying to make warm toned prints on matte papers. Your 1400-profile.zip only has .icc for glossy type papers, hence my trying to make new icc for the matte paper I am using. I tried the following three curves applied to an adobe RGB converted 21-Step_0-100_L16_GG22.tif: UT14-Matte-N-1.acv UT14-Warm-1-MHW.acv (Example link: http://i.imgur.com/Y6KWm.jpg) UT14-Warm-2-MHW.acv (I assumed MHW means matte heavy weight) I print them by: -Printer manager color -Printer chose icc - adobe RGB -highest print quality On the darker levels the printed step wedge just didn't show distinct enough lab values to be used in the QTR-create-icc-rgb script. I ended up making the icc by skipping a few steps. Here is my example from the QTR-create-icc-rgb output: QTR-Create-ICC RGB version 2.7.2.0 File: /Applications/QuadToneRIP/ut14-matte-w1-out.txt Step Dens Lab A B 0.00 0.081 93.00 0.00 0.00 - b L + 5.00 0.130 89.00 0.00 0.00 - b L + 10.00 0.180 85.00 0.00 0.00 - b L + 15.00 0.220 82.00 0.00 0.00 - b L + 20.00 0.288 77.00 0.00 0.00 - b L + 25.00 0.345 73.00 0.00 0.00 - b L + 30.00 0.436 67.00 0.00 0.00 - b L + 35.00 0.517 62.00 0.00 0.00 - b L + 40.00 0.603 57.00 0.00 0.00 - b L + 45.00 0.775 48.00 0.00 0.00 - L b + 50.00 1.021 37.00 0.00 0.00 - L b + 55.00 1.324 26.00 0.00 0.00 - L b + 65.00 1.355 25.00 0.00 0.00 - L b + 80.00 1.387 24.00 0.00 0.00 - L b + 85.00 1.454 22.00 0.00 0.00 - L b + 95.00 1.489 21.00 0.00 0.00 - L b + 100.00 1.638 17.00 0.00 0.00 - L b + WARNING: None of the RGB curves are in ascending order.

Created ICC file /Applications/QuadToneRIP/ut14-matte-w1-rgb.icc My question is, how do I print a better initial step wedge that shows better separation on all 21 levels? --- In DigitalBlackandWhiteThePrint@yahoogroups.com, Paul Roark <roark.paul@...> wrote: > > feedthefoon <feedthefoon@...> wrote: > > > ** > > > > > > I have recently got the UT14 set and was quite happy with the prints just > > using Epson driver - grayscale.
