Re: [QuadtoneRIP] Step Wedge Tool & Kodak Q-13

2016-09-15 by Paul Roark

I tried the Stepwedge tool yesterday with PS CC, and it works fine. I9;m on Win7, but I assume it'll work the same with a PS CC on a Mac.

Has anyone tested the step wedge tool with Photoshop CC?


I have not used it for a (long) while.


That question caused me to be curious if my old Kodak Q-13 gray scale guide was sill any good. So, I measured it with the Spyder3Print. The graphs of the Lab L and Density are posted at http://www.paulroark.com/BW-Info/Kadak-Q-13-Gray-Scale-Lab-Density.jpg

It looks rather linear with respect to Density (not Lab), and the values are that same as they were when I first bought the guide (within my "spectro's" accuracy). There are a few bumps, that they showed up on both of the two separate reads I did to get the Lab L and Density.
