Trouble with Custom QTR Curves

2016-04-07 by artodd138@...

Hi Everyone,

I've just begun working with QTR and I'm having a bit of trouble creating my own custom curves. I've been working through the documentation that comes with QTR, however I fear that some of the tutorials are slightly dated. I was hoping someone on here could direct me to more recent tutorials on the process. Below I've outlined my setup and where I hit roadblocks.

I'm working on a Mac 10.11.3, Photoshop CC 2015, QTR v2.7.7, X-rite i1 Pro and i1 Profiler, an Epson 7800, and Piezography Special Edition P2 inkset. I'm able to install QTR and print with Jon Cone's P2 curves just fine. I want to try creating custom QTR curves for papers without Piezo curves available. Through the tutorials provided with QTR I am able to print the calibration sheet, determine default ink limits and crossover values for the 6 shades. Where I run into trouble is placing these values into the text file and then creating the curve. Supplied with QTR there are no ink descriptor files that are close to the set up I am using and I've tried to use something relatively close, but I am still unclear as to how to properly edit the file for this workflow. I'm also confused as to how to then create the curve from this file. I have not had luck dropping it onto the Drop-Quad-Profile droplet. If I simply place the text file into the appropriate folder and run the install command it will create the curve and I am able to use it, but I'm not sure this is the preferred method.

Any insight would be really helpful.

Thanks very much.
Andy
