Re: QTR-Create-ICC - Making sense of my results

2011-07-22 by pili

Mike,

This (http://pastebin.com/xj2TzYDj) is the output file and this (http://pastebin.com/3Nqzj7sS) is the data that originated it. Here (http://pastebin.com/m79ZxEqU) are my measurements after applying the profile.

I'm using the Epson ABW driver for all this.

There's a dent near the 95% tones, indeed. 

Thank you,

Fabio Pili
