Re: QTR and ICC for softproof only

2006-09-14 by Shilesh Jani

Hello Roy,

Sorry to bug you with some Q's. I have yet to use the ICC facilities 
with the QTR system, and I am intrigued enough to try. As you know I 
use QTR for my b/w printing. I create the hue purely visually, 
without aid of an instrument. I linearize the curve with an old film 
densitometer. I do have access to an EyeOne machine, which I have 
used to make color profiles for PhotoShop and Epson driver. I am on 
a PC system.

Let us say (1) I print the 4x21 step file using my choice of 
linearized curve with QTR, (2) measure with EyeOne, and (3) create 
the profile with Create ICC.

Q: Can I use the resulting ICC profile for printing using PhotoShop 
and the Epson Driver? 
Q: Or is it good only for soft-proof?

Best regards.

Shilesh
