Re: [QuadtoneRIP] Gray-lab profile in PS color settings

2006-02-09 by Paulo Baptista

Hi Roy,
Yes, I thought so, but on reading the "Mini-Tutorial on Curves" (which is 
available on the list's files section), I found the following, on the 
section that refers to linearization:  "In the Eye-One folder, open the 
Step-21-random.tif file file in Photoshop, with your gray working space set 
at QTR Gray Lab (...) In Print with preview, select QTR gray matte for 
print space(..)". That quote really confused me a lot, so
I thought I'd better ask the list for advice.
Thanks again,
Paulo
