Re: Piezo NK7 vs R220 UTR2 W vs C86 EZW

2006-01-15 by joshhackney

Michael,

If you don't have the ability to create your own profiles using QTR-create-icc, then you 
need to be using Grey gamma 2.2 as your working space, and print with no color 
management from PS.  If you have a densitometer or spectrophotometer, I HIGHLY 
recommend using the IJM supplied curve for linearization, and then make your own 
profiles.

Good luck.

Josh
