Re: Issue creating R800 profile using gloss optimizer

2006-12-17 by mattchapin2

Hey Tom,

That is exactly what I did.  I entered these points in my gloss 
optimizer curve:

0,30 <- 30% glop at pure white
60,0 <- ramp down to 0% glop at 60% gray
100,0 <- keep it pegged at 0 for dark areas.

However, when I print with this profile, what I seem to get in the 
printer output is:

0,0 <- No glop at pure white
1,30 <- 30% glop at the very lightest shade of gray
60,0
100,0

So close, and yet so far!  This seems to be an issue with the QTR 
print driver. 

Matt
