Re: Dithering in the lighter tones with Piezography inks

Roy,

Thanks for your response. The version of ProfileMaker I downloaded 
was 5.5. I've since gotten fairly proficient using EyeOne iShare for 
my readings.

The dithering problem I finally solved, after numerous combinations, 
by using Adaptive Hybrid and Better. I'd still be happy to send you 
the .qidf  if you'd like. Perhaps you can suggest some improvements. 
I'm still trying to figure out the ins and outs of the software.
