Re: Neutrality, and shadow separation

2006-03-23 by Helen Bach

Thanks for the reply.

I'll try other media settings. I'd like to try to understand how the
media settings affect this. If a 0,0,0 pixel gets printed as a square
with an L* of 2.5 and an 18,18,18 pixel gets printed as a square with
the same L*, where has the media setting come in? Too much ink? 

The above example comes from the profile with no adjustments. I am
using the Epson Premium Glossy setting for Epson Premium Glossy paper.
I've checked the spectro against my calibrated TR924 densitometer, and
they agree closely.

Best,
Helen
