Profiling 4800 for Museo Paper

Profiling 4800 for Museo Paper

2006-05-22 by michael_mutmansky

I'm working of a profile for the new Crane Museo Silver Rag paper, and as this is my first 
attempt at this, I have a few questions...

When I measure the Ink Pattern steps, I get a measurable increase in density all the way 
out to 100% on the Black level, but the visual increase after about 85% is very small at 
most, or possibly insignificant.  85% is at 2.33 and 100% is at 2.48 with about .04 increase 
for each step.

Is there a benefit to setting the default ink limit at 85%?  It will result in different curves I'm 
sure, but if I set it to 100%, then the black boost will be meaningless if I understand the 
driver operation correctly.

One other thing I've noticed is that the Ink pattern page when printed at the 85% setting 
shows a slightly more pronounced 'grit' in some of the steps of most of the colors, but 
most importantly, in the black around the 50% to about 85% levels that is not apparent in 
the 100% printout.  The problem is that the L Black tops out at about 52.5% of Black  in the 
85% setting, and there is a bit of grit visible in steps higher than that in the Black ink.

Looking at the 100% printout, the L Black tops out at about 50% of the Black, but above 
that level, the Black shows much less pronounced grit in the levels, so this seems to be 
encouraging me to use the 100% setting for the default ink limit.

Any suggestions on the best course of action?
