Re: Dmax Question

2007-11-30 by Louis Dina

Howard,

Good point.  I will try both.  I am guessing that increasing the 
overlap will hurt rather than help, but you never know until you try 
it.  The black only curve should make it clear whether the light inks 
are the culprit or not.  If I get the same Dmax in a BO profile as I 
do when I print the inkseparation target, that would seem to confirm 
it.  If not, then something else is at play here.

Regards, Lou
