Re: [Digital BW] IJC/OPM - Creating Curves from scratch

2005-01-05 by Joe Berndt

Hello John,

The way you mentioned , by using the starting curves is the best way to
start, In not familiar with the VTBlax inks so they might have a heavy
density.
Once you select the starter ink shapes,. E.g.  Black, Dark Grey, Mid Grey,
and Light grey,.  Your next step is to print a tweaked ink target.
So this sounds like where you are..  If this target is too dark. The next
step is to reduce the scale of these inks.

You will notice in the ink shape editor, that when you edit one of these
inks.  There will be a vertical slider to the right of the editing window,
this slider controls the scale of each ink ( how much of the ink it uses).
So as you will see by moving the slider down, the ink shape you built will
scale up and down as well.

So the next step would be to simple scale down the Dark Grey and Mid grey
10-25% I¹d leave the Black and the light grey as is for now.  After a  one
or two adjustments you should be ready for Linearization.

What you are looking for prior to Linearization  is a good separation of the
steps of the target, Linearization will do the rest.

Joe
