Re: Adjusting Curves after Linearization

2009-02-05 by robert49brake

An addendum:  With Eboni it is also very easy to apply to much ink which can have two negatives.  One is 
actually decreased D-Max and two is a very wonky bottom of the shadows.  Paul Roark has a good tutorial 
here:

that addresses that issue.  Paul uses a different approach with ICCs instead of QTR curves but the principles 
are the same.  There is also a copy of the 90-100 stepwedge.  As a general point If I get any decent 
separation between the 95 and 100 points I don't try to go any further with the matte papers and Eboni.
