Re: Having problems with Paul Roarks curve settings

2003-11-09 by markroth61

I also have an 1160, and you may find very satisfactory results not 
using those curves, but instead creating a transfer function curve 
(search here will yield the details). It makes all the difference. 
The trick is an 11 step wedge to determine your tonal values.

I believe Paul's work is wonderful, but each specific printer seems 
to be different in how it reacts, so there is no flat answer.

I'm getting terrific results using this method.
Best,
Mark R.
