Digital BW, The Print

Hi!  just wondering if anyone had any favorite methods for 
making digital positives for photogravure purposes on the Epson 
2200.  I have Dan BUrkholders book, and have been using 
Pictorico OHP.  I've used the curve provided on the CD from the 
Book, but since the Epson 2200 is much newer than the book i 
thouhgt i'd ask around .

Are there any better curves?  What is the best printing method?  
I've just been using  a workflow for Epson Photo Quality Glossy 
Film  (no color adjust) and 2880dpi, with photo black of course.

I work for a school and we are trying this out for use in a class.

any tips or info very very much appriciated!
