QTR-Quadtone RIP

Dear QTR Group:

I produce kiln fired photoceramics by printing a home-brewed digital 
fluid onto water slide decal paper, transferring the decal to 
porcelain, tile, glass or porcelanized steel and firing at 1100 to 
1300 degrees F to produce a really long lasting image.  I am 
printing with an Epson 1280 using only one cartridge in the black 
position.

After watching this group, and finding a two channel write-up by C. 
Jones, I would like to try to better control my results as there is 
tremendous dot gain both at the printing and the firing stage.  My 
trials with the only two curve program in 1280 set up is not 
encouraging. Another reason to learn to work with one or two 
cartridge positions is to access other operational channels when I 
block up the black position. Perhaps a two channel printing may give 
more low contrast detail in the lighter portions of an image.

I have failed to master creation of new usable curves using QTR as 
my experience in digital reprogramming is less than zero. Is there a 
class or mentor that can get me started in QTR so I may improve my 
photoceramic images?

Thanks for any help,
Harry L. Burnett, Jr.
