QTR-Quadtone RIP

Thanks Greg!  I did get it!  I created two simple curves that I can regulate with percentages for warmer or cooler whites.  I think I'm all set for now!  I don't have a desitometer or spectrophotometer, but I copied the curves delivered for my printer and just changed the ink that it draws from (photo black vs matte black).  Very nice!  Thanks again!

Since you only have one black ink in your printer, you don't have to worry about ink partitioning (this is required on printers which have multiple "light black" inks). The only concepts you need to master are setting an ink limit (which you can estimate just by looking at calibration pattern printout), and linearization, which can be done with just a scanner, if you have one, though I have never done it that way. You can also use a densitometer or a spectrophotometer if you have (or have access to) one of those.

The only curve selections that I have are "matte".  Do I have to create my own?  I hope not, I'm not sure I'm smart enough to do that...:(
