QTR-Quadtone RIP

Roy, Tom,

I must say I have also a lot of sympathy for Tom's suggestion. The 
best of both worlds could (at least in theory) be one image file 
containing 3 alpha channels, 3 alpha channels controlling the 
contribution of each of 3 curves as a function of density.  Perhaps 
that is what IJC/OPM is doing?? Would give a HOST of possiblities 
(although some could become quite complex to edit). Like Tom I'm on 
PC. But I understand the two-platform issue. Too bad indeed.
