QTR-Quadtone RIP

Cheers Joost

I've looked at your curves and understand how you put them together, 
and I must say they were a great help to me, unfortunately I'm 
trying my 1290s first so I couldn't actually run off any prints, 
which was frustrating for me. I also have decided to go with the 
2880 dpi approach.

I did try something new last night, I produced a simple Lab a axis 
toner curve on its own, using the Load Curve option in the curve 
creation tool and set the figures of 0,0 and 100,100 with the 
default ink limit of 65% in my case ( this basically gave an ink 
seperation 21 step wedge) which I then linearised. I then produced a 
print using a blend of 50% of my neutral curve and 50% of the above 
Lab a toner curve (to just pull the neutral curve along the Lab a 
axis - just like Paul said it would) to produce the kind of toned 
print I've been hoping for since I closed down my darkroom, I'm very 
satisfied indeed.

All thanks of course to Paul Roark and the QTR team, take a bow 
gentlemen,

Jamie

Like you I've been playing around with the Ut3D inksets. A few weeks 
ago I uploaded some curves (for my 2100) in the file section. I 
don't claim their perfect (actually I'm redoing som of the work now 
to change them into 2880 dpi), but perhaps they can be a source of 
inspiration. Any comment is also appreciated.
