QTR-Quadtone RIP

Mike,

Very interesting.

I was not aware of the "right click" and I was able to view the curve.  I also opened the QUAD file in Excel and this showed two columns and 2058 rows.  This profile was for a R800 / R1800 ink profile and four of the "active" inks there were values in that section and in the other 2 inks section all zeros.

Is there some write-up or info sheet somewhere on how to manipulate the numbers to change the ink curves in these files?

Thanks, Terry
