QTR-Quadtone RIP

Paul,

Yes, I am pleased with those results... but soon after I submitted my samples I wished I had not used the spray, in order to get results more comparable to other tests in the database, most of which do not use a spray. At the time I was under the impression the spray would help improve the test results. Moreover, a while back you mentioned the spray lessened the DMax. 

I guess I could submit some test patterns without the spray... but it would take a while to reach 100 Megalux hours again!

Paul
