QTR-Quadtone RIP

Hi Will,

Thanks for the help.  You are abolsutely right - I did a nozzle 
check and some cleaning and that seemed to solve the problem.  I 
must admit that I've never had a nozzle problem before (in 2 years 
of using the printer) which was why I was non-plussed.  Anyway - 
mystery solved and I can now get back to making the most of these 
inks!

Thanks again,

Tom
