Hi Jeff,

Thanks for your input.  The dots I have seen were not on the
stepwedges/ramps but on different prints.  When I was first starting
I printed using both the Piezo driver and Epson driver/Randall curve
and in a few it seemed in some of the mid-tone transition areas the
Piezo was smoother.  I'll dig up a couple examples of prints where I
saw this most evident and scan them as well.  I'll let you know.

Oh, and yes, for now all I've been printing on is EAM.

Best regards,
 Richard
