QTR-Quadtone RIP

I wonder if the odd "overspray" is from a poor down-sampling algorithm.  If
the ABW mode test file is re-sized to 720 in Photoshop does it also exhibit
this characteristic?  The overspray looks like what I'd expect if there were
junk stuck to the head that was deflecting a nozzle.  

 

I noted a comment in another thread that a new printer banded with QTR but
not the Epson driver when the image was too close to the top or bottom of
the page.  This appears to usually be caused by paper transport problems.
The comment made me wonder if Epson has a dither pattern that is made to
hide this type of defect - perhaps at the cost of some sharpness, however.
