Digital BW, The Print

Hi Steve,

I'm not sure what more I can add, but the weird patterns you see are
the way the microweave works.  It is strange and the exact gray value
being printed does affect it showing during the lay down.  Part of the
reason using QTR shows this more than the Epson driver is that fewer
number of inks are being used.  In the cases I've seen when all the
passes are finished the effect is completely covered up.  But it sounds
like you are left with some kind of scratch-like banding.

Have you always had the problem?  Changed inks recently?  Is it
mage dependent?  Slightly tonal changes or just adding a small amount
of noise may help.

Roy
