QTR-Quadtone RIP

2200, MIS UT7, Kirkland...

Using QTR I get micro-banding-like texture on Kirkland's very high
gloss in deep blacks, but not with Black Only. I'm sure its texture
because it vanishes with lacquer spray. 

Thoughts?

Hi.
Is it possible you might be very near the "too much ink" point? The
normal driver is probably limiting the ink even in Black only, while
you can pump a bunch with QTR. Could excess ink just be laying on top
creating the texture in a sort of thick and thin drying pattern that
affects the gloss? 
I had something similar to this happen when I tried to use up a set of
Quads I had kept around too long. The full black had begun to thicken
and dryed nearly instantly on hitting the paper. It made the dark
blacks look pretty weird even on a 3000 with it's large dot size.
I also saw something like it when I tried to make a QTR curve to use a
VM mix on Kirkland, for strictly occasional need. Before I worked it
out I was flooding the paper consistently and as I approached a viable
point of use the reticulation was evident. Yes, I know, matt ink=no no
on glossy. I did it anyway and it worked. I wouldn't use it for
anything beyond emergency copy work in B&W but it worked fine as long
as I could live with only about d'log 2.1-2.2 on the Kirkland.

Regards
Duane
