QTR-Quadtone RIP

When you state "vertical banding" I presume you mean banding in the
direction of paper motion rather than print head motion. If that's the case,
and it's in the high density areas, you could consider the possibility of
pizza wheel tracks. I had a similar problem on my 2200 that only seemed to
occur when I used QTR. I think it had to do with the amount of Ink I was
able to get QTR to put on the paper in the dense areas of the image.

I got rid of the tracks by lifting the Pizza wheels off the paper. Here's a
reference for the 2200. Perhaps there's something similar you can do with
the 1290.
