QTR-Quadtone RIP

Hi All,

I love qtr and was using it with my epson 2200 without a hitch.  Now I
have the R2400 printer and need some help.  

I am getting a very small width banding pattern.  I have tried
everything I can think of .... using different dithering patterns,
paper, inks,etc.  I am not getting any banding pattern at all using
the epson driver in the advanced black and white mode... smooth as
silk. I am using the curves that came in the recent release 2.3.1

I would love to be able to use the QTR software because of the
incredible control it offers.

I have combed this forum in search for answers... perhaps a math issue
because of the extra nozzles and or difficulty in changing the dot
size? Roy.... can you help?

Is anyone else printing successfully on Kirkland glossy using QTR, the
R2400, and epson ultrachrome inks?

Thank you again for your time and for a wonderful software and forum,

Bill
