QTR-Quadtone RIP

I'm having a slightly visible horizontal banding ad the first and last
cm of the print. I have a Epson R265 with QTR 2.5.2, BO with QTR.
I tried unidirectional and bidirectional.
I'm using 2880dpi. Curve is designed by myself.

Paper is PGPP and UPGPP and Premium Semigloss.

I read old posts, but I can't find a solution.

Any hint?

Thanks in advance.

You don't say how much white space you are leaving for print margins,  
but it would probably help to have at least 1 to 2 inch borders.   
Trying to print too close to the paper edges will cause the type of  
banding you are seeing.

I've run into this for years with different printers and workflows. I think
it's a paper transport problem.  My old 3000 had it, and I got rid of it by
having more margin at the top and bottom of the image so that the printer
had more paper to grab onto.  My relatively new 1800 also shows the problem,
and again the cure is to be sure there are ample top and bottom margins.  If
both sets of rollers -- before and after the head -- are engaged, I suspect
the paper transport is more accurtate. Thick papers are usually more prone
to it than thin papers.  QTR is probably not more prone to it than the Epson
driver.

Thanks Carl, that what I did, and it worked. But leaving 1.5 cm at
both end of an A4 sheet, I don't like too much, I hoped there was a
better solution... Bad luck.

Thanks again, to Paul as well.
