Hi Sandy,
What I'm seeing is top to bottom fine horizontal banding but only when using thinner glossy papers. When I use Canson Platine, I don't see the banding, or perhaps it’s obscured by the paper’s texture. (So this limits my paper choice, obviously).
But what I'm *hearing* is the printer speeding back and forth even at unidirectional / 2880, which is what I'm curious about. When I print via the Epson driver, the printer slows to a crawl and there’s no banding on the thinner glossy papers.
By the way, I'm printing using a modified version of UT-14 inks, using all 8 channels for maximum smoothness. I'm very surprised to see any banding, even on the cheaper glossy paper.
