I did the manual head alinement, uni-D, with the pro inks, and Epson Ultra premium Luster(Letter size) and also Canson Baryta Photography(Roll, 24" with). The lines of LLK could not be detected due to the gloss optimizer, so I put “5” all. I printed the same images, but the results were same.
And then I did the manual head alinement with Epson Ultra premium Luster paper again. I thought the files themselves might have issues, so I created a flat gray image(K-89%/Gray/2.2/16bit) with Photoshop and printed it with both QTR and Epson driver in Print Tool.
Whenever I use QTR, I find the same banding issue, look like cross stripes to both horizontal and vertical direction, (Please take look at the attachment. The paper is Epson Ultra Premium Luster). And also I reinstall the curves with “Printer_Installers” and reset the printer, but the thing was same.
I am wondering what you think might cause this issue.
