After reviewing your order history, I see you recently purchased a set of ConeColor Pro ink bottles and refillable carts for your Epson 3880. You should be able to get great results with ConeColor inks on Luster paper, as you did with Epson inks. Are you printing from Mac or Windows? What operating system version? What Media Type setting are you selecting in the print driver? Is your printer in MK or PK mode? Are all eight channels fully printing on your nozzle check?
Please let me know, thanks~ Dana
