I have a new setup with an Epson 9800 running selenium p2 inks, printing with Hahnemuhle Photo Rag Pearl paper. There is microbanding present even though we are getting perfect nozzle checks before printing.
Before installing Piezography inks, we had perfect nozzle checks with Epson ink. We aligned the print head using the printer utility. Then we flushed the printer with Piezoflush and had perfect nozzle checks with Piezoflush. After that we installed the Piezography inks.
We are printing with Print Tool, 1440, Uni-D, roll and sheets. I did an manual Uni-D alignment check already and everything looked good (the best results per channel were on line #5 in all except 1 alignment pattern).
Is there another adjustment to make, perhaps with the media type or paper feed?
