Hi, I've been using Conecolor ink in my Epson 4800 for a couple of years, but recently I've sometimes noticed that full black areas of a print have a strange quality. It's hard to describe, but kind of milky and not a clean black. Now just recently, I made a print and i could actually smudge my finger on it. It was almost as though I printed on the back of RC paper.
Any idea of what's going on here?
