(Using Epson 7890, K7 Neutral Inkset, Hahnemuhle Museum Etching)
I’ve refilled (or topped off) some cartridges with some new bottles of ink with the same SKU as the the ink that I had already been using, and now my prints are coming out more dense and have a horrible color shift away from neutral to Blue/cyan. I’m actually shocked at the difference. I’m starting a print edition (which could contain ultimately around 1,000 16x20" prints) and wondering if this is a mistake… What’s going on?
Even the ink in the bottle (#7 N) looks like it has stained the plastic a blue/cyan color.
Also, I’ve been under the assumption that these inks are made with all carbon pigments. Am I wrong? What causes the blue/cyan?
Thanks in advance for the help!
