I printed out a couple Hinterland Cliff tops to put onto the foamcore I've been cutting, and darn it if the printouts didn't seem way more yellow than I'd like. They should be a really rich, deep green. I printed out a test page from the printer (you know - the one where I just replaced the print head?) and GRRR the cyan is streaking again!
I am thinking there was something seriously wrong with the batch of cyan I got. I'll be calling the company that sold the ink tomorrow to see what's up.
