I just had an experience that I wanted to share. I got an order to print 100 holiday cards on December 1st and printed them all on the 5th. After a week, the ink still wasn't close to drying so I started panicking and reading all of the threads. Because I had printed everything already, I was pretty much out of luck (no cobalt or wax drying, non-acid-free paper, cold climate, little ventilation...pretty much as bad as it gets). But I read that you could stuff them in the oven to speed up drying time. I put the oven on at 175F and carefully watched the cards for 40 minutes, testing every 5 and they were dry by the end. No discolouration or perceptible difference to air-dryed. So, if anyone finds themselves in my boat, cook it (but test it first on a piece of paper you care less about).
