Not all inks behave the same. Why would some inks behave differently? Well, really, it boils down to chemistry. The source pigments that are the basis for inks can have unique behaviors. Some of them don't dry fast. Some of them don't stick well to previous ink or paper underneath. Some of them are prone to scuffing, and some of them don't give very heavy coverage. So here are some examples of common problem inks. Fluorescent inks, for example, use something called fugitive pigments. And what fugitive means is those pigments are subject to fading when they're exposed to sunlight or any UV light source. And high heat can cause fading as well. So that might mean that if you're creating an outdoor piece, maybe it's not a good idea to fluorescent inks. And sometimes it can take two passes to get full coverage, to get the strength of color that you want. So if that means that you have to use two units on the press, it means you're using more ink.
