Weeeeeeeell it's really just like any regular printing really. I mean, you ever print on photo paper at a high enough res to not suck? Well that's about it
Things to note
-not all decal paper's the same so get the one that works on your tech
-Paper comes in clear and white backing. I've never have luck with white unless it's simple geometries
-At least 300dpi, more if you can do it
-trial on regular paper first. When things are "right" on sizes and quality, then go for the real thing
-White's a bitach unless you're rich and have the correct printer like some okidata 7xx series. It aint cheap to print either but might be worth asking around at a print shop somewhere close? Perhaps there's finally a budget printer that does white now so worth checking on.
