I guess he could ask one of those companies, but I thought there were a few printers on this board too.
I'll take a crack at it even though I know nothing. I think the image (at most) would be 3 colors, maybe even only 2. They'd probably print it using half-tones, would look like little dots in some parts of the image but with the texture there it wouldn't matter.
Also, if you convert it to vector and have any lines thinner than 2 pixels then those lines may not transfer well, or even be visible.
I'd love to see an authoritative answer here too.
