What resolution/pass? One in the lab at school lays down clear nicely. Matter of fact you can lay down so much in gloss mode that you pick up "environments". Learned "environments" from the Mimaki rep. Fancy term for whatever is floating in the air getting stuck in the clear.
It's spring break, but I have to be on campus at some point this week. I'll be able to check/ask about settings. Haven't run it enough to have things memorized.
