I've had a chance to make some prints on aluminum, and I find them rather "muted". If I lay my metal print next to the same image on paper it looks a bit "dull". I'm assuming this has to do with the lack of a bright white base, which the paper has. When I compare soft proofs, aluminum to paper, I see the same difference on my screen. Is this consistent with what the rest of you see?
I picked up some nice aluminum sheets from an engraver, the kind coated for dye sublimation with the protective cover. I coated the metal (2 coats) with Golden Digital Grounds for Non-Porous Surfaces. There was a day of dry time between each coat. I used the Booksmart profile for my 3800, which has Epson inks. However, I have yet to spray a protective coating on the print.
I will say that under a bright light they can look pretty cool. One image in particular, a thistle with purple at the centre surrounded by green pointy leaves (leaves have a purple border), looks almost 3D under a light positioned at the correct angle. The green leaves literally glow and pop out. However, under normal light it doesn't look particularly spectacular.
I will also say that the b/w print I tried looks the best to me so far, at least in general terms.
