What about the white? There's no white metallic I've seen; maybe a crystalina? Can you show them how it would look with traditional inks, white, 2 or 3 grays, a tiny bit of black, like printing chrome wheels? You might spend the time on the metallics only to find it looks, well, not so good...SteveArtelf had some pretty good chrome effects, maybe he'll chime in?
I had a thought, how about a silver shimmer for one gray, and liquid silver (wilflex I think) for a different metallic? They have different finishes which might add to the effect, maybe even flash them and overprint on a shimmer or liquid silver with, well, I don't really know yet, these things come in spaced out pieces sometimes...SteveAnyway, just hit 11.5 hours, so I'm going home to eat, relax, and do some more art for stuff we need for the long weekend...
Here's the deal Pierre. Liquid silver and many metallics and shimmer are indeed tintable. The best way to tint is with............anyone?Also consider the clear foil I would add $1.00 for either could go down to .75Ok I'll spare the suspense, you tint with process inks, especially process black for blk/wht tonal work. Try 45 LPI
