Any success w/ 4/C process on white ink w/ WT7900 metallic?

[speekn]

I know that Epson doesn't claim that 4/C process ( on white ink ) will be accurate on their metallic substrate, but we need to get as close as possible. Any hints or tips would be greatly appreciated. Manual curves for individual jobs is not an option. Thanks in advance! Also curious how many WT7900's are out there...?

I would create an ICC profile for the colour on white base printed on metallic film.

Do you also need to simulate spot inks on white on the silver, or just four colour?

What RIP are you using? Does it allow you to lay down more white ink density or are you at max. anyway (or perhaps this is not a contributing factor)? If you print white down with no other colour on top, how well does it bond to the silver and how dense is it?
