Need Help Printing register bars on black media

[David Wilson]

We do a lot of printing on reflective black media, and I was told that Onyx can print bars containing cut register marks on black media using its silver or white spot color. Does anybody have any guidance as to how to set up this workflow? I can't find anything in the Onyx documentation. We are using the current version of Onyx on an Epson S80600L.

I don't know how to make that work in Onyx, but I'd love to see what the prints come out like on a black reflective if you'd care to share a photo.
