Silkscreen Coating compatible with digital printing

[Labubre]

Hi,
Newcomer on this forum and starting small printing service activity.
I have an HP Indigo and i print succesfully on plastic.
But for one specific request, i had to print over metallic solvent inks printed in silkscreen.
My Indigo just did not stick over it !!!
Guess i have to coat my silver/gold layer to make in compliant for another pass on my Indigo S2000.

Does someone has experience on this specific configuration? A coating to advise me?
Thanks for support

You could try flood coating the sheet with Utopia DigiPrime before going through the indigo, no guarantees though that it will work with the screen printed metallic solvent, you might try calling Utopia first.

Thanks so much.
Thuis Digiprime range from Michelman's seems to be perfect.
Gonna try it soon.
