the flatbed conversion will never be a problem, even if the printer curls
the paper around 5 rollers and folds it afterwards to fit a emvelope.

the problem is the ink.
the chances are high you have done the conversion for nothing (welcome to
the club).

uv curable means the ink you inkjet on the copper solidifies when exposed
to UV.
it is some plastic polimerisation process.

UV sensitive means the ink changes it's properties, so that it can be
whashed
off by developer where exposed. It is a solvent based ink, which must dry
before
you can expose it. the solvent may even attack plastic.

I'm only saying you can't use any of the UV functionailty in resist laquer.
you could use standard laquer all the same.

I'm not sure about plastic compatibility.

good luck
