Gloss Back on CCNB

[kerri2424]

We were printing a conventional CMYK image with a UV coating and after 24hours, the non printed area, where the UV had coated the CCNB, had different gloss? Why did this happen? The UV is not supposed to absorb into the substrate, right?


Should I just run a varnish to seal the non-ink image areas first before UV coat?

If you UV coated over conventional ink, you need to run a primer AQ over it first. This may be why it glossed back.
