    We purchased our 1st UV press a year ago and we are getting more cracking on the spine of covers and brochures when folding. Definitely more than we get from conventional. Also seems to be worse if it gets off line UV coated. Grain direction is correct and scoring before folding barely helps.
    Is this from over curing?
