Michelman recently introduced its new DigiGuard UV curable OPV that cures and dries the moment it's exposed to ultraviolet light to form tough protective surfaces on paper and film printed on HP Indigo presses. The OPVs are approved by HP for use on their new UV Coater, are available in a variety of finishes, and have excellent adhesion to the HP Indigo Electroinks.
The UV Series offers several advantages over other varnish types. In addition to quick turn-around time because of its instantaneous curing, it is energy efficient, offers good protection against mechanical rubbing, can be used to produce extremely high gloss levels, and is solvent free. They are available in matte, satin and gloss finishes and can be used on a variety of papers and films. Some grades are also designed for superior performance during subsequent hot-foil stamping, imprinting, or gluing.
