Description
Summary:One process has become a standard feature on many sheetfed presses, permitting fast turnaround of work by "sealing" the job to let the inks take their own time to dry without smudging or blocking. The other process, which continues to win new interest and practitioners, is a more complicated technique that is nonetheless earning a stand-out, beat-the-competition reputation. The former, of course, is aqueous coating; the latter is in-line hybrid LTV coating, in which sheets are printed with semiconventional inks and exposed to ultraviolet energy in one or more interdeck curing units, then overprinted with a UV-curable polymer type of coating that can add a high gloss, a matte finish, or even a metallic appearance. Printers and suppliers agree that it is UV's very distinctness - which allows a print buyer to achieve a unique printed piece and sets a printer apart from the competition - that makes the process so appealing. And despite the higher costs for materials, printers do reap the benefits of one-pass productivity and the quick processing of jobs.
