Description
Summary:The earliest adoptions occurred in structural bonding adhesives and UV digital inkjet for wide format sign printers and both single pass and wide format digital inkjet product decoration. [...]considering all the formulation, press, and LED capabilities now available; an increasing number of suppliers; growing interest and activity by both independent and multinational converters; and downward price pressure on equipment and formulations, it is a reasonable expectation that UV LED will represent nearly 50 percent of all new narrow web press purchases by 2023. [...]there is growing interest among central impression and stack press converters for single, dual, and fully equipped UV LED printers as well as single-station coating lines on wide web flexo and gravure presses. Guidelines on System Selection When evaluating or selecting a UV LED curing system for web applications, the following general guidelines should be considered. * Formulations and Final Cure Properties: The desired physical and aesthetic properties of the final cure as well as the intended product use should be specified and are instrumental in driving formulation chemistry and cure requirements.
