Zeller+Gmelin has added new adhesive systems for the finishing process by means of cold foil transfer on sheet fed and web offset printing presses. The adhesives from the Uvalux series, with the product codes LED U0850 and LED U0851, are both designed for LED UV technology. The company now also offers LED UV curing adhesives.

The two new products are an important complement to the wide range offered by the printing ink supplier. Altogether, the Uvalux series is a complete program that provides the appropriate product, including low-migration variants, for various applications in UV offset and letterpress printing on narrow web printing presses, as well as in UV sheet-fed offset printing. In addition, the entire program includes the two series Euralux and Uvaflex, with which Zeller+Gmelin also serves the segments of conventional sheet-fed offset printing, as well as UV flexographic printing.

LED UV users are able to utilize metal effects on paper and cardboard both in packaging printing (non-food) and commercial printing. For the curing of the highly reactive cold foil adhesives, LED UV systems in the wavelength ranges of 385 and 395 nm can be used. In processing, the adhesives safeguard a good adhesion to the film and the substrate. They feature a sharp edge definition in printing and are very stable in the ink duct, even with high-volume print runs. The difference between the two systems is the coloring, which supports an exact positioning and easier control of the applied quantity. Uvalux LED U0850 is a yellow-colored adhesive intended for the use on gold foils and Uvalux LED U0851 is a gray-colored system for silver foils.

Currently, LED UV systems are increasingly moving into the market as an alternative to conventional UV curing. They offer a number of economic and environmental benefits. These include low energy consumption and a long service life, as well as the elimination of warm-up time and waiting time when the lamps are switched on or off.
