New Screen Coating Catalog

Traditionally screen coatings have been the more economical alternative to lamination. Today printers are using screen coatings to create a diverse range of printed pieces, in particular specialty pieces that are designed to stand out and catch your eye.

Kustom Group has created the Screen Catalog to include many of these specialty screen coatings, including color shift, glitter, and tactile (raised, rubber feel, sandy feel and soft touch) as well as gloss, satin and matte options for use over a variety of inks and stocks.

LED Curable Coatings and Litho OPV’s

With LED curing system installations and retrofits on the rise, Kustom Group recognizes the need for a more diverse portfolio of LED curable coatings and overprints. With that in mind, we introduce our latest catalog of LED curable coatings and overprints divided into two categories based on press configuration we title “for Offset Gap” and “for Flexo Gap”. The idea of one particular LED coating curing across a wide variety of press configuration is no longer technically viable.

 

The biggest challenge to LED curing continues to be surface cure which is drastically impacted by the gap between the array (lamp) and the substrate. The location of the array is dictated by the equipment it is attached to and how the standard printing processes operate. In offset printing, the location of the array is impacted by the grippers used to move the individual sheets through the press, while in flexo there isn’t the same issue when running a web. The gap between the array and the substrate is very different: in offset applications it is 5.0 – 6.5 centimeters, while in flexo applications it is 3.0 – 5.0 millimeters – a factor of 10+.

 

Kustom has determined that no one LED coating can work well for both offset and flexo applications. These differences create different curing parameters and require different products. A coating formulated for the flexo gap will likely never fully cure if applied at offset gaps, while the risk of using a coating for the offset gap on the flexo gap process may result in over yellowing, limited press stability and brittleness of the cured film. Kustom Group’s latest developments, outlined in the tables below, are a direct response to the need for better choices for the given process. Our “for Flexo Gap” coatings are suitable for close proximity arrays, and our “for Offset Gap” coatings and overprints are intended for the greater offset gap employing eight (8) Watt or higher bulbs.
