UC500 COATING AND PRIMING UNIT

The UC500 coating line is a universal coating/priming unit. It comes as an inline or offline version. Inline versions support all major digital presses. GM delivers the UC500 in both left- right and right-left run direction. Coatings are applied with a flexo graphic station and can be both UV and water based. The UC500 can be equipped with partial varnish, lamination, super gloss and other coating options. For priming synthetics a Corona system is needed. Water based coatings will need a closed chamber option in most cases. The UC500 can be delivered in a “full duplex version” that applies coatings to both sides of the web. The standard 4x1.6 meter UC500 has a more compact sister; The ultra compact UC500L. This light version measures only 2x1.6 meters.

The converting line consists of a UV varnish, lamination/supergloss with length slitting.
Operation can be both inline with a dancer or offline (optional unwind module).
Typical applications are banners, folders, post cards and roll-to-roll printed labels (not die cut).
The line is operated by a touch display and available for web widths of 330mm (~13.0”) or 515mm (~20.3”). The machine can be supplied with rotating length slitting.
