Apparatus and method for screen printing radiation curable compositions
摘要:
An apparatus and method enables screen printing various articles such as glassware with a radiation curable composition using, for example, UV radiation and the like in pre-existing screen printing decorating equipment having a plurality of screen printing workstations. Particularly suitable compositions are those which are environmentally safe by virtue of being free of toxic heavy metals and volatile organic compounds. The applied inked image is at least partially cured at each screen printing workstation to form a skin on the surface of the transferred image of sufficient strength to support the next layer to be applied. The UV radiation may emanate opposing and underlying each of the screen printing workstations were brought thereto from a remotely positioned laser via a fiber optic bundle or light pipe.
