Printing press comprising a magnetic orientation unit and a movable drying/curing unit

Abstract

There is described a printing press () comprising a printing group () adapted to apply on a substrate at least one ink or varnish vehicle containing magnetic or magnetisable flakes and at least one magnetic orientation unit () located downstream of the printing group () along a path of the substrate, which magnetic orientation unit () includes at least one magnetic-field-inducing device () adapted to orient the magnetic or magnetisable flakes contained in the ink or varnish vehicle applied on the substrate to induce an optically-variable effect in the ink or varnish vehicle. The printing press () further comprises a drying/curing unit () located along the path of the substrate and cooperating with the magnetic orientation unit (), which drying/curing unit () is adapted to dry or cure the ink or varnish vehicle applied on the substrate following orientation of the magnetic or magnetisable flakes. The drying/curing unit () is mounted on a movable supporting structure () that is adapted to move the drying/curing unit () between a working position (WP), where the drying/curing unit () is cooperating with the magnetic orientation unit () and which is located proximate to the path of the substrate next to the magnetic orientation unit (), and a retracted position (RP), where the drying/curing unit () is retracted away from the magnetic orientation unit () and from the path of the substrate.
