Verfahren zur Herstellung bedruckter Bogen mit Lichteffekten

摘要

The motifs (4) deemed desirable are printed in a first step on one of the surfaces of a sheet of paper (2) by any conventional system. Thereafter, in a second step, there is applied to the printed surface a resin, thermoplastic lacquer or other transparent material (6) which impregnates the surface of said sheet (2), after which, in a third step, at least one area of the thus treated surface is engraved by pressure and heat to produce the said effects. Finally the continuous sheet (2) is cut into units (9). The resin (6') is polymerizable with ultraviolet rays and is polymerized at the same time as the engraving is effected.
