Description

Verfahren zur Herstellung von Sicherheitspapier. Es war seither nur möglich, in Papier Wasserzeichen nur in zwei, höchstens drei Schattierungen zu erzeugen. Das neue Verfahren ermöglicht jede beliebige Abtönung und macht so eine plastische Wirkung der gezeichneten Figuren besser geltend.Process for the production of security paper.

The new process enables any shade and thus makes a plastic one Better effect of the drawn figures.

Auf den abgegautschten Papierbogen wird zunächst mittels einer Form und Druckgebläse das Zeichen mit feinem vernickelten Eisenstaub aufgetragen. Die einzelnen Schattierungen werden durch stärkere oder schwächere Druckgebläse erzeugt, d. h. es wird entweder mehr oder weniger von dem in dem Gebläse befindlichen Eisenstaub auf das Papier gebracht. Ist das Zeichen in seiner plastischen Wirkung vollkommen, dann wird ein zweiter Bogen darüber gegautscht. Es entsteht ein, von oben betrachtet, wasserzeichenähnliches Zeichen auf dem Bogen. In der Durchsicht erscheint das Zeichen in plastischer Form. Das Verfahren läßt sich auch auf maschinellem Wege durchführen.A mold is used to first apply to the gummed sheet of paper and pressure blower applied the sign with fine nickel-plated iron dust. the individual shades are created by stronger or weaker pressure fans, d.

When viewed from above, the result is watermark-like mark on the sheet. The mark appears in the review in plastic form. The method can also be carried out by machine.
