Description

Retuschierverfahren für Rasternegative Zusatz zum Patent 474346 In dem Patent 474 346 ist ein Retuschierverfahren für Rasternegative, die aus Rasterpunkten mit Kein- und Halbschatten bestehen, beschrieben, nach welchem die getrockneten Collodiumnegative mit Gelatine übergossen werden, worauf auf diese Gelafineschicht die Retusche mit lasierenden Farben, z. B. Neucoccin, aufgemalt wird.Retouching process for halftone negatives Addition to patent 474346 The patent 474346 describes a retouching process for halftone negatives, which consist of halftone dots with no and penumbra, after which the dried collodion negatives are poured with gelatine, after which the retouching with translucent colors on this gelatin layer, z. B. Neucoccin, is painted on.

Nun wurde gefunden, daß auch Trockenplatten nach diesem Verfahren retuschiert werden können. Es wird in bekannter Weise einfach auf die Gelatineschicht der Platte mehr oder weniger Lasurfarbe aufgetragen, um die gewünschte Veränderung der Größe der Rasterpunkte beim Kopieren zu erreichen.It has now been found that drying plates can also be produced using this method can be retouched. It is simply applied to the gelatin layer in a known manner the panel applied more or less glaze paint to make the desired change to achieve the size of the grid points when copying.
