Description

Retuschierverfahren für Rasternegative Die Erfindung bezieht sich auf die Retusche von Kollodiumrasternegativen. Autotypisch zerlegte Rasternegative haben den Fehler, daß in ihnen das Verhältnis der einzelnen Tonwerte zueinander dermaßen festgelegt ist, daß von irgendwelchen Variationen beim Kopieren keine Rede sein kann. Wohl kann man Kopien herstellen, die im ganzen etwas heller oder dunkler sind; dagegen ist es ausgeschlossen, Kopien gleich farbenrichtig anzufertigen.Retouching Methods for Screen Negatives The invention relates to on retouching collodion grid negatives. Raster negatives disassembled as is typical of a car have the fault that in them the relationship of the individual tonal values to one another it is determined to such an extent that there is no question of any variations in copying can be. You can certainly make copies that are on the whole a little lighter or darker are; however, it is not possible to make copies of the same color.

Das Retuscheverfahren für Rasternegative nach der Erfindung soll dem abhelfen. Dies besteht in folgendem: Das Rasternegativ, das so hergestellt wird, daß die Punkte einen Kein- und einen Halbschatten besitzen, wird nach dem Trocknen mit' Gelatine übergossen und mit lasierender Farbe, z. B. Neucoccin, übermalt, wodurch die Farbtöne auf dem Rasternegativ richtig gestellt werden, so daß die Kopie sauber und klar ohne Nebentöne steht und nur noch ganz kleine Nacharbeit auf der Platte erforderlich ist.The retouching method for raster negatives according to the invention is intended to remedy. This consists of the following: The raster negative, which is produced in this way, that the points have a no and a penumbra, becomes after drying with 'gelatin poured over and with translucent paint, z. B. Neucoccin, painted over, whereby the color tones on the halftone negative are set correctly so that the copy is clean and clearly without any secondary notes and only very little reworking on the record is required.
