Description
Verfahren zur Herstellung von Gelatinedruckformen. Zusatz zum Patent 347748. Gegenstand der Erfindung ist eine Abänderung des Verfahrens nach Patent 347748; sie besteht darin, da13 an Stelle ider dort vorgesehenen Quellung .der Gelatine in kaltem Wasser nach der Belichtung eine Halbauswaschung der ,unbelichteten Gelatineteile in warmem Wasser von einer Temperatur, durch die die Gelatine sich auflöst, oder auch eine mechanische Überreibung der Gelatine mit einem mit lauwarmem Wasser -getränkten Bausch aus Watte oder ähnlichem Stoffe, durch .die die Gelatine zur Hälfte beseitigt wird, erfolgt. Die Gelatineplatte wird nach dieser Behandlung der Einwirkung von trockener Hitze ausgesetzt.Process for the production of gelatin printing plates. Addition to the patent 347748. The subject of the invention is a modification of the method according to the patent 347748; it consists in the fact that the gelatine instead of the swelling provided there After exposure, the unexposed gelatin parts are half-washed in cold water in warm water at a temperature that will dissolve the gelatin, or also a mechanical overriding of the gelatine with one soaked in lukewarm water A pad of cotton wool or similar material that removes half of the gelatin is done. After this treatment, the gelatin plate is exposed to exposed to dry heat.
Durch diese Halbauswaschung der Gelatine werden zunächst die belichteten Teile der Gelatine teilweise freigelegt und dadurch einerseits eine O,uellung der unbelichteten Gelatine, anderseits eine Vertiefung der Zwischenräume bewirkt.As a result of this half-washing of the gelatin, the exposed ones are initially exposed Parts of the gelatin partially exposed and thus on the one hand an o, ulling of the unexposed gelatin, on the other hand causes a deepening of the spaces.
Durch die darauffolgende trockene Hitze werden sodann die gequollenen ,und die vom Lichte weniger betroffenen Teile zum Schrumpfen gebracht.The resulting dry heat then causes the swollen , and the parts less affected by the light shrink.
Dieses Verfahren trägt zur Tieferlegung des Punktes zwecks Erzielung einer guten Druckwirkung bei.This procedure helps lower the point in order to achieve it a good printing effect.
