Description

Verfahren zur Herstellung von Rastern. Bei der Herstellung von photographischen Kreuzrastern zur Aufnahme oder zum Kopieren muß man sich besonderer Einrichtungen bedienen, um die Linien gleichmäßig in das Glas zu gravieren. Es sind zwar auch Raster bekannt, bei welchen man durch Aufstäuben von geeigneten Stoffen auf eine Glasplatte einen sogenannten Korn- oder Staubraster erhält. Diese Raster sind aber nicht beliebig nach einer etwa vorher festgelegten Zeichnung herzustellen. Diese letzteren Raster waren zur Imitation von mit der Hand ausgeführter Lithographie ebensowenig zu gebrauchen wie die sogenannten Linierraster, bei welchen man stets das gleichmäßige Netz sieht.Process for the production of grids. In the manufacture of photographic Cross grids for recording or copying must be special facilities to engrave the lines evenly in the glass. There are also Known grid, in which you can by dusting suitable substances on a Glass plate receives a so-called grain or dust grid. But these grids are not to be produced at will according to a previously determined drawing. These the latter grids were for imitating hand-made lithography Just as little to use as the so-called line grids, with which one is always sees the uniform network.

Die vorliegende Erfindung besteht nun darin, auf mechanischem Wege einen Raster herzustellen, welcher die Technik der Handlithographie auf das genaueste nachahmt. Nach der Erfindung ist es möglich, ein beliebiges von der Hand hergestelltes Korn, eine Punktur oder ein Muster in bekannter Weise mittels Additionsapparats aneinanderzureihen, ohne daß Nähte sichtbar werden. Natürlich müssen die Muster für einen genauen Anschluß passend gearbeitet sein. Dieser so anennan(dergereihte Raster wird dann auf Glas geätzt, mittels einer Deckscheibe in bekannter Weise, wie dies sonst bei Rastern geschieht, überdeckt und kann nun in beliebigen Größen, auch kreisrund, an Stelle der bisherigen Kreuz-, Linien- oder Kornraster Verwendung finden. Man erhält bei V orschaltung derartiger Raster, insbesondere bei Farbaufnahme, eine die Handlithographie nachahmende Punktur.The present invention now consists in a mechanical way to produce a grid, which uses the technique of hand lithography to the greatest possible extent imitates. According to the invention it is possible to use any hand-made Grain, a point or a pattern in a known manner by means of an adder to be strung together without the seams becoming visible. Of course, the pattern must be suitably made for an exact connection. This so anennan (the lined up The grid is then etched onto glass, using a cover plate in a known manner, as otherwise happens with grids, covered and can now be made in any size, also circular, instead of the previous cross, line or grain grid use Find. If such a grid is connected in advance, especially with color recording, one obtains a puncture imitating hand lithography.
