Verfahren zur Herstellung von in Einzelelemente zerlegten photographischen Bildern.
EMI1.1
Benützungsart dieser Raster, indem ein solcher mit einer photographischen Schicht auf der rastrierten Seite verst-hen und entweder so zur Aufnahme benutzt wird. oder. indem die
Schicht nach ihrer Trocknung abgezogen wird und allein zur Aufnahme dient. Das fertige
Negativ dient zum üblichen Kopieren.
Die Zeichnung veranschaulicht im Schnitt vergrössert die Kopieranordnung eines mit dem
Raster verbundenen Negatives. Dabei stellt a die Rasterplatte, b das Negativ, c die hiermit in
Kontakt gebrachte Kopierschicht, z. B. eine Ohromgelatineschicht und d deren Unterlage. z. B. eine Metallplatte dar. e deutet die Kopierwirkung an. Unter den Raster-und Negativschicht-

Solche entickeltf Chromatgelatinekopipn können entweder galvanisch abgeformt werden oder sie liefern durch Selbstätzung ohne besondere Nachhilfe gute Druckformen.
An Stelle von Glasrastern können vorteilhaft Raster aus Zelluloid oder Gelatine z. B. durch
EMI1.3
oder es können auch geeignete Aufnahmeschichten, deren Oberfläche Reliefrasterform zeigt, z. B. als Films verwende werden.
Um den Kopierkontrast noch zu ändern. werden auch solche Raster benützt, bei welchen die hochstellenden Rasterteilchen bei möglichster Glasklarheit der Rastergrübchen mattiert oder gefärbt sind. Die Mattierung oder Färbung soll die Kopierlichtwirkung zwar verzögern

The negative is used for normal copying.
The drawing illustrates in section enlarged the copier arrangement with the
Grid connected negatives. Here a represents the grid plate, b the negative, c the in
Contact made copy layer, e.g. B. an Ohromgelatineschicht and d its base. z. B. a metal plate. E indicates the copying effect. Under the grid and negative layer

individual drawing elements and less copied elements, which lie in relief-like gradations child and lower and can be etched through according to their gradation. Such developed chromate gelatine copings can either be molded by electroplating or, by self-etching, produce good printing forms without any special tuition.
Instead of glass grids, grids made of celluloid or gelatin z. B. by

To change the copy contrast. Such screens are also used in which the raised screen particles are matted or colored with the greatest possible glass clarity of the screen pits. The matting or coloring is intended to delay the effect of copying light
