Description

Verfahren zur photomechanischen Herstellung von Druckformen-Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zum Skelettypieren belichteter Halogensi.lbierschichten und Schichten mit Silberbildern hach Patent 665 893. Process for the photomechanical production of printing forms - The invention relates to a further development of the process for skeleton typing of exposed halogensi.lbeerschichten and layers with silver images according to patent 665 893.

Es hat sich gezeigt, daß .es leichter gelingt, eine tiefere Schwärze der Skelettbestandteile, dementsprechend eine größere Klarheit des Skeletthintergrundes au erlangen, wenn nur die Oberfläche der Schicht entwickelt wird, d. h. wenn die Entwicklung auf eine möglichst kurze Zeit beschränkt wird, indem beispielsweise ein besonders stark angesetzter, gegebenenfalls warmer Schnellentwickler benutzt wird. Es ist damit der weitere Vorteil verhunden, daß derartige Platten harmonischer wirken und auch dünn genug, d. h. lichtdurchlässig genug ausfallen, um eine gute Belichtung der zu ätzenden Metallplatte zu erreichen.,It has been shown that it is easier to achieve a deeper blackness the skeletal components, accordingly a greater clarity of the skeletal background au attain if only the surface of the layer is developed, i.e. H. if the Development is limited to the shortest possible time, for example by a particularly strong, possibly warm, rapid developer is used will. This avoids the further advantage that such plates are more harmonious act and also thin enough, d. H. translucent enough to be good To achieve exposure of the metal plate to be etched.,
