Abstract

Abstract Translated from German Eine Vorrichtung zur Abtastung von Druckplatten zwecks Voreinstellung der Farbzuführstellmittel einer Druckmaschine über optisch-elektrische Wandler (4). Den Wandlern (4) sind Meßkanäle (13b) mit reflexionsarmen Kammern (13a) vorgeschaltet, die die notwendige scharfe Abgrenzung von Teilflächen ermöglichen und eine feingerasterte Abtastung von Druckplatten verschiedener Art unter Praxisbedingungen sicherstellt. A device for scanning printing plates for the purpose of presetting the ink supply means of a printing press via optical-electrical converters (4). Measuring transducers (13b) with low-reflection chambers (13a) are connected upstream of the transducers (4), which enable the necessary sharp delimitation of partial areas and ensure fine-scanning of printing plates of various types under practical conditions.
