Abstract

Ein Druckbogen (3) der in einer beliebigen Lage auf einem Digitalisierungstableau (1) liegt, wird gezeigt. Der Druckbogen (3) mit einem Griffel (2) an Meßpunkten (2.1, 2.2 ggf. 2.3) zur Lageerkennung abgetastet. Danach werden die Farbmeßfelder (14 - 14.3), die je nach Druckauftrag in beliebigen Bereichen zwischen Druckbögen angeordnet sein können, einmalig ebenfalls mit dem Griffel (2) abgetastet. Mittels der vom Griffel (2) gespeicherten Lagekoordinaten­ werte kann beliebig oft ein Densitometer (8) automatisch angefahren werden. A printed sheet (3) in any position on a Digitization table (1) is shown. The printed sheet (3) with a stylus (2) at measuring points (2.1, 2.2 if necessary 2.3) scanned for position detection. After that the color measurement fields (14 - 14.3), which, depending on the print job any areas between printed sheets can also be scanned once with the stylus (2). Using the position coordinates stored by the stylus (2) a densitometer (8) can automatically take any number of values be approached.
