Calculation of dot area with image analysis method

Abstract

Image analysis is a suitable method to calculate the basic print characteristic from print samples, because of the possibility of scanning geometrical and colour characteristic at the same time. This paper deals with the calculation of the dot segmentation of halftone dots from the print sample must be done. The paper describes an algorithm of dot area calculation based on the segmentation and presents the results obtained with processing one-colour and two-colour print samples. Finally the resuts of the image analysismethod and densitometric method are compared.
