Sažetak
In this paper the differences of results obtained by three measuring systems for determining surface coverage value of the printing plates were presented. The aim of this research was the introduction of image analysis as an alternative method for the characterization of surface coverage and tone reproduction of printing plates. Results have shown that different measuring systems for image analysis (IC Plate, ImageJ and Stream motion) obtain a different result in coverage values calculation. IC Plate is automated device for capturing the printing plate’s area and automatically calculating coverage value, while ImageJ and Stream motion are programs supported by software which analyzes imported images that need to be captured by the microscope. Based on the results, one can say that ImageJ and Stream motion are more complex methods for coverage calculation, but they enable greater control of the imported images by means of manual adjustment.
