Grey balance metamerism of the Digital Printing Techniques Dependent on the Patch Size Observation

The research of the metamerism was performed by measuring the integral colour density of the grey patch on different printing substrates, printed by different techniques. The print measurements were performed at A , C, D50, D65, F2, F7 and F11 illumination sources and were performed under 20 and 100 wiewing angles. The measuring results show the appearance of metamerism between the grey balance patches and the screen value of black colour. The prints were obtained by printing on the smooth and on the rough printing materials for fine art printing. They were made on conventional offset printing machine, on digital printing machine with the transferrable electrostatic belt which uses powder toner and by the digital printing technique with the liquid ink.
