Printing production quality evaluation:  measurement of tone increase parameters  of prints by reflectometric method

Printing production quality evaluation possibility has been experimentally confirmed with the values of such characteristics of print tone increase (dot gain) as «flowing» zone width of ink to non-printing elements x and light reflectivity coefficient of non-printing elements central areas Rx . Based on the comparative analysis of measurement of tone increase parameters, the priority has been given to reflectometric method of x and Rx values determination.
