Quantitative evaluation of quality of flexographic imprints by means of fuzzy logic

Abstract

The article is devoted to the quantitative evaluation of quality of flexographic prints on polymer films. Based on the conducted analysis, we have set the key parameters of quality imprints, such as color difference, reproduction of a minimum raster dot, ink adhesion to the substrate, image positioning. In accordance with the known terms, the fuzzy knowledge base of parameters of imprints quality with the performance of the condition “if-then” has been formed. Based on this knowledge base, fuzzy logic equations of calculation of imprints quality options have been built and defuzzification by the method “center of gravity” has allowed to get the quantitative parameter of imprints quality that is the result of keeping to the relevant modes of flexographic printing process.
