Study of the quality of printed images on cardboard packaging

The intensive development of the packaging industry puts forward increased requirements for the design of packaging, the quality of their decoration with printing tech nologies. There are increased requirements for packaging materials, in particular their environmental friendliness. Therefore, many manufacturers prefer a material such as cardboard, which is completely recyclable. The article is devoted to the study of the gravure printing quality on cardboard imprints. An analysis of influencing factors on the quality of densitometric and colorimetric indicators of imprints is carried out. The surface structure of imprints is studied. On the basis of experimental studies, diagrams of the optical density of printed images on cardboard with different grammage and structure are constructed. Colorimetric studies of imprints are presented. The influence of the cardboard structure and roughness on the quality indicators of gravure imprints are confirmed.
