ANALYSIS OF HALFTONE DOTS DEFORMATION IN THE PROCESS OF PACKAGING AND EXPLOITATION OF CARDBOARD PACKAGE

The aim of this study is to determine the possibility of changes in the halftone dot due to the exploitation of printed materials. The changes can happen due to stretching of the material and produce problems after such inaccuracy, in the preparation of printed package, filling package, transport and so on. Also, in the exploitation of the package unit, the base material can be exposed to some additional mechanical loads (like cardboard bags) where it is necessary to determine whether there is a change in the staining material.For analyzing the deformation of halftone dot on the printed package the packaging operation was performed by analyzing the material in process of production, after the printing process in the course of tension acting on printed material. This analysis gave an insight into the behavior of halftone dots in the course of exploitation and their level of physical activity during the tension force on the material on which they are located.
