Abstract

A wide range of consumables and equipment, high requirements for the quality of printed products, the use of triad and mixed inks in flexographic printing, lead to the need to carry out thorough incoming control of new raw materials and conduct test printing, obtain a reference print before starting the run. In this regard, the research of color formation in the "printing form-imprint" system when using new consumables for flexographic printing in the technological process is always an urgent task. Prints from a real order were selected for the study. Profiles printed on various non-sticky printed materials and samples of flexible packaging were used as test fragments. Visually and instrumentally, the stability of color reproduction during flexographic printing of flexible packaging and labels was investigated. The dependence of the saturation of CMYK and Pantone colors on the print on the printed materials used and the presence of a white substrate was determined. The pre-printing of non-woven material with white ink affects the subsequent color saturation indicators on the print and improves the color characteristics.
