The influence of printing substrate properties on color characterization in flexography according to the ISO specifications

Flexography is widely used in the packaging industry due to the fact that print can be adapted into various printing substrates, whose surface characteristics substantially affect the reproduction quality. Accordingly, this research comprises the comparison of the most important quality parameters of graphic reproduction in accordance with the ISO 12647-6 standard for three types of printing substrates: uncoated and coated paper and OPP film. The main goal is to examine the effect of the printing process in combination with various printing substrates on the color characteristics on the print. After the printing of a color-test form, the characterization of prints was carried out. The obtained results serve as the guidelines and recommendations for an easier and simpler control of reproduction. It has been concluded that the existing standard provides only basic recommendations. Accordingly, the characterization of the process should be adjusted to the customers' expectations.
