Sažetak
Modern packaging printing workflow has been nowadays directed to the flexography printing technique. It requires a usage of a number standardised processing procedures in order to create an attractive and consumer appealing packaging. With constantly increasing number of brands on the market, new qualitative requirements are present for flexography. The aim of this research was to evaluate two different types of modern flexographic workflow systems (LAMS and TIL technology). The hypothesis was that the standardised different workflows should give a product of similar technical and visual appearance quality. Measured parameters were: the formation and structure of the image elements on the printing plates, transfer of the printing ink to the printing substrate, dot gain on the printing substrate and visual evaluation of the imprints. Obtained results revealed the differences in formation of image elements on the printing plates as well as the difference in coverage values transfer from the printing plate to the printing substrate. Differences were detected in specific coverage areas (highlights, shadows), where the surface structures of the printing plates were significantly different. Addition analysis in form of visual evaluation of images, specific colours and tone gradients has been made and gave different results. They indicated that highlights and realistic colour on the imprint have been better reproduced by LAMS printing plate, despite the fact that better transition of tones through the whole tone range was measured on reproductions with TIL printing plate. This research has proved that technically correct printing plate and imprint can give a reproduction of lower visual appearance quality. Results have shown that reproduction of each packaging product should be considered individually in a closed reproduction workflow. Visual impression should be considered as a relevant parameter used in planning and production of packaging in order to satisfy the appealing and creative design requirements in packaging.
