Analysis of the Quality of Packaging Prints Obtained with Four Different Black Inks on Metallised Substrates

Packaging has become an integral part of our everyday lives. It is used for a wide range of products. Printing on
packaging provides information about the products themselves, the manufacturer and other important information
required by regulations. Although its main purpose is to protect goods from damage, contamination and external
influences during storage and transport, packaging also serves as an effective means of communication between the
product and the consumer. The appearance of the packaging has a strong influence on consumer perception and
purchasing decisions. Packaging is therefore often a decisive factor when choosing between products of similar value.
This paper analyses the quality of packaging prints obtained with four different black (UV and three conventional) inks on
metallised substrates after mechanical impact. In order to assess the quality of the packaging prints, an analysis of the
prints surface was performed, defining the glossiness of the print and the stability of the prints after mechanical impact.
Based on this analysis, results were obtained showing that the print with UV ink (marked B) and the print with
conventional ink (marked A1) showed the greatest changes in spectral reflectance and ink coverage of the print surface
after mechanical impact, while the gloss values changed the most after mechanical impact on the print marked A2 with
conventional ink, and the print B with UV ink showed stable gloss values.
