Abstract
This paper aims to examine the lightfastness of yellow water-based ink using a light-accelerated aging chamber. Mondy Maestro Print uncoated offset paper (120 g/m²) was used as printing substrate. The printing was carried out on an inkjet printing machine using water-based inks, and the light exposure was tested within the Solarbox climate chamber. The study was conducted through the analysis of colour differences, as well as changes in chroma and lightness, across light, mid and dark tonal patches, as well as the paper substrate. It is hypothesised that the paper substrate will influence the tonal patches through its changes, and that the colour differences will be greater with higher tonal coverage. Experimental results obtained throught spectrophotometric measurements indicate significant color differences. It was found that the paper substrate, through its alterations, influenced the yellow tonal patches. Furthermore, higher tonal coverage resulted in more pronounced colour changes. An exception was observed in the 70% tonal value (TV), which exhibited greater changes compared to the solid patch. These studies are crucial for better understanding of the application and efficiency of this type of ink in the graphic arts industry.
