The influence of printing resolution on specific tone values printed with UV curing inkjet

The Roland printing UV machine recently acquired by the Faculty of Graphic Arts in Zagreb is the example of continuing development of the digital printing technology. The printing machine uses inks that dry by UV light. Research is needed to fully understand the process and advantages and limitations of an UV drying machine. This paper covers different aspects of the process. Samples printed on three different printing resolutions were analyzed in order to observe their differences. This was done by analyzing their gamut, measuring their L*a*b* values and comparing them to ISO offset, examining them with image analysis apparatus and by comparing their reflectance rate. The results that, when increasing the printing resolution, the droplet size of the ink decreases and that the number of droplets increase.
