An investigation into screen printing using UV process colour inks

This paper presents the results from a comprehensive exploration of printing sequence based on dot gain, colour gamut and grey balance characteristics for screen printing. The tests involved designing a test image and this included the successful incorporation of a novel feature to explore grey balance. This allowed the three process colours, cyan, magenta and yellow, to be varied independently. The results confirmed the excellent repeatability of the process when printing a conventional UV ink. The results also showed the small impact of increasing the ink base up to 30% on tone gain and the colour range was not affected by the printing sequence.
