Light Fastness Comparison of Xerography and Inkjet Presswork

Abstract

Following the development and combination of digital printing techniques and digital distribution in publishing industry, more and more books are printed by digital printing equipments. The stability for storage became one of the focuses in digital printing research. The aim of this research work is to investigate the different storage resistance property between digital xerography and inkjet printing presswork. In this paper, a fastness experiment, carried out in completely natural lighting conditions, was presented. A mathematic model of ink aging performance was got from the curve fitting of test results. The key influence impacts in prints aging were compared and analyzed according to the change of density between before and after sun lighting. Finally, the fastness properties of the two categories of digital prints were generalized.
