Digital Production Printing with Dry Full Color UV Curable Toner

摘要

Digital printing will become more and more important in the packaging industry. The functional requirements of printed packaging materials such as heat sealibility, solvent and scratch resistance can only be met by UV curable toners. This paper describes the design and the use of dry colored UV-curable toners in an online printing and curing system. Within the design of the toner, it is very important to choose those raw materials which result in a toner with a high curing efficiency, necessary to cover differences in color, layer thicknesses and printing speed, without affecting the toner properties in a negative way. Combining the benefits of UV curable toner with the high productivity web based digital color Xeikon presses, result in a powerful technology to produce small print runs in a cost efficient way.
