Colorants for Digital Printing: A Challenge for Development

摘要

Electrophotography and ink jet are the most important NIP (non-impact printing) technologies in digital printing. Colorants for electrophotographic systems have to fulfill special requirements which can be very different compared with colorants used in conventional printing inks and which can also differ for each toner type. Ink jet inks are much closer to traditional printing inks, but still there are many important differences. The presentation will discuss the challenges in the development of pigments and pigment preparations for electrophotography and ink jet applications.
