Abstract
Laser phototypesetting and computer to plate (CTP) technologies are widely used in print industry. These technologies are based on the complex photosensitive image process. The exposing and development processes result in waste of photosensitive materials and environment pollution. Green plate making technology is not based on photosensitive materials but nano-materials. The image process of the technology is to jet the nano-composite transfer printing material on super hydrophilic print plate with special nano and micro-structure. Then the oleophilic image area and hydrophilic non image area are formed by adjusting interface characters between the nano-composite transfer printing material and super hydrophilic print plate. The plate is used for printing without exposing and development. Without photosensitive image process, the technology has many advantages such as no operation in darkroom, simple process, environmental friendly and low cost. The key problems of print resolution and press life have been solved effectively by preparation of nano composite transfer printing material and super hydrophilic print plate. In this paper, the research process of the nano composite material and the print plate are presented.
