Key Words: Reverse gravure-offset printing (리버스 그라비아 옵셋 인쇄), Gravure-offset printing (그라비아 옵셋 인쇄), OLED (유기발광다이오드), Auxiliary electrode (보조전극), Ag nano paste (실버나노페이스트) 1. Because gravure is capable of transferring more ink to the paper than most other printing processes, it is noted for its remarkable density range (light to shadow) and hence is a process of choice for fine art and photography reproduction, though not typically as clean an image as that of offset lithography. ... matter to the reverse effective drying. Compare rotogravure printing to traditional relief printing (when an image is raised from the surface of the printing plate), and packaging experts immediately detect that when the depressions, or intaglio areas, are filled with ink, the dynamic tonal gradations are virtually limitless as one varies the depths of these depressions. A shortcoming of gravure is that all images, including type and "solids," are actually printed as dots, and unless the ink and substrate combination is set up to allow solid areas to flow together, the screen patt… The Reverse Gravure method will need to add approximately 20% to the desired coat weight and for Offset Gravure method add approximately 75%. Basic working principle of RG coating is demonstrated using photo-active materials. For the use of G STAR at other speeds (>400m/min), please contact your local Technical Department.
