Equivalent Scattering Area Model of Optical Dot Gain

광학적 망점확대의 상당산란면적 모델에 관한 연구

To investigate relations between Grain-shape of plate and Dot-Gain in the lithography, Printing plates were made by Mechanical Grain, Brush Grain and Electrolytic Grain method.Fine multi-grain by electrolytic method of them resulted in less Dot-grain on the paper, more damping water on the none image part of printing plate.
