Abstract
Abstract A mesh roller for planography. Its external surface is formed with a protruded surface and a plurality of fine cells for storing ink. The surface is made of or covered with a combination of a high hard material and a lipophilic metal material. According to the first aspect, the center area of its protruded surface is composed of or covered with a lipophilic metal material and the border edge between the protruded surface and the cells is composed of or covered with a high hard material. According to the second aspect, the protruded surface is composed of or covered with a mixture of a high hard material and a lipophilic metal material which are finely mixed each other. This mesh roller can be provided with a superior wear resistance against a high pressed scraping motion of a doctor blade and a high ability of ink reservation by preventing a lipophilic metal material from water soiling.
