PRINTING DEVICE AND METHOD FOR FORMING PATTERN USING THE SAME

摘要

A printing apparatus is provided to reduce the quantity of used cleaning chemicals required in a cleaning process of a printing plate by using all of a pattern material remaining in a concave parts of first and second printing plates so that the pattern material is prevented from being wasted. A printing roller includes a first printing roller including a blanket having a deposited pattern material and second and third printing rollers(100a) having only blankets. The pattern material deposited in the first printing roller is left in the first, second and third printing rollers in the same way by a printing part. A substrate part(311,312) includes three substrates to which the pattern materials remaining in the first, second and third printing rollers are transferred. A pattern material coating part can deposit a pattern material of a pattern material supply part on the first printing roller. A cleaning part can transfer the pattern material to the substrate and cleans each printing roller.
