PROBLEM TO BE SOLVED: To provide a printing device wherein the formation of a plate can be easily performed, and in addition, the plate can be reversely reproduced; and its machine plate. SOLUTION: This printing device is equipped at least with a mechanism which forms a latent image on the plate, a mechanism which sticks a water- color ink on the plate wherein the latent image is formed, and performs the development, and a mechanism which transfers the developed image onto a paper. In the machine plate of such a printing device, the ink adhered section of the latent image on the machine plate is ink-acceptable. Also, after the processes for the development and the transfer are completed, the latent image on the machine plate is irradiated with light and washed with water, and dried to delete the latent image. Thus, the machine plate can be converted to a machine plate on which a new latent image can be formed. For this printing device, such a machine plate is used, and the machine plate is manufactured by such a machine plate manufacturing method. |
