PURPOSE:To provide a plate making method and a plate making device which can be used even in a small factory or office so that easy and simple plate making is possible and a printing plate having high printing durability can be obtd. CONSTITUTION:A master plate 10 for printing having at least a hydrophilic layer, photosensitive resin layer which can be developed and removed, and ink accepting layer having peeling property is used. The plate making method and the device includes a process to form an ink image which influences the photosensitivity of the photosensitive layer by driving an ink-jet recording head by electric signals according to the image signals to inject an ink to the ink- accepting layer formed on the photosensitive resin layer of the master plate, a process to expose the printing master plate 10 with the ink image formed, and a process to develop while the ink accepting layer is peeled. |
