Abstract
A printing-plate making apparatus is constructed such that a mode selecting switch adapted to change a master supplying process depending on properties of a master X is disposed on a housing 1 of the printing-plate making apparatus and various conditions, e.g., a master supplying process, locking member 4 for a master supplying roller 3, a temperature preset for a panel heater 33 and a compressing force given by press rollers 35a and 35b are automatically changed to optimal conditions corresponding to masters selected by the mode selecting switch. The printing-plate making apparatus is provided with a master heating switch on the housing 1 of the printing-plate making apparatus and when the master heating switch is actuated, applying of a certain voltage to at least a charger is stopped so that the panel heater 33 arranged at a fixing step is kept in the heated state so as to serve as a master heating unit.
