Platemaking device

Abstract

A screen printing plate is arranged on the front of a back plate vertically placed on a base, positioned by the base and a positioning member, and fixed by a fixing member. A thermal head is moved in respective directions of X, Y, Z by respective moving parts MX, MY, MZ, and a desired image is made on a screen. Since the screen printing plate is perpendicular to a horizontal plane, dust and the like slips on a surface of the screen printing plate and moves outside a platemaking area even if they drop on the screen without adhering to the surface. The Z-axis direction moving part MZ is provided with a Z-direction energizing unit and if a position in a Z-direction of the thermal head is adjusted by the Z-axis direction moving part MZ, force with which the thermal head presses the screen printing plate can be finely adjusted.
