THERMAL HEAD, TEMPERATURE CONTROL METHOD AND OPAQUE APPARATUS

摘要

PURPOSE:To perform opacification with respect to an object such as a plate- making film with high accuracy. CONSTITUTION:An opaque apparatus has a thermal head 32 performing temp. control, a detector detecting the image part or unnecessary part such as a pinhole of an object such as a plate-making film or imaged printing paper, a thermal transfer member 33 having the thermal head 32 and a thermal transfer material, a shading device and a temp. control unit controlling the temp. of the thermal head 32.
