Abstract

PURPOSE:To lessen labor in a light shielding method so that a uniform light shielding operation can be made without depending on a skilled person by instructing a detected unnecessary part, etc., to a light shielding device and forming a light shielding layer to a film for plate making, etc., except the required light transmissive or reflecting part which is the image part by said device. CONSTITUTION:A thermosensitive transfer printer is used as a thermosensitive transfer recorder which is the light shielding device. On the other hand, an object 1 to be inspected which is the film for plate making is fixed and placed to the rear face of glass 2 so as to be illuminated by a light source 6 for illumination and is subjected to the visual inspection of the unnecessary part such as pinhole and the necessary image part. An instruction to a thermal head 4 of a thermosensitive transfer printer is executed simultaneously with the detection by a cursor 3 having an instruction mechanism. The thermal head 4 moved by the positional information instructed by the cursor 3 is moved and the light shielding material 4 is thermally melted, by which the shielding layer is formed to the detected unnecessary part of the object 1.
