METHOD FOR PREPARING SCREEN STENCIL BY SEMICONDUCTIVE LASER

摘要

PURPOSE:To attain to make a laser apparatus compact, by utilizing semiconductive laser in the preparation of a screen stencil. CONSTITUTION:A control apparatus 1 inputs the information signal from a reading apparatus 2 reading an image on a manuscript and converting the same to time series image information and is connected to a semiconductive laser processing apparatus 3 operating on the basis of an output signal obtained by the conversion of the information signal. The semiconductive laser 7 from the processing apparatus 3 is utilized to perform the drilling 8a of base paper 8 to prepare a screen stencil. By utilizing the semiconductive laser, a power source part is made compact and the miniaturization of the processing apparatus 3 itself it attained.
