ABSTRACT:
A desired picture or pattern such as a wiring pattern may be recorded on a recording surface bearing a photosensitive material coated thereon by sweeping a light beam obtained from a light beam source and then scanning, with the thus-swept light beam, the recording surface. Sweep position pulse signals are obtained by branching out the thus-swept light beam and detecting same with a photosensor. The light beam output from the light beam source is modulated in accordance with the sweep position pulse signals. The levels of the sweep position pulse signals are changed to a predetermined constant level in accordance with the types of their corresponding picture signals, in other words, the sweep position pulse signals are attenuated where they correspond to picture-bearing portions of the picture or pattern or are amplified where they correspond to picture-free portions of the picture or pattern, so that the synchronization between the sweeping speed and the picture signal reading-out speed is ensured. The above method is useful for the fabrication of distortion-free printed circuits.
