Research on Image Output Method Based on Optical Fiber Array Features

In the fields of plate printmaking and digital printing, the combination of laser dots and scanning technologies have become increasingly popular for half-tone image output. Targeting the external drum laser scanning imaging system based on optical fiber array, an optical microfiber array with a distance technology suitable for various laser scanning devices is proposed in this paper, which solves the key problems of imaging separation, black scanning area and short focal depth. In addition, a half-tone image output method is designed, which can achieve screen rulings over 175 lines per inch, satisfying the high precision image output requirements of digital plate making and printing.
