    摘要： An optical beam scanning system for scanning photosensitive material (1) comprises a laser (201), a beam splitter (204) for producing multibeams (LB.sub.a, LB.sub.b), AOM's (207a, 207b), a multibeam adjuster (300) for turning the multibeams to intersect each other at a prescribed point (P.sub.C), a horizontal expander (211), an AOD (213), a vertical expander (214), a deflection direction adjuster (400) for rotating a deflection direction of the multibeams, and a variable focusing mechanism (500) comprising a plurality of object lenses (501-504). A pixel pitch and a spot diameter on the photosensitive material can be changed separately from each other by exchanging the object lenses and by adjusting an angle of intersection of multibeams (B.sub.a, B.sub.b) by means of the multibeam adjuster. Cylindrical lenses of the horizontal and vertical expanders are so positioned that they compensate a cylindrical lensing effect of the AOD.

    摘要： In an electromechanical engraving system, rotogravure calibrating apparatus automatically adjusting the engraving operation of an engraving-head stylus of the system in real time by calibrating a stylus-actuating engraving signal according to a calibration factor relating printed image density to engraved cell depth for a designated engraving screen ruling corresponding to printed image resolution. The calibrating apparatus includes a cell observation and measuring device which obtains data for calculating cell size by imaging the form of individual test cells engraved by the stylus into the surface of a rotogravure printing cylinder, and an engraving signal calibrator which adjusts engraving signal control parameters according to the cell size calculation and to the calibration factor. The engraving signal calibrator derives an image-density/cell-depth reference characteristic computed according to cell size data from cells engraved to correspond to a representative series of test image densities at the designated screen ruling, and computes the calibration factor as a correction of the image-density/cell-depth reference characteristic, generating engraving signal gain data which accordingly adjust the engraving signal actuating the stylus. The engraving signal is rapidly and automatically adjusted through a simplified calibration of the stylus-actuating engraving signal, stabilizing stylus lateral displacement adjustments for consistency among printing operations.

    摘要： An engraving mechanism for engraving gravure cylinders having an engraving head, an engraving head movement mechanism, a sensor coupled to the movement mechanism for sensing the relative position between the engraving head and the gravure cylinder, and a control unit connected to the sensor and the movement mechanism. The control unit has a CPU and memory to store data related to the engraving of one or more gravure cylinders to determine the length of the cylinder in response to movement of the engraving head and sensor information from the sensor, to determine an initial position for positioning the engraving head prior to each engraving operation based upon the length and diameter of the gravure cylinder, and to determine a gap between the engraving head and the cylinder prior to engraving. After the controller unit computes the diameter and length of the cylinder, it controls the movement mechanism to adjust a gap between the engraving head and the gravure cylinder and to position the engraving head lengthwise to the cylinder in an engraving start position. Thus, the engraving start position and the initial gap are automatically varied from one gravure cylinder to another.
