摘要： PROBLEM TO BE SOLVED: To provide an original plate of a lithographic plate which enables improvement of plate wear resistance. SOLUTION: This original plate of the lithographic plate is constituted in such a manner that the upper layer of an image recording layer 16 formed on a substrate 12 contains a pigment having a photothermal conversion rate not so high as that of dye, but being hardly discolored by light, while the lower layer of the layer 16 contains a dye having a high photothermal conversion efficiency, but tending to be discolored by the light. On the occasion when the image recording layer 16 is exposed to the image recording light, the temperature is raised by making the upper layer part hardly discolored by the light absorb the light so that the light be attenuated moderately, and the lower layer part is heated at once by the light passing through the upper layer and being attenuated, while the dye is kept from being discolored by the light. Thereby the temperature of the interface between the image recording layer 16 and the substrate 12 is raised efficiently. Thus the image recording layer 16 in the region of the interface is hardened firmly and the plate wear resistance is improved. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an inner drum exposure system in which irregularity of recording is suppressed; isolation spacing is improved in accuracy; an exposure rate is prevented from falling by reducing weight when preparing an isolating element on an optical deflector, to suppress falling of rotation speed; and it is made possible to manufacture an inexpensive exposure scanning system. SOLUTION: Two laser beams which are emitted from light sources 30A, 30B and are independently modulated by respective optical systems on the light source sides based on image signals are polarized and multiplexed by a polarization beam splitter 38, and the two laser beams are made into right-handed circularly polarized light and left-handed circularly polarized light to be emitted to a scanning optical system. The two laser beams, which are the right-handed circularly polarized light and left-handed circularly polarized light, made incident from the optical system of the light source side are converted to the linearly polarized light perpendicular to each other by a quarter-wave plate 26 arranged on the optical path of the scanning optical system. After that, exposure processing is performed by emitting the two laser beams transformed into linearly polarized light perpendicular to each other through an uniaxial crystal 28 and the quarter-wave plate 26 from different positions, respectively, so that the main outgoing beams of light become parallel.

摘要： PROBLEM TO BE SOLVED: To provide a multi-beam exposure device for stably recording halftones, by using a means for selectively on/off turning a plurality of pixels of a two-dimensional optical modulator or the like, and using an FM screen. SOLUTION: The multi-beam exposure device miniaturizes so as to make an exposure beam spot BS flat, in the scanning direction by arranging a means for making the diameter small at a position being a parallel light flux on an optical path, at a position having a substantially conjugate relation with the lens system imaging position on an optical path leading to the upper part of an exposure face of a recording medium, from a light source installed on an exposure head. Thereby the multi-beam exposure device makes the edge part of the both sides of the scanning direction exposure amount distribution in each beam spot BS forming one dot steep, and performs exposure processing, in a state where the longitudinal direction both sides of the edge part is along the scanning direction. The exposure head preferably suppresses image unevenness, in a direction orthogonal to the scanning direction so as not to be influenced by the variations in the coloring threshold of the recording medium and intensity variation or the like of a laser beam, and records so as to express the intermediate tone stabilized by using the FM screen.
