摘要： The method and apparatus make a printing plate such as a lithographic printing plate by exposing an original plate of the printing plate such as a presensitized plate in a substantially oxygen-free state. The method and apparatus deprive substantially of oxygen at least an exposed area of the original plate being exposed to light at least during exposure and expose the original plate to the light at a wavelength of between 250 nm and 420 nm. The original plate has on a support an image recording layer containing a polymerization initiator, a polymerizable compound and a binder polymer, being sensitive to the light at the wavelengths of between 250 nm and 420 nm, having no oxygen barrier layer, and being removable with a printing ink and/or a fountain solution. That is, a latent image is formed by photo-polymerization on the original plate and the original plate is subjected to development on a printing press.

摘要： An inner drum exposure apparatus is disclosed in which a linearly polarized light beam emitted from a light source is converted to circularly polarized light. This in turn is passed through a single-axis crystal optical element so as to be split into equal light quantities of an ordinary ray and an extraordinary ray in a sub-scanning direction. These rays are subsequently reflected at a reflective mirror surface of a scanning unit so as to be focussed at a beam spot which is distributed on a recording medium in an approximately rectangular configuration with respect to the sub-scanning direction and has steep edge portions, thereby performing exposure processing.

摘要： An array refracting element for dividing laser beams in a sub-scanning direction, which is formed by linearly disposing a pair of refracting members, each having a unit surface shape for dividing one incident laser beam into two and emitting the divided laser beams, so that directions in which the laser beams are divided are coincident with each other and so that the refracting members locate along the division direction, is disposed on an optical path of the laser beams emitted from plural semiconductor lasers, and between a laser-beam outgoing opening of a fiber array section and a recording film. As a result, an array refracting element and an exposure device, which can improve quality of a recording image at an exposure recording apparatus at a low cost, can be obtained.
