Title: Recording method
Inventor: KAWAKUBO TOSHIO
IPC: B41N1/14
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To realize the efficient transferring of ink from a plate surface to a blanket or directly to a paper without hardly scattering in the quality of transferring by a method wherein an elastic layer is provided so as to be employed as the base of a recording body or provided on the surface of a plate cylinder, to which the recording body is fixed. SOLUTION: The utilization of a rubber material as an elastic layer is profitable from the view point of a contact pressure necessary between a recording body and an ink roller and of a contact pressure necessary between the recording body and a paper. By giving an elasticity to the base of recording body, the unevenness of the ink roller, the paper or the like can be absorbed, the contacting properties between the recording body and the ink roller or the paper can be enhanced. In addition, even the unevenness of the elastic layer itself, which develops at the working of the elastic layer, can be absorbed through the use of the elastic layer. When the base of the recording body is made thinner from the view point of cost, the holding of the recording body to a plate cylinder becomes difficult. In order to improve the holding of the recording body and the surface accuracy, the provision of the elastic layer on the surface of the support of the plate cylinder is effective. Further, the provision of two elastic layers is profitable under the condition that a thin comparatively hard elastic layer is provided on its front surface side, while a comparatively soft elastic layer is provided beneath the thin comparatively hard elastic layer.
