发明名称 PLATE CYLINDER DEVICE OF INTAGLIO
摘要 PURPOSE:To obtain a high quality plate cylinder reusable and suitable for printing a modest number of sheets by so providing a thermally-melting type filler in a cell formed on a plate surface that the volume of said filler is changed in correspondence to the density of an image by a laser. CONSTITUTION:A uniform cell 15 is etched with the depth (t) in a network on the plate surface of a plate cylinder 6, so that the whole plate surface is in a solid state at the printing time. Then, a filler 16 of thermally-melting type is applied all over the plate surface. The filler 16 is such that is obtained by allowing carbons or the like to be contained in a wax which has a relatively narrow distribution of melting points, showing some hardness when it is cured and reduced viscosity when it is melted. The filler 16 is scattered by radiating a laser 18 into the cells. In this case,k if the laser is modulated or the radiating time of the laser is changed for each cell, the capacity of a recess in the cell where the filler is dispersed or sublimated can be adjusted. Therefore, the recess 19 having the volume corresponding to the gradation can be formed.
