PURPOSE:To ensure that not only protuberant parts of a relief printing plate but also recessed parts, shoulder parts and edge parts of the plate can be securely cleaned, by disposing a squeegee roller having a special construction with excellent properties for close contact with a relief printing plate having an uneven surface, in an ink-removing part. CONSTITUTION:The titled cleaner is constituted mainly of an ink-cleaning solvent applying part A, an ink-removing part B and a cleaning part C. An ink adhered to the surface of a relief printing plate is removed by a cleaning brush roller 4. A part for complementary removal of the ink and for squeegeeing a ink-cleaning solvent is provided in the ink-removing part B. At the squeegeeing part, a squeegee roller 5 is disposed facing a moving roller 1f, with the printing plate therebetween. The squeegee roller 5 comprises a multiplicity of annular plates 22 of the same shape and size arranged adjacently to each other in the axial direction, and a rod 24 having a diameter smaller than the diameter of inner holes 23 of the plates 22 is passed through the inner holes 23 of the annular plates 22. By using the squeegee roller 5, it is possible to securely clean not only the protuberant parts of the printing plate but also the recessed parts, the shoulder parts and the edge parts of the printing plate. |
