Abstract
Provided is a jacket to be installed on a surface of one of impression cylinders and transport cylinders. The jacket is produced by the following process. Super hard particles, such as ceramic particles, are scattered on a surface of a sheet-shaped base member. A plating layer is then formed on the surface of the base member in a way that a convex and concave profile formed of the super hard particles is left. In the plating layer, fine particles of low surface energy resin are uniformly dispersed.
Claims19
A jacket for any one of impression cylinders and transport cylinders of a printing press, which is wound therearound and installed thereon for preventing ink from adhering thereto, comprising:
- a sheet-shaped base member;
- super hard particles scattered over a surface of the sheet-shaped base member, such that a space is provided between adjacent super hard particles;
- and
- a metal plating layer plating the surface of the base member by composite of plating containing fine particles of ink-resistant and ink-repellent low surface energy resin in metal matrix to fix the super hard particles on the surface of the base member in a way that a convex and concave profile formed by the super hard particles is left,
- wherein the super hard particles are fixed to the sheet-shaped base member by the metal plating layer including the fine particles.

- a sheet-shaped base member;
- super hard particles scattered over a surface of the sheet-shaped base member, such that a space is provided between adjacent super hard particles,
- a first metal plating layer fixing the super hard particles onto the base member, and
- a second plating layer plating a surface of the first metal plating layer by composite of plating containing fine particles of ink-resistant and ink-repellent low surface energy resin in metal matrix a way that a convex and concave profile formed by the super hard particles is left,
- wherein the super hard particles are fixed to the sheet-shaped base member by the first metal plating layer and the second plating layer.
