A cylindrical printing plate formed with high precision and used for printing on a metal can body, particularly an aluminum or aluminum alloy can body. The forming method of a printing plate forms the printing plate to be mounted on an outer periphery of a cylindrical plate cylinder, and includes a notch forming step of forming a positioning notch in a rectangular elastic material sheet in which a resin layer to be served as a plate section is formed on one surface. A cylindrical material forming step rolls the elastic material sheet in which the positioning notch is formed and overlaps both end portions of the elastic material sheet and joining them in a cylindrical shape. A plate section engraving step engraves a printing pattern on the plate section of the elastic material sheet formed into a cylinder shape.

There is disclosed a condensation curable coating composition in the form of an oil-in-oil emulsion, the coating composition being able to protect surfaces coated therewith from undesired contamination by materials coming in contact therewith. The surfaces to be so protected by the coating composition, once cured, can, by way of illustration, be of parts of printing systems and the materials coming in contact with such surfaces can be ink images or residues thereof.

A medium transport device includes a roller transporting a medium, such as recording paper; a first layer covering a surface of the roller facing the medium; a second layer laminated on the first layer; and convex portions provided between the first layer and the second layer, and the convex portions are formed from inorganic particles. The first layer binds the convex portions to the roller, and the second layer covers the convex portions for protection.

A machine according to at least one embodiment of the present invention comprises a rubber material to be supplied with an oil product containing a softener, wherein an absolute difference between a solubility parameter of the softener and a solubility parameter of the rubber material is 1.7 or less. The machine having a communication portion connecting the rubber material and an outside of the machine, and is configured to supply the oil product from a first end of the communication portion to a second end of the communication portion.

A process for producing a fluid transfer surface, which process comprises: providing a titanium or titanium alloy surface; subjecting the titanium or titanium alloy surface to surface hardening by interstitial element absorption to provide a hardened surface; and, if required engraving the hardened surface to provide a desired surface topography.
