MEMBER WITH CONCAVE PORTION AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2012/111637

A1

Provided are a member with a concave portion and a method for manufacturing the same which overcome a problem of print soiling. In the member with the concave portion having a printing portion on which a large number of concave portions are formed and a non-printing portion on which the concave portion is not formed on a surface thereof, the surface is brought into contact with a cohesive material to accumulate the cohesive material in the concave portions, and a doctor blade is caused to horizontally stick up on the surface and move relatively, thereby scraping out an extra cohesive material on the surface. The member with the concave portion includes a base member having the printing portion on which a large number of concave portions are formed and the non-printing portion on which the concave portion is not formed on a surface thereof and a DLC cover film formed so as to cover the printing portion and the non-printing portion, and the DLC cover film is polished, thereby forming a plurality of polished traces at an inclined angle other than 0 degree and 90 degrees with respect to a virtual extended line when the doctor blade is caused to horizontally stick up on the surface.
