Title: PATTERNED ROLL AND METHOD FOR MANUFACTURING SAME
Abstract:
Provided is a patterned roll which is patterned by means of diamond-like carbon (DLC) and which eliminates the problem of side etching; also provided is a method for manufacturing this patterned roll. A DLC coating film is formed on the surface of a base material, and this DLC coating film formed on the base material is irradiated with a pulsed laser to perform laser abrasion, thereby forming a DLC pattern on the surface of the base material. This patterned roll preferably is characterized in that the laser irradiation is performed using a pulsed laser having a pulse width of a nanosecond or less.
