摘要:
In order to propose a dry process technique of producing a printing roll having safe and beauty concave portions for printing image area without discharging environmental contaminating substance and a new technique for improving quality of printed matters, this invention is to provide a printing roll with DLC film layer in which laser beam-engraved grooves as concave portions for printing image area are formed on a carbide cermet spray coating formed on a surface of a roll substrate, and a method wherein a carbide cermet spray coating is formed on a surface of a roll substrate roughened by a blast treatment, the surface of the carbide cermet spray coating is ground or ground-polished, then a DLC film is formed on the ground or ground-polished surface and thereafter laser beam-engraved grooves are formed on the surface of the DLC film as a concave portion for printing image area.
