AI Technical Summary
Technical Problem
Frictional heat generated between a blade and a printing cylinder during the scraping of excess paste can alter the viscosity of the paste, leading to a decrease in transferability in gravure printing processes.
Method used
A printing cylinder design featuring a core portion with a cylindrical surface layer having recesses and protrusions on the outer and inner circumferential surfaces, coated with a low-friction DLC coating and gaps for improved heat dissipation, mitigating frictional heat effects.
Benefits of technology
The design suppresses frictional heat, maintaining paste viscosity and enhancing transferability by improving heat dissipation efficiency, thereby stabilizing the printing process.

Abstract
The present invention provides a printing cylinder that improves transfer performance by suppressing the effects of frictional heat generated between the cylinder and the blade. [Solution] The printing cylinder 10 comprises a core portion 11 having a cylindrical or columnar shape, and a cylindrical surface portion 12 covering the circumferential surface 11a of the core portion 11. The cylindrical surface portion 12 has an inner circumferential surface 12b facing the circumferential surface 11a and an outer circumferential surface 12a located on the opposite side of the inner circumferential surface 12b. Multiple recesses 120 are formed on the outer circumferential surface 12a. Multiple protrusions 210 are formed on the inner circumferential surface 12b.
