Title: Printing method
Inventor: ENDO KAZUO
IPC: B41M1/26
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the tension control of a film even in printing that lacks transferability and adhesiveness by heat softening the printing surface of the film and keeping other portion at a temperature same as before or lower than that. SOLUTION: Only the surface of a film that is intended for printing and coating is heat softened before printing and coating, and the opposite side of the film that is intended for printing is kept at a temperature by same as before cooling by a cooling roller 7 to prevent it from shrinking. As a heater to heat only the surface, a thermal roll 2 or a near infrared heater or hot air is used. To suppress an increase in heat inside due to conducted and radiant heat associated with surface heating, the whole is maintained in a condition same as before by cooling the opposite side, and heat-softening only the surface to which ink adheres. Therefore, it becomes possible to increase transferability and adhesive strength and to prevent the film from shrinking and maintain adhesiveness without tension control.
