PURPOSE:To enable high quality printing to be given on the surface even in a flexible synthetic resin vessel having a printing surface being unstable in its shape and irregularly deformable through compression. CONSTITUTION:This printing method is featured such that a flexible synthetic resin vessel 3 to be printed is molded by blow molding and then sealed. Prior to printing, fluid within the flexible synthetic resin vessel 3 is heated by an infrared ray heating device 4 so as to render the inside pressure positive. A rubber blanket 1 is put on the surface of the flexible synthetic resin vessel 3 having a positive inside pressure. |
