Patent ID: 7471304

Claim:
A card manufacturing method for manufacturing a card with use of an intermediate transfer film in which a protecting layer and an ink receptor layer are laminated on a strip-shaped base in this order, the intermediate transfer film having a first transcriptional region and a second transcriptional region defined in common with the protecting layer and the ink receptor layer, and an ink film having respective ink areas formed on a film base successively, the ink areas having a plurality of sublimation-ink areas in different colors and an invisible-ink area, the card manufacturing method comprising: a sublimation-ink image forming process of transferring a plurality of sublimation inks in the sublimation-ink areas of the ink film to the ink receptor layer in the first transcriptional region of the intermediate transfer film in superimposition, thereby forming a sublimation-ink image in the intermediate transfer film; an invisible-ink image forming process of transferring an invisible ink in the invisible-ink area of the ink film to the ink receptor layer in the second transcriptional region of the intermediate transfer film, thereby forming an invisible-ink image in the intermediate transfer film; a first re-transfer process of re-transferring the ink receptor layer and the protecting layer in the first transcriptional region of the intermediate transfer film to a card base of the card so that the protecting layer in the first transcriptional region is arranged on a front side of the card; and a second re-transfer process of re-transferring the ink receptor layer and the protecting layer in the second transcriptional region of the intermediate transfer film onto the protecting layer in the first transfer are so that the protecting layer in the second transcriptional region is arranged on a front side of the card.
