AI Technical Summary

Technical Problem

The existing methods using a transfer liquid with an adhesive component to adhere ink to a recording medium can result in the ink layer peeling off due to external forces applied to the exposed side of the ink layer.

Method used

A liquid ejection device that includes a head for ejecting ink and a transfer liquid ejection unit, with a control method that ejects ink onto an image formation area and subsequently ejects transfer liquid onto an expanded area surrounding the image formation area, ensuring the ink layer is fully covered by the transfer liquid layer.

Benefits of technology

Prevents the ink layer from peeling off by covering its sides with the transfer liquid layer, maintaining the integrity of the printed image.

Abstract

The present invention prevents separation of an ink layer.　A printer according to the present invention comprises: a head that discharges ink I; and a transfer liquid discharge unit that discharges transfer liquid A having an adhesive component which adheres the ink I to a recording medium. A CPU of the printer carries out an ink discharging step for causing the head to discharge the ink I onto an image formation region R1 of a film 70 and a transfer liquid discharge step for causing, after the ink discharging step, the transfer liquid discharge unit to discharge the transfer liquid A onto an expansion region R3 of the film 70, which includes the image formation region R1 and adjacent regions R2 adjacent to the image formation region R1 in the front-rear direction D1 and in the left-right direction D2.
