PURPOSE:To raise the decorativeness of printings by subjecting a multi-color printing with a heat-softening ink to a hot-pressing process from its printed face by using a mirror-face roll having the same circumferential pitch as the printing pitch. CONSTITUTION:The surface of a polyethylene terephthalate film of a thickness of 6mum, printed with three-color (yellow, red, and blue) in hot-melt inks of a melting point of 70 deg.C, is heated to 75 deg.C and then subjected to a continuous hot-pressing process of a linear pressure of 200g/m by using a Cr-plated iron roll having the same circumferential pitch as the printing pitch of the printing. The film so treated is concurrently ccoled to obtain a printing with a nearly mirror-face inked surface in a continuous manner. When the printing, as a thermal transfer film, is used for printing, the uniform printing with good sensitivity can be obtained. |
