Multi-color thermal transfer recording method

Abstract

Abstract PURPOSE:To obtain multi-color recording by one recording operation without performing difficult positional determination, by irradiating an ink film, wherein a plurality of color inks are separately applied to small regions, with lights having a plurality of wavelength componenets to selectively melt inks before performing recording. CONSTITUTION:A multi-color thermal transfer recording sheet 2 is prepared by separately coating a transparent base film 2a with three red, blue and yellow inks R, B, Y in a state separated into small regions. Light sources 4a, 4b, 4c respectively have different wavelength regions and lights therefrom are focused to the side of the base film 2a of the ink sheet 2 by a lens 5. The beam diameter at this focus is the size of a recording dot and shown by the part 6. That is, red and yellow inks are melted by the light source 4a, the red and blue inks by the light source 4b and the blue and yellow inks by the light source 4c and, when three light sources 4a, 4b, 4c are simultaneously operated to irradiate lights, three red, blue and yellow inks are simultaneously melted.
