Abstract
The present invention discloses a method for thermally transferring an ink pattern to a recording medium, comprising the steps of preparing an ink sheet provided with a hot-melt and/or hot-sublimable ink layer and a transparent material sheet provided with a transparent hot-melt material layer, thermally producing an ink pattern on the transparent material layer of the transparent material sheet by heating the ink sheet with thermal head, and thermally transferring the ink pattern to the recording medium together with the transparent hot-melt material layer. And an another method comprising the steps of preparing an ink sheet having a transparent hot-melt material frame layer and a hot-melt and/or hot-sublimable ink frame layer, thermally transferring the transparent hot-melt material frame layer onto a surface of a platen roller, thermally producing an ink pattern on the transparent hot-melt material frame layer on the platen roller by heating the hot-melt and/or hot-sublimable ink frame layer with a thermal head, and thermally transferring the ink pattern together with the transparent hot-melt material frame layer onto a recording medium.
