Abstract

PURPOSE:To perform the reproduction of multiple gradation, by performing recording in the combination of a means for attaining the modulation of a dot diameter by the modulation of signal voltage or application time and an area gradation method such as a dither method or density pattern method. CONSTITUTION:In current passing transfer recording, an ink ribbon or sheet 1a (1b) and recording paper (paper to be transferred) 2 are combined and pulse like voltage is applied to the surface of the ink ribbon or sheet 1a (1b) from a stylus 3 and ink is melted by Joule heat by the current flowing at this time to be transferred to the recording paper 2. In recording, a means for attanining the modulation of a dot diameter by changing signal voltage or application time is combined with an area gradation method (a dither method or density pattern method) to perform the reproduction of multiple gradation of 16 gradation or more. By this method, not good density gradation is obtained but also a sharp transfer image can be recorded becase the dot of each level is sharp and saturation density becomes high.

In the thermal transfer recording method, for example, the recording materials include (l) a dye layer and a wax layer sequentially provided on a paste layer, and (2) an ink layer in which an ink consisting of a dye and a low melting point agent is mixed with a filler. , (3) an ink layer provided on a base layer via an adhesive layer, and (4) an ink layer and a color developing layer overlaid to form a color have been proposed.

In the inkjet recording method, for example, the dot diameter is changed by changing the A pulse width by devising the nozzle, and this
It has been proposed to combine (2×2) matrices. However, with the method of changing the recording density by changing the applied voltage or the applied time, it is not possible to express many gradations. Furthermore, in the thermal transfer recording described above, the layer structure of the recording material is complicated, and the saturation density tends to be lower than before. The above-mentioned inkjet recording uses dye as the coloring material, so it has insufficient fastness (light fading, heat fading, water fading, etc.), and there are reliability problems such as low saturation density, and the dot diameter level is also 4. The value is current.

In addition, the current transfer recording method of the present invention is characterized by thermal transfer (
1) In thermal transfer recording, if the entire ink layer is transferred, gradation will be lost, so a method is used in which only a portion of the ink is transferred.In contrast, with the method of the present invention, although the degree of transfer changes in the area direction, , essentially all the ink is transferred from the paste layer, so the dots at each level are also sharp and have a high saturation density; and (It) inkjet recording uses water-soluble dyes.
