Abstract

PURPOSE:To attain to enhance reproducibility of black and printing quality, by correcting the ink of the first layer superposed to and contacted with the region showing a certain color phase of a second layer so as to reduce the content of the color component constituting the certain color phase as compared with that of the ink superposed to and contacted with the region of the second layer showing a separate color phase. CONSTITUTION:Black heat-meltable ink is applied to a film substrate 3a to form a first layer 3d and heat-meltable inks Y, M, C are successively applied to said first layer 3d to form a second layer 3e. Herein, B of the first layer 3d is corrected to a color phase obtained by subtracting a small amount of Y from B, that is, a color phase B (M+C) based on M and C at the place opposed to Y of the second layer 3e. Similarly, the place opposed to M is constituted of B (Y+C) and the place opposed to C is constituted of B (Y+M). Heat energy supplied to a thermal head 1 is stepwise controlled to selectively print the first layer 3d or the second layer 3e of an ink film 3. In this case, in the place of Y of the second layer 3e, the black of the first layer 3d is corrected in the relation with the color phase of Y and real black printing can be performed based on a subtractive color mixture method. The place of M of the second layer 3e is same.

Since it is necessary to print M and C three times overlapping each other, (1) the printing speed is significantly lower than that of single-color printing. Since overlapping is required three times, the scanning mechanism of the thermal head 1 requires extremely high precision positioning technology to prevent color misregistration. (2) Since Y, M, and C of the ink film 3 are consumed in large quantities, there is a drawback that the printing cost becomes high. Here, as shown in Figure 3,
It has been proposed that the ink film 3 for thermal transfer is composed of multiple layers to eliminate the above-mentioned drawbacks. In the same figure, 3b is each color Y
