It is. In FIGS. 2a and 2b, R indicates red, G indicates green, and B indicates blue, and 5 is a cartridge frame made of thermoplastic columns having a large number of holes. The operation of the color filter configured as described above will be described below with reference to FIGS. 1, 2a, and 2b.

多色パターンが得られる。First, FIG. 1 shows a platen in which the transparent substrate 1 moves intermittently in the direction of the arrow, and while the movement is stopped, the solid ink 2 descends and is pressed into contact with the transparent substrate 1. Since the roller is being heated and the temperature of the transparent substrate is also rising, the temperature is higher than the melting point of the solid ink, and a small amount of the solid ink melts and is stamped onto the surface of the transparent substrate 1 to obtain the multicolor pattern 3.

ンが得られる。Next, when the first stamping is completed, the solid ink rises up by one pixel and the platen roller 4 moves in the direction of the arrow and in the direction perpendicular to the paper surface, and the second stamping starts. In one stamping cycle, a staggered pattern is repeated in the vertical direction of the paper and returns to the original position, resulting in a multicolored pattern.

A satisfactory solid ink is obtained by stretching to obtain a multicolor pattern of 16 dots/mm squared.
