Abstract (en)

Data concerning a transfer pattern of lamination transparent film is not externally sent and stored in a memory but generated by a random pattern generating module 23 of a color controlling DSP 22. A random number generating section 23a generates a pseudorandom number for each dot of one line; a tone data obtaining section 23b obtains tone data corresponding to the pseudorandom number; and a transferring section 23c transfers the tone data to a head signal converting ASIC 24. Tone data for each dot of one line is alternately written in line buffers 1 and 2. Using the tone data written in the line buffers 1 and 2, a thermal head 130 transfers transparent film 120F.
