  • Patent number: 10828909
    Abstract: There are provided a thermal transfer printer and a method for producing a printed matter capable of suppressing deterioration in printing quality. A first energizing pulse is generated at the beginning of one line period. The first energizing pulse causes each heating element to perform offset heating. Second energizing pulses whose number corresponds to a tone level are generated in one line period. The second energizing pulses cause each heating element to perform heating. When the timings at which the first energizing pulse and the second energizing pulses are generated can be evenly distributed within one line period, the timings are evenly distributed within one line period. When the timings cannot be evenly distributed within one line period, the timings are distributed within one line period such that an unevenly distributed portion included in the timings is arranged in an initial period of one line period.
