Abstract
Dot-gain information representative of the dot gain of ink is input for each ink type to be used in printing by a dot-gain information input section ( ), and spectral-density information representative of the spectral density of the ink is input by a spectral-density information input section ( ). Based on the input dot-gain information and spectral-density information, a perforation-size control section ( ) outputs a heating signal (ENS) and a voltage control signal (S) so that the size of a perforation becomes a predetermined printing dot size at all times.
