For the temperature adjustment process that uses high viscosity ink and is based on table No. 1, in a low temperature environment, an ink refill failure may occur and lower density may appear in high duty printing. Also for the temperature adjustment process that uses high viscosity ink and is based on table Nos. 2 and 3, in a low temperature environment, an ink refill failure may occur and lower density may appear. On the other hand, for a temperature adjustment process that employs table No. 4, a smaller pre-heat pulse width than that for table No. 1, for the conventional temperature adjustment, is employed in the same low temperature environment. Therefore, an ink refill failure does not occur, and horizontal or vertical gaps do not appear during high duty printing.
