PURPOSE: To contrive to improve printing accuracy and to realize high densification by a method wherein printing is performed by conforming the temperature and viscosity of printing material at its feeding in in pattern to arbitrary suitable temperature and viscosity in response to printing conditions including the characteristics of the printing material employed.

CONSTITUTION: Pinting is performed by conforming the temperature and viscosity or printing material at its feeding in pattern to arbitrary suitable temperature and viscosity in response to printing conditions including the characteristics of the printing material employed. As a device for controlling the temperature and viscosity of the printing material to arbitrary suitable temperature and viscosity, rollers 1 and 2, temperature sensors 3 and 4, an oxygen concentration sensor 5, an opening and closing block 6, a temperature controlling section 7, a nitrogen supplying section 15, a CPU and the like are provided. As a result, the improvement of printing accuracy and densification can be realized and the early deterioration of printing material and the resultant amount of scrap can be prevented from developing and reduced.
