发明名称 Inkjet printing apparatus and preliminary discharge control method of said apparatus
摘要 In an inkjet printing apparatus which performs printing on a printing medium using an inkjet printhead for discharging ink, preliminary discharge, where ink discharge irrespective of printing is performed at the time of print execution, is performed under a predetermined condition to obtain information regarding a discharge state of the printhead. Based on the obtained information, an execution condition of the preliminary discharge is controlled. By virtue of this control, an execution condition (parameter) of the preliminary discharge can appropriately be controlled in accordance with the discharge state of the printhead, in which the ink drying state and the increased viscosity state of ink vary depending on individual differences, usage environment, usage histories (durability) and so on.
