Abstract
An ink-jet printing apparatus performs a printing process by discharging ink from color ink heads and treatment liquid from a liquid head for making the ink insoluble or coherent. The printing apparatus has the minimum amount of memory required to eject the treatment liquid as far as possible and performs excellent printing. For discharge data of one scanning performance of the color ink heads, the apparatus has only memories for each color ink head. Discharge data for the treatment liquid is formed by a treatment liquid discharge data creating portion based on the data stored in the memories upon switched by data-switching portion. Then the discharge data for the liquid head is supplied to the head after being stored in a buffer as much as the number of orifices of the head.
