LIQUID DISCHARGE APPARATUS, CONTROL METHOD OF LIQUID DISCHARGE APPARATUS, AND DEVICE DRIVER, AND PRINTING SYSTEM

摘要

The degree of thickening of ink for each of nozzles based on dot pattern data is calculated based on a thickening value Z(n+1)=Z(n)×a×bss×bmm×bll, and information the dot pattern data corresponding to the nozzle, which indicates that small dots are formed in when the thickening value is equal to or greater than a threshold is replaced with information indicating that middle dots which are larger than the small dots are formed.

1. A liquid discharge apparatus comprising:
a liquid discharge head that includes a plurality of nozzles, discharges a liquid from the nozzles by driving of an actuator, and then forms dots with impacted liquids on an impacted object; a driving waveform generation circuit that generates a driving waveform for driving the actuator; and a control circuit that controls discharging of the liquid by the liquid discharge head based on discharge data including information indicating a size of a dot formed on the impacted object, wherein the control circuit calculates a degree of thickening of the liquid for each of the nozzles, and discharges relatively large dots compared to small dots to an area on which relatively the smallest dots are supposed to be formed from the nozzles based on the discharge data when the degree of thickening of the liquid in the nozzle becomes a predetermined state which is determined in advance.
