Claim Text:
1. A line type liquid discharge apparatus comprising: a line type 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 line type 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 degree of thickening of the liquid for each of the nozzles, 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 first state which is determined in advance, and discharges relatively the smallest dots to an area on which relatively the smallest dots are supposed to be formed based on the discharge data when the degree of thickening after becoming the first state returns to become a second state before becoming in the first state.
