Liquid discharge apparatus

A liquid discharge apparatus comprising:

• a first shift register in which a first region configured to hold data having a first data size, a second region configured to hold data having a second data size, and a third region configured to hold data having a third data size are continuous;
• a plurality of discharge sections configured to discharge droplets based on head control data held in the first shift register;
• and
• a first wiring for transmitting the head control data to the first shift register, wherein
• the apparatus is configured to be operated in a first print mode in which the droplets are discharged from the plurality of discharge sections and printing is performed with a first gradation number, based on the head control data, and in a second print mode in which the droplets are discharged from the plurality of discharge sections and printing is performed with a second gradation number smaller than the first gradation number, based on the head control data,
• in the first print mode, a data size of the head control data is a sum of the first data size, the second data size, and the third data size, and
• in the second print mode, a data size of the head control data is a sum of the first data size and the second data size.
