  • Publication number: 20220174159
    Abstract: A liquid discharge apparatus includes a first detection unit to detect a first movement amount of a recording medium. The apparatus includes a first liquid discharge unit, a first image capturing unit to capture a first image of the medium in a capturing range between the first detection unit and the first liquid discharge unit, a second image capturing unit to capture a second image of the medium in the capturing range between the first discharge unit and the first capturing unit, a second detection unit to detect a second movement amount of the medium based on the first and second images, a first determining unit to determine a discharge timing of the first discharge unit based on the first and second movement amounts, and a second determining unit to determine a capturing timing of the second capturing unit based on the first and second movement amounts.

  • Publication number: 20220143971
    Abstract: A droplet discharge apparatus includes a control device, a discharge device, and a measuring device. The control device sets conditions for a recording medium or a process using droplets. The discharge device discharges the droplets onto the recording medium. The measuring device measures landing positions of the droplets on the recording medium. The control device calculates a correction amount based on the landing positions, stores the correction amount for each of the conditions, and correct a timing at which the discharge device performs discharge with correction amounts that match the conditions, to correct the landing positions.
