Abstract: A liquid discharge apparatus includes a liquid discharge unit, a position detector, and circuitry. The liquid discharge unit has a liquid discharge port and discharges a liquid from the liquid discharge port toward an object. The position detector detects a position of the liquid discharge unit relative to the object. The circuitry calculates a movement trajectory of the liquid discharge unit based on the position of the liquid discharge unit detected by the position detector. Further, the circuitry performs a first operation of causing the liquid discharge unit to move along the movement trajectory without discharging the liquid and performs a second operation of causing the liquid discharge unit to move along the movement trajectory while discharging the liquid to the object after the first operation.

Abstract: Disclosed are a method of filler taping a screen frame and a method of filling a screen frame. The screen frame is held in such a manner as to be indexable 90 degrees, a tape is attached simultaneously on opposing two sides of the screen frame through linear motion. At the same time, a filling liquid is applied simultaneously on opposing two sides of the screen frame on the rear surface thereof. Subsequently, the screen is rotated 90 degrees, and taping and filling are similarly effected with respect to the remaining two sides.
