Document Type and Number:
WIPO Patent Application WO/2019/073725
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an inkjet coating device that can maintain coating position precision even if the environmental temperature does not satisfy prescribed temperature conditions. Specifically, provided is an inkjet coating device that coats a substrate with ink and is provided with a stage whereon a substrate is mounted and a coating unit having a plurality of heads having nozzles for coating the substrate on the stage with ink, wherein the inkjet coating device comprises a linear scale for a coating gantry and a control device for controlling positioning of the coating unit on the basis of a coating gantry position pulse sequence from the linear scale for the coating gantry and controlling the heads on the basis of ink coating position information, and is configured such that the heads are controlled by acquiring a position pulse correction table for those conditions and generating a corrected position pulse sequence on the basis of the coating gantry position pulse sequence and the position pulse correction table.
