Title:
INKJET PRINTING METHOD AND INKJET PRINTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/128172
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an inkjet printing method by which stains can be prevented from being generated, by improving the uniformity of thickness while achieving a large thickness intended when a thick film layer is printed by the inkjet printing method. In order to solve the described problem, the method for forming a thick film layer having a thickness (t = t1+t2) on a substrate by using an ink jet printing apparatus including a head module for discharging ink, comprises: a first printing step (s10) of forming a thin film printing layer having a thickness (t1) on a substrate by discharging ink in an amount in which a thin film coating of uniform thickness can be printed by attraction of ink droplets that land on the substrate to each other; and a second printing step (s20) of forming a thick film printing layer having a thickness (t2 = t-t1) by discharging an ink in an amount in which a thick film coating having a uniform thickness can be printed by overlapping on the thin film printing layer.
