Document Type and Number:
WIPO Patent Application WO/2023/128173
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an inkjet printing method for preventing smearing by improving, when printing a thick layer of a large thickness through inkjet printing, thickness uniformity while forming a desired thick thickness. In order to accomplish the described objective, the present invention provides a method for forming a thick layer of a thickness (t) on a substrate by using an inkjet printing apparatus comprising a head module for ejecting an ink, the method comprising: (s10) a primary printing step of forming a dot print layer (L1) such that dot-shaped arrays are formed at predetermined intervals in order to prevent ink droplets (d), which are deposited on the substrate, from pulling each other; and (s20) a secondary printing step of ejecting ink in an amount enabling a thick coating of uniform thickness to be overlapped and printed on the dot print layer, thereby forming a thick print layer with the thickness (t).
