Abstract
Disclosed herein is a process for producing a printed substrate, comprising a step of applying droplets of a liquid containing a material for a desired component to be formed on a substrate to the surface of the substrate to form the component on the substrate, wherein the process comprises, prior to the step of applying the droplets to the substrate surface, a step of subjecting the substrate to a surface treatment in such a manner that the contact angle of the droplet applied with the surface of the substrate falls within a range of from 20° to 50°.
