Method of controlling image resolution on a substrate using an autophobic fluid

摘要

A method of controlling the resolution of an image formed on a substrate comprises: (a) providing a substrate; (b) applying an image to the substrate by ink jetting onto the substrate a fluid composition comprising at least one surfactant, wherein the spreading of the fluid composition on the substrate in the presence of the surfactant is less than the spreading of the fluid composition on the substrate in the absence of the surfactant. The invention reduces the dot spreading which otherwise occurs when a substrate is imaged via ink jetting to prepare a printing plate.
