Coating printing method and equipment

The invention belongs to the technical field of coating printing, and discloses a coating printing method and equipment. The coating printing method comprises the steps that a printing head is controlled to spray a solution to a base material, and the base material is controlled to move relative to the printing head, so that the solution forms a liquid film on the surface of the base material; the thickness of a liquid film is obtained, and after the thickness of the liquid film meets the requirement, annealing treatment is conducted on the base material; and carrying out quality detection of ultraviolet-visible spectrum analysis on the liquid film of the base material while carrying out annealing treatment, and finishing coating and printing of the base material when the quality of the liquid film meets the requirement. Therefore, when the liquid film is formed, the quality of the liquid film is detected in real time, when the quality of the liquid film is found to be unqualified, corresponding adjustment ca
