Screen printing method and imprinting apparatus

A screen printing method, comprising:

• providing at least one printing scraper assembly, wherein the printing scraper assembly comprises a printing scraper and a pressure sensing feedback system;
• placing at least one printing screen on a substrate;
• detecting, by the pressure sensing feedback system, a pressure value between the printing scraper and the printing screen during printing, and supplying, by the pressure sensing feedback system, the detected pressure value to a control device;
• and
• comparing, by the control device, the supplied pressure value and a predetermined pressure value, and changing, by the control device, a pressure between the printing scraper and the printing screen if a difference between the supplied pressure value and the predetermined pressure value is larger than a predetermined threshold,
• wherein the substrate comprises first and second printing regions and a non-printing region between the first and second printing regions,
• wherein the method further comprises during the printing:
• moving, by the control device, the printing scraper on the printing screen to pass through the first printing region, the non-printing region and the second printing region successively,
• wherein the printing scraper, when passing through the non-printing region, is controlled by the control device to be moved away from the printing screen in a first direction perpendicular to a plane where the printing screen is located so that the pressure between the printing scraper and the printing screen in the non-printing region is smaller than that between the printing scraper and the printing screen in the first and second printing regions,
• wherein the at least one printing scraper assembly comprises a plurality of printing scraper assemblies, and the pressures between at least two printing scrapers of the plurality of printing scraper assemblies and the printing screens are different in different regions.
