Title: Screen printing method
Inventor: SAKAI MASAHIRO
IPC: B41M1/12
Filed: 1990-02-19
Abstract: PURPOSE:To remarkably reduce the expansion/contraction and distortion of an image part to improve a printing accuracy by a method wherein a screen printing is made using a plate in which a part from a printing start-side plate frame part of a non-image part of a printing plate to a printing finish part in the vicinity of an end of the image part is hard in comparison with the other parts. CONSTITUTION:A highly-hardened emulsion film is uniformly formed all over a screen 2 set on a plate frame 1. A non-image part 4 using the hard emulsion is formed by developing. Thereafter, on a part where said emulsion is removed by developing, a conventional emulsion film is uniformly formed, and a non- image part 5 and an image part 3 using the conventional emulsion are formed by developing. When a screen printing is made using this plate, the image part 3 is dimensionally fixed by the non-image part 4 made of the hard emulsion, therefore being little affected by a printing pressure by a squeegee 6 and a tensile force. Thus, an image pattern 8 printed on a printing medium is expanded/contacted and distorted from an image 8 on the film and the plate to a very small extent, therefore being enhanced in accuracy.
