Curved silk screen printing method

Abstract

The invention discloses a curved silk screen printing method. The curved silk screen printing method comprises the following steps of arranging a printed piece a rotatable working table under a silk screen; adjusting the angle of the working table and adjusting the relative positions of the working table and the silk screen to enable one end of a curved surface of the printed piece to make full contact with and be tangential to one end of the bottom surface of the silk screen; driving an ink scraping blade to squeeze the silk screen carrying printing oil and move from the end, making contact with the printed piece, of the silk screen to the other end; and meanwhile, driving the working table to rotate and adjust the relative positions between the working table and the silk screen to ensurethat the printed curved surface of the printed piece makes contact with and is tangential to the silk screen all the time in the rotating process of the working table and ensure that the contact point of the silk screen with the printed curved surface moves along with the ink scraping blade synchronously. Through the curved silk screen printing method provided by the invention, printing ink can gradually penetrate through the silk screen to complete printing along the contour of the curved surface to achieve the effect similar to plane printing, and thus, the application range of silk screenprinting is wider.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a curved screen printing method. Background technique [0002] Screen printing technology refers to the use of screen as the plate base, and the photosensitive plate-making method to make a screen printing plate with graphics, and then print the pattern or text on the screen printing plate on the substrate; screen printing It is often used for the printing of flat substrates and the printing of rotary curved substrates; and, at present, there are flat and curved screen printing methods for printing on flat surfaces, and curved surface screen printing machines for printing on rotary curved surfaces, but for non- The substrates with convex surface in the rotary curved surface cannot be printed by screen printing for the time being. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For...
