Embodiment Construction

[0030] Water-based varnish continuous adjustment screen printing process, including the following steps:

[0031] 1) Make continuous tone image files: design and produce continuous tone image files with rich and clear layers in Photoshop image processing software;

[0032] In the image processing software Photoshop, open the original color image, under the image menu, change the mode from color image to grayscale image, then press Ctrl+M to open the curve dialog box, adjust the image, and pull the image layer to make the image layer More abundant reproduction; the requirements for continuous tone manuscripts are: the contrast of continuous tone manuscripts should be larger, and the light and shade levels from highlights to dark tones should be rich, clear and vivid;

[0033] 2) Making film: Due to the limitations of its plate making method and screen material, a laser phototypesetter (the laser phototypesetter adopts Screen 5055 laser phototypesetter) is used to output the fil...

Abstract

The invention belongs to the technical field of printing and particularly relates to a continuous adjustment screen printing process of water-based gloss oil. The continuous adjustment screen printing process comprises the following steps of: 1) manufacture of continuous adjustment image files; 2) manufacture of films; 3) cleaning of the films; 4) stretching of a screen; 5) gluing; 6) positioning of the films; 7) exposure; 8) development; 9) drying; and 10) screen printing. The continuous adjustment screen printing process has the advantages that 1) the wear resistance is strong, the scratching is resisted, the screen-printed surface is wear-resistant, water-repellent and oil-repellent, and no color-fading phenomenon occurs on the surface of a printed product; 2) the film forming speed is fast, and the drying is rapid; 3) the high temperature resistance and the hot-sealing performance are good; 4) the degree of planeness is good, and the winding force resistance is strong; 5) the used water-based gloss oil has better leveling property, can realize fast leveling before a coating layer is dried to form a smooth surface, so that the coating layer can have high glossiness; and 6) the water-based gloss oil adopts water as a solvent without toxicity and smell. Compared with the water-based gloss oil used for local glossing, the continuous adjustment screen printing has the advantage that the image layering can be reproduced.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a water-based varnish continuous modulation screen printing process. Background technique [0002] Screen printing is through the extrusion of the scraper, so that the ink is transferred to the substrate through the mesh of the graphic part, forming the same graphic as the original. At present, with the sharp increase in the demand for screen printing, continuous tone screen printing also enjoys a high reputation in the industry, but most of the continuous tone screen printing process uses ink for silk screen printing, and the products after silk screen are easy to fade, However, there are disadvantages such as poor wear resistance, so it is urgent to develop a new screen printing process to solve the above problems. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical sc...
