Embodiment Construction

[0013] Preferred embodiments of the present invention will be described in detail below.

[0014] A screen printing method is characterized in that, comprising the following steps:

[0015] 1) To make the screen, the first coating of photosensitive glue and the second coating of photosensitive glue are carried out successively on the screen, and each time the front and back sides need to be coated, the back is first coated, and then the front is coated. After the photosensitive glue is coated for the first time, the first drying is carried out. The temperature of the first drying is 30°C, and the first drying time is 35 minutes; The second drying temperature is 40°C, and the second drying time is 20 minutes;

[0016] 2) Use the scraper of the screen printing machine to print the ink from the hollowed out part of the screen onto the paper;

[0017] 3) Send the paper printed with ink into the heating oven for heating to make the water-based foaming ink foam. The oven temperatu...

Abstract

The invention discloses a screen printing method. The method comprises the steps of 1) manufacturing a screen printing plate; 2) printing paper; 3) heating the paper; 4) naturally cooling the paper. With the adoption of the method, the actual problems of loose photo-sensitive resist, pasting to plate, non-uniform and unstable ink coloring, deformation of ink patterns, bubble marks, screen marks, irregular edge holes, needle pores and screen blocking in actual printing can be effectively avoided; the printing quality can be obviously improved, and the practicability is high.

Description

technical field [0001] The invention relates to the field of printing, in particular to a screen printing method. Background technique [0002] The screen printing process is well known, such as Chinese invention patent CN201210405827.1 disclosing a new process of physical fine anti-dyeing of traditional blue calico, the blue calico production process includes the following steps: pattern design: design according to the printing pattern requirements Pattern; pattern black and white draft production: process the designed pattern into black and white draft reverse film; screen printing plate production: tie nylon screen with wooden frame printing plate or square steel frame printing plate, apply photosensitive glue, and carry out in darkroom Photosensitive, and then save the firm part after photosensitive, and rinse off the opaque part with water; thicken the anti-staining layer of the pattern: use raw lacquer or alkyd varnish to dry three times to form a paint film, and the p...
