Description

Compound printing half tone

Technical Field

Background

The silk screen printing refers to that a silk screen is used as a plate base, and a silk screen printing plate with pictures and texts is manufactured by a photosensitive plate making method. The screen printing is composed of five major elements, namely a screen printing plate, a scraper, organic slurry, a printing table and a printing stock. The basic principle that meshes of image-text parts of a screen printing plate can be permeated by organic slurry and meshes of non-image-text parts of the screen printing plate can not be permeated by the organic slurry is utilized for printing. When in printing, organic slurry is poured into one end of the screen printing plate, a scraper is used for applying certain pressure to the organic slurry position on the screen printing plate, meanwhile, the organic slurry moves towards the other end of the screen printing plate at a constant speed, and the organic slurry is extruded onto a printing stock from meshes of the image-text part by the scraper in the moving process.

The screen printing is one of the key steps for preparing the solar cell, the printing screen plays a crucial role in the screen printing quality, and generally comprises a rectangular screen frame and printing screen cloth tensioned and fixed on the rectangular screen frame. The printing screen cloth is provided with a pattern area and a non-pattern area, wherein the pattern area only comprises a metal screen, and the non-pattern area comprises the metal screen and emulsion attached to the metal screen. When the printing screen is adopted for printing the solar cell, the slurry can permeate through the metal wire mesh holes in the pattern area of the printing screen cloth, but cannot permeate through the non-pattern area, so that corresponding patterns are formed on the surface of the cell, and the manufacturing of structures such as a cell surface electrode is realized.
