What should we know about screen printing?
Definition of printing: The method of transferring text/graphics onto a substrate is called printing.
Types of printing: no-printing - such as inkjet, xerographic, laser.
There are printings - such as movable type, offset, and screen printing mesh.
Screen printing is the printing of text/images that need to be printed on a silk screen (now a chemical fiber, mainly polyester fiber).
During printing, the ink reconstitutes the graphic/text on the substrate through the mesh of the mesh.
This is the basic principle of screen printing.
Screen printing belongs to stencil printing, which is called four printing methods together with lithography, embossing and gravure printing. The stencil printing includes a stencil, a stencil, a spray, and a screen printing. The principle of stencil printing is: the printing plate (the aperture of the paper film or other plate is made through the ink). During printing, the ink is transferred to the substrate through the hole of the stencil through a certain pressure (paper, ceramics, etc.) ), forming an image or text.
During printing, the ink is transferred to the substrate through the mesh of the graphic portion by the extrusion of the squeegee to form the same graphic as the original. The screen printing equipment is simple, easy to operate, simple in printing and plate making, low in cost, and strong in adaptability. Screen printing has a wide range of common prints: color oil paintings, posters, business cards, binding covers, merchandise signs, and printing and dyeing textiles.
Screen printing is not limited by the size and shape of the substrate. It can be printed on shaped and uneven surfaces of different shapes. The layout is soft and flexible, and it is the one with the least printing pressure.
Its light resistance is strong: it can put light-resistant pigments and fluorescent pigments into the ink in a simple way, so that the graphic of the printed matter can be kept warm for a long time without being affected by temperature and sunlight, and even can be illuminated at night.
The plate making is convenient, the price is cheap, the printing method is flexible and diverse, and the technology is easy to grasp.
Screen printing process: original → bottom plate → screen version → printing plate → development → drying → printing → drying → finished product inspection → printed matter
