There are four types of printing: flat printing, convex printing, concave printing, and screen printing.

The common method of flat printing is to print paper; Convex printing and concave printing, to put it simply, seals are both used; And screen printing covers a wide range of printing options, which can print the vast majority of the first three substrates. It is also common. Although we are not very familiar with it, if you look around, such as the letters on the keyboard, the text on the monitor, the patterns on T-shirts, the images and texts on containers, etc., all are printed using screen printing.

Silk screen printing, also known as silk screen printing, refers to carving a silk screen plate and then printing. PEEMBOSS refers to carving a copper mold first. If the pattern is of one color, pour the rubber material in and then come out. If it is of multiple colors, it is slightly more troublesome. Screen printing process: original manuscript → bottom plate → screen plate → printing → development → drying → printing → drying → finished product inspection → printed product.

Screen printing is actually a form of screen printing. Simple screen printing involves using a screen (very dense) to stretch it onto a frame, applying photosensitive adhesive, and then outputting the images and texts that need to be printed using sulfuric acid paper laser. The images and texts that need to be printed are placed under the screen and exposed to an exposure lamp for a few minutes. Then, using water bubbles, the parts that need to be printed do not have photosensitive adhesive, while other parts that do not need to be printed still have photosensitive adhesive, that is, ink leakage and no ink leakage, Blow dry to start printing. This method is manual printing. If mastered, print something simple, such as umbrellas, T-shirts, finished calendars with lettering, cylindrical containers, flat metal, etc.

Screen printing is not limited by the size and shape of the substrate, and can be printed on different shapes of molded materials and concave convex surfaces. The layout is soft and elastic, making it a type of printing with low printing pressure.

The screen printing method has thick ink application and strong adhesion. Printing thickness can reach 30-100 μ m. The covering power of ink is particularly strong, and the three-dimensional sense of printed images and text is unparalleled by other printing methods (the thickness of the ink layer can also be controlled). Screen printing is suitable for various types of inks: it has strong adaptability and can be used for printing with any type of coating, such as oil-based, water-based, synthetic resin type, powder and other inks. Ink and paint that can penetrate the mesh fineness of the silk screen can be used. It can be printed in single colors, as well as color printing through color matching and screening.

It has strong light resistance: it can easily put light resistant pigments and fluorescent pigments into ink, keeping the printed images and texts shiny and not affected by temperature and sunlight, and even emitting light at night. Easy plate making, cheap price, flexible and diverse printing methods, and easy to master technology.
