No matter to which kind of printing method, must study its platemaking technology and printing technology.

The screen printing machine selects the plate-making method and printing process and determines the printing material to be used based on the original manuscript. Due to the wide use of screen printing, and the corresponding process types are also many, so choose which process is a very important work. The materials used in each process are also various. The choice of which materials to use depends on the nature of the pattern, the amount of replication, and the use of the product. Take silk screen for example, its materials are now more using nylon, polyester, stainless steel, etc., their process performance is different. Such as nylon mesh with ideal flexibility, recovery and four convex surface can be printed. Polyester screen is used in high precision printing. In addition, according to the different patterns, can also take the oblique stretching network, so that the direction of the network longitude and latitude and the direction of the sub plate to maintain a certain Angle, but also make the network in the tension allowed in the fan

The method of plate - making is roughly hand - cut plate - making and photosensitive plate - making two methods. The former is suitable for imprecise, describable patterns. For printing that requires higher accuracy and emphasizes tonal gradation, the photosensitive plate-making method must be used. In the photosensitive platemaking method, the production of a strong printing plate can be used by the direct method, this method because in the print positive image bottom plate is close to the screen of the photosensitive film, so the image quality is better. For higher quality images, it is better to use the indirect platemaking method.

For printing few, quality requirements are not high, the use of manual screen printing is the most convenient. If the demand is large and a certain quality is required, a high-precision fully automatic printing machine is required. Due to the wide variety of materials, quality and shapes of screen printing, there are many types of printing machines. Screen printing ink due to the different quality of the printing material, ink adhesion performance is different, so you have to choose the appropriate ink. In addition, because the use of the product is different, such as the need for electrical conductivity, corrosion resistance and so on, so the use of ink is different. Because a variety of ink drying methods are different, in use should pay attention to choose the corresponding drying method. At the same time, the substrate of the texture, shape, printing and the use of products, such as the purpose to be clear. Depending on the purpose of use, the accuracy of printed patterns, image quality requirements will also change. For outdoor exhibits, special requirements for weather resistance and durability, etc.
