No matter what kind of printing, the Printing Process is the initial stage of the whole. Screen printing is no exception. At the same time, print and products for substrate quality, shape and purpose are needed to clarify the. According to the purpose of use, the accuracy of printing patterns, image quality requirements will also change. For outdoor exhibits will be particularly required for its weather resistance and durability, etc..
Screen printing is based on the original, the choice of plate making method and printing process and determine the use of printing materials. Due to the use of screen printing is very wide, so there are many types of the corresponding process, which is a very important work. Materials used in various processes are also varied, the choice of what kind of material to be used according to the nature of the pattern, the amount of replication, the use of the product. For example, the screen, for example, now more than the use of nylon, polyester, stainless steel, etc., the process performance is different. Such as nylon mesh with ideal elasticity and resilience, as well as concave convex surface can be printed features. In the requirements of high precision printing, the use of stainless steel wire mesh. In addition, according to the different patterns, but also can be taken oblique method of tension, so that the line of latitude and longitude of the network and the direction of the scraper to maintain a certain angle, but also allows the network to allow tension within the tension, relax.
The method of plate making is roughly two methods of engraving plate and photosensitive plate making. The former applies to the accuracy is not too high, the pattern can be described; the need for high precision, and emphasize the level of color printing, you must use the photosensitive plate method. In the photographic plate, making strong printing resistance plate can be used directly, since this method is in print, Yang figure deban close to the photosensitive film screen version, so the image quality is poor, need high quality image, the best use of plate method.
To print, do not require high quality printing, use the most convenient manual printing. If you need a large amount and require a certain quality, you need to use high-precision automatic printing machine. Due to the screen printing materials, quality, shape vary widely, so there are many types of printing presses. Screen printing ink, because of the different texture of the printing material, ink adhesion performance is different, so there must be targeted to choose the right ink. In addition, due to the use of different products, such as the need for electrical conductivity, corrosion resistance, etc.. So the use of ink is also different. Because of the different methods of drying ink, in use should pay attention to select the appropriate drying method.
As mentioned above, Screen Printing Process is complex and varied, in many ways how to choose the most appropriate method, you need to have a wealth of technical knowledge. It can be envisaged that the future screen printing applications will be more extensive, more diversified. With the further reform of machine and material, more, newer, better quality and more characteristic products will be produced. But in any case, the basic technology of screen printing will not change.
