Outdoor advertising is a strategic choice for a company to establish brand concept and maintain corporate image. It is a systematic and unified method to convey brand concept to target customers, establish brand confidence and improve corporate visibility. Outdoor advertising should not only be attractive and produce unforgettable and psychologically acceptable effects, but also well-made billboards should include good painting effect and stretching performance. Lack of strength, shock and contrast will not convey the design concept, so it will greatly reduce the influence of advertising. Unfortunately, many external factors will destroy the concept of design and creation. Climate, sandstorm, ultraviolet rays, pollution, bacteria, dust, artificial lighting, etc. Will pose a threat to billboards. If the performance of the ink used in inkjet printing is unstable, or the ink absorption of advertising consumables is poor, the advertisement will change color under the influence of external factors such as ultraviolet rays, dust and pollution. Moreover, if the strength of the silk is not enough and the structure is not good, the outer surface of the cloth may be damaged, torn or deformed under the combined action of wind and sand or other external factors, and PVC may also peel off from the base cloth. Because billboards inevitably bear the above threats, today's advertising experts not only attach importance to the design and painting quality of advertisements themselves, but also take a very cautious attitude in the production and material selection of billboards. In this way, the choice of advertising inkjet cloth has played a decisive role. Even if the actual creativity of the advertisement is ingenious, the quality of the painting is very good, and the exhibition place is excellent, all these efforts may be in vain if the consumables are not among the "precise selection". Call the advertising market, there are all kinds of low-priced calendering cloth, different types of inkjet cloth, roller coating with better quality and lower price, and the top part of the pyramid is knife-coated cloth. Blade coating technology has the outstanding characteristics of stabilizing advertising effect and transmitting effective information to consumers. Different quality grades of inkjet cloth come from different raw materials. For example, the thickness of silk and whether it is high strength silk are all very important factors. There are many ways to make PBC, and different chemical elements will also affect the properties of fabric such as ultraviolet resistance, mildew resistance and thermal deformation. Coating auxiliary transparent acrylic paint on PVC coating is also one of the options, which can protect PVC coating. It is precisely because of the adoption of different technology that the use effect itself has corresponding differences. Obviously, the peeling strength of calendering materials can not be compared with that of scraper materials. The coating technology itself determines the best bonding degree between PVC and polyester yarn, because in the manufacturing process, liquid C is added with specific additives, which makes C firmly bonded to the base fabric. However, in the process engineering of calendering soft sheet PVC film on base cloth, this is impossible. Another notable feature of the blade coating technology is the high silk content and compact structure of the fabric. Even if it is used in extremely harsh environment, the finished product still has high quality.
