Film is not covered?

Recently, some businesses have advocated the useless film theory, saying that the film technology is out of date because the printed materials they produce can be pre-coated to prevent UV radiation, and UV protection agents can also be added to ink and paper. Need to cover film. In the end there is no cover film? Let us listen to the opinions of experts. “The reason why merchants say this is purely for sales.” Some people think: “It's easy to understand that no printer seller will be stupid to say, 'You buy my product, you must buy another laminator after you buy it.' '". Others think that those people do not understand the film at all, but they make comments. "They are not fish, know how to fish music?" may be the best advice for them. So what's the benefit of coating? Film can provide protection for images. The most undeniable fact at present is the protective effect of the film. Whether it is wear-proof, waterproof or UV-resistant film, their functions are incomparable with ink and paper. Especially for those works that need to be displayed, I do not know how many times they must be handled, handled, moved or moved. Only the film can effectively prevent scratches, scratches and other mechanical damage. Film can improve image quality. For matte work, the adhesive in the film can penetrate into the voids of the toner and reflect the finest colors, which increases the color depth of the image. For bright works, it can also reduce the degree of surface reflection of the printed products, and protect the human eye under the premise of obtaining the maximum color depth. Laminating is also good for sales. The truth is very simple: Safflower has greenery. We have known the story of “Buying and Returning the Pearl” very early. That is to say, a person spent money to buy a beautiful box with jewels, but returned the gems to others. The story illustrates the truth from the side: Exquisite packaging does add color to the product, stimulates people's desire to buy, and sometimes even makes people mistaken for value than the product. Film can save costs. Despite the appearance of waterproof paper and waterproof ink, their price is double that of film. And the effect is not as laminating. Of course, although there are many benefits to laminating, only the best way for you can be truly beneficial. There are many ways to cover the film, but the most common and basic method at present is only cold (cold pressure) and heat (heat live). The hot film technology refers to the process of heat activation of the pre-coated adhesive on the film, and the process of bonding the film and the printed product together; and the cold film is pressed directly, and the film directly adheres to the adhesive. The prints are glued together. Both methods can produce special films such as UV protection film, waterproof or anti-friction film. Recently, there has also emerged an emerging technology called the "liquid coating" method. The transparent liquid is brushed directly on the surface of the product with a brush, a spray gun, a roller, or a special laminator. This method is simple and costly, but it is not yet mature. When choosing a laminating device, in addition to the above problems, other aspects should also be noted. Such as whether it can be installed, temperature range, mode and cost. In general, the more high-end machines provide more functions, but the price is higher. Obviously, the lamination technology will not be outdated for quite some time to come. In particular, the emergence of digital images and the application of huge outdoor advertising, they all need the support of lamination technology. The film will always exist, whether or not there is UV protection printing substrate.
