China's paper product finishing technology has been making rapid progress in equipment and materials, and the equipment has been fully automated, on-line production lines, post-print coating, overburden, indentation, and slitting integration, greatly simplifying the packaging and printing. The production process and production costs are reduced, environmental pollution is overcome, and failures such as detachment and delamination are avoided. The production process of paper products for surface modification prolongs the service life of products, expands the consumption space, and makes paper product packaging comparable to plastics and metal packaging, especially in the process of circulation, in order to protect products, disseminate information, and facilitate storage and transportation. It has played an increasingly important role in consumer use and establishing national brands.
At present, there are a wide variety of finishing technologies involving paper products, and there are no uniform formats, models, and standards. This article briefly talks about paper products and their finishing techniques.
First, what is the finishing technology
Paper finishing technology selects different finishing production processes based on different substrates (including no printed graphics and composite molding), and carries out post-press processing from the positioning requirements, forms, and material values ​​of commodity brands. technological design. The general basis is: the use of different substrates (wrapping paper, kraft paper, composite paper, etc.) After prepress, printing and post-press processing for binding, molding, paper container processing, surface decoration and other technologies.
Throughout the paper finishing technology, it has always been inseparable from the printing, sorting, connecting, sewing (glue) box, mounting back, cover and other processing procedures. And almost all must use different finishing techniques to increase the high added value of paper product packaging and printing products.
Second, factors to be considered in the design of packaging and graphic design
As the outerwear of goods, packaging and printing has become an important factor that affects the competition of goods and the share of consumption. For this reason, people have increasingly higher demands on it. They must be low-cost, durable, and aesthetically pleasing; they must ensure that the goods are not damaged, but also stimulate the consumers to use more; they must have anti-counterfeiting capabilities. However, it must be easy to identify signs that are both health and non-toxic, but also able to be recycled - has now become a fashion, packaging and printing industry racking their brains to transform new styles.
The development of packaging substrates has enabled many new materials and technologies to be applied. The upgrading of products has also created new conditions for the development of commodity packaging. It can be simply summarized: Without ink materials, packaging printing (decoration, text) can not be called, and it is even less likely that there will be a civilization history and colorful packaging products; without adhesive material, there will be no different forms of packaging printing Modeling; no coating oil (paint) and film, there is no dazzling array of goods.
We know that color is a factor of change in the comparison process and that reconciliation is a unified factor. At the same time, the color design of packaging, printing, and decorating can't just decorate the picture without text. The unity of decorating and writing often plays a role in beautifying goods and propagating goods. This requires that the color design of the interior decoration should be just right, the screen is gorgeous, the Chinese are not floating, and the harmonious and harmonious beauty is produced. The text design requires rigorous, prominent, concise and scientific ideas. It not only embodies the attributes of the product, but also has strong pertinence, and outlines the artistry and the sense of the times.
Third, the main content of post-press processing
Post-press processing technology, also known as post-printing technology. Strictly speaking: after the printing technology is not a technology, can only be called a method, but in the anti-counterfeiting packaging, due to the different printing locations, will directly affect the anti-counterfeiting effect. Therefore, the author believes that post-printing (anti-counterfeit) is a technology with special significance, because traditional printing will provide opportunities for counterfeiters due to poor management, and secondly, it cannot suppress the activities of criminals from the economic side, and the printing technology is just right. Solve the above two problems.
After the printing carrier is completed, it is often necessary to design the printing process based on the object such as paper container processing or book binding or surface processing (ie, the finishing process of the finishing technology), and in the finishing technology of the paper container, usually Using composite - film - hot stamping - polishing - molding.
