With the development of society and the continuous improvement of people's living standards, when consumers purchase commodities, in addition to the intrinsic quality of commodities, the packaging of commodities also puts forward higher requirements. This includes not only the requirements of packaging design, but also the quality requirements of packaging processing after printing. Local compaction of printed materials produces traces that give them a certain degree of concave and convex space called indentation.
Initially, indentation technology was only used for carton packaging, but later it was gradually applied to the surface processing of various printed products, especially high-grade cartons, cartons, trademarks, crafts and other surface finishing. Now, indentation technology has become one of the important means of packaging design. It not only plays an important role in the final quality and packaging, but also greatly improves the artistic effect of printed matter and makes the new function of printed matter become an important means of value-added and promotion.
The indentation line is a process of indentation of steel wire through indentation on the substrate, leaving a good impression on the bending groove. The main reasons for irregular indentation line are that the left of indentation groove of steel wire pad is too wide and the position of indentation plate is not fixed; the thickness of steel wire pad is insufficient, the groove angle is not standardized, and there are redundant rounded corners; the tightness of knife row and fixed knife is inappropriate, the steel money is too tight, the bottom can not reach the flat surface of the indentation plate, and the steel money is easy to twist when indentation is too loose; The indentation is easy to move. The elimination method is to replace the steel wire pad with appropriate width of indentation groove, increase the thickness of the steel wire pad and trim the groove angle, adjust the position of the template, and use hand knife for many times to feel the appropriate tightness.
Some products require large indentation area and process requirements will become embossing. Some products have post-press indentation, some have post-press indentation, and some have diversified methods when printing film indentation. The concave-convex and indentation are often completed at the same time. Die-cutting indentation technology also plays a very important role in cigarette label packaging, because it directly affects the quality of cigarette label packaging, and can meet the requirements of cigarette machine in cigarette factory. Ultra-large-scale production of packaging boxes, such as cigarette and wine labels, is usually mass production, repetitive production, to ensure product quality, under the premise of concave-convex, die-cutting indentation technology to complete the production of cigarette labels, not only for the company to save machinery and equipment investment, but also can greatly improve production efficiency. The indentation technology is more widely used. Thick paper folding, invitation cards, tickets, greeting cards, color laser printing, ink-jet printing, coupons, tickets, receipts and other traditional applications are more in-depth, while in wine boxes, advertising, folding business cards and other new areas are widely involved.
Generally speaking, in the process of packaging, we need products that are suitable for consumers'needs and habits. In short, the improvement of living standards requires that the quality of our cartons not only be at the level of hardness, compression and other technical qualifications, but also at the beautiful ornamental level. It also requires that our indentation technology continue to surpass and provide more and better products for the people. This is our traditional idea.
