In the past, corrugated cartons had only been used as a storage and transportation package, and were therefore considered as a rough outer packaging. The surface patterns of the corrugated boxes were mostly lines and monochromatic patterns. However, in recent years, as people's requirements for the packaging of goods have become higher and higher, corrugated boxes have gradually shifted from the simple storage and transportation of the past to high-end sales and packaging. The corrugated cartons with novel designs, exquisite printing, and exquisite appearance not only attract people's attention, but also can increase the added value of the goods and enhance the market competitiveness of the products. However, at present, the overall level of corrugated box printing and processing in China is still relatively low, especially in the selection of processes and related equipment and supporting materials, there are still some misunderstandings. How to improve the printing and processing quality of corrugated boxes is of concern to the industry.
The printing process needs to be improved. Currently, most domestic corrugated cartons use flexo-ink printing to directly perform on-line die-cutting processing; another part uses first-printed face paper, and then confronts corrugated cardboard, and then performs die-cutting on the platform. Processing methods; rare preprints.
Inkjet direct printing + die cutting is the most suitable processing method for “fast, convenient, environmentally friendly, and economical†principle, so it has been widely used both at home and abroad. It accounts for about 95% of the carton processing market in Europe and America, and it also achieves in China. 70%. The cost of offset printing is relatively high, and it is only suitable for a small number of orders with high definition. After the pre-printing of web gravure printing machine, the cylinder can be significantly improved in print definition, the cost is slightly higher, and the production cycle is longer. In Europe, The United States, Australia, South Korea and other countries and regions have some developments, and they are relatively rare in our country.
Comparing with the printing technology that first prints the surface paper and then aligns the paper, the direct printing of the corrugated board has the advantages of high production efficiency, low material consumption, low production cost, large product specification, wide application range, high strength of the carton, neat appearance, and favorable for environmental protection, etc. Superiority is the main process of corrugated carton printing. In particular, with the continuous development and improvement of corrugated box direct color gradation printing technology, the application of direct flexo printing of corrugated boxes will become more and more extensive. In China, the primary printing method adopted for printing plain paper is offset printing. Although it is easy to obtain a more abundant printing effect, the processing method is labor-intensive, and it is only used in the processing of shaped corrugated boxes (boxes). Many, low production efficiency, poor carton molding quality. In foreign countries, more than 80% of color paper cartons are produced by direct printing. In China, color screens are still at the initial stage due to the use of color mesh-aligned corrugated box printing technology. This proportion is much lower and it is far from meeting the needs of market development.
The first printing of paper and then the printing process of the paper is more adaptable to the paper, and it is more applicable to some cartons which require special fine art decoration effects or special cartons with poor water absorption. But in the process of confrontation, the corrugated board will be damaged more or less, and the physical properties such as compressive strength of the carton will decline, which is inferior to the corrugated box directly printed and processed. The use of a flexographic plate direct printing method can complete the entire process of carton processing on a single machine. The processed carton or carton is processed to reduce the positioning error of the paperboard caused by the process change, the processing precision is high, and the production efficiency is high. The low production cost is definitely the development direction of corrugated carton printing and processing.
Equipment consumption village carefully selected on the corrugated board printing is the development direction of corrugated box processing, this point is no doubt. However, to adapt to the development trend of color printing and screen printing, reasonable allocation and selection of equipment consumables plays an important role.
At present, corrugated box manufacturers in China can be roughly classified into three categories according to the characteristics of their equipment. One is a number of individual cartons. The scale of operation is relatively small. Most of them are still using relatively backward single-machine manual operations, with obsolete equipment and low production efficiency. Poor product quality is the object of elimination. The second is a leading part of the carton backbone enterprises. Its main equipment is domestically-made advanced equipment, with a high degree of automation and high production efficiency. The third is a small number of powerful wholly-owned or joint venture companies. They have introduced advanced corrugated board printing slot machines, die-cutting machines and other equipment to make corrugated paper from companies such as Emba in Sweden, Martin in France, Kiel in France, and Langston in the United States. Box production line, high degree of automation, high production efficiency, product quality is also high.
In recent years, some of the domestic carton printers have introduced some printing slot machines from abroad or Taiwan due to quality and efficiency considerations. However, this type of equipment is required to achieve rated productivity and processing quality, and to meet the quality requirements of corrugated boxboards. Both are relatively high and there are certain requirements for the ink. In fact, many home-made high-quality printing slot machines adopt a lot of new technologies, new processes, and adopt computer control, which not only has high production efficiency, but also because the design is closely integrated with national conditions, so not only the price is cheaper, but also the adaptability is higher. Strong, should be the majority of domestic carton processing using boxing, but with the increasingly stringent requirements for packaging, nail rust will not allow contamination of the contents, the need for refrigerated goods is even more so, so the sticky box will be The future direction of development.
In addition to equipment factors, the rational choice of anilox rollers, the promotion of the use of large mesh ceramic anilox rollers, the use of appropriate thickness plates and white elastic liners, and high-quality inks are also necessary to improve the printing quality of corrugated boxes. Indispensable.
Speaking of the major problems existing in the selection and use of corrugated boxes for printing and supporting materials by domestic corrugated box users, the general situation is that there is a large market for corrugated boxes in China, and there are also many manufacturers of corrugated boxes, but manufacturers who can produce good products are able to process them. Not much. An important reason for this is that there are no problems in solving the process and supporting materials from improving the quality of the printing process. No matter what type of machine is used, it is difficult to achieve the goal of improving quality if it does not pay attention to its quality and function when selecting supporting materials. The role of printing matching materials in the entire carton production is critical. If you do not use matching materials that can improve print quality, this is not only a waste of materials, but also a waste of equipment resources. There is a causal relationship between the production input and the benefits of the product. The key is to see how to handle it.
The R/bak pad type lining plate that we provide for domestic users now is a kind of professional printing pad, and it has been widely used in the world. Due to its open-celled microporous structure, it does not close the air inside when it is compressed, and it can provide a constant resilience, so it can compensate and buffer printing pressure. It can be used together with thin resin printing to avoid printing. The expansion of the outlets and the phenomenon of white space on the ground, applied to different grades of corrugated box printing presses, can significantly improve the printing quality. For net board and field printing, the effect is even more pronounced. However, due to its high price, when it was recommended to users in China, it had encountered the problem of increasing costs and whether it was worth investing. After our work in recent years, at present, the application of R/bak liners in China has gradually become popular, and the market is also well-received. The main reason is that the effect is obvious after users use it, which improves the printing quality and brings new business. R/bak pads have a long service life and have more technical and quality advantages than non-professional pads. Some carton printers have improved the quality of their domestic and old equipment after using R/bak liners, and the printing has been upgraded; some imported equipment has already been supplied with R/bak liners from the factory; many domestic Carton equipment manufacturers are also working with us to use R/bak pads as standard equipment. For the cleaning and maintenance of the anilox roller, we also encountered the same problem. After some problems encountered by the carton factory, the ink and plate issues first thought of came into contact with the ink supplier and the plate maker. The problem could not be solved. Finally, we found the solution to the problem from the cleaning and maintenance of the anilox roller. At present, many large-scale carton factories in China are provided with cleaning technologies and products, which have changed the habit of not paying attention to the anilox roller cleaning. However, in the small and medium carton factories, the phenomenon of neglecting the cleaning and maintenance of the anilox roller is still widespread, and it is necessary to change the concept.
Corrugated carton proofing is also often overlooked by domestic carton manufacturers. At present, carton proofing mainly includes the following methods: proofing on printing presses, proofing on proofers, traditional film proofing and digital proofing. The proofing on the printing press is actually printing, and the cost is higher due to the use of printing inks and officially printed substrates, equipment, and consumables. Proofing on proofers currently uses offset printing, which is usually done on paper instead of on corrugated cardboard. The proofs cannot represent the actual effect of direct printing on white corrugated boxes, and the equipment and consumables required are very expensive. Very high. The most used traditional proofing program in the industry is Cromarin proofing. Usually, several sets of film are made for proofing. The arrival of the digital era has brought about the digitization of proofing, but at present, the carton industry rarely adopts digital proofing, because this new technology is not well known, proofs do not have printing outlets, and printers hope to see outlets on proofs. In order to determine how to print, in addition, digital proofing is not performed on official substrates and does not represent true printing effects. (Unfinished) (Soundstar News)
