[Carton Printing Machine] Experience Exchange: How to Choose Carton Printing Machine

Exchange of experience: How to choose a carton printing machine With the continuous progress of printing technology, the varieties of printing machines on the market are diversified, and some equipment structures also have some post-processing production functions. It can be said that the manufacturing technology of printing machine is becoming more and more mature, which greatly promotes the printing quality and production efficiency of products and reduces the consumption of printing production. Because of the different types of printing equipment, their uses are also different. The printing machine used in carton production must conform to the characteristics of carton products and printing production technology, so as to better meet the production requirements and improve economic benefits. There are many types and structures of carton printing machines, including gravure printing machines, flexographic printing machines and planographic printing machines suitable for preprinting carton paper, as well as multi-functional models that can finish glazing, hot stamping and screen printing online, including roll paper structures and flat paper models. There is also a flexographic printing machine, which is suitable for directly printing corrugated board and can complete slotting, corner cutting, cutting and indentation online. Carton preprinting equipment means that before pasting tissue paper (such as kraft paper board or white board) on corrugated board, the graphics and texts on the box are preprinted in the position corresponding to the tissue paper with a printing machine, then the printed tissue paper is pasted on corrugated board, and then die-cutting and indentation molding are carried out with a die-cutting machine, thus making a complete finished carton. This machine is characterized by high printing production efficiency and high printing accuracy, and is more suitable for printing high-grade color corrugated boxes for food packaging such as beverages, beer and electronic equipment. Semi-finished products printed by pre-printing equipment with web structure can be directly installed on tile line to form corrugated board. Because there is a certain heating time when making, the strength of corrugated boxes can be improved by using this equipment. Flexographic printing machine suitable for corrugated board printing, printing on the uneven surface of corrugated board. The quality effect of graphic ink printed by it is obviously not as good as that of preprinting equipment, especially not suitable for printing products with fine dot quality. Therefore, this machine is generally only suitable for middle and low-grade carton products with rough graphic typesetting. The basic principle of purchasing carton printing machine: the selection of carton printing machine should proceed from the principles of economy, technology and applicability to better improve the economic benefits of enterprises. The so-called economy means less equipment investment, large equipment utilization space, fewer machine operators and low production cost, which is the basis for improving economic benefits. From a technical point of view, products with fixed layout, large printing volume, large printing area and thick ink layer should be printed by gravure press, which is conducive to improving the printing quality and production efficiency of facial paper. Lithographic printing machine can be used to print products with rich colors, large graphic printing area, colors composed of dots and products with uncertain printing quantity in each batch. For products with rough surface paper material, simple line version, lax ink color requirements, frequent changes in local characters and patterns or repeated printing, and carton products with simple die-cutting and indentation layout, you can choose flexo printing slotting machine to directly print corrugated board and cut, corner-cut, notch and indentation online. Applicability means that the type of printing machine you choose should be suitable for the product structure characteristics of our factory. For example, carton products with various structures, large factories can have gravure, lithography and flexographic printing machines at the same time. This can greatly improve the comprehensive utilization rate of equipment, production efficiency and printing quality of products. Generally speaking, carton enterprises must be clear about the production direction of their own factories when purchasing printing machines. That is to say, before buying a machine, you should first know your own product characteristics and accurately understand the performance and characteristics of various printing machines, so as to correctly decide which model to buy and which auxiliary equipment or devices to configure, so that the purchased equipment can give full play to its due role. Several factors should be understood and mastered when purchasing printing presses: the correct selection of printing presses is related to the production efficiency and product quality of factories. After all, equipment procurement is different from raw materials. Once the machine is put into use, it cannot be returned. If you don't know the market accurately and buy printing equipment blindly, after a period of use, even if you have discovered the shortcomings of the machine and the characteristics that are not suitable for our products, it will be too late. Therefore, we must be cautious when purchasing printing machines. First, we should carefully examine the market situation, timely understand and master the latest technical trends, and know what kind of products need what kind of printing machines, which is conducive to improving production efficiency and quality and reducing consumption and production costs. This is the most important factor that should be considered. Therefore, when purchasing a printing press, we should pay attention to the following aspects: understanding the performance and use of the machine is a very important purchasing knowledge, and it is also a key link related to whether the selected printing press is suitable for the product characteristics of our factory and ensures low input and high output. Therefore, before purchasing equipment, it is necessary to conduct careful investigation and understanding through careful consultation and in-depth market, so as to accurately understand the actual performance and accurate use of the printing press. Market research is not only a simple visit to the equipment factory, but also to the relevant carton factory and printing machine factory to understand the actual performance and situation of the printing machine, so as to understand more accurately and better avoid one-sidedness and blindness in procurement. Understand the technical performance of printing machine. Various printing machines have requirements on technical performance, requirements and scope of application. Therefore, it is necessary to know the relevant technical requirements of printing presses when purchasing, so as to make reasonable selection and acceptance according to the standard requirements, so that the selected printing presses can better meet and meet the requirements of equipment performance and production. The technical requirements of the printing machine mainly include the specifications of the machine, the maximum and minimum printing widths, the thickness of the printing material, the overprint accuracy, the machine speed, the motor power and so on. This must be clearly understood. Choosing a printing machine with the right price determines the production cost, so we should get rid of the misunderstanding that "a good printing machine must have a high price" and "cheap goods are not good". In fact, due to the differences in production management level, production scale and regional economy, the printing opportunities of the same type have certain price differences, and even some factories produce printing machines with advanced performance, but the price is lower than other factories with average performance. Therefore, when purchasing, we must pay attention to multi-party understanding, inspection and comparison, so that the production capacity and product printing quality of the selected printing machine can be well guaranteed and the price of the machine can be reasonable. According to the actual situation of the factory, determine the variety and quantity of printing machines and the configuration of machines. The so-called machine configuration refers to some production functions and devices of the printing machine structure, such as the number of printing units, online configuration of polishing, die cutting, hot stamping and other units or devices. The configuration of the machine should consider the characteristics of the production process. For example, in terms of the characteristics of flexographic printing process, it is obviously different from lithography and gravure printing process. For example, for products with the same color, there are both solid and small characters, lines and grids. As long as a printing plate is made with one color group, the printing quality can be satisfied. If the flexographic printing process is used, a page must be divided into two editions and printed with two color groups. Therefore, if we choose flexographic printing, we must consider the reasonable number of color groups. However, if pre-printed carton paper, cartons and other packaging printed products are the main products, polishing, die cutting, hot stamping and other processes are often essential, so it is necessary to consider configuring drying devices and units with corresponding functions. Reasonable selection of machine specifications The specifications of the printing machine are related to the size of the printing format, and a large machine printing area means high production efficiency. The unfolded size and width of large and medium-sized carton products are generally above1000 mm. Therefore, on the one hand, the width of machine printing should be above 1000mm to meet the production requirements of carton products; On the other hand, the commercial competition in the carton industry is fierce now, and the situation of low printing profit is increasingly prominent. Some printing houses aim at improving the printing format. For some products with large batch, imposition printing is often adopted to reduce production consumption and production cost and improve printing efficiency and production efficiency. Pre-printed carton products, mainly used for printing drinks and beer, are generally printed in large quantities, so you can consider buying a large printing machine for printing. Therefore, in the case of relatively saturated output, if the output can only be completed by two medium-sized printing presses, if only one large-sized printing press can be used, it is better to consider buying a large-sized printing press. Factories that mainly print cartons have large product specifications, so there is more room for development and utilization in purchasing large printing machines, which is conducive to improving production efficiency. Choosing a good supplier is an important link in purchasing control of printing equipment. Printing equipment with good performance is very important to improve the production efficiency and product quality of cartons. The purchase control of printing equipment should be carried out under relatively suitable price conditions on the basis of ensuring machine performance and printing adaptability, so as to better consider the printing quality and production cost of products. Therefore, when choosing printing equipment suppliers, it is very important to consider choosing manufacturers with relatively large production capacity and scale, strong manufacturing technology, good product quality and thoughtful after-sales service. They will ensure the future production and quality stability of the factory. Imported printing machines have their advantages in performance and advancement, but they are expensive. In addition, if the equipment is damaged, the supply and price of parts are also a big problem. Some imported printing machines in some factories have to be replaced with other parts or parts processed by themselves because of the supply or price of parts after some parts are damaged, which has certain disadvantages. Therefore, products that can be printed by domestic printing machines are best printed by domestic printing machines. In fact, the printing presses produced by some domestic printing presses manufacturers are also trustworthy in technical performance, production adaptability and after-sales service, and the price of domestic printing presses is much lower than that of similar imported machines, and the supply of accessories is also very convenient. To sum up, the printing machine is the main equipment for carton printing production, which is related to the production cost of carton products and the processing quality of printed matter. Choosing a good printing machine is of great significance for reducing production costs, improving product quality and production efficiency and improving the competitiveness of the factory. Therefore, when purchasing printing equipment, we must do a good job in market research and investigation with a pragmatic and cautious attitude, and finally determine the purchasing direction of printing equipment through serious equipment market analysis and machine application analysis. Only in this way can we avoid detours in equipment procurement, really make the best use of everything, make the purchased printing machine give full play to its due role, and truly become the focus of the factory to create economic benefits.
