[Carton printing machine]Experience: how to buy carton printing machine

Experience: how to buy carton printing machine with the continuous improvement of the level of printing science and technology, now on the market the varieties of printing machine diversification, equipment structure, some also have some post-processing production functions, it can be said that the printing machine manufacturing technology is now more mature, which improves the quality of printing products and production efficiency, reduce the consumption of printing production, and has played a great role in promoting. Due to the different types of printing equipment, its use is also somewhat different. Printing machine for carton production, must be consistent with the characteristics of carton products and printing production process, in order to achieve better meet the production requirements, improve economic efficiency of the fundamental purpose. Carton printing machine type, structure and production characteristics of the understanding of the carton printing machine type and structure of a variety of carton printing machine, there are suitable for pre-printed carton face paper gravure printing machine, flexographic printing machine and lithographic printing machine, there can be online to complete the varnishing, hot stamping, silk screen, etc. multi-functional models, there is the structure of the web, there are also flatbed paper models; more suitable for the corrugated cardboard directly to the printing, the equipment can be online! There are also flexo printing machines suitable for direct printing on corrugated board, and the equipment can also be connected to the machine to complete slotting, corner cutting, slitting and creasing. Pre-printing equipment for cartons means that before the face paper (such as kraft cardboard or white cardboard) and corrugated board are laminated, the printing machine is used in advance to print the graphics on the box in the position corresponding to the face paper, and then the printed face paper and corrugated board are laminated, and then die-cutting and creasing and molding, which is made into a complete finished carton. This type of machine is characterized by high printing productivity and printing accuracy, more suitable for printing beverages, beer, electronic equipment and other food packaging of high-grade color corrugated boxes. Semi-finished products printed by pre-printing equipment of web structure can be directly laminated into corrugated cardboard on the tile line. Due to the production of a certain amount of heating and molding time, the use of such equipment can better improve the strength of corrugated boxes. The flexographic printing machine suitable for corrugated cardboard printing is printed on the surface layer of uneven corrugated cardboard, and the effect of the quality of the graphic ink color it prints is obviously inferior to the printing quality of the pre-printing equipment, and is especially unsuitable for the printing of fine dot-colored products, so this type of machine is generally only suitable for the printing of medium- and low-grade cardboard products with coarse graphic layouts. Selection of basic principles of carton printing machine selection of carton printing machine from the economic, technical and applicable principles, in order to better improve the economic efficiency of enterprises. The so-called economic, that is, the investment in equipment should be small, the equipment should be utilized in large space, the operator used in the machine should be less, and the production cost should be low, which is the basis for improving the economic efficiency. From a technical point of view, the product layout is relatively fixed, the number of printing is particularly large, the printing area is also large, the layout of the ink layer is relatively thick products, should be selected for printing with gravure printing presses, is conducive to improving the printing quality of the face of the paper and production efficiency. Printing page colorful products, graphic printing area of a larger layout, layout by the dot color products and the size of each batch of printing the number of indeterminate products, lithographic presses can be selected for printing. For the surface of the rougher surface paper material, simple line version, ink color requirements are not strict, the layout of the local text, patterns need to be frequently changed or the need for multiple reprinting of the product, as well as die-cutting and creasing of the layout of the carton products is relatively simple, rough, you can choose to buy flexographic printing and slotting machine, directly on the corrugated cardboard printing and on-line slitting, cutting corners, slotting and creasing. Applicable is the requirement of the type of printing machine purchased to suit the characteristics of the factory's product structure. Such as a variety of structural carton products, production scale of the factory, can have both gravure, lithographic and flexographic printing machine. In this way, the comprehensive utilization of equipment, production efficiency and product printing quality can achieve a greater improvement. In short, carton enterprises to buy printing machine must be clear about the production direction of their factories. That is to say, before the purchase of machines must first be clear about the characteristics of their products, and to accurately understand the performance and characteristics of a variety of printing presses in order to correctly determine what models to buy and configure which ancillary equipment or devices, so that the equipment purchased to give full play to its due role. Selection of printing machines should understand and master a number of elements of the correct purchase of printing machines related to the factory's productivity and product quality can be normal play. Equipment procurement is different from raw materials, after all, once the machine is put into use, generally can not be returned. If there is no accurate understanding of market conditions, blindly purchased printing equipment, after a period of time after the use of the machine, even if it has been found that there are drawbacks and not suitable for the characteristics of the factory's products, it is too late. Therefore, the purchase of printing machines must be cautious attitude, first carefully examine the market situation, to understand and grasp the latest technological developments, to be clear about what kind of products need to use what kind of printing machine, thus contributing to the improvement of productivity and quality, and is conducive to reducing consumption and production costs, which should be considered the most important factor. Therefore, the purchase of printing machines should focus on mastering the following aspects of the situation: understand the performance and use of the machine to understand the performance and use of the printing machine is very important knowledge of procurement, but also to the relationship between the purchase of the printing machine can be suitable for the characteristics of the factory's products and to ensure that the realization of the key aspects of the low-input high-yield. Therefore, before the purchase of equipment must be through careful consultation and in-depth market investigation and understanding, in order to accurately recognize the actual performance of the printing machine and the exact use. Market research is not only simply to the equipment manufacturer to visit the understanding, but also to the relevant carton factory, printing machine factory to understand the actual use of the printing machine performance and situation, so that the understanding can be more accurate, can better avoid the procurement of one-sidedness and blindness. Understand the technical performance of the printing machine various printing machines have technical performance, requirements and scope of application and other requirements. Therefore, the procurement of printing presses to understand the relevant technical requirements, in order to reasonably select and acceptance of the standard requirements, so that the purchase of printing presses to better meet and comply with the performance of equipment and production requirements. Printing machine technical requirements mainly include machine specifications, maximum and minimum printing width, printing material thickness, overprinting accuracy, machine speed, motor power, etc., which must be grasped clearly. Choose the right price for the printing machine printing machine price determines the cost of production, to get out of the "good printing machine price must be high" and "cheap no good" misunderstanding. In fact, due to the level of production management, production scale and production of regional economic differences, the same type of printing machine, there will be a certain price difference, and even some factories produce advanced performance of the printing press, but the price is lower than other factories in general performance of the printing machine. Therefore, the purchase must pay attention to the understanding of many parties, investigation and comparison, so that the purchase of the printing machine production capacity and product printing quality both to get a better guarantee, the machine price is reasonable. According to the actual situation of the factory to determine the purchase of printing machine varieties and the number of reasonable to determine the configuration of the purchase of machines. The so-called machine configuration refers to the structure of the printing machine on some of the production function and its devices, such as the number of printing units, on-line configuration of the varnish, die-cutting, hot stamping and other units or devices. Machine configuration should take into account the characteristics of the production process, for example, on the flexographic printing process characteristics, it is with the lithographic and gravure printing process there are obvious differences, such as lithographic and gravure printing process, the same color layout on both the field and fine text, both lines and reticulation of the product, as long as the production of a plate using a color group can meet the requirements of the quality of the printing, and if the flexographic process Carried out, it is necessary to split a page into two plates with two color groups for printing, in order to better overcome the process prone to paste the plate and other quality problems. Therefore, if you choose flexo printing for this product, you have to consider the reasonable allocation of the number of color groups. Such as the printing of pre-printed carton tissue, cartons and other packaging prints mainly, varnishing, die-cutting, hot stamping and other processes are often indispensable, it is necessary to consider the configuration of drying devices and the corresponding functions of the unit. Reasonable purchase of machine specifications printing machine specifications related to the size of the printing width, the machine's printing area means high productivity. Large and medium-sized carton products to expand the size of the width is generally more than 1000mm. Therefore, on the one hand, the printing width of the purchased machine should also be above 1000mm to meet the production requirements of carton products; on the other hand, the business competition in carton industry is quite strong now, and the micro-profit situation of printing is increasingly coming out, some printers will improve the printing profit target, aiming at improving the printing width, and the number of products is large, and often through the use of spelling large version of the printing, to Reduce production consumption and production costs, improve the effectiveness of printing and production efficiency. Printing beverages and beer, such as the main pre-printed carton products, the general number of prints are relatively large, can be considered to buy a large printing press for printing. Therefore, in the case of saturated production, if two medium-sized printing presses to complete the output, as long as a large-scale printing press can be used, or consider purchasing a large-scale printing machine is good. Printing carton based factories, product specifications are relatively large, buy large-scale printing machine has a greater development and utilization of space, is conducive to improving production efficiency. Choose a good supplier to choose a good supplier is an important part of the procurement control of printing equipment, good performance of the printing equipment on the carton production efficiency and product quality improvement, are essential. Printing equipment purchasing control should be in the machine performance, printing adaptability to ensure that the basis of the price is relatively appropriate conditions, so as to make the product printing quality and production costs are better balanced. Therefore, the choice of printing equipment suppliers, to consider the choice of production capacity and scale is relatively large, strong manufacturing technology, product quality, good after-sales service manufacturers, which is very important. They will play a certain role in guaranteeing the stability of the factory's future production and quality. Imported printing presses in terms of performance and sophistication has its superior side, but there is a relatively expensive problem, in addition, if the equipment is damaged after the supply of spare parts and price, is also a big problem. Some factories imported printing machine in some parts after the damage, because of the supply of parts or price reasons have to use other parts or their own processing parts for alternative use, which has certain disadvantages. So you can use domestic printing machine printing products, it is best to buy domestic printing machine for printing. In fact, some domestic printing machine manufacturers now produce printing machines, in terms of technical performance, production adaptability, after-sales service and other aspects of the trustworthy, and the price of domestic printing machine is much lower than similar imported machines, parts supply is also very convenient. To sum up, the printing machine is the main equipment for carton printing production, it is related to the production cost of carton products and the processing quality of printed materials, choose and buy a good printing machine to reduce production costs, improve product quality and production efficiency, improve the operation of the factory's competitive vitality, has a very important significance. Therefore, the purchase of printing machine, we must be pragmatic, cautious attitude, do a good job of market research and investigation, and through a serious analysis of the equipment market and machine application analysis, and finally determine the direction of the procurement of printing equipment, so as to better avoid a detour in the procurement of equipment, and really make the best use of the goods, so that the purchase of the printing machine to give full play to the role it should play, and really become a factory to create economic benefits. The focus.
