How to flexibly and efficiently use the printing technology of cigarette packs

due to the strong visual impact effect of packaging, especially some high-end packaging products pursue various unique artistic effects in order to be unique in the market. Therefore, packaging and printing are facing a more severe test. As the saying goes. sometimes an inch may prove long, everyone has his own advantages ". different printing processes also have their own merits. Therefore, combination printing has become one of the popular trends in the packaging field. For example, nowadays, many high-end cigarette packs are the crystallization of the combination of offset printing, gravure printing, flexo printing and printing. In terms of combination printing, cigarette packs can be said to be a good example. Don't underestimate these small cigarette packs. It integrates a variety of printing processes, multiple processing procedures and various unique effects Fruit in one. It can be said to be the representative work of modern packaging and printing technology. It is worth mentioning that printing is ubiquitous and even indispensable in cigarette bag printing. We visited several successful enterprises in the industry, mainly cigarette bag printing. Let's see how they use printing technology flexibly and efficiently

equipment selection is the foundation

correct investment is the first step towards success. It is also one of the powerful guarantees to ensure that enterprises win in the fierce market competition. In the face of the diverse printing equipment on the market, you must not blindly buy it. It can be very learned. Let's listen to the experience of successful enterprises

according to Mr. heyisong, deputy general manager of Dongguan Hucai Printing Co., Ltd., packaging and printing enterprises generally need to consider the following factors when selecting and purchasing printing equipment, the shorter the stabilization time is

1. product structure and positioning

considering the order situation of their own products, some enterprises may purchase more than 10 semi-automatic printing machines, while some enterprises may purchase oneortwo fully automatic ones. This should be considered according to the size of the printing volume and the variety of products. Some enterprises may have many kinds of printing products, but the quantity is not very large. In this case, semi-automatic printing equipment may have certain advantages. However, the varieties of some enterprises are relatively single. There are only sixorseven products. Full automatic printing equipment can be considered. The speed is relatively fast

different products usually have different requirements for printing equipment. High grade fine products, such as cigarette packs, have higher requirements for quality and equipment. Due to its outstanding characteristics of high speed, high precision, reliable performance, high efficiency, and suitable for mass printing, full-automatic drum printing machine is widely used in domestic high-end packaging printing. Among them, the performance and reliability of imported equipment are higher, such as Japan Sakurai's full-automatic drum printing machine. The quality and performance of domestic printing equipment have also been greatly improved in recent years, such as Shanghai-_- The full-automatic drum printing machine produced by EP machine is also first-class

2. Matching with existing equipment

printing generally needs to be combined with other printing methods. Therefore, when selecting printing equipment, we must consider the matching with existing printing equipment such as offset press, such as format specification, printing speed, etc

3. Selection of drying device

finally, the printing drying treatment should be considered. Some printers are equipped with a long drying area or a simple drying belt. This depends on the actual needs of packaging and printing enterprises. For example, if only UV printing is used, only UV curing device can be equipped; If other types of printing inks such as solvent based printing inks are used for printing, UV curing and infrared drying devices should be considered. Process control is the key

combined printing is the combination of different printing methods, which seems very simple. But it is difficult to achieve, and it has high requirements for equipment, materials, processes and other aspects

1. quality cost. Overall consideration

the printing materials used in packaging and printing are quite extensive, including paper, paperboard, cardboard, plastic film, etc. different printing materials have different requirements for different printing processes and inks. Therefore, when designing products, printing enterprises must aim at the design style and characteristics of the original According to the specific requirements of customers, and combined with the characteristics of various printing processes and the specific situation of the enterprise, choose the best combination of printing processes

in addition, the cost of printing is generally slightly higher than that of other printing processes. Therefore, the cost must also be considered when designing products to avoid the high cost caused by one-sided pursuit of effect

in actual production, due to the different conditions of various enterprises, the guide focuses on the following four aspects in terms of using and giving full play to the printing characteristics, and the characteristics are also different in style. For example, in terms of cigarette bag printing process design, the principle of Tiger color is that printing is generally only applied to high-end cigarette bag products, and only one-time printing process is considered in the design. Meinong, on the other hand, takes printing as its characteristic printing method. Most of the cigarette pack products printed are printed by printing process, and may be printed twice or even many times

2. Production process. The more types of processing technology involved in reasonably arranging

products. The whole production process needs to go through various types of inn machines and processing equipment. At this time, the production and processing process of products should be reasonably arranged to meet the product design requirements. Here, we mainly consider the quality and accuracy of various printing and processing processes. Offset and gravure printing products are of good quality and high precision. Therefore, offset and gravure printing are generally arranged first, and then the printing process is installed. In addition, we should also consider the performance of ink, which is very important for color sequence arrangement. Because the performance of inks used in different printing processes may vary greatly, this should be taken into account in combination printing. For example, the opacity of the printing ink is often much greater than that of the offset printing ink. If it is designed to offset first and then overprint with printing, the printing ink with strong hiding power will cover some offset graphics and texts printed at the bottom

Mr. Nie Xiaoan of Zhejiang Meinong silk Inn Co., Ltd. gave a typical example: when printing the exquisite "Lushan" cigarette bag, Meinong first used offset printing to print fine patterns, followed by concave convex indentation, and then used printing technology to achieve a large area of pearlescent fission effect

3. precautions

(1) overprint problems between various printing processes, especially the overprint processing between printing and other printing processes. In this regard, the principles and strategies adopted by various printing enterprises are basically the same. That is, those that can be overprinted should be overprinted as much as possible, and overprint should be avoided as much as possible; If overprint is unavoidable, try not to design it into a very fine overprint

(2) control points of printing process. The tension and the pressure of the scraper should be appropriate, otherwise the version is easy to deform, resulting in inaccurate image and text overprint and affecting the product quality

(3) pay attention to the deformation of paper after various printing processes and processing procedures. In combination printing, the paper may undergo large deformation after multiple machines and drying treatment, which will not only have an adverse impact on overprint, but also increase the difficulty of post process. 4. The power supply of the controller must be turned off when plugging in and out of the interface on the controller. The production cycle should be shortened as far as possible, and printing should be carried out as soon as possible after offset printing or gravure printing. The longer the storage time is, the greater the deformation is, and the more unfavorable it is to overprint

(4) control of temperature and humidity in the workshop. The temperature and humidity of the workshop have a certain impact on the performance of the printing materials, the control of the printing process, the overprint accuracy and the product quality. The workshop should be closed as far as possible, and a constant temperature and humidity system should be installed to keep the temperature and humidity of the printing workshop constant

share the joy of success

in the adoption and application of printing technology. Although the strategies and styles of various printing enterprises are different, they all experience the advantages brought by printing and experience the joy of success

the printing process can achieve a variety of special effects, such as ice flower, refraction, frosting, pearlescent, etc. the application of various effects makes the products novel and unique, gorgeous and colorful, and greatly improves the product grade. The use of various ingenious printing processes has become a major feature of Meinong, and has won more customers and broader market space for Meinong. For example, when printing cigarette packs of a certain brand, Meinong uses a special water-based anti-counterfeiting ink, which makes Meinong stand out in the fierce competition

in recent years, Tiger color has made remarkable development. As far as cigarette bag printing is concerned, most of the current key customers are cigarette factories with an annual output of 30 million boxes. Printing is indispensable. And last year, the company developed several new cigarette bag products. The business volume increased rapidly. The existing four full-automatic roller printers can no longer meet the demand of such a large business volume. Therefore, the company recently ordered another full-automatic roller printer from Sakurai, Japan

In a word, the application of printing technology not only greatly improves the product quality, but also plays a positive role in promoting the development of the company's business, and is more conducive to the establishment of a first-class corporate image. I believe that in the future, with the improvement of equipment, materials and technology, printing will make greater breakthroughs and development in the field of cigarette packs. Let's wait and see
