Problems that should be paid attention to when the

  • Detail

With the further development of the market economy, the demand for printing products is increasing, and the application field and scope are expanding, mainly including samples, product advertisements, picture books, trademarks, decoration and color printing packaging. Its printing products are required to be exquisite and high-grade, especially due to the rapid improvement of packaging in recent years, which also puts forward higher requirements for color printing packaging, A beautifully printed package can more attract consumers, enhance the tension of its shelves, and improve the sales rate of goods. The quality of packaging can often directly affect the competitiveness of goods in the market. Therefore, there is an inseparable relationship between packaging products and printing and goods, and its importance is beyond doubt. Color printing packaging is not only limited to sales packaging, but has been extended to large packaging for transportation. From the color printing of white paper in the past in general engineering tests to direct printing on fine corrugated paper, the printing technology and difficulty are higher, and it requires high chromatic accuracy, bright color, correctness and clarity. From the current market, we can see beautifully printed packages of household appliances, toys, porcelain, fruit and food

at present, most packaging and printing enterprises use domestic printing equipment for production, and some packaging enterprises introduce some foreign more advanced printing equipment according to the needs of production development, which is also very necessary to improve technical advantages, adjust the structure of printing products, enhance market competitiveness, increase product diversification and high-quality prints, and learn from foreign advanced printing technology to improve enterprise popularity and economic benefits. However, there are also some problems in the introduction of foreign more advanced printing equipment, such as the production capacity can not reach the original production design capacity, the imported production equipment needs to use special specifications of paper, and some imported equipment itself has some defects, so that it can not be completed on time in the installation and commissioning, resulting in enterprise losses, etc. Therefore, a comprehensive understanding and comparison of the imported printing equipment, especially the quality, technical standards Physical performance and all required indexes that can be achieved cannot be ignored. It can also be pointed out here that due to the continuous deepening of system reform, the bidding of imported equipment from abroad has gradually shifted from the previous government instructions, and now the company has 65 employees who plan to be abolished, to the independent decision-making and market allocation of enterprises, especially with the emergence of a large number of township enterprises and private enterprises, the original rules and regulations can no longer meet the requirements and need to be further improved to meet the new development needs, Therefore, the state has also made corresponding adjustments in the introduction of printing equipment, so that the imported printing equipment is more reasonable and more in line with the current rapid development needs of the printing industry

there is still a certain gap between China's printing equipment and that produced in advanced countries. Although China's printing equipment manufacturing has made great progress in recent years, there is still a certain distance compared with foreign printing equipment. Because of this, we have seen the progressiveness and high output of advanced printing equipment, especially high-speed multi-color printing machines in terms of quality and automation, In the past few years, the relevant departments of the state have introduced foreign high-speed multi-color printing machines, such as sheet fed multi-color offset printing machines with a printing speed of more than 12000 sheets/hour and roll barrel paper offset printing machines with a printing speed of more than 60000 sheets/hour, and other self-use equipment, which can enjoy tax-free preferences. With the introduction of this policy, there is no doubt that packaging and printing enterprises are introducing foreign advanced printing equipment and drawing lessons from foreign advanced printing technology, It has played a great role in promoting the development of China's packaging and printing industry. At the same time, the state gives certain preferential treatment to the imported printing equipment, which is also to make the domestic equipment complement the imported equipment, so that the domestic printing equipment can catch up with the level of advanced countries in a certain period of time, and meet the needs of the majority of packaging and printing enterprises. After all, the price of foreign printing equipment is much higher than that of domestic equipment, which is indeed difficult for the majority of domestic packaging and printing enterprises, However, for some powerful packaging enterprises, they still choose more foreign printing equipment. The main reason is that the quality and performance of foreign printing equipment are relatively stable, and at the same time, the printing equipment is constantly updated, so it has greater technical advantages. After nearly ten years of development in the domestic market, it has a strong influence in the brand effect and accounts for a considerable part of the printing market. Especially in recent years, it has been improved in the after-sales service and spare parts of the equipment, And set up maintenance points and stations to make them more attractive to domestic packaging and printing enterprises

when introducing packaging and printing equipment, taking offset press as an example, enterprises must pay attention to the following aspects: problems:

1 When introducing foreign offset printing equipment, packaging enterprises should determine which type of offset printing equipment to purchase according to the production needs of enterprises in packaging and printing. Because there are many countries where offset printing equipment is produced, and there are many different places of origin, models, varieties and brands, there are many models of the same type of offset printing equipment, so it brings certain difficulties to enterprises in the selection of offset printing equipment. As a packaging and printing enterprise, first of all, through various channels The information and media clarify the preliminary idea of what type of offset printing machine should be introduced. Offset printing machines have monochrome, two-color and multi-color, small printing sheets, folio and other printing equipment with different technical parameters, but they must meet the policies and conditions of imported printing equipment, although there are different opinions on the issue of tax reduction and exemption at present, However, imported offset printing equipment must have high-tech "full-automatic high-speed multi-color printing" (sheet fed multi-color offset printing machine with printing speed of more than 12000 sheets/hour) and "digital printing technology" which are the development direction of advanced countries and printing technology at present. Especially after China's entry into WTO, printing technology must also be in line with the world, so as to maintain the competitiveness of China's printing industry in the world and make enterprises invincible

2. At present, when introducing foreign advanced offset printing equipment, packaging and printing enterprises must purchase through bidding. Therefore, it is very important for bidding to comprehensively understand the quality, price and use effect of offset printing equipment when selecting packaging and printing equipment, and make a detailed comparison of printing equipment in bidding countries, including various performance indicators and production efficiency of printing equipment

taking the introduction of a high-speed folio four-color offset press as an example, in addition to the power supply requirements, it mainly focuses on the following parts: equipment technical specifications and configuration, Feida part, dampening part, ink supply part, printing part, paper receiving device, and others (including automatic air supply system, stepless technology drive system, automatic lubrication system, etc.). In terms of price, due to the recent recession in Japan's domestic economy, which has led to the depreciation of the yen, the price of Japanese offset printing machines has fallen. Therefore, when purchasing similar foreign products, the price factor in this regard is worth considering. However, as a packaging and printing enterprise, we should consider that the printing of fine corrugated board has different requirements from general paper printing, and its printing thickness should be increased. In the past, fine corrugated packaging printing was generally printed on white board first and then pasted on fine corrugated paper, which was time-consuming and laborious, and it was often easy to scratch and damage the printing surface when pasted, which affected the appearance. At present, some foreign offset printing machines can directly print on fine corrugated paper, which can not be said to be a great improvement on packaging and printing and a great promotion on improving the production of corrugated boxes. Generally, the printing thickness of offset press ranges from 0.03 to 1.0mm. It is mainly considered to use more than 450 grams of thick white board for printing, but the thickness of fine corrugated board printing should be increased accordingly. Therefore, increasing the printing thickness to 1.2mm can solve the problem of insufficient thickness. Therefore, the introduction of offset printing equipment should not be blind, but should be considered comprehensively and carefully in many aspects, especially in the bid opening meeting, you can consult and understand the experts participating in the meeting, and listen to their suggestions, which is helpful for packaging and printing enterprises in introducing foreign offset printing equipment. In addition, if the same kind of offset printing equipment has been introduced in China, it is beneficial for enterprises to conduct on-the-spot investigation as far as possible

3. At present, most of the imported foreign advanced four die offset printing machines adopt central integrated middle path control, the processor is centralized in the central box, the unit data exchange path is short, there is no need for optical fiber connection, and the system stability is strong. It mainly depends on more than 20 circuit modules to control the normal operation of the entire offset printing machine, but it is often easy to damage the circuit blocks in it and affect the production in case of improper use. In addition, too long use time is also easy to cause the anti-G ability of components to decline, affecting the normal operation. This situation has occurred in other imported printing equipment, and the components in this aspect are sometimes difficult to buy, so they must be indispensable

generally, the folio four-color offset press of famous foreign brands has a good reputation in quality and use. However, in the bidding document, it is very important to clearly provide all vulnerable parts and spare parts allowed for two years in accordance with the requirements of the bidding document for equipment import, because some Equipment Importers are often vague in the bidding document, and some of them should be provided at random according to water, but some of them have turned into users' purchase, unintentionally increasing the expenses that the enterprise should not spend, resulting in an overall increase in the cost of imported equipment, Therefore, it is necessary to carefully review whether the imported printing equipment, accessories, spare parts list and list provided are consistent with the requirements in the bidding document

4. After sales service is a very important part. Generally, after the packaging and printing enterprises introduce foreign printing equipment, the equipment importers can install and debug the equipment according to the contract. Once the equipment importer wins the bid and the equipment purchasing enterprise signs the contract, the importer should perform the terms of the contract and provide services. In recent years, the work in this regard is still possible, but there are also some problems. For example, after the installation and commissioning of some printing equipment are completed, the offset press also enters the operation stage, which seems to be put into the normal production sequence, but it is often easy to have problems at this time, mainly because the enterprise staff are not familiar with the new equipment and the operation procedures are not proficient after the equipment installation and commissioning

in addition, there are some small problems in the equipment itself, which lead to some equipment failures. Therefore, it is difficult to find the equipment importer to ask for help to solve the problem. Sometimes it is difficult to find it. Sometimes money can only "skim the water", and even ask for fees. Therefore, some enterprises that introduce printing equipment often sigh when they encounter such problems: at this time, the initiative is in their hands, If they want to come or not, you have nothing to do. In short, after-sales service is an issue that equipment importers should pay attention to, and it is also a manifestation of integrity. There should be no situation that "all good words are said before sales, and there is no news after sales". Good quality service is a very important means to open the domestic printing equipment market. It is not easy for a packaging and printing enterprise to introduce an imported printing equipment, so it is strictly controlled to solve all possible problems before the introduction, so as to avoid losses to the profitable industry enterprises and countries.
