China's packaging printing industry "tomorrow" (on)

Traditional Printing and CTP
At present, there are nearly 21,000 packaging and printing companies in China. In 2002, the total industrial output value was about 75 billion yuan. The vast majority of these enterprises are small and medium-sized enterprises, which are mainly based on traditional printing. Due to these companies' technology, equipment, capital, customer base and other reasons, they temporarily rely heavily on traditional printing. Because the traditional print printing, use the print control strips, there are printing step ruler, you can step from the ruler of the number of grid printing, the percentage of small outlets and resolution to determine the printing situation and the photosensitive properties of the plate, until Control print quality. Relative to these companies, they already have more mature technologies and experience, so traditional printing is still the basis for the advancement of these companies' technologies.
The application of CTP technology is a matter of recent years. In April 1994, Creo's first CTP (green laser) equipment was put into use. At the drupa printing expo in 1995, Creo introduced thermal-type CTP platesetters; at the same time, Kodak and other companies developed heat. Sensitive CTP plate. In just a few years, CTP technology has been widely applied and developed in the United States, Europe, Japan and other countries and regions. After China's reform and opening up, due to its eagerness for new technologies, China has so far purchased more than 60 CTP equipment (excluding Hong Kong, Macao and Taiwan), such as Shanghai Jielong, Qiuyu, Zhonghua, Xi'an Coal Mining Color Printing, etc. Printing companies have introduced CTPs and they are in good use and have achieved good economic benefits. The reason why CTP technology develops so rapidly is mainly because CTP technology has the following advantages:
After saving the use of imagesetters for printing companies to switch to CTP, they no longer use film (including output film and intermediate film). This is a relatively large expenditure, and CTP also simplifies the process and reduces the possibility of errors.
Save time because you don't use glue marks anymore, so you don't have to make it anymore and save time.
Efficient After using CTP plate making, the preparation time is shorter and the working capacity is increased at the same time. Therefore, for those printing companies that have been able to output full-length film, CTP is a relatively easy thing to do, and it can also achieve high returns while reducing labor intensity.
High-quality use of computer-based plate making, printing quality has been greatly improved. Because many of the instability of traditional printing disappeared, there was no need to worry about overprinting or film scratches, dust on the glue surface, etc.
In addition, CTP Thermal Edition provides abnormal tax profits outlets and exposure latitude, which greatly avoids the underexposure or excessive exposure of the printing plate.
Although CTP technology has many unfavorable factors such as investment, plate material, technology, and management for many packaging and printing companies, under the conditions of market economy, the ultimate goal of the company is to make profits, as more and more low-cost CTPs are available. The system will be put on the market. In 2003 or in the coming years, the application of CTP (including digital printing) will have greater development.
A variety of packaging and printing processes are combined to improve the quality of packaging and printing. In recent years, with the development of market economy, especially food, beverages, cigarettes, medicine, health products, cosmetics, household chemicals, small household appliances, hardware, clothing, toys The rapid rise and development of other industries, coupled with the expansion of China’s foreign trade after China’s accession to the WTO, and the increasing improvement of people’s living standards, have raised higher and higher requirements for packaging and printing products, and the level of packaging has also been continuously upgraded. Therefore, in recent years, from packaging and printing materials to printing technology are constantly changing to meet people's physiological needs and psychological needs, such as: the application of UV matte ink, gold, silver cardboard, laser anti-counterfeiting material applications. At the same time, in order to achieve the selection of packaging and printing materials, we also apply a combination of printing technologies, such as: glue, silk screen printing, combination of concave and silk screen, combination of soft, silk, gravure printing, plastic, concave, and flexo printing, plus With bronzing, embossing, die cutting, printing gold, printing silver, pearlescent, fluorescent, field printing, matte printing, water-based coating, UV glazing, anti-counterfeit printing, anti-metal etch printing and other printing technologies to meet today's packaging The need for rapid development in the printing industry. In the integrated use of these packaging and printing technologies, one of the best companies in the country may have to count Zhejiang Mino Printing Co., Ltd. They used the advantages of offset printing, gravure printing, and silk screen printing to make the quality of cigarette packaging. The grade has reached a new level, and it has also achieved very good economic returns. In 2002, the output value increased by a large margin compared with 2001, reaching as much as 350 million.
Improve quality, reduce costs, and increase profits As China's market economy develops, foreign trade expands, and people’s living standards increase day by day, higher and higher requirements are placed on packaging and printing products, which not only require continuous improvement in printing quality, but also in China. Packaging and printing companies are highly competitive, and prices have become the yardstick of competition; for example, the price of medicines has been steadily declining under the control of the state, benefiting the common people. In addition, this year, the state has explicitly banned the use of tying ropes for bottling beer bottles. Although this has brought good news to production color box packaging companies, there are also problems with prices. In this case, the printing quality is good, the price must be reduced, the packaging and printing companies will have to go across the sea - all show their magic. However, no matter how big a supernatural power is, it is nothing more than strengthening management, adopting new technologies and processes, increasing efficiency, and thus reducing costs. One of the best ways for the color box industry is to use preprints.
Preprinting, as the name suggests, is to print the desired pattern in advance before making corrugated cardboard. The method for producing pre-printed color corrugated cartons is to use a large gravure printing machine to print on a web. The printed web is used as a corrugated paperboard line for the corrugated cardboard production line on the carton face, and then the die-cutting machine is used to cut the corrugated cardboard boxes. Box shaped. That is: gravure printing surface paper (web) - production line corrugated cardboard - computer slitting - computer cross-cut - die-cutting.
The traditional method for producing colored corrugated cartons is to use the offset printing method on a single sheet of cardboard paper first, and then use a veneer machine to paste the printed surface paper and corrugated cardboard, and die-cut into various box-shaped boxes. . Therefore, preprinting has the following advantages over traditional color carton production methods: (to be continued)
