Cerrudi compound transfer 9-color printing connection gravure printing machine - Shenzhen Russell's compound transfer 9-color printing connection gravure printing unit purchased by Shenzhen Jingjia is the first in the world to integrate compound, transfer, general printing and UV printing. The integrated gravure printing unit is also the first gravure printing unit in China to use an independent drive. The whole unit consists of unwinding device, transfer, compounding device, six groups of ordinary printing presses, two sets of UV printing presses, large cross-sections, etc., which can be used to compound or transfer gold and silver paperboards and print immediately. Because each unit is driven independently, it can avoid the seam of laser reel paper and break through the restricted area where the gravure printing machine can not print laser reel paper. Due to the relatively large profits from cigarette pack printing in the earlier years, a large number of printing companies were involved in the cigarette pack printing industry, especially in the printing companies in Guangdong and Shenzhen. As a result, cigarette pack printing competition became increasingly fierce. The result also led to cigarette pack design and printing. The process is becoming more and more complicated. Gravure, offset, flexo, screen printing, UV printing and other technologies have come into play. Cigarettes printed with a combination of two or three printing technologies are everywhere. Baisha Group, Hongta Group, Changde Cigarette Factory, General Group Many products also use a combination of printing processes.

According to incomplete statistics, there are more than 200 printing companies based on cigarette packets in China, and most printing companies have gravure printing lines. In Yunnan alone, there are more than 50 gravure printing lines with 6 to 8 colors.
First, no shaft (electronic shaft) transmission technology
From conception to application, the shaftless transmission technology has experienced many years of development in China. So far, not only have we seen in the field of offset printing non-shaft drive technology put into practical production, such as Manroland, KBA, Goss, and Beiren, and other manufacturers have introduced the corresponding equipment, in the gravure field, although lagging behind Well-known foreign manufacturers, domestic manufacturers have also successfully applied shaftless transmission technology to the equipment, which has effectively accelerated the development of gravure printing in China and improved the quality of gravure printing products. Shaftless drive has become a new technical platform for web gravure printing. It is one of the three key technologies for gravure printing machines (non-shaft drive, printing car, sleeve impression cylinder). The shaftless transmission will continue to be the most important technological development direction of domestic gravure printing machines in the coming years, and gravure printing machines for all kinds of applications will use shaftless transmissions.
The extensive reference of the shaftless transmission technology has revolutionized the transmission and manipulation system of web continuous printing equipment. Currently shaftless transmission and registration systems are mainly from Japan and Europe, but they can only be used on a few domestic gravure printers. The development of domestically-produced systems will be the key to the comprehensive upgrading of domestic gravure printers. At present, the SDP series of shaftless transmission gravure presses with speeds of 300m/min and 350m/min in Zhongshan Sunde and the 300m/min high-speed gravure printing machine with electronic shaft drive launched by Shaanxi Beiren have achieved or achieved major technical specifications. The advanced level of international similar products.
As of July 2005, there are 26 sets of electronic axis gravure presses installed in China's mainland, with 16 sets (sets) imported, accounting for 61.5% of the total; There are 10 sets of equipments, accounting for 38.5% of the total. Among the 26 electronic axis gravure printing machines, there are 9 cigarette packet printers, of which 6 are imported and 3 are domestically produced. As of April 2006, Zhongshan Sunde cigarette pack gravure printing machine has produced and confirmed 10 orders for production lines.
Second, the most common solution for gravure printing gravure - gravure gravure printing machine + online cutting machine
The integration of the tobacco industry has led cigarette pack production to a large number of high-speed developments, which provides a huge application platform for rotogravure printing equipment. The rotogravure printing machine has the characteristics of high efficiency and thick ink, and it has significant advantages in printing up to 10 million pieces of cigarettes. At present, a type of gravure printing equipment that is very suitable for cigarette printing companies to choose is a rotary gravure printing machine + online cutting machine (electronic axis) equipment, because the gravure gravure printing machine and the large cutting machine online cut the web printing product online. Cut into single products, it is suitable for mass production, but also can ensure the smooth processing of the smoke label after processing. Domestic and foreign major manufacturers (such as Cyrodi, Bobst, Komori Shangbang, Sunda Sun Yat-sen, etc.) can provide this equipment, in line with the changing needs of this market.
Third, fixed-length tensile transfer production line
In October 2004, Zhongshan Sunde Company launched the first “fixed-length stretch wet method laminating machine†with a number of patented technologies in China; in 2005, with the first domestic “holographic film fixed-length stretching compound transfer machine†"and" SS800 high-speed precision cross cutting machine"
Successively developed in the company of Songde, Songde successfully developed its iconic product—the first folding carton in China with the “fixed-length stretched hologram film + compound + transfer + multi-color gravure printing + connection cross-cuttingâ€. Gravure printing line. Holographic film fixed-length stretching, line wet compounding, connection or disconnection, can significantly reduce the scrap rate significantly reduce costs. The production line has a modular structure, patented technology, high cost performance and other characteristics.
Modularization - four modules: "zero speed" docking; fixed length wet compounding + transfer + (special unit); multi-color printing (with secondary register function); post-press connection unit (transverse, Winding up, etc.);
Patent technology - two key patents: compound transfer printing press (domestic exclusive authorized production and sales), fixed-length stretch wet laminating machine (Songde company);
High cost-performance - performance indicators are at or close to foreign equipment levels; prices are only 1/3 to 1/4 of imported equipment.
Fourth, the combination of printing process is highly respected
In such a situation, the original high-speed rotary gravure printer is no longer adapted to the requirements of a variety of combinations of printed cigarette packs, and its flexibility is greatly limited. At this time, inexpensive domestically produced single-color gravure printers have risen to take advantage of the situation, and in a large variety of combinations of technology to print cigarette packs, they have taken advantage of time and place. Its main manufacturers, Beijing Zhenhengli Printing Machinery Co., Ltd., Shanghai Ziming Machinery Co., Ltd., and Shanghai Hairun Printing Machinery Co., Ltd., have seen booming sales of single-claw machines in the past two years. According to statistics from suppliers of sheet-fed gravure printers, the current installed capacity of domestic sheet-fed gravure printing presses has reached about 200 units, and most manufacturers have a sheet-fed offset press. Their purpose in choosing a sheet-fed gravure press is to cooperate with existing offset presses to achieve a glue-and-concave combination for high-quality, low-cost printing. At present, more than 90% of the plastic and concave bonding processes are used for high-grade cigarette pack printing.
With the structural adjustment of tobacco companies and the further increase in the concentration of cigarette brands, under the condition that the total production volume is relatively stable, the brand's single-batch printing capacity will be greatly improved. In this case, the gravure printing is known for printing large-scale orders. Printing has its place. In the printing process, the ink on the gravure printing is high, the saturation of the ink is good, the level is clear, and the color is bright. At the same time, it can meet the requirements of high-volume product printing and high-speed operation mode, so that gravure printing can complete batch product printing in a short time, and the printing quality is stable. The same batch of products can achieve no color difference.
