Analysis: Tobacco packaging and printing technology and development trends

Restructuring of the tobacco companies and cigarette brands concentration of further improved, the total production of the relative stability of the brands of a single batch of printed Jiang Dedaojiaoda raise, under conditions in 这种 order known for the gravure printing Dagui Mo print come into play. In the printing process, gravure printing ink on the high ink saturation is good, structured, colorful.

    At the same time meet high-volume product printing, high-speed operation mode, so that in a short time to complete the bulk gravure printing products and printing quality is stable, the same product can be realized without color.

    According to incomplete statistics, the country mainly to cigarette packaging printing enterprises more than 200, most of the gravure printing companies have a production line. In Yunnan there are only 6 to 8-color gravure printing more than 50 production lines.

    Shaft (electronic shaft) drive technology

    The proposal from concept to application, no shaft drive technology in China has undergone years of development. So far, we have seen not only in the offset-free shaft drive the field of technology into actual production, such as MAN Roland, KBA, and the North were other manufacturers Gauss introduced the corresponding devices, respectively, in the gravure printing field, despite lagging in foreign well-known manufacturers, domestic manufacturers will no shaft drive technology was applied to the device, effectively to speed up China’s Fazhan gravure, gravure improve the quality of products. Shaft drive to become a new technology platform web gravure printing, gravure printing machine is currently one of the three key technologies (no shaft drive, print car, sleeve type impression cylinder).

    Shaftless made in the coming years will continue to gravure machine direction of the most important technological development, a variety of uses gravure printing machine will be used shaftless.

    Shaftless technology widely used for continuous web printing equipment, transmission, control system to produce a revolutionary effect. There are currently no shaft drive and-Alignment mainly from Japan and Europe, but they made only minimal use in the gravure printing machine. Development of domestic systems will be a comprehensive upgrading of domestic gravure press the key.

    The most common solution packets Gravure: Gravure printing machine drum machine line cutting large sheet of

    Tobacco industry consolidation of production to make a large number of packets, high-speed direction, which provides equipment to the rotogravure a great application platform. The exercise is an efficient equipment, the characteristics of thick ink, printed in easily reached thousands of pieces of cigarette packaging printing in a significant advantage. Now very much in line cigarette packaging printing enterprises to choose a class of rotary gravure printing equipment is the online cutting large sheet gravure machine (electronic shaft) device, because rotary gravure press and cutting large sheet machine line will be web printed products on-line cutting products for the leaflets, suitable for mass production at the same time as the latter can guarantee 烟标 processing smoothly. Both foreign and domestic manufacturers to provide this equipment to meet the market demand changes.

    Composite transfer connection gravure color printing unit 9, is a set of complex, transfer, general printing, UV gravure printing in one unit, is also a gravure using a separate drive unit. All units from the open-book device, transfer, complex devices, six groups of ordinary printing press seat, two groups of UV printing Block, a few large sheet of cross-cutting and other components, can be connected to the compound or the transfer of gold and silver cardboard and printed immediately , because the unit as a separate drive, can avoid the laser web of seams, break the wheel can not be laser gravure printing web Zhang restricted.

    Transfer of fixed-length stretch composite production line

    Connection fixed-length film tensile composite holographic multi-color gravure transfer cross-section of the folding carton gravure connection line. Holographic film fixed-length stretch, wet composite connection, the connection or not connect the transfer, can significantly reduce the rejection rate was significantly lower costs. The line has a modular architecture, patented technology, high cost and so on.

    Modular – four modules: the “zero speed” butt: fixed long stretch of wet composite transfer (special unit): multi-color printing (with the second set; 隹 function); printed after the line unit (cross-section, income volume, etc.):

    — Two key patented technology patents: Composite transfer printing machine (domestic exclusive rights to produce and sell), fixed-length stretch of wet laminating machine:

    Cost-effective – performance at or near the level of foreign equipment: just import prices did not prepare the 1 / 3 to 1 / 4.

    The highly-regarded portfolio printing process

    Since the early years of cigarette packaging printing larger profits, leading to a large number of printing enterprises have been involved in cigarette packaging printing industry, especially in Guangdong and Shenzhen in the vicinity of the printing business, thus creating an increasingly competitive cigarette packaging printing, the results also led to the design and printing of cigarette packaging process more complex, gravure, offset, flexo, screen printing, UV printing technology have battle, by the combination of two or three printing cigarette printed everywhere, many products are also combined with the printing process .

    In such circumstances, the original high-speed rotary gravure press is no longer combined in various ways to adapt to the requirements of the printing of cigarette packets, its flexibility will be greatly limits. At this point, inexpensive ride the wave of domestic color gravure printing machine, combination of multiple technologies in a big situation printing packets possess the favorable factors. According to sheet-fed gravure printing machine suppliers, currently in Taiwan sheet-fed gravure printing machines have been installed capacity is about 200, most manufacturers have sheet-fed offset press. They choose to sheet-fed gravure press was designed with the existing offset with, concave rubber combination to achieve in order to achieve high-quality, low cost printing. Combination of rubber technology now more than 90% Au are used for high-grade cigarette packaging printing.

    And more powerful cigarette packaging printing enterprises, will take a larger investment portfolio to buy the printing production lines, of which a considerable part of the application in cigarette packaging printing.

    1, combination printing advantage

    Combination print results will be pushed grade packets to an unprecedented level and will also be several printing features full play, learn from each other, leading the trend. To use offset printing plus web graphics and gradient patterns, use of gravure ink layer thick, the advantages of ink stability, printing a large area on the ground and spot color, gold and silver, imitation pearl color and a variety of metal etching inks. If you need special finishing effects, it could be screen printing process, such as grinding, Ice, Crystal, wrinkles, etc.. Therefore, offset, gravure, screen printing combination of all three, to the strong cigarette unprecedented visual arts. Plus post-processing technology: sweep gold, UV partial glazing, gilding, from the convex and, more so packets icing on the cake, splendid, amazing.

    2, problems

    While printing technology combined surface printing can bring great results, but its variability is also very likely to cause instability in product quality and increase printing costs. Appropriate combination of process changes, and technology is suitable and beneficial, but too much can easily affect the operation of the process and the quality of printed products, such as the combined process of enlarging its part is when the sampling is very beautiful, but once put into mass production, quality it is difficult to remain relatively stable.

    Combination of printing enterprises in the purchase printing equipment to understand where their product positioning, E3 is not only what to do next, but also understand that after 3 to 5 years to do, what kind of combination is suitable for their own printing equipment, and the selection of equipment must be within our capabilities, according to product requirements, customer requirements P, taking into account the quality, functionality and service to choose their own configuration.
