Trend of Chinese flexographic printing technology vector paper cup
2017/11/15
Times are developing and society is progressing. With the development of social information and economic globalization, printing is also undergoing tremendous changes. In
the "flat, convex, concave, soft," the four major printing processes,
derived from the flexographic printing flexo, after decades of twists
and turns, finally dawn, flexo market from small to large, from weak to
strong The trend has caused widespread concern in the market. --- Vector paper cups
According
to Japan's "Printing Information" magazine statistics: the 20th
century, the late 90s, global flexo printing every year at an alarming
rate of 70% growth, flexo printing in 2000 accounted for 18 to 19% of
the global printing market. Experts predict that by 2005, Flexo is expected to rank second in the "Big Four" print layout. However, at the same time, the growth of global gravure was flat, while offset printing showed a slight decline. So why flexo from the "flexographic printing" ugly duckling transformed into a beautiful "white swan"? The
main reason for the analysis is that in recent years, flexo has been
greatly improved due to the application of a large number of new
technologies such as ceramic anilox rollers, sleeve rollers, water-based
ink, UV ink, laser engraving technology and computer technology Its printing quality, coupled with the environmental advantages of
water-based inks in Europe and the United States market has been a huge
development.
Development Status of Flexographic Printing Technology in China
China in the mid-1990s there have been introduced flexo equipment heat, forming a strong "flexo wind." By
the end of 2003, more than 270 flexo printing equipment had been
introduced nationwide, of which 90% were narrow-format unit flexo
machines and stacked flexo machines, and about 10% of wide-band
satellite flexo machines. It
is estimated that the introduction of domestic flexo machines is
increasing by about 30 units per year. At present, there are about 350
flexo printing production lines in China, of which about 80 are narrow
flexo printing production lines independently developed and produced in
China about.
In
2001, Shandong Quanlin Paper Co., Ltd. introduced a world-leading
technology of shaftless transmission, width 1300mm, 8-color high-speed
satellite flexographic printing production line and cross-cutting
machine and related equipment from German F & K Company. The machine speed is basically stable at 200m / min, more than double the speed of the domestic unit flexo machine. Printed solid color field consistent, network clear, high precision overprinting, quality upper. Now mainly used in milk, fruit juice carton packaging and high-grade packaging printing.
2002
Shanghai International Paper Co., Ltd. from Germany BHS printing
machinery company introduced two 8-color, 820mm width satellite flexo
production line, speed 250mm / min. Now three classes of production, for the larger dairy enterprises such
as "Mengniu", "Yili", "Bright" roofs and other beverages, fruit juice
to provide packaging products.
In
addition, in 2003 Guangxi Guilin Aoqun Co., Ltd., Shenzhen Jinjia Color
Printing Co., Ltd. and Lanzhou New Century Color Packaging and Printing
Co., Ltd. and other units in order to meet the environmental
protection, new security, new printing materials and other tobacco,
medicine, cosmetics packaging, ticket printing Need to have introduced a number of Czechoslovakia EM410 8-color, 9-color, and 10-color flexo machines.
Due
to the rapid development of flexographic printing technology in our
country, the development and production of domestically produced
flexographic printing machines, anilox rollers, plate materials,
printing inks and plate making technologies are strongly promoted. There
have been more than 10 manufacturers (such as Xi'an Black Cattle,
Shaanxi printing, Beiren Fuji, Shanghai Purple, Qingzhou Italian high of
God, Wenzhou, etc.) successfully developed a wide range of
specifications, narrow-format unit flexo machine. Zhejiang Ryan Machinery Factory also produced a laminated four-color trademark flexo machine. Domestic
flexo printing quality can completely meet the requirements of
packaging and printing, on the whole, the equivalent of imported
products in the upper level. The
domestic 8-color unit flexo machine general price is about more than
100 million yuan, while the same specifications of the imported
equipment is required more than 500,000 US dollars, actually several
times higher than the domestic equipment. Therefore, due to the improvement of processing and manufacturing of
domestic flexo machines, coupled with the price advantage, Beiren Fuji
and Qingzhou Yigao Fat Packaging Machinery Co., Ltd. have also exported
to Japan and Vietnam.
The
key component of flexo printing machine is anilox roller, Shanghai
Institute of Printing Technology took the lead in the successful
development of electronic engraving metal anilox roller. Then ceramic anilox roller, laser engraved rubber seamless roller, rubber seamless sleeve, also have come out. In
the flexo plate making, due to the Dalian Foley Flexo Plate Co., Ltd.,
Shanghai Renshi plate today good company introduced a number of units
such as the United States, the Netherlands and other foreign set of
flexo plate making equipment, technology and technology software, so
that domestic Flexible platemaking technology soon with the international level at the same level. In
addition, the flexo ink used to start also need to import from abroad,
and later Shanghai Institute of Printing Technology, Shaanxi New Century
Institute of Printing Materials and other units co-operation, the
successful development of the water-based ink, water-based Varnish,
water-based additives and UV Inks, UV varnishes, UV auxiliaries, etc., make flexo a solid foundation for "green printing".
After
nearly 10 years of production practice, flexo printing in China's
packaging and printing market has initially formed a scale. Printing range, types continue to expand, flexo market share also gradually increased. However, compared with foreign advanced countries, we still have a long way to go. For
example, North America, Europe and other packaging and printing markets
more mature countries and regions, flexo market share has accounted for
70% of the packaging and printing market, while our situation is
unsatisfactory, much lower than 10%, and most of them are medium and
low-grade printing product.
At
present, China's flexo printing has been fully able to meet the
requirements of cigarette packs, pharmaceutical packaging, food
packaging, trademark labels, stickers printing and other packaging and
printing, and can be completed online printing glue, die-cutting and
other processing can be enhanced Work efficiency, reduce costs, improve production efficiency. According to statistics, now the domestic flexo printing machine for
cigarette packaging accounted for 30%; used for label printing accounted
for 15%; used for adhesive printing accounted for 35%; other printing
accounted for only 22%.
In addition, domestic production of cutlery, paper cups, beverage packaging, 80% are using flexographic printing. Food industry packaging paper and packaging printing, but also the gradual adoption of flexographic printing. For example, hamburger wrapping paper, McDonald's food packaging, Erie ice cream boxes and so on have adopted the flexo method. Long
its is the current flexo application of the best, and the largest
proportion of the corrugated box printing, annual sales of about 70% of
flexible plate are in the carton industry. In
addition, some international multinational companies in Shanghai and
Beijing consider that "flexo printing is green printing" because they
consider the use of water-based inks as flexo printing. Pollution of
printed products is not harmful to health and environmental protection.
The "green packaging" Will certainly greatly win the customer's approval, therefore, these brand-name products are used flexo packaging. Seen in this light, flexo printing in packaging and printing industry
has shown its superiority, not only its wide range of carrier printing,
and print quality has gradually and offset printing, gravure move
closer, with broad application prospects.
Trend of Flexographic Printing Technology in China - Vector Paper Cup
China's
packaging and printing industry has been the original offset printing,
lead printing two hegemony situation, is gradually transition to offset
printing, gravure, flexo three pillars of the pattern. And in the next few years, the market share of the three will be further balanced. Now its development trend is briefly summarized as follows:
1,
Judging from the status quo and history of flexo printing in our
country, great progress and development have indeed been made in the
past ten years. On
the one hand, the domestic flexo printing machine and its supporting
equipment research and development work has been firmly rooted in the
field of China's printing and manufacturing industry, is currently to
the middle and high-end products to enter; the other hand, flexo
printing in China's packaging and printing market The
initial formation of the positioning phase, printing range, types
continue to expand, flexo market share increased rapidly, flexo product
quality improved significantly. Trademark
labels, plastic flexible packaging, folding carton is the current flexo
production in the packaging and printing market in the three
"highlight." To be sure, printing high-precision products is definitely a trend of flexo printing in the future.
2,
China's current introduction and self-developed flexo machine organic
group, stacked and satellite three, crew and satellite are the two most
important models. Compared with the unit type, satellite flexo machine has a higher overprint accuracy. Because
the tape is tightly wrapped in the center of the impression cylinder,
so the tension is very stable; In addition the machine structure is
simple, good rigidity, short distance between the embossing points, but
also easy to register control, the use of more stable performance. In
the European and American markets, satellite flexo machines account for
about 70% of the total flexo printing machine market, most of which are
used in flexo printing, trademark labels and corrugated pre-printing. Satellite
flexo machine technology in foreign countries is quite mature, but only
in its infancy in China, but revealed a strong vitality. It
can be expected that satellite flexographic printing presses will
surely occupy a very important market in the field of packaging and
printing as the domestic market pays more and more attention to the
development of flexo printing technology as well as the perfect
technology of flexo printing equipment, inks, plates and plates. Share. In the next few years, the satellite flexo printing machine will be
our country flexo machine development and production of "top priority."
3,
flexo plate making is also a very important issue, not only its plate
making fees much higher than the offset, but also a headache is its
printing durability is low. Especially
as the medium and high-end products, the network cable version is even
more prominent outlets easily expanded, paste the phenomenon of piling
ink often occur, relative to 175 lines / inch or higher number of lines
will not be able to achieve normal mass production. And reach the number of network lines close, medium and high-end products, fine, delicate degree is difficult to reflect. At
present, there have been several domestic use of laser engraving
flexible version of the new production process, this process on the
number of high-speed network and durability have significantly improved. Therefore, many professionals predict: take too long, there will be a
new breakthrough in flexo printing high-precision products, the use of
laser engraving plate will be an inevitable trend.
4,
shaftless drive technology is the world's most advanced printing press
drive system, it is the use of electronic gear instead of the
traditional mechanical gear, remove the drive shaft. That
is, in each printing unit, AC vector variable frequency motor is used
to drive independently, and the controller performs frequency conversion
speed regulation to ensure the synchronous operation of each printing
unit. At
present, more than 50% of the advanced high-speed high-speed gravure
presses in Europe adopt the shaftless transmission system. Only 30% of
the high-end products in Japan representing Asian technology adopt the
shaftless transmission system. The use of high-end shaftless gravure printing machine in China has just started. In 2003, Zhongshan Songde Packaging Machinery Co., Ltd. and Shaanxi
Beiren Printing Machinery Co., Ltd. successively developed the shaftless
high-speed gravure printing machine.
In
addition, Valmet machining machinery entered the field of shaftless
development of flexo two years ago and has developed several 8-color,
non-shaft-driven Rotomec flexo machines. Today
the company extends the development of a shaftless flexo machine to the
10-color field and successfully developed a new RotomecEG500-3 10-color
shaftless flexo machine. Therefore, experts believe that: Shaftless drive technology is not
only a trend of today's gravure printing machine, the same high-end
flexo printing machine is also an inevitable trend of development.
In
short, as China's flexo technology further develops in depth, we should
sit down calmly and think about it: a careful analysis of past major
experiences and lessons, and a clear understanding of the prosperity and
prosperity behind Many
defects and deficiencies (such as blindly introduced, equipment
selection is not complete, resulting in waste; lack of flexo auxiliary
materials, poor supply channels; technical training can not keep up, low
level of worker operation, etc.), the experience of the car can "repeat
the mistakes ". We
have every reason to believe that with the concerted efforts of all our
colleagues in the industry, we will actively explore the key points and
overcome all the unfavorable factors. We will absorb and absorb new
foreign technologies and technologies in a timely manner. Just around the corner, let us soon usher in the development of flexo printing another spring.
