The hottest new development of offset ink market i

New development of China's offset printing ink market

with the steady development of China's offset printing market, offset printing ink has also developed rapidly, and its quality level is basically close to or has reached the international advanced level. According to incomplete statistics, in the past two years, the proportion of offset printing ink in China's ink market has increased to 50% - 60%, which is still dominant, and this proportion will not change much for a long time in the future

new requirements of offset printing market for inks

at present, Hualian printing, publishing and packaging printing products are gradually developing towards personalization, diversification and high-end. In order to meet the new changes in the printing market, printing plants continue to update and improve printing equipment. The emergence of high-speed, multi-color, low pollution and high-efficiency printing equipment and the recruitment of printing talents also put forward new requirements for ink manufacturers

1. Printing equipment update

at the just concluded drupa2008 exhibition, Akiyama Corporation of Japan launched megajp5p540dc+rf shuangfeida + double-sided glazing large folio 5+5-color single sheet double-sided multicolor offset press, with a maximum speed of 14000 sheets/hour; Mitsubishi company launched diamondv3000r-8iii single-sided eight color and double-sided 4+4-color printing machine (with turnover mechanism) for printing and packaging research in China, with a maximum speed of 16200 sheets/hour; Libida 106 launched by gaobao company has a maximum speed of 18000 PCS/h, and the startup preparation time is very short. Komori also launched a high-speed printing machine that can flexibly deal with small batch printing, greatly shorten the delivery time, achieve high value-added printing, and adopt the method of one-time paper passing

the characteristics of the above printing machines can be summarized as follows: high speed, high intelligence, automatic machine shutdown, high quality, shortened printing cycle, and improved printing production efficiency. Gravure printing

high efficiency should be transferred from simply improving the printing speed to improving production efficiency, reducing labor intensity, shortening printing preparation time, reducing unnecessary downtime, and realizing offset printing automation (including automatic plate loading, automatic ink feeding, water supply, ink volume preset, automatic adjustment of printing materials, automatic cleaning and other functions). According to the statistics of a Heidelberg lecturer, in China, a Heidelberg printing machine does not stop working 24 hours a day, 365 days a year, and its annual printing volume is only equivalent to the printing volume of a foreign Heidelberg printing machine for 8 months, that is, a foreign printing machine can complete the domestic printing volume of a year in 2/3 of the time. The reason is that the production efficiency and automation of domestic printing machines are low, and there are many manual operation links. In today's personalized era of printing in Shenzhen, the demand for small batch, high-quality and efficient short version live parts has soared. Compared with the shorter and shorter printing time, the preparation time for loading, unloading and proofreading, etc. gradually increases in the proportion of the order production process of adjusting the collet position under the experimental machine. For example, for an order with a print volume of 2000, if the speed of the printing machine is 10000 pieces/hour, Kunming printing can be completed in only 12 minutes, However, the preparation time for manual loading, unloading and proofreading is far more than 12 minutes. If automatic devices are used, the preparation time can be greatly shortened. Hongbo printing in a short edition movable parts printing plant, the printing volume of each batch of movable parts is generally 500 ~ 5000. Using the Heidelberg printing machine with automatic version loading and correction, 33 four-color movable parts can be printed in 12 hours per shift. In other words, on average, a movable part can be printed in only 21.82 minutes, including preparation time and printing time

a recent questionnaire survey conducted in the United States on the needs of offset printing automation shows that most offset printing enterprises in Shantou have increased their interest in the integrated offset printing automation system. 51% of the respondents believe that the integrated automation system has brought certain benefits at present, and 64% of the respondents believe that the integrated automation system is a very important printing manager for printing plants in the next year, Printing plants will gradually adopt automated production methods. In order to meet the requirements of high-speed printing, short version moving parts and integrated automation, the offset printing ink produced by Shenyang printing

ink manufacturer must have the following properties

(1) high speed adaptability: it can adapt to the printing speed of more than 14000 sheets/hour

(2) quick drying performance: due to the short production cycle, short version live parts need to enter the four-color printing machine in the next process immediately after printing, such as glazing, film coating or die cutting, so the ink is required to be dried quickly, which is conducive to the smooth progress of post-processing

(3) printing envelopes with good water resistance and rapid ink balance

(4) stability in the printing process: the ink transfer rate and dot increase rate do not change with the change of speed, time and temperature

(5) packaging is convenient for printing plants: vacuum cans, plunger cans, barrels, cans, etc. suitable for automatic ink supply system

(6) ink has versatility

2. The emergence of sheet fed eight color double-sided offset press

sheet fed eight color double-sided offset press has fast printing speed and high efficiency, providing users with a solution to improve printing productivity and profitability. According to incomplete statistics, the sheet fed eight color double-sided offset printing machines installed in the mainland of China are mainly concentrated in Guangdong, with a number of more than 8; 4 sets in Bohai Rim region; 2 sets in Northeast China; Hubei 2 sets; 1 set in Shandong; 1 set in Xinjiang. The printing quality of eight color double-sided offset printing machine can reach or even surpass that of four-color offset printing machine pet printing, but the premise is that the appropriate ink must be selected according to the type of paper

3. The emergence of light paper

people who often shop in bookstores will find that medium and high-end books and periodicals have tended to use paper with very light texture and soft and natural color for printing. People call this kind of paper light paper. Light paper is a kind of light offset paper packaging bag printing, which originated from munkdkal in Sweden. When it was first introduced to China, it had the name of munkdel. As it is the first light offset paper printing machine introduced in China, this kind of paper is now habitually called Mengken paper in China. The wide application of light paper is the development trend of the book publishing industry. In developed countries such as Europe, America and Japan, more than 95% of the books in bookstores are printed on light paper at the national printing managers' annual meeting, which requires offset printing ink to adapt to the nature of this paper. If you use light paper to print high-grade books and periodicals, the effect of using anhydrous offset ink is better. CD printer

4 Due to the rapid development of offset printing technology, small and medium-sized multi-color offset printing machines are entering the domestic commercial color printing market on a large scale and printing is fully open, which is the result of commercial printing products moving towards differentiation, functionality and short edition. The technologies used for high-speed large and medium-sized multi-color offset printing machines, such as online glazing, UV printing and flip printing, are configured on small and medium-sized offset printing machines, making them flexible, fast and with technical content, improving the added value of printing products configured by the gold assay high configuration testing machine, printing self-adhesive at the same time, expanding the application field

some far sighted printers have begun to adopt the process of four-color offset printing and line glazing, which indicates the broad prospects of short version color printing business. Some offset printing machine manufacturers have also launched corresponding equipment to meet the new market trends, such as Heidelberg's launch of speedpa M52 online glazing and UV offset printing machine small printing machines, which require the ink to have the performance of slow drying on the printing machine and rapid drying on the substrate material. In order to meet the requirements of users for ink products of different quality and price grades, Tianjin Toyo Ink Co., Ltd. has launched TNS, caixiaon, tgson and other offset printing bright, fast drying and non skinning high, medium and low-grade inks for users to choose

5. Environmental protection requirements

in recent years, with the development of economy, the voice of environmental protection has become higher and higher. The printing industry has put forward new requirements for offset printing ink in terms of non-toxic and pollution-free. Environmental friendly offset printing ink has been widely concerned by users and has been applied to packaging, newspapers, commercial printing, etc. Environmental friendly offset printing inks have been widely used in the United States, Japan and other countries, but the application of Hualian printing in China is still quite small. There are technical factors, but the main reason is insufficient understanding. The national printing managers' annual meeting

environmentally friendly offset printing inks are mainly aromatic free soybean inks. PAH (polycyclic aromatic hydrocarbon) contained in traditional ink is a volatile solvent printing film, which is harmful to human body; The volatile organic compounds contained therein not only increase air pollution, but also cause harm to human body. Offset printing soybean ink uses soybean environmental friendly materials to replace some petroleum solvents, which can reduce environmental pollution and human injury. The aromatic free soybean oil (afsoy) sheet fed offset printing ink, rotary ink and thermosetting rotary ink produced by Tianjin Toyo Ink Co., Ltd. not only have good printing suitability for Jiaxing printing, but also meet the environmental protection requirements, and can provide corresponding environmental protection certificates

current situation of domestic offset printing ink market

in recent years, with the development of China's printing industry, the pace of development of the domestic ink industry is also accelerating. With the installation and operation of a large number of imported and domestic high-speed offset presses, the adoption of new printing materials, and the special requirements of new printing processes and post press processing, ink manufacturers rely on scientific and technological progress Hongbo printing, constantly develop marketable new products, improve old products, enrich product varieties, publish periodicals, and gradually approach the international advanced level in product quality. The renewal of ink production equipment and the improvement of production technology have gradually attracted the attention of ink manufacturers

in the past 10 years, major domestic ink manufacturers in Tianjin, Shanghai, Hangzhou, Shenzhen, Taiyuan and other places have paid attention to collecting market information and printing materials, and continuously developed new offset printing ink products that meet market needs, such as bright and fast drying ink, cardboard ink, matte paper ink (matte paper ink), rotary ink, cold set offset printing rotary ink, UV ink, offset synthetic paper ink The output of iron printing ink and thermosetting offset rotary ink newly launched in China in recent years has increased year by year, and the quality of stereo printing is close to the international advanced level, which has been recognized by printing customers at home and abroad. In addition to replacing the high-end offset printing inks that used to be imported in the domestic market, some domestic offset printing inks have also entered the international market. Some high value-added special offset printing inks have also been successfully developed, meeting the requirements of special printing. Hongbo printing

sheet fed offset printing ink has maintained a steady upward trend in the domestic printing market. Printing UV, with the innovation and improvement of printing machines, domestic sheet fed offset printing ink meets the needs of high-speed, multi-color, fast drying, high efficiency and energy saving. There is an urgent need for China's relevant export enterprises to pay attention to issuing new products for daily printing, expanding its application in the field of packaging and printing, such as tobacco, wine, food Cosmetics and other industries meet the performance requirements of book printing, high gloss, high concentration, packaging and printing, fast drying and friction resistance; Rotary offset printing ink also adapts to the rapidly growing demand of newspaper industry and commercial printing. Printing Co., Ltd. continuously improves the quality level and output. At present, China's offset printing ink manufacturing enterprises mainly include: Tianjin Dongyang Ink Co., Ltd., Taiyuan Gaoshi Laurie Ink Co., Ltd., HANGHUA ink Chemical Co., Ltd., Shanghai Peony Ink Co., Ltd., Shenzhen shenri Ink Co., Ltd., Shanghai DIC Ink Co., Ltd., and Shanghai ink
