Along with our country market offset the steady development of the offset printing ink, also get the rapid development, and its quality level basic close to or have reached the international advanced level. According to not complete count, nearly two years shenzhen printing ink, offset printing in China for ink market in the proportion of occupied rose from 50% to ~ 60%, still dominant, and the proportion in the future for quite a long time won't have big changes. Offset printing market for ink proposed the new requirements the current hualian printing, publishing and packing print is gradually to a personalized, diversification and high-grade change direction, in order to meet the new changes printing market, enterprise constantly update and improve printing equipment. And high speed, multiple color, low pollution and high efficiency of the printing equipment in recruitment, printing ink manufacturers set the new request.
1. Printing equipment update in just after the end of the drupa2008 exhibitions, Japan felt MEGAJP5P5P540DC + RF sf corporation out of the double glazing + 5 + 5 color brochure off more than double color offset printing machine, highest speed 14000 zhang/hour. Mitsubishi company came out with IAMONDV3000R-8 type III single 8 color and double-sided 4 + 4 color saut (with flip institutions of China printing and printing), the highest speed packing 16200 copies/hour. Global group company launched the will of 106 top speed 18000 zhang/hour, and to boot for a short time. Sam company has introduced a flexible coping small batch printing, greatly shorten the delivery date, to realize high added value, and the use of disposable paper printing a way of high-speed printing press. The characteristics of the printing press summed up and have some: high speed, high intelligence, and high quality, printing cycle shortens, printing production efficiency improving. High efficiency should improve the printing speed transfer to pure improve production efficiency, reduce labor intensity, shorten the printing preparation time, reducing downtime, realize the automation (including automatic offset printing, automatic to ink, water supply, default, automatic adjustment of ink printing materials, such as automatic cleaning function). A lecturer statistics: in domestic Heidelberg, a printing machines Heidelberg 365 days a year 24 hours every day down China's printing industry to the annual report, one year is only printing a printer foreign Heidelberg 8 months, namely the printing foreign a printing press with two-thirds of time to complete a year of domestic printing. Reason is that domestic printing machine production efficiency and automation artificially low, operation links. In today's individualized era printing shenzhen, small batch, the high quality, the high efficiency of the short version in a live, relative to demand more and more short time, loading and unloading of the version and printing school version and preparation time in order in the process of production is gradually increasing proportion of the jianyang printing, such as a printing for 2000 zhang's order, if the speed of the printing press about 10000 votes/hour, just 12 minutes after printing, printing kunming and artificial loading and unloading the version and the school edition of the preparation time but far more than 12 minutes, if you use automatic device, can greatly shorten the time to prepare. In a short version of a printing shop at the live printing, each lot of live a general printing is 500 ~ 5000 zhang, adopt the automatic printing and school version of Heidelberg printer, a flight to 12 hours can printing 33 four-color live a Beijing screen printing, that is, the average a live only 21.82 minutes to a finished printing, including preparation time and printing time. Recently the United States needs to offset automation a questionnaire survey, most of the offset printing shantou enterprise integrated automation system to offset the increased interest, 51% of the people surveyed think the integrated automation system at present has brought some benefits, 64% of the respondents believed that in the next year to enterprise integrated automation system is of great importance, enterprise will be printing managers gradually using automated production mode. The offset printing ink manufacturers to suit high-speed printing ink, the short version live parts, integrated automation of demand, must have the following performance. (1) high adaptability: can adapt 14000 zhang/hours of printing speed.
(2) a fast drying properties: live a short version because production cycle is short, printing needs after going after working procedure four-color printing press, such as glazing, drugs or die cutting, therefore, ask ink can rapidly drying process after, so smoothly.
(3) water resistance, good printing ink fast envelope, balance.
(4) in the printing process of stability: the transfer rate, outlets ink with increasing rate of speed, time, temperature changes.
(5) packed convenience enterprise use: vacuum pot, adapt to the automatic ink system for the piston cans and bottled, canned, etc.
(6) ink has domestic sex.
2. Sheet of paper 8 color offset perfector appear of single paper offset perfector 8 color printing speed, high efficiency, printing provides customers with a improve productivity and profitability of printing solutions. According to not complete count, installation of the sheet of paper in mainland China 8 color offset perfector mainly concentrated in guangdong area, number more than eight Taiwan; Link bohai sea area; (4) 2 sets in northeast China; 2 sets of hubei province; Shandong 1; Xinjiang 1. 8 color offset perfector the print quality can reach even beyond four-color offset printing machine pet printing, but the premise is according to the type of paper must be suitable ink.
3. Light paper often appear around the bookstore will find that, medium and top grade books has tilted use texture is very light, color gentle nature of printing on paper, people say this kind of paper for light paper. Light paper is a light JiaoBanZhi bags from Sweden, printing Munkdkal (have), when it will dell was first introduced to China, and then had the "with the name" Ken. Because it is our country the first light of the introduction of JiaoBanZhi printing machines, so now domestic habitually says this kind of paper for "be Ken paper". The wide application of light paper is the development trend of the book publishing industry in Europe and us, Japan and other developed countries, and more than 95% of the books in the bookstore is with light paper printing national printing managers, which requires the annual meeting of the offset printing ink must adapt to the nature of this kind of paper. If use the light of paper printing, the high-grade books without water offset printing ink the effect is much better.
4. Small and medium sized many colors offset printing presses are on the rise because of the rapid development of technology offset printing machine, small and medium sized many colors offset printing presses are mass into the domestic commercial printing market fully open printing, this is business to differentiation, function and print the short edition towards the results. For the large and medium sized multiple color offset press technology such as online glazing, UV printing and printing for medium and small size flip configuration on the offset wide, flexible, rapid and with the technical content, improving the value of prints and printing adhesive, expand the application fields. Some have vision of printers are beginning to use four-color offset printing technology, the polish and attachment indicates the short version color printing business and broad prospects. Some offset printing machine manufacturers have also launched the corresponding equipment to meet the market trend, such as Heidelberg launched the speed M52 online glazing and UV offset printing machines, this kind of small printing ink machines requirements in printing machines with slow dry, in their material on the performance of the rapid drying. In order to satisfy the users to different grade of quality and price of product requirements, tianjin ink Oriental inks Co., LTD launched TNS, CAIXIAON, such as light TGSON offset printing fast drying does not bear skin of high, medium and low-grade inks for the user choice.
Environmental requirements
In recent years, with the development of economy, environmental label exhibition calls increasingly high, the printing ink circles to offset the non-toxic, non-polluting bring forward new requirements, environmental protection offset printing ink has been widely attention and began to use on the packaging, newspapers, commercial printing, etc. Environmental protection offset printing ink in the United States, Japan and other countries have already won the large-scale application hualian, but in our country, printing the application is still very little, this one technology factors, but the more the main reason is the lack of awareness. Environmental protection offset printing ink main is no aromatics soy ink. Traditional ink contain PAH levels of more aromatic hydrocarbons (ring) is a kind of volatile solvent printing film, harmful to human body; Contain the volatile organic compounds not only increase atmospheric pollution, also can cause harm to human body. Offset printing ink using soy environment-friendly materials of soybean to replace some oil solvents, can reduce the pollution to the environment and human body damage. Tianjin Japan inks Co., LTD of production without aromatics soybean oil (AFSOY) sheetfed offset printing ink, rotary printing ink, thermosetting type has both good rotation ink printing eligibility jiaxing printing, still can meet the requirements of environmental protection, and can provide the corresponding environmental protection certificate. Domestic offset printing ink present market situation in recent years, with the development of the printing industry in Shanghai printing quotation, domestic printing ink industry development step also faster and faster. As a large number of imported and domestic high-speed offset printing machine installation, new prints of the material production, and the printing of new technology and post-press processing the special requirements, printing ink manufacturers relying on scientific and technological progress, and to develop the bo printing the procurement of new products, improve the old products, product variety increasingly rich periodical publishing, product quality is also gradually close to the international advanced level. Ink production equipment update and the improvement of production technology, have gradually by all the attention of the ink manufacturers. Nearly 10 years, tianjin, Shanghai, hangzhou, shenzhen, taiyuan, domestic main ink manufacturers pay attention to collect market information printed materials to meet market demand, and constantly develop new products, such as offset printing ink dry ink, paper light fast printing ink, UV ink, mute powdered paper printing ink (light), news paper printing ink rotation printing ink, cold solid type offset printing ink, and UV ink rotation, offset printing ink, Indian ink synthetic paper in recent years in China and the launch of new hot and solid type offset printing ink rotation is rising year by year, the output of the products of the advanced international level quality stereoscopic printing, the printing by domestic and foreign customers approval. In addition to replace the past in the domestic market of high-grade offset printing inks imported the offset printing ink, of some domestic product also enter the international market. Some high value-added special offset printing ink also have successfully developed, meet the requirements of the special printing. Sheetfed offset printing ink in the domestic market always kept a steady rise the situation with the printing press, printing uv innovation and improvement, domestic sheetfed offset printing ink adapted to the high speed, multiple color, fast drying, efficient and energy saving, and needs, and continue to develop new products, expand the everyday printing in packaging and printing the application fields, such as alcohol and tobacco, food, cosmetics, etc, and satisfy the books "highlights, high concentration" printing and packaging and printing "quick dry friction resistance and the performance requirements of"; Offset printing ink adapt to rotate the rapid growth of the newspaper and commercial printing needs printing Co., LTD, and constantly improve the quality and production. At present, our country offset printing ink manufacture enterprise mainly has: tianjin Japan ink Co., LTD., taiyuan high's larry ink Co., LTD, HangHua ink chemical Co., LTD, Shanghai peony ink Co., LTD and shenzhen deep th inks Co., LTD, Shanghai DIC ink Co., LTD. And Shanghai printing ink si united chemical Co., LTD, suzhou coase wood ink Co., LTD, tianjin pretext chemical group Co., LTD. At present, our country offset printing ink products mainly to offset printing ink, the light fast dry hot and solid type offset printing ink rotation for the leading product printing shenzhen, the second is hot and solid type offset printing ink, UV offset printing ink rotation, synthetic paper offset printing ink, offset printing Indian ink, no water offset printing ink, offset printing ink and all kinds of metal with special ink offset printing. And, the domestic hot and solid offset printing ink, rotation of UV offset printing ink develop more rapidly in the last two years. The gap between the offset printing ink of domestic and overseas similar domestic offset printing ink printing ink, there are still many compared to products deficiency rice paper printing, and can not meet the packing and publishing and printing the demand of the market.
(1) the offset printing ink manufacturing process. Ink production process automation degree, low ink detection method to low level of automation, human factors influence more printing industry press, and the stability of the raw material is bad, cause ink products in quality consistency and stability there still have difference.
(2) the offset printing ink color standardization. International, offset printing ink color standard has a European standards, Japan, the United States such as standard Pantone standard several south China printing, and our country offset printing ink no their color standard.
(3) wide gamut printing ink. In wide gamut of four color ink alternative six color or seven color ink printing press, improve printing quality and can also improve the production efficiency, while domestic wide gamut offset printing ink field needs to be developed.
(4) suit high-speed four color overprint ink. Domestic four color overprint ink in high density and high transparent and XianYanDu and excellent overprint sexual need to be further improved.
(5) environmental protection offset printing ink. At present, China's printing industry printing factory faces great environmental protection, because of printing pressure used in most of the ink all contains organic solvent (and solvent, offset printing ink compared the ink organic solvent rarely) letterpress, organic solvent volatilization and discharge can cause environmental pollution. In addition, the printing ink contains lead, chromium, cadmium, hg, as and barium and other harmful heavy metals, to the body and the environment has great harm. From the Angle of environmental and health and orchestra printing, more and more users in the choose and buy when ink will low-toxic, environmental protection, no pollution as an important condition. In our country, the research and development of the offset printing ink environmental still by numerous factors, but for China printing ink industry as it small printing machine, finally realize and promoting the green ink is development target and final goal.
(6) offset printing ink without water. There is no water do not use embellish liquid version of the offset printing, can say for environmental protection, made great contribution in the last two years is expected to offset printing paper without water in light printing area should have good development space. But there is no water in the actual offset printing ink printing process by environmental temperature influence CD presses, easy up dirty, and still need special offset printing equipment without water. In addition, because there is no water offset printing plate printing more expensive in the domestic, notebook application and promotion certain limits, development more slowly.
Future direction
(1) distance. Along with the offset printing ink yield increase gradually, offset printing ink production process is gradually to automation development direction dongguan, through introducing advanced printing equipment, improve our production process control level, ink Through the increased single batch production to improve ink printing ink quality consistency and stability.
(2) the establishment of China's own offset printing ink color standard. The national printing standardization technical committee and tianjin Japan ink Co., LTD. Establish "national ink (offset printing) printing eligibility standardization test base" in after the first work of, is the establishment of China's own offset printing ink color standard. On October 26, 2007 card printing, the printing standardization technical committee held in Beijing "China offset printing ink color standard established QiCaoZu meeting, tianjin Japan inks Co., LTD, HangHua ink chemical Co., LTD, JinDong paper Co., LTD., which enterprise group company representative of the relevant enterprises attended the meeting, shenzhen HaiChuan company representatives introduced at the meeting" China color system "standard related content. The meeting of "China offset printing ink color standard" and related "China printing paper color standard", "China printing color standard" ideas and line of work to make a preliminary planning printing CD, and on the basis of unit duly organized "China offset printing ink color standard" QiCaoZu by tianjin, Oriental ink Co., LTD. As the main drafting unit for establishment, and from now on related standards in drafting sample collection and experimental verification work. At present, our country's print production standardization are busy. In short, offset printing ink as one of the offset printing printing raw materials, to keep his own advantage a4 printing and absorbs and learn from foreign advanced experience, through the introduction of advanced technology, equipment, high offset printing ink in production, equipment technology printing industry press, improve the level of the offset printing ink, establish the quality and grade of the product standardization, color ink for our country the rapid development of printing ink industry and try hard.
