Flexographic printing label

shift to flexographic printing label

rker is one of the largest independent label manufacturers in the UK, and won the "best label Award" in the 2002 Academy of Packaging Awards. The award-winning product is a label container innovated and developed by the company. It can be placed in a microwave oven for heating, and the outside is still kept at room temperature after taking it out, so as to avoid the misoperation of other personnel. It is expected to be applied in food packaging

recently, the company has equipped ist UV curing system on a newly purchased seven color and eight color Nilpeter fa3300 printer to ensure that the products produced by the company meet strict standards and the needs of the future food packaging market

the use of thinner and thinner plastic printing materials means that heat management is the main issue to be considered when purchasing printing machines. The most important thing for printing with flexographic press is to configure the correct UV curing system. In the past, this company had some problems in heat control, especially the new printing machine needed to print some very thin films and foils, which was of particular concern. In the daily packaging market, Parker company produces 20million yogurt cup covers every month, 24 hours a day, 7 days a week. Therefore, the reliability of printing machine and UV curing system is very important. The new UV system should also be flexible, so that it can easily handle printing materials with different thicknesses. When the printing process is shorter and shorter, it can also be adjusted quickly. For the Nilpeter printer with ist MBS UV curing system installed with water cooling roller, it can be fully competent for these jobs

after testing, install the UV curing unit with water cooling roller and set the water temperature to 18 ℃, which can ensure the minimum heat load on the surface of the printing material during the curing process

Parker company has been established for 52 years and has 15 years of experience in using UV printing. It specializes in producing high-quality food and daily-use packaging for major supermarkets in the UK. Until a few years ago, including profiles, pipes and plates, which have entered a stable growth period, the company only focused on offset printing. A few years ago, through a visit to Nilpeter company in Denmark, the technology of UV flexo printing began to change. Seeing the products produced by the UV flexo printing technology of Nilpeter printing machine and their achievements, the company decided to enter the flexo printing market. In the two years after that visit, the company replaced all the original offset presses with three Nilpeter flexographic presses

the production manager with 20 years of production experience said that he had been completely attracted by UV flexo printing technology and was deeply impressed by the improvement of UV flexo printing quality. "With the new system, we have to ask designers to adopt higher requirements for UV flexo printing products, because we can now successfully print on the thinnest unsupported film and the latest packaging plastic without any overheating or distortion."

he also said that compared with offset printing, the biggest advantage of flexo printing is that it can print on unsupported film. If the traditional offset printing technology is used, it is simply impossible to avoid registration problems. If flexographic printing is used, there is no problem with poor wear resistance printing even on the thinnest film

this is becoming increasingly important as food packaging labels tend to use thinner films. The application of shrink film provides a broader market for the company. Printing on unsupported shrink film only 15 microns thick will not cause any registration or overheating problems. Using ist UV system on the new printing machine, even if printing on 400 micron thick three-layer thermal cardboard, there will be no problem

according to the development trend of packaging labels, plastic labels tend to be used in the food packaging label market, which affects the company's investment strategy. Three years ago, 80% of the company's products were printed on paper and 20% were plastic prints. At that time, it was believed that the market would tend to use plastic, so it focused on the technology of printing on plastic. At present, 70% of the company's products are printed on plastic, and only 30% are still paper

the latest label products are getting thinner and thinner, usually only 36 microns or 45 microns thick. Therefore, for food packaging manufacturers, the most important thing is heat control and management

in order to meet the future requirements of food packaging, printing companies should provide full process label packaging and printing services, including label printing, sleeve and cover making, bump rolling, and die cutting. Supermarket suppliers only need to contact one printing manufacturer and check the whole process of their packaging production, rather than twoorthree. This is the "one-stop packaging process" service. Customers only need to come once to see the whole packaging process of their products

exquisite film labels

James Townsend, with a 137 year history, is one of the largest independent label printers in the UK. Recently, it has made a major investment in the latest technology in the UV flexo printing market and purchased two MPs ep510 flexo printing machines equipped with ist UV curing system, which are specially used to print film labels for the beverage market. Continuous development guarantees continuous success, and they have always been proud of it

more than 100 employees with an average length of service of 16 years have also made important contributions to the stability and professional development of the company

this company is famous for its quality and service in the UK, and it is also one of the first printers to realize the importance of UV glazing to improve quality. Since 1985, ist UV curing system has been successfully used in offset press

in the beverage market, the trend is to use thin and transparent film to print labels, which prompted the company to enter the UV flexo market. It looks like a packaged product without labels, and the clean and refreshing feeling is very popular in the market

The manager of the company said that they have been paying attention to the development potential of flexo printing and how the bottled beverage market in the United States got involved in UV flexo printing seven or eight years ago. The problem is that the quality of the United States is not enough for the British market, that is, in recent years, UV curing technology can finally meet the stringent requirements of British supermarkets

with the continuous improvement of UV flexo printing technology, it means that it can meet the requirements and standards put forward by customers, and the company quickly and successfully expanded its business to the field of flexo printing. In just six months, the production manager and the quality and technology manager selected three printing machines. One is an eight color MPs ep510 flexographic press. Its printing unit and paper receiving unit are equipped with a full set of ist UV curing system, which has strong flexibility and operates like a lithographic press, which is very helpful for employees to switch from operating a lithographic press to a flexographic press. This flexographic press is equipped with an air-cooled UV curing system. Combined with the cold mirror reflection technology, it can ensure that the thermal load on the film is as low as possible. Combined with the cooling roller provided by MPs, it can effectively control the heat, and can completely print ultra-thin thermal materials without reducing the printing speed. When the printing speed reaches 130 m/min, there will be no curing problems. The quality of flexographic printing has been greatly improved in recent years. When sending flexographic printing samples to customers, they often mistakenly believe that it is lithographic printing

the company won five awards in the first year of flexo printing, including the first participation in the best work award, a highly respected international flexo outstanding achievement award and two gold awards

in June, 2002, the second 10 unit MPs printer was installed, which was still equipped with the same UV curing device. The company may purchase a third flexographic printing machine in recent years to further expand its investment in flexographic printing

entering the field of flexographic printing will not bring any damage to the reputation of companies famous for quality and service. Flexographic products will win awards for their quality like lithography, and there will be no discount on quality and customer service

fast label printing

illochroma company in France produces flexographic labels in large quantities. At present, the use of UV technology provides a reliable technical guarantee for its mass label production

the company was originally specialized in offset printing. In 1996, it purchased a Canadian Argyle flexographic machine and began to engage in flexographic production to print 23 inch label products. After more than three years of continuous testing and testing, flexo printing production business has expanded rapidly, and now flexo printing production has achieved the expected profits. Yajiafa flexographic printing machine has been produced day and night, and 6 flexographic printing workers with 4 × 8 shifts

both water-based ink and UV ink are used on the machine. These inks are usually used in printing operations that require fast and aging resistance. Water based flexographic ink can obtain better color, but it is not suitable for long-term printing, because the agglomeration of ink will lead to the fouling of the printing machine. The use of UV ink is more flexible, and it has excellent scratch resistance during transportation. Water based ink can produce brighter color patches, while UV ink is a little dim, but it can be used for very fine silk printing. Therefore, if the price of the same experimental machine varies greatly, the printer must operate according to the performance parameters of different inks, so as to obtain the best printing effect

95% of labels are printed on transparent or white polypropylene film (25 ~ 100 microns thick), on which there is only a thin layer of ink. Generally speaking, the printing speed of water-based flexo printing can reach 80 m/min, while the speed of UV flexo printing, or the speed of water-based and UV mixed ink can reach 130 m/min, or even 200 m/min, but this depends on the curing speed

this rotary printing machine can print 7 (or even 8) colors and is equipped with 10 printing units. The last two units are usually used for some special processing, such as glazing or bonding. For UV flexo printing, the machine is equipped with five ist water-cooled UV curing light boxes (BLK type), as well as 200 w/cm light tubes and cold mirror reflection technology. For water-based flexo printing, hot air oven can be used to dry the ink. Two uncoiling devices, one for printing and one for laminating. When it is necessary to print on the back of the label, a turnover device will be installed before quality inspection and final die cutting. According to the customer's requirements, the label is delivered to the customer after being formed by drum or die cutting. CTP resin plates provided by subcontractors (BASF or Asahi) can greatly reduce the degree of dot enlargement and improve the quality of printing

this French company produces labels for many manufacturers, some of which require more and more special labels. Some prints must be completely polished to avoid the leakage of some components, or the scratch resistance of labels can be enhanced by lamination (paper film, film film). From the perspective of the future, they are paying attention to these two applications and other fields. They have also studied in detail, such as high brightness UV glazing, or fragrance glazing labels (microcapsules)

illochroma printing company in France is a branch of illochroma label group. The group has 1060 employees in seven production bases, and produces 30 ~ 35million labels every day. The annual output is about 75billion, and the total production capacity is 90billion. The products are beer labels, glue labels for water and beverages, pet food labels, etc. more than 70% of the labels are produced in Europe, and the rest are exported to all parts of the world, from Russia to South America. ※
