HCMoog has long been collaborating with well-known press manufacturers such as Albert-Frankenthal, MAN, Goebel and Johannisberg, and has accumulated extensive experience in reels and sheet-fed gravure printing machines. In 1948, HCMoog developed Holbein, a special sheet-fed gravure printing press, which was purchased by many well-known printing companies in England. The Holbein press has a stacked structure that is very close to the current offset press and uses the mechanical principle of offset printing.
First, the sheet-fed gravure printing machine In 1986, HCMoog company carried out a comprehensive and thorough update design of the gravure printing machine it produced. The drum-type transfer system replaces the chain paper transfer system. This new type of transfer system uses a double-diameter cylinder, which greatly facilitates the handling of rigid substrates (specific gravity up to 400 g/m2). The roller cock located between the printing units has applied for patent protection and can guarantee the work flow of sheet-fed paper. The length, width and diagonal direction of the sheet material are controlled by the press console. Once the control value is set, once the control value is set, only two prints are needed to achieve accurate registration of the printed matter, and the consistency of the registration will be maintained throughout the printing process, and the operator of the printing press need not worry about it. Therefore, this sheet-fed gravure printing machine can greatly reduce waste and reduce scrap rate compared with gravure gravure printing.
The gravure printing machine uses a modern drying method, which is very efficient. In multi-color printing presses, there is a drying system between each printing color group, capable of performing hot or cold air drying on the printed matter so that the previous color ink on the printed matter can be sufficiently dried before entering the next color group. According to the actual conditions and needs of production, either solvent-based inks or water-based inks, or UV inks can be used.
In 1997, Moog introduced a far-infrared (IR) dryer and launched the world's first intaglio printing machine using far-infrared (IR) dryers. Once this printing press was introduced, it caused a great deal of success in the industry. Strong response. So far, there has been a three-color gravure printing machine with far-infrared drying method installed and put into operation in Greece. According to reports, using this drying method can save 60% of energy. In terms of UV drying technology, the company is currently conducting experiments. The inks used by Akzo Nobel and Sicpa Aarberg were used in the tests, and the tests were conducted very smoothly and successfully.
When printing high-end packaging products on substrates such as plastic films, metal foils, and metal foils, the quality of printed matter is the most critical and important factor. The ink layer obtained after printing with the Moog Inc. intaglio printing machine is thick and uniform and can be dried quickly. Since the amount of ink provided is four or five times more than offset or flexo ink, a thicker ink film layer can be obtained. The use of metallic inks and fluorescent inks (the pigments used in these inks generally have a marble-like luster) The prints are bright and glossy. In addition, printing a large area of ​​gold can also print very fine golden text.
In general, high gloss inks contain a certain amount of heavy metal pigments, while high gloss inks produced by IriodinR are nonmetallic inks. Printed with this ink can have pearls, gold, copper, or The bronze-like shiny surface provides users with a new choice. Although these inks are made from non-toxic, harmless natural materials that can be recycled and reused, they can give printed products a high-gloss metallic effect. This kind of fluorescent ink was first widely used in the cosmetic industry with high profit margins, which made the surface of the package have a silky luster and was elegant and soft in color. It just reflected cosmetics (such as lipstick, lipstick and nail polish). The natural color of itself. At present, these inks have also been widely used in cigarette packaging, food packaging, labels, and security printing, and can effectively prevent counterfeit copying.
Second, electrostatic static equipment (Electrostatic Print Assist)
As a method and means to improve and maintain the consistency of print quality, electrostatic auxiliary equipment has been used in rotary gravure for more than 30 years. The loss of dots is very detrimental to the quality of continuous tone prints. Under the effect of electrostatic charge, the ink in the platen roller can be completely transferred to the printing material, so the loss of dots can be avoided.
Not long ago, static-electricity aids could not be used on sheet-fed gravure presses. This is because the structure of sheet-fed gravure printing presses is similar to that of offset presses. The embossing roll cannot transfer electrostatic charges to the embossing site, and the paper roll is Teeth can cause a short circuit in the system. On the contrary, under a printing pressure of 80 kg/cm2, the impression material is pressed at the embossed portion with a double circumference impression roller, so that the dot is lost.
At Drupa 2000, Moog demonstrated a practical electrostatic assist system designed specifically for its sheet-fed presses. The system was successfully developed by Moog and Spengler Electronic AG of Switzerland. It conducted thorough and detailed tests and tests at Gestel. This static electricity was installed on all of the company's five-color 740 x 1040 mm presses. auxiliary system. Therefore, when purchasing a new type of press from Moog, the customer is free to decide independently whether to equip such an electrostatic assist system.
Third, the machine structure Moog TBR's sheetfed gravure printing machine can have up to eight printing color group, four formats (from 520 x 740 mm to 1040 x 1440 mm), the maximum printing speed can reach 12,000 per hour.
Mr. Kurreck, chairman of Moog, has been engaged in gravure printing for many years. He believes that gravure printing cannot be compared with any other printing process in terms of the stability of production and the brightness of print colors. At the same time, he also acknowledged that flexographic and offset printing processes also have their own advantages and strengths. Therefore, he advocated the implementation of a combination printing process in production to meet the needs of customers in the most effective way.
In the case of Gestel, for example, when printing multi-color jobs, it is common to first perform multi-color printing on an offset press, and then go to a gravure press (manufactured by Moog Corporation) for finishing and glazing. Alternatively, another method can be adopted, that is, Moog's standard gravure printing machine is assembled with a flexographic printing unit to perform on-line production and quick replacement of the job.
Fourth, the label In addition to packaging, Moog's gravure printing machine is also widely used in the printing of labels, in order to achieve higher quality standards, often using gravure and offset printing off the assembly line of the two ways (that is, not connected Combination) to print jobs, this production method is very favorable for short-lived printing with stricter registration requirements. For example, at Gestel, cigarette packs are packaged using a combination of gravure and offset printing; Tonutti of Italy also likes to use this combination printing process to print labels; French Buriot companies often use a combination printing process to print Liqueur (liqueur) label.
A label printing company that uses expensive metal foil, which is subjected to embossing and embossing, as a substrate material, may have the opportunity to use plain white paper in the future, and it can also print on plain white paper by gravure printing. Metal or non-metal background color, gold or opaque white, and then overprint the image with offset printing, then you can also use the gravure process for embossing, embossing can be freely selected, for example, along the diagonal direction Still along the length direction and so on.
Finally, a water-based varnish is printed on the label surface. When the container is recycled, this varnish can be easily rinsed off with water. This is one of the outstanding advantages of this combination process. When metal foil is used as the printing material, the metal layer can also have a certain protective effect, so as to avoid tearing the label from the product easily.
V. Future and future of sheetfed gravure printing machine Mr. Kurreck said: “The future of sheetfed gravure printing machine is bright. From a technical point of view, flexo and offset printing have almost reached the peak and limit of their respective development. , they can only increase a little bit further forward, while the gravure is not the case, with the application of electrostatic printing support system, product quality has been greatly improved, gravure printing process has also made great progress, we can have exactly one A big leap forward.†Using an electrostatic assist system, printing companies can also print higher-quality prints on paper and paperboard with poor quality, even on the rough surface (ie, non-printing surface) of the substrate materials. There will be no loss of outlets. In offset printing, due to the constant cleaning of the blanket, a certain amount of production time is occupied and wasted. However, the single sheet concave printing press does not have this problem. Therefore, the production time can reach almost 100%, and the production efficiency is better than offset printing. The machine is 30% higher. A sheet-fed gravure printing machine with a printing speed of 12,000 sheets per hour is comparable to an offset printing machine with a printing speed of 15,000 sheets per hour, and the gravure printing machine can also be used at the end of the production line. The prints are tested.
Although the current printing tasks are usually distributed throughout the country and even around the world, the printed images on the packaging and labels must be exactly the same wherever they are printed. This puts forward the need for off-site printing and off-site printing technologies. Certain challenges. The application and growing popularity of Internet technology has provided a good solution for this, through the network can transmit the live data to a remote destination, and then use these data directly engraving plate roller, the quality of the plate is almost the same as the local. It is worth mentioning that the first printing technology that actually applied direct printing technology was a gravure printing process, which also greatly improved the quality of printed matter and greatly shortened the platemaking cycle.
Sheet-fed gravure printing machines manufactured by HC Moog GmbH are known for their higher print quality. The Austrian national printing company and the Dutch company Gestel have adopted their gravure printing machines, among which the Austrian national printing company has printed. The exquisite stamps won the praise of people all over the world, and the packaging of cigarettes, cigars and candy products printed by the Dutch company Gestel is also deeply loved by the people of the world.
