Label printing is a very demanding industry for printing technology, materials, processes, and equipment. Variety of labels has various requirements for corresponding technologies.
The label is divided into adhesive type and self-adhesive type. On the label's powder, it is divided into flat type, curved type and contraction type. The printing materials used in labels are more diverse with different paper products, different plastic materials and composite materials. The above characteristics determine that the label printing industry is a very demanding industry for printing technology, equipment, processes and materials. Therefore, when talking about printing technology for label printing, it is often inseparable from the materials and processes involved.
In the printing methods currently used for label printing, various printing methods such as offset printing, gravure printing, flexo printing, and screen printing are applied. Sheet-fed offset printing technology has been commonly used in ordinary adhesive labels but it is the market for flexo and gravure on different printing materials such as plastic materials and composite materials.
Offset web offset printing is a new force entering the label printing market. Offset web offset printing machines of the past were difficult to intervene in this market due to their inability to adapt to changing market demands for label printing. Delander-Geberel's offset printing technology has completely improved the flexibility of the offset printing roller in terms of roller size, and the printing size can be arbitrarily changed, so that the past printing of rotary gravure and flexo printing is also the same on the offset printing rotary machine. Can print. Offset printing is the most popular printing method, with good quality f, cheap printing plate, fast printing speed and other advantages are always the dominant technology in the printing industry.
Compared to sheetfed offset presses, rotary offset presses have the following advantages:
First, webs are cheaper than single sheets. In Europe this difference is between 8% and 15%. Second, the web does not have to leave a special area for the crepe like a sheet-fed press. This saves paper. The paper does not have to be cut beforehand and the paper does not need to be dusted during printing. Rotary printing is used. Humidity has no effect on the printing and storage of paper. The speed of the rotary press is more than twice that of the sheet-fed press, and it can be printed on both sides of the printing machine. Compared with the single-sided printing, the speed is not changed and the production efficiency is doubled. In addition, rotary printing can also be linked with post-processing to greatly increase production efficiency.
Compared with gravure and flexo printing machines, web offset printing can save a lot more time than gravure printing and flexo printing in the aspects of plate making and plate changing. Offset printing plate production can be easily achieved, but also in the screening, gradient, the minimum dot size and fine lines and text have excellent performance. At the same time, the replacement of the printing plate of the offset printing rotary machine can be completed within a few minutes. This also makes the advantages of the offset printing rotary printing machine in short printing.
In addition, Dylante-Gebel's servo drive technology can increase or decrease the length of printing by 1% during printing. This feature is very beneficial for the printing of printing materials such as plastic materials, which are very easily deformed, depending on the material shape. The change adjusts the print length. Even if the material is changed in size, it can be guaranteed that the overlay printing accuracy is stable. This function can only be achieved with the use of servo-driven printing presses, as the servo drive can be precisely controlled, allowing different printing units to run at different speeds.
In the current label printing market, the demand for technology is becoming higher and higher. A single printing method is far from satisfying the pray of the market. Products that use a variety of different printing technologies on the same print are often found on the market, such as the use of both gravure and offset printing on the same print, or offset printing plus flexo glazing for special effects. The use of servo-driven technology makes this printing method very easy to implement. That is, the advantages of various printing technologies can be fully utilized without the loss of production efficiency.
For example, offset printing is advantageous in continuous image adjustment, gradual layering, fine text, and line printing, but it is not as good as gravure and flexo in field printing. Gravure printing is very suitable for printing metallic inks. Flexo printing also has its own unique features in glossing. The Drenthe-Gebel press can combine these offset, gravure, flexo, and even screen printing units on the same production line. After completing this complex printing process, the company can perform inline processing.
The uniqueness of Drenthe-Göbel technology is the combination of servo drive technology and sleeve technology.
Drandt-Gebbel is one of the first manufacturers to apply shaftless servo motor technology to offset printing rotary machines. Its shaftless technology is also different from other printing machines that use shaftless technology. A common servo-driven shaftless printer is driven by a separate motor on each printing unit. The advantage is that there is no shaft drive distortion of the drive shaft caused by the lengthening of the drive shaft, resulting in overprinting faults. However, gear transmission is also used between different rollers in the same unit, which limits the change in the size of the rollers.
The latest servo technology from Dylantz-Gebel GmbH drives all cylinders by servomotors. That is to say, the plate cylinder, the blanket cylinder and the impression cylinder of the printing press are respectively driven by independent servo motors. Compared with the conventional offset printing rotary press, this driving method cancels the transmission shaft and cancels the transmission gear. At the same time, Drandt-Gebel applied flexo sleeve technology to the offset press. Therefore, it can easily achieve infinitely variable plate sizes. The repeat printing length of the Drenthe-Gebel printer can be infinitely variable between 381 and 762mm. The cancellation of the gear transmission makes it easy to adjust the distance and pressure between the rollers. Its advantage is that it can print different thicknesses of printing materials. The thickness of the printed material of the printing press ranges from 10-350 um. It can print paper, cardboard, plastic materials and composite materials on the same printing press. Use servo drive technology to improve the printing accuracy of prints. The offset accuracy of the Drenthe-Gebel Offset rotary press is up to 0.01 mm. It does not detract from the sheet-fed press. In addition to label printing, it can also be adapted to the printing of various packaging boxes. In terms of roll width, customers can choose from 6 different sizes depending on the needs of the roll width 520-1250mm.
The materials used for label printing are numerous and varied, and good results are printed on many materials. Drying technology is very important. According to different requests, Drenthe-Gebbel can use a variety of drying technologies on its presses. Like the most advanced UV drying technology and electron beam drying technology. These latest drying technologies are used. This makes it possible for offset printing machines to print a variety of different substrates. Therefore, printers using these advanced drying technologies can print a variety of papers and print materials such as plastic film materials and other composite printed materials. In particular, the emergence of offset presses in the field of label printing can meet the higher requirements of customers for fine-print quality f-label printing. At the same time, due to the use of the latest drying technology, the printing speed of the printing press has been greatly improved. Like a printer using UV drying technology, its maximum speed can reach 400m/min, which is unmatched by other printing presses.
In terms of environmental protection, both the European and American markets and the domestic market are increasingly demanding environmental protection for printed matters. In the case of prints, customers have been clamoring for reducing the odor of ink. The latest UV drying technology and the application of electron beam drying technology have also made great progress in eliminating the odor in the oil so that the printed matter is more in line with the requirements of environmental protection, and can also meet the stringent requirements for food hygiene on printed matters.
In summary, the offset printing rotary press has an outstanding quality, efficiency, adaptability, etc. It should be the best choice for label printing equipment.
