Web offset printing presses are increasingly favored by people because of their extremely high production efficiency, but because of their own weaknesses, they are limited to the field of publishing and printing. For packaging and printing, due to the invariability of the size of the packaging box, it is difficult for the rotary offset press to exert its advantage of high production efficiency in the field of packaging and printing.

To solve this problem, many printer manufacturers have adopted plug-in technology. The so-called plug-in technology is to make the plate cylinder, blanket cylinder and impression cylinder on the printing press into an independent component, which can be removed as needed. In this way, several inserts with different cylinder sizes can be made according to the size of the printed matter. However, this technology still has unsatisfactory features. First of all, the cost of making a plug-in is relatively high. If the size of the print is too large, the cost of the plug-in will be higher. Secondly, the plug-in is relatively heavy, and it is laborious and time-consuming to replace. Although it has been repeatedly improved, it is still very cumbersome. In addition, since the rotation of the drum needs to be driven by gears, the diameter of the drum cannot be arbitrarily designed.
The emergence of sleeve technology makes printing of different sizes of prints more flexible, but when replacing the sleeve, the transmission gear must also be replaced, and the size change cannot be changed steplessly.

The emergence and application of shaftless drive technology has greatly improved this situation. After the rotary offset press uses shaftless drive technology, all the axes are driven by servo motors. In other words, the printing plate cylinder, blanket cylinder and impression cylinder are driven by independent servo motors. Due to the elimination of the transmission shaft and transmission gear, the shaftless drive offset printing machine can realize the stepless change of the size of the printing plate and print the printing materials of different thicknesses.

It can be said that the perfect combination of the simplified technology and the shaftless drive technology has changed the situation that the rotary offset press is limited in the length of repeated printing, and set off a new revolution in the offset printing market. Drant-Geber is the first manufacturer to apply shaftless servo motor technology to a rotary offset press. Its concept of VSOP (Variable Sleeve Size Offset Printing Technology) enables printing plates and blankets to be installed in The sleeve made according to the length of the printing piece has the characteristics of light weight, easy operation, fast replacement, high flexibility, and wide range of printing materials.

At present, in the packaging and label market, the competition of various printing technologies is very fierce. In the short version printing, rotary offset printing has an advantage over gravure printing and flexo printing. First of all, the offset printing plate can be done immediately, and it has excellent performance in screening, gradation, minimum dot size, fine lines and text. Secondly, for different types of printing materials, such as cardboard, labels and films, if gravure or flexo printing is used, the requirements for plate-making are different. However, if offset printing is used, the replication curve and printing quality are the same for different printing materials. In addition, when printing on different substrates, offset printing also has great advantages in terms of color consistency. Therefore, in today's printing volume is getting less and less, the price is getting lower and lower, rotary offset printing will have more markets and opportunities, and, with the new materials such as direct plate making and seamless rubber blanket The successful development of web offset printing will usher in a broader development space.

Lanyard

Lanyard

1.What is lanyard:

A lanyard is a cord or strap that is worn around the neck to hold an identification badge, whistle, keys or other small object. You can see lanyards in use everywhere by businesses, schools, hospitals, at special events, conventions, reunions, and in many recreationall activities.

2.Lanyard Category:

Based on different material used for lanyard production, here are five kinds of Zipper: Heat Transfer Lanyard , Silk-Screen Lanyard , Silicone Lanyard, Zipper Lanyard and Jacquard Lanyard.

2.1. Heat Transfer Lanyard

Sublimation Lanyard is designed in the pattern, production copperplate, electric carving through the mechanical sub-color pattern engraved on copperplate. Copperplate printing machine and then get on the pattern printed on the PET film, and then through the mechanical heat transfer lanyard pattern is transferred to the product.

Sublimation lanyard content can be product brands, publicity posters, slogans, may also be sporting events, concerts, commercial activities, the name and other gatherings LOGO. Nylon, cotton, bamboo fiber can not withstand high temperatures, and high cost to go through a special process to heat transfer lanyard.Such as custom Printed Lanyard,double hook lanyard.

2.2. Silk-Screen Lanyard

Silk webbing lanyard is the production process LOGO traditional common expression, LOGO is printing ink by screen printing on the surface of the webbing. Printing out of LOGO texture clear, strong sense of three-dimensional, high definition, good adhesion.

Generally can be divided into screen printing lanyard phone lanyard, U disk lanyard, MP3 lanyard, working lanyard, lanyard exhibition, documents cards sling, brand badge lanyard, badge lanyard, lanyard visit visitors Wait. Product brands, publicity posters, slogans, may also be sporting events, concerts, commercial activities, the name and other gatherings LOGO.

2.3. Silicone Lanyard

Silica gel is silica gel mSiO2 · nH2O made of a suitable dehydrating porous materials of different particle sizes. Has an open porous structure, specific surface area (surface area per unit mass) is large, can absorb many substances, it is a good desiccant, adsorbent and catalyst supports.

Silica gel lanyard using silica gel as a material made of, but not limited to mobile phone ornaments, can be widely used in MP3, MP4, digital cameras, small flashlights and other products of the match.

2.4. Zipper Lanyard

Zipper lanyard and zipper is shaped the same,It is the perfect companion for the mobile phone, brand certificate, key ring. Beautiful and practical zipper manufacturing plating with laser engraving and other advanced technology refined elegance applicable Peigua digital cameras MP3 U disk, PU rope, PVC rope, zipper cell phone rope, rope, harnesses, hand Wan belt.In addition to metal beads, other materials can be printed corporate LOGO logo, and in different parts and assembly methods, play publicity, promotional purposes. According to customer needs, design and manufacture many styles, diverse fashion lanyard!

2.5. Jacquard Lanyard

Jacquard Ribbon Ribbon is a high-grade varieties.

Jacquard Ribbon generally used for high profile clothing materials or decoration materials (such as curtains, sand release material). Jacquard manufacturing process complicated. Warp and weft interwoven ups and downs, to form different patterns, convex, more weave flowers, birds, fish, insects, animals and other beautiful patterns.

Jacquard Ribbon soft, delicate, unique and smooth texture, good gloss, good drape and breathability, color fastness (yarn dyeing). Weft jacquard pattern amplitude with large and beautiful, color structured three-dimensional sense, and by the Jacquard pattern is relatively simple, relatively simple.
