  • What Are the Main Advantages of Flexographic Printing? 21-01-17

    Flexographic printing  1. Simple equipment structure, easy to form a production line. In offset printing, gravure, flexographic printing equipment in the three major flexographic printing machine is the simplest structure. Therefore, the price of flexographic printing machine is relatively low, the printing enterprise equipment investment less. At the same time, because the equipment is simple, easy to use and operate, easy to maintain. At present, the vast majority of flexographic printing machine, with such as soup gold, varnishing, cutting, slitting, die-cutting, creasing, punching, window and other processing line, forming a production line. Greatly improve labor productivity.  2.A wide range of applications and substrates. Flexo printing can print almost all printed materials and use all substrates. Especially in the packaging printing of corrugated paper printing has a unique this.  Offset Printing Offset printing is mainly used for the printing of paper-based materials. Printing on plastic film has many limitations. Sheetfed offset printing machine printing width can be changed, more flexible. At present, the vast majority of web offset printing machine printing width is fixed. Its application is limited. The development of technology, web offset presses are constantly improving. Now has been successfully developed to change the printing width of the web offset printing machine. At the same time, the successful development of seamless roller web offset press.  The printing cylinder of this web offset printing machine is seamless, in this regard has been the same as the web gravure printing machine. Offset presses also continue to improve on the printing function. With the improvement and addition of some parts, it is possible to print corrugated board. With the improvement and addition of UV drying device, it is possible to print UV printed parts. The above improvements continue to expand the use of offset presses in the field of packaging printing. Offset printing with water-based ink will soon enter the practical application. Here offset printing is another step. Gravure printing Gravure printing, ink full of three-dimensional sense, in a variety of printing methods, the printing quality is the best. And printing quality is stable. Long life of the printing plate. Suitable for large quantities of printing. Gravure printing can print very thin materials, such as plastic film. However, gravure plate making is complicated and expensive, and its benzene-containing ink pollutes the environment. These two problems have affected the development of gravure printing. In particular, the reduction of a large number of large number of prints, short version while requiring a large increase in low-priced prints, so that gravure printing continues to lose market.

  • Why Choose Digital Flexo Printing Plate? 20-12-28

    Flexographic printing is suitable for all kinds of substrates and has a wide range of applications. It is used on corrugated boxes, Tetra Pak, flexible packaging, labels, folding cartons, paper bags, paper cups, napkins, playing cards and other printing and packaging products. What is the difference between digital flexo printing plates and ordinary flexo printing plates? 1. Scattering and diffuse reflection is different The scattering and diffuse reflection of light in the exposure process is different, ordinary flexo plate in the exposure, ultraviolet light to pass through the vacuum layer, film base, emulsion layer and anti-halo layer, its total thickness is large, there are a more serious scattering and diffuse reflection problems. And digital flexo plate in the exposure, the light only through a layer of less than 0.001in the thick black coating, there is only a weak scattering and diffuse reflection phenomenon.     2. Exposure environment is different Ordinary plate making is exposed under vacuum conditions, while the digital printing plate is exposed in the air. Photopolymerization resin in the air and in the vacuum of the photopolymerization reaction mechanism is different, resulting in the printing plate dot shape, exposure tolerance and other properties of the printing plate is also different.   3. Point shape is different Dot reproduction range, ordinary flexo plate raised dot cross-section is round, the longitudinal section is trapezoidal, and the top of the dot flat, while the digital flexo plate raised dot is relatively small, and the tilt is small, the top of the dot is round, but not flat. The dot edges of flexographic plate for flexo printing are more rounded. And the edge of the dot on the ordinary flexo plate is clearly contoured. Clearly, contoured dot printing is easy to break the scratch, and the digital flexo plate on the dot, especially the high light point is not easy to appear in this situation, so the printing quality is good.   4. Different exposure tolerance The black coating on the digital flexo plate greatly improves the tolerance of the main UV exposure. Experiments show that the digital flexo plate main exposure time increased by 5 ~ 10min, the image on the printing plate part of the height of the bump without any effect, while the ordinary flexo plate is different, as long as the exposure time has a small increase, it will make the height of the graphic bump significantly reduced.  Exposure tolerance is conducive to the perfect shape of the dot. Because the digital flexo plate has a certain exposure tolerance, so there is no need to pay special attention to the highlight and dark tone points during exposure, but also to ensure that the highlight points are not lost and the dark tone points are not pasted. It is recommended that the main exposure time of the digital flexo plate is 10min, which is sufficient to ensure that the highlight point is not lost. In the production of the ordinary f...

  • What Do You Know about Digital Flexo Plate Making Machine? 20-12-31

    Principle of Digital Flexo Plate Making Machine When making a plate, an infrared laser emitted by the image generator of the digital flexo plate making machine ablates the black absorption layer of the text portion, exposing the photopolymer resin layer underneath. Since the photopolymer layer is insensitive to infrared radiation, the emulsion layer is not affected by the laser ablation.  After laser ablation, the printing plate is fully exposed. The black coating in the blank area of the printing plate blocks the light so that the photopolymer layer in the blank area is not sensitive to light; while the photopolymer layer in the graphics area loses the protection of the black coating and undergoes a photopolymerization reaction, which forms the part of the final graphic. After exposure, digital flexo plates can generally be developed in the usual way, namely: solvent washing, drying, and finishing. However, some digital flexo plates need to be rinsed with water to remove the black coating before they are solvent treated. Exposure type of digital flexo plate making machine Digital Flexo Platesetters have two types of exposure: inner cylinder exposure and outer cylinder exposure. In the inner cylinder digital flexo plate making machine, the plate is kept on the inside of the cylinder during the exposure process; in the outer cylinder digital flexo plate making machine, the plate is kept on the outside of the cylinder during the exposure process. When the cylinder rotates at high speed, the exposure head moves laterally relative to the cylinder to expose the plate. At present, the flexo direct plate making machine is basically an outer cylinder, only small or medium-sized (30in, 40in) plate making machine has an inner drum. Digital flexo plate making machine is controlled to work by a Raster Image Processor (RIP). The RIP is the hardware or software that interprets the data coming from the front end of the computer and sends it to the laser typesetter. The RIP of an inner cylinder digital flexographic plate maker is interpreted in the PostScript language. It works on the same tasks and principles as the PostScript laser typesetter. It describes and interprets the page content sent from the application, creates a dot matrix image, and controls the laser ablation of the digital flexo plate making machine to record the page information on the plate. The raster image processor consists of two parts: the interpretation part and the control part. The interpretation part receives page information from the computer and encodes it for the control part; the control part is used to control the operation of the imaging system. The domestic digital flexo plate making machine manufacturers, represented by Suzhou Ollide, have been highly praised by domestic users for their high-quality products, price advantage over imported equipment, and perfect after-sales service. Olid, as a company engaged in the business of aniline printing plates, color photo paper, a...
