| Flexo Print Originated in the twenties of the 20th | | | | more conducive to the production. 2. Plate material and |
| century the United States. Aniline dyes used in inks | | | | production Should first select the appropriate type of |
| because of their toxic, originally known as aniline | | | | ink used plate, not all plates are suitable for UV inks, |
| printing Flexographic printing has not been developed. | | | | printing plates wrong choice will cause swelling and |
| To the seventies of the 20th century, due to | | | | deformation in the printing process. Plate-making |
| advances in industry, polymer resin Plate , Ceramic | | | | process is also very important time to control each |
| Anilox roller , UV ink and UV drying technology in | | | | step should be just right, light enough to stick |
| recent years to promote the development of modern | | | | excessive, inadequate drying, storage, improper plates |
| technology, flexible version of a qualitative leap. Flexible | | | | will reduce the service life. 3. Roller features First |
| version of the current process is worldwide with the | | | | spinning roller network selection should follow the |
| fastest growing printing process, the Label Industries: | | | | following principles: color separation film of screen lines |
| the U.S. flexo printing in the label area of about 85%; | | | | (lines / inch or lines / m) should be the number of at |
| Europe flexographic printing started late compared | | | | least one roller of 1:3.5, network printing should reach a : |
| with the U.S., the market share of about 45%, and the | | | | 5 ratio. Roller cleanliness is also important, netted on a |
| rapid upward trend. Flexible printing in Asia is currently | | | | regular basis, thoroughly clean the ink transfer can |
| at the initial stage, many manufacturers are launched a | | | | ensure that the amount of ink color matching and to |
| new flexographic printing press. Flexo printing | | | | ensure that duplication of reproducibility. 4. Ink type and |
| technology in full swing, it more than in 2000, Chicago | | | | compatibility, ink system Surface should be used in |
| has also been fully reflected all of the exhibitors | | | | different printing ink corresponding systems, such as |
| unanimously released the latest version or UV flexo | | | | paper, ink, PE, PP, PET, etc. Plastic Film ink, PVC ink, |
| flexible technology and equipment. Even some | | | | aluminum foil material ink, etc.. The choice of ink system |
| well-known equipment suppliers in the past for | | | | failure, or have poor compatibility with ink, ink in the |
| Adhesive Main disappointed resin tag label industry | | | | substrates will lead the team with the surface |
| printing mode, the Chicago Exhibition in 2000, also | | | | properties and strength decline, and even science |
| quietly shifting to flexible version, in particular, UV Flexo. | | | | would lead to h reaction. 5. Corona treatment, surface |
| As technology advances, flexo has gradually entered | | | | coating, UV lamp These factors also affect the |
| a new era. Flexography reason has been great | | | | adhesion of printing ink, the printability of plastic film on |
| development, thanks to its economy and high quality | | | | the printing surface through the corona treatment and |
| features. 1. Color separation film Color separation film | | | | processing coated surface coating layer to increase. |
| version directly affect the quality and printing results. | | | | Surface coated with a variety of chemicals: acrylic, |
| As the use of web flexography spinning roller, roller | | | | vinyl, etc., are solvent-or water-based. Using gravure or |
| arranged at an angle mesh points were tested | | | | flexo process wheel, and its advantages are: no time |
| (currently more than 60 degrees or 45 degrees), in | | | | limits for printing, better wettability and ink adhesion for |
| order to avoid power lines, flexible version of the angle | | | | most of the market, and ink, do not need line of |
| and film screening Offset printing Compared to a 7.5 | | | | equipment and handling, anti-chemical and scratch |
| degree difference. If the film version with the flat-type | | | | resistance, suitable for printing with the speed. |
| exposure system, in the system before the film should | | | | Disadvantages are: costs relative to the finished |
| be based on plate cylinder diameter, double-sided | | | | product in terms of the material by the corona |
| adhesive paste version of the thickness, only the | | | | treatment is more expensive, and corona treatment is |
| thickness of the graphics compression. Should also | | | | used to improve the PE / PP coating of the surface, |
| pay attention to film with the graphics performance of | | | | wetting and binding power of the most common. |
| plate properties match. Film with Polish plates will be | | | | |
