Misunderstanding of anilox roller

When it comes to anilox rollers, here we have to point out that there are many kinds of anilox rollers and they are widely used. Apart from the anilox rollers used for printing, there are anilox rollers for coating and polishing. Here we only have Talk about flexo printing anilox roller.
When interviewing Secretary-General Lin, he outlined the types and development process of the current anilox roller. He said that there are two kinds of anilox rollers commonly used in flexo printing. One is a metal anilox roller, which is mainly used for printing corrugated cardboard, because the accuracy of printing on corrugated cardboard is not very high, in addition to the layout of more text and lines Can also be used metal anilox roller; the other is ceramic anilox roller, which is divided into two kinds of integral and sleeve type, mainly used for printing high-end products. Ceramic anilox rolls were produced in Europe in the 1980s and were introduced in China almost during that period. It can be said that the high-quality anilox roller belongs to the category of ceramic anilox roller, which is divided into a specific range according to different quality levels.
1. What is high quality What is a high-quality anilox roller? For this issue, several experts have basically the same answer.
Shanghai Ao Keli’s returnees believe that:
First, to see the accuracy of the anilox roller, the higher the precision, the higher the grade.
Second, it depends on the quality of the ceramic layer on the ceramic anilox roller, that is, the density of the ceramic layer is good or bad. Speaking of this point, Genggeh played an analogy very vividly. He said that the semi-finished anilox roller after ceramic coating is like wood. The harder the wood is, the better it is to be carved. The more loose it is, the less likely it is to be carved and shaped. The same applies to the roller. For the anilox roll, the density of the ceramic layer refers to the porosity, and the smaller the better, the pore size per unit area is usually less than 1%. In addition, spray equipment also affects the quality of the anilox roller.
Third, we must look at the level of laser engraving. The control of the volume of the cyberpockets, the depth of the cyberpockets, the shape of the cyberpockets, etc., is determined by the sculptural links.
Lu Ji of Shanghai Laser Group also believes that while ceramic anilox rolls are now commonplace, it is not to say that they are high quality products. The so-called high quality should meet the following requirements: The quality of the ceramic coating is good, and the parameters such as finish, uniformity, mesh shape, and mesh volume of the carved out cells are conducive to transfer and use. Secretary-General Lin also emphasized the maximum amount of ink stored, he said, "I think the high-quality anilox roller should be the same kind of line number, the kind of ink storage is also the largest, which requires the processing of anilox roller, The depth of the cell site should be as deep as possible, and the surface finish should be as high as possible, so that the service life will be longer and it will be a good product."
2. Misunderstanding of high line counts The evaluation of the basic parameters of the anilox roller product will not change, but will only change as the user's requirements increase. We learned from our interview that due to the increasingly sophisticated requirements of flexographic products, the high number of anilox rolls has become the current trend of the flexo printing market. Lu Gong of Shanghai Laser Group stated that “the number of high-line anilox rolls currently produced is 1500 lines per inch or less, which is generally concentrated at 800 to 1500 lines/inch, but our company’s users do not have such a requirement and generally only require About 1,000 lines/inch can be used, and almost all domestic users think that an anilox roller of 600 to 800 lines/inch is enough to meet the printing requirements, and the so-called high line count cannot be based on the ability of the producer side. Demand, there is no sense for the products without the market.” Secretary-General Lin reminded the user, “It is now required that the number of anilox rolls must be high while at the same time they must have an ideal amount of ink to pass. Some anilox rolls, though It can reach 1200 lines/inch, but there is no transmission of ink when it is used.” Therefore, users and manufacturers can not only be stuck on the surface of the high number of lines, we must proceed from the use of related parameters of the product, truly high Number of lines, high quality.
