For a long time, the flexographic printing industry has continued to focus on higher quality and productivity. Therefore, in the investigation process of global flexo users, an unexpected conclusion was obtained. Most of the survey participants believed that the ink transfer in the field was needed, and at the same time, the printing plates of the dot printing were taken into consideration; most of the respondents also indicated that Fast coloring is equally important for faster printing speeds. In the plate making shop, users are looking for plates that are reproducible and have better print quality. In addition, they are also concerned about the improvement of plate making efficiency.
Flat-top outlets have the ability to increase solid density and improve dot tone, which helps to enhance the competitiveness of flexographic printing. In recent years, there have been a variety of technologies for flat-top outlets on the market. All technologies have a certain degree of complexity and require additional equipment or materials at the front end. All of these technical improvements have been somewhat cumbersome to date. In the discussion that follows, this article will delve into a new technology that will make plate making and printing easier.
Problems with flat top outlets
Traditional laser versions offer excellent gradations and highlights. However, there are also many people who believe that the value of a flat-top dot is that it can achieve 1:1 dot reproduction, better tone reproduction, and a more realistic to high-light gradient. These features attract users to adopt flat-top dot technology, but many people find that the process of using flat-top dots is not smooth.
In the first issue of flexo journals more than a decade ago, Andy Kanulpati and Brad Taylor of DuPont Packaging Imaging Department carefully described the sharpening of the dots observed during the standard digital platemaking process, and Explain its mechanism. Most manufacturers of plate and plate equipment in the industry have tried to solve the problem of flat-top outlets by understanding the mechanism of dot formation. There are several solutions on the market, including the use of film or separator film after the main exposure; there are technologies using high-energy LEDUV lamps, and DuPont's technology for exposure in inert gas environments. . All of these technologies can achieve flat top outlets. But they all require extra steps or extra investment in the plate making equipment.
Easier solution: Cyrel® Easy Technology Platform
DuPontTM Cyrel® Easy technology is a built-in flat top dot function in the plate. Users only need to expose the air in the same way as the ordinary laser version to make a flat top dot plate. Plate makers don't need to change the way they used to be, as long as new technologies are used to solve past problems, so making flat-top outlets is a breeze. At the same time, the Quality of the Easy series is also very good. Because when the process of laminating is removed, the human factors cause no errors, the plate making quality is more stable, and there is no need for additional equipment upgrades such as LED tubes.
The Cyrel® Easy technology platform improves the technical process of making flat-top outlets, and it can also be combined with other innovative technologies such as thermal technology, matte surface technology, and field screening technology to make it perform well on the press. This gives flexo users the ability to create new quality and efficiency records in the lab and print shop.
If a user gets a more uniform field using field screening technology, this seems to be a perfect solution, but because some companies do not have physical screening technology, it will bring some pre-production challenges. A plate with a flat top dot and a matte surface solves this problem. Nowadays, when the same user chooses the Cyrel® Easy plate, the plate with a matte surface can be used without having to rely on the in-situ screening in the prepress stage to improve quality and productivity. For those who are pursuing sustainable development goals, for example, some are reducing or limiting the use of solvents, combined with the technology of flat-top dots and thermal technology is a viable solution. In this way, flexo companies improve quality, productivity and sustainability in production operations.
