Waterless offset era is coming

With the strong admiration of people in the industry, waterless offset printing technology has achieved great development in the early 1990s. In the waterless printing process, people's concerns about the balance of the inks are eliminated, the volatilization of the harmful gases of the VOC/HAP is reduced, and the printing ability is strong, which seems to be quite perfect. However, people are still not satisfied with the status quo of waterless printing. For example, Toray, the sole holder of a patent for a simulated waterless version, is constantly developing to meet the growing demand. The long downtime of waterless printing makes many printers unwilling to use waterless offset printing, and the monopoly of the printing plate market has also affected new users.

With the continuous efforts of suppliers, the future development of waterless printing may soon change. Matik North America's sales department represents Codimag's new Viva 340 press. They believe there is a lot of potential for waterless printing. Toray's monopoly of waterless printing plate patents will not be too long, the price of printing plates. Will fall, waterless printing inks will also have greater practicality. Sanki also looks forward to the future of waterless offset printing. The company's new presses can provide waterless printing, and can also carry out appropriate post-press processing, including cold laminating, hot/cold bronzing, etc. All operations are Completed within a working cycle.

Another closely related to waterless printing is the heat generated during the drum grinding of the ink. Equipped with an important part - online temperature control system can maintain a constant temperature and ensure the stability of the ink viscosity. Therefore, Viva 340 uses separate cooling circuits on the ink path and UV drive devices, and also uses a separate plate cylinder cooling device.

However, improvements to conventional web offsets can greatly reduce the use of waterless printing. Brian Ivens, RDP Marathon’s international marketing manager, believes that unless there is a special printing application, companies will gradually see the decline of waterless printing. He said to the new user that the improvement of the area covered by the roller on the web offset press and the material of the blanket has made great progress in solving the problem of ink and wetting. He also believes that the increasing complexity of process performance has compensated for quality defects, making the quality of waterless printing no longer a prominent advantage.
