Web printing aids

When used in conjunction with other production processes, web offset can achieve maximum production value.

The quality of web offset printing has never been doubted, and its cost price has hindered the use of this process. However, a new generation of web offset printing equipment has been greatly improved. It can be used with offset printing or other printing processes to obtain higher quality at a lower cost. Due to its online capabilities and speed advantages, it is believed that web offset printing will soon be adopted by more printers.

Participants at the Labelexpo exhibition last year witnessed examples of transitions to multiple processes. For example, RDP Marathon has focused on the LF series of variable-length web presses that can be used interchangeably with offset, flexo, screen, waterless, and gravure hybrid printing equipment.

Due to the flexibility of this printing method, an appropriate printing process can be selected according to the requirements of each printing job - four-color printing offset printing, special coating printing flexo printing, high ink deposition screen printing, with Gravure and so on with a metallic effect.

Nilpeter, a company that produces hybrid web offset printing, recently introduced the first-generation 20" M-5200 of the 13" M-3300 series. These presses feature a platform slide-in system that allows the cartridge to be replaced without the use of tools, as well as off-line print preparation. The important feature of this equipment is the ability to change equipment settings from one job to another. Nilpeter has UV flexo and UV screen printing capabilities as well as lamination, embossing, bronzing, and die cutting.

Offset printing can be well integrated with UV flexo printing, while UV flexo printing offers greater printing coverage and better on-site ink coverage. Brandtjen & Kluge Company regards the latest UV flexo performance provided by the company's web offset printing system as the most significant development in the company's printing press production. Because this can greatly expand the production range of the printing press.

Investigation of Improvements Recently, web offset printing has become more and more closely related to sheetfed printing and is widely known. The marketing director of Heidelberg's Speedmaster 102 sheetfed presses believes that online technology including printing, hot gold foil stamping, pasting, and die cutting gives the company the opportunity to find new, scalable customers.

Initially, Heidelberg has been hesitant since the focus of rotary offset printing is on long-lived and difficult-to-replace printing plates. Now, the Gallus TCS250 intermittent web printing press is ideal for short and medium-sized live business, and supports both lead printing and silk printing. Web printing is entirely suitable for individual printing modes. Since the TCS250 requires format-independent attachments, the overhead of special components is reduced.

Printer manufacturers are ready to make many changes to the press. Printers have many special needs. Many people need more colors and more special colors. There are also demands for special layers and high resolution. Therefore, Stevens has been working hard to improve the accuracy of the company's web management system. Moreover, on some models of equipment, Stevens also added a larger roller to the ink supply system to reduce fogging.
