Powder spraying technology

In the 90s of the 20th century, it was honored as the era of powder science in the world. During this period, high-quality color films, color video tapes, tapes, and other products came into being according to the development of powder technology, which enriched people's lives. entertainment. The printing industry is no exception and the blessings of powder technology advancement are not uncommon. This article describes the application of dusting imaging technology.

Status of Color Printing in Photo Office Environment

In today's office environment, the requirements for color printing are on the rise. However, the status quo is that color printers with a balance between cost and performance have not yet been commercialized, and they are still dominated by monochrome printers. Although the popularity of the Internet, the advancement of calculators and intelligence technologies, and the expectation that offices are going to be paperless, the current reality is that the amount of printing paper in the office is increasing. Moreover, it is highly desirable to obtain the required document types, on-demand printers that can immediately arrange for printing, and a versatile device that can take into account copying and faxing. In order to pursue higher-quality documents and data, it is necessary to seek ways that can be matched with existing black-and-white printing presses and achieve higher printing speeds and cost reductions. The color printing using dusting technology is described below, indicating that it is possible to comprehensively solve the above problems. In the near future, this technology is expected to become the mainstream of printing equipment in the office environment.

Spray printing structure

The following four items can be achieved by dusting.

1. Comprehensive color printing 2. High-speed printing 3. Cheap and little working capital 4. High quality

Dusting is a direct printing in which a toner is directly ejected onto a recording medium such as paper. It is completely possible to quickly obtain stable, high-quality prints at low cost.

The dusting printing structure is as shown in FIG. 1 , and the charged toner is ejected through a fine-pored thin substrate (FPC) toward a back electrode to which a high voltage of 1 KV is applied, and adheres to the paper passing between the FPC and the back electrode. For the fine holes arranged on the FPC, a ring-shaped electrode is provided, and the toner is sprayed on the toner by controlling the voltage thereof with an exciter, and the toner adhering to the paper constitutes a fine dot, which is attached to the ring electrode passing therethrough. The dots form words and images together, and then, like the laser printer, the toner is fixed on the paper by pressure and heat, while the FPC is cleaned in preparation for the next printing.
