Waterless printing outstanding performance in five aspects

Waterless printing is more prominent in the five aspects:

1. Excellent printing quality

(1) Copying images is more realistic. Waterless offset printing plate "target="_blank"> The flat and gravure structure of the plate can effectively control the dot gain. At the same time, there is no need for fountain solution in the printing process, and there is no screen for ink emulsification problems, making the dots more clear. Water offset printing, even if the number of screens is only 175lpi, can fully reproduce the changes in the tone of the print.

(2) can greatly improve the overlay accuracy and production efficiency. Overprint accuracy is an important criterion for evaluating print quality. In the waterless offset printing process, since no fountain solution is transferred to the paper, the chance of swelling of the paper fibers can be greatly reduced, especially in water-sensitive materials such as rice paper, writing paper, and tissue paper. Very high overlay accuracy. At the same time, for double-sided printing, the impact of water is twice as large as that of single-sided printing. If there is no influence of the fountain solution, the accuracy of registration and the printing efficiency will be greatly improved.

In addition, in the prepress area, waterless offset printing also eliminates the need for various process changes for the overprint problem, thereby improving the production efficiency.

(3) Has a stable color density. Waterless offset printing process is not interfered by the fountain solution, making the ink transfer more smoothly and stereoscopically. The ink transfer is more stable and can be printed at a stable density, thus ensuring the consistency of the printed product.

(4) can adapt to various types of printing materials. Waterless offset printing does not use fountain solution, expanding its choice of printing materials, so that a variety of films and synthetic paper and other substrates with poor water absorption can be selected printers, this advantage has also attracted many UV printing customers.

2. Good environmental protection

Environmental issues are one of the most important issues facing the world today. Waterless offset printing has reduced VOC emissions by 60% to 80% compared to traditional offset printing, significantly reducing the environmental impact. The VOC emissions of traditional offset printing and waterless offset printing in a workshop are shown in Table 1.

3. High economic efficiency

At present, although the price of waterless offset printing plates and inks is slightly higher, the expense of fountain solution can save a cost standard and certification, and the equipment maintenance costs associated with the fountain solution and waste water discharge treatment costs can also be saved. Secondly, the offset accuracy of waterless offset printing is high, which can effectively reduce the time for registering, reduce waste sheets, and improve the printing efficiency screen, which is highly economical.

4. Suitable for cross-regional management and standardization implementation

With the expansion of the business of some companies, the difficulty of cross-regional management is getting higher and higher. The local production environment, the characteristics of raw materials, and the capabilities of first-line production employees are not the same. It is very difficult to make the same product with the same printing quality. Waterless offset printing only requires the establishment of standardized temperature and printing pressure, which can ensure the consistency of printed products, and is suitable for cross-regional management and standardization implementation.

5 can reduce the operator's technical requirements

At present, the printing industry lacks a high level of professional and technical personnel. If operators do not need to pay attention to ink and water balance, as long as they are fully concerned about printing overprinting, the company can cultivate more and more skilled operators in a short period of time to ease personnel shortages. The problem.

In general, waterless offset printing technology is a kind of printing method that can improve printing quality and environmental protection. With waterless offset printing technology, printing companies are expected to further improve the standardization management level and increase their overall competitiveness and industry influence. Therefore, the financial crisis, waterless offset printing has a broad space for development, especially with the increase in the importance of environmental protection and print quality, I believe that waterless offset printing technology will also be accepted and applied by more and more printing companies.
