With the rapid development of the color printing industry, the market's demand for four-color offset printing presses is increasing. However, the domestically-made four-color offset printing presses are still unable to fully meet market demands regardless of product quality, stability, or quantity. Therefore, the sales of imported machines, including the two mobile phones, in the domestic market have only increased.
The ink supply and water supply systems for four-color multi-color offset presses are one of the key technologies for multi-color offset presses. The rollers, cleaners and maintenance supplies provided by Bottcher in Germany provide very important technical support for solving this problem. . According to foreign experts, one of the main reasons for the gap in print quality between the new offset press and the second mobile phone in Heidelberg is that the second mobile phone is not equipped with high quality rubber rollers after repair.
The water supply system of a multi-color offset printing press is currently an alcohol dampening system, which has the advantage of reducing the amount of water when the ink is added after the addition of alcohol, thereby reducing the deformation of the paper, reducing the emulsification of the ink, and improving the printing product. Registration accuracy and the color of printed products.
The water supply method of alcohol dampening is a multi-point water supply. The advantage of this method is that the equipment is relatively simple; the other method is multi-point water supply. The advantage is that different pH values ​​can be adjusted for the water supply of different color groups to meet The need for different color inks. In order to solve the environmental pollution caused by alcohol, alcohol substitutes have emerged. However, the alcohol dampening system requires high rollers, and Bottcher can provide high-quality rollers for the alcohol dampening system to ensure stable and reliable operation of the system.
The multi-color ink supply system requires the ink roller to have sufficient micro-porous surface, reasonable elasticity and hardness, and ensure continuous and stable ink transfer. Bottcher has its own rubber smelting plant with modern processing and inspection equipment that guarantees the physical and chemical properties of the roller, plus the company's supply of detergents and maintenance supplies to ensure the quality and longevity of the roller. .
At present, domestic manufacturers of offset printing machines can provide four multicolor machines to the market: Shanghai Guanghua Printing Machinery Co., Ltd., Qingdao Radio III Factory, Jingdezhen Printing and Packaging Machinery Corporation, Hunan Printing Machinery Factory, and Beiren Group Corporation. Qingdao Radio III Plant is a 25-series four-way starter that introduced Solna Co. of Sweden, and purchased all technologies including the original customer market. The model originally used Bottcher's rubber rollers. The four boot series products of Shanghai Guanghua Printing Machinery Co., Ltd. absorbed the experience of Heidelberg, and it is very likely that Bottcher products will be used in the ink supply system, while the products of Hunan, Jingdezhen and Beiren are mainly designed by themselves.
For the convenience of customers, Bottcher has specially provided the manufacturer with the business of hanging plastics in Germany, that is, the roller core provided by the user, and the plastics coating, processing and inspection according to Bottcher's standards. Due to the high price of the German roll cores and the user's own supply of roll cores, the cost of the roll is greatly reduced, thus providing greater possibilities for the use of the world's most advanced Bottcher roll. In order to improve the quality of ink supply and water supply systems for home-made four-open offset presses, we recommend:
First, the design of the ink roller and the water roller should move closer to Bottcher's products because it is the supplier of rubber rollers for almost all famous international offset press manufacturers. In this way, it is beneficial to the versatility and interchangeability of domestic parts after the domestic offset press has entered the international market, and it is particularly advantageous for overseas customers to purchase after-sales service for Chinese products.
Secondly, the products provided to the domestic market can be provided with both domestically-made and imported-type rubber rollers for user selection. Users can make their own decisions based on the needs of different printing products.
Third, in the domestic four-color multi-color ink supply water supply system in the important position of the selection of imported rubber roller, and the general location of the use of domestic rubber roller, so that it can not only increase the cost, but also improve the stability of the system Reliability, but also improves the product's reputation.
The use of advanced technologies that can be utilized by all countries abroad will enable our country’s existing multi-color machine technology to achieve leapfrog development, and narrowing the gap with the international advanced level will accelerate the pace of our technological progress. This should be our country's design and production. An important concept for people. In short, we hope that the domestically-built multi-color offset press will continue to improve quality, consolidate the domestic market, and enter the international market.
