Kompac automatic wetting system makes the offset press even more powerful

Professionals in the industry all know that the quality control of offset press water supply directly determines the quality of printed products. From the perspective of the water supply control structures adopted by the world's small offset press manufacturers and the water supply control structures of small offset presses circulating in the domestic and international printing markets, most of them are ink-and-ink separation structures or ink-and-ink structures. Is there a better way to control water supply? The Kompac automatic wetting system provided by Yingkou Guanhua Offset Co., Ltd. in cooperation with the United States VARN company will give you a refreshing look.
The Kompac automatic wetting system is a system that provides automatic ink balance for offset presses. The Kompac automatic wetting system consists of a water roller, a measuring roller and a series of water rollers. Measured dampening liquid is stored between the water roller and the measuring roller, and the dampening effect is achieved by supplying the plate fountain solution through the water roller. A part of the ink on the image portion of the printing plate is transferred to the water roller and the measuring roller through the water roller. Under the great pressure of the water roller and the measuring roller, the transferred ink is torn and emulsified. A very thin wetting layer forms afterwards. The role of the skewer roll is to distribute the emulsified ink more evenly. Since the emulsification takes place between the water roller and the measuring roller, this does not bring some of the emulsified ink to the ink source table, and at the same time replenish part of the ink for the next transfer. When the plate cylinder is turned to the notch position, excess wetting fluid formed on the water roller will flow back to the water reservoir along the edge of the water roller.
The Kompac automatic wetting system is a three-roll system for the continuous supply of wetting fluid. The dampening fluid is supplied to the printing plate by a watering roller. The watering roller is driven by the plate roller gear. Because there is a speed difference on the surface of the printing roller (relative sliding) ), so when installing the Kompac automatic wetting system to offset presses, every installation requirement must be carefully adjusted.
The Kompac automatic wetting system automatically replenishes ink onto the plate cylinder when the ink film on the plate image splits and transfers. This is mainly due to the emulsification of the ink. Offset machines equipped with the Kompac automatic wetting system are superior to general wetting systems in printing large areas of solid, fine dots, halftones, and anti-whitening.
Advantages of Kompac Automatic Wetting System:
1. The speed of water balance adjustment is fast, reducing trial printing waste. Experiments have shown that mature printers save 30 minutes of test time per day.
2, reduce paper waste. Experiments have proved that the trial printing paper can save more than 50%, and there is no waste in shutting down or shifting the speed. The average annual saving is about 50,000 sheets or more.
3, quick start - continuous process. Every week, the water balance is automatically calibrated and there is no need to adjust the water balance. Basic guarantee that the first print is the same quality as the last print.
4, automatically ensure constant water supply. After the Kompac automatic wetting system is installed and adjusted, it can be ensured that the amount of water supply in each printing is stable and the water film is uniform, which helps to improve the quality of printed products.
5, increase the proliferation of ink film, and enhance the uniformity and clarity of printed products.
The biggest feature of the Kompac automatic wetting system is that the ink balance is faster when printing large areas of color, and the system has automatic compensation for offset ink supply. At present, internationally renowned manufacturers of printing presses, such as Heidelberg, Ebara, Yoshiaki and others, are adding Kompac automatic wetting systems provided by VARN to improve product performance and improve product market competitiveness.
Thanks to the application of Kompac automatic wetting system, the structure of the water supply control part of the small offset press can be replaced, which improves the quality of the printed product and reduces the user adjustment process, providing a new path for reducing the difficulty of product production and processing.
