Ink type small offset printing machine

Fast, simple, cost-effective and reliable We all know that the quality of the print product depends directly on the quality of the ink supply control of the offset press. At present, there are two kinds of ink structures used by small offset press manufacturers in the world and small offset press structures that are circulated in the domestic and international printing markets. One is the separation of ink and ink, and the other is the combination of ink and ink. Which ink-and-ink structure is more reasonable? Industry professionals are divided.
In the ink-and-ink separation structure, the water roller and the ink roller have a specific responsibility. In order to control the water content of the roller, a water fleece sleeve is added on the water roller. In the ink-and-ink structure, the ink roller is generally used as a water transfer task and does not require a water fleece cover. Here we compare and analyze the main advantages and disadvantages of these two structures:
A problem of ink-water balance speed With the development of society and the acceleration of the pace of human life, the concept of rapid printing has been integrated into our daily work and study. The needs of customers are often faster, higher, and better. The ink separation structure adopted by Komatsu Printing Machine is derived from the ink and ink structure of the large offset press. Due to the structural characteristics, a large amount of paper is wasted during the adjustment of the ink and ink balance. The cleaning of the water fleece cover is troublesome. Every time the product is shut down, it needs to readjust the ink balance and use a small offset press with ink and ink structure. The ink balance is high-speed and fast, and it can immediately enter the printing state, that is, saves paper and eliminates the trouble of cleaning the water fleece cover, saving printing auxiliary time. ,Improve work efficiency.
Second, the cost of printing problems The use of ink and ink separation structure of the small offset press due to the use of water fleece sets of water supply, and the water jacket is consumables, be sure to regularly replace. Water fleece covers, as high-value consumables, increase costs and reduce profits. The waste of a large amount of paper in the process of adjusting the balance of ink and ink has added a burden to users.
Third, print quality problems no matter which type of ink structure of the small offset press (except for commercial printing small offset press) to print more than 150I/inch color prints are difficult to achieve, mostly adapted to simple color printing and general black and white printing. Since the printing standards and user positioning are the same, it is sufficient to satisfy the user's requirements. In recent years, with the improvement and perfection of ink-in-one structure, the quality of printing outlets using the ink-and-ink-structure offset printing press has been continuously improved, and the quality of printed products that have exceeded the ink-separation structure small offset press has been achieved or even adopted.
Comparison of performance of two kinds of ink structure

From the comparative analysis of the performance of the above two types of ink structures, it can be seen that both structures have their own advantages and disadvantages. However, at present, the well-known small offset presses at home and abroad, such as Heidelberg, Ebara, and Yoshiaki, have adopted ink-jet structures for the latest products, and they have developed into ink-ink structures. I think that this change in ink structure is nothing more than the following reasons:
First, a small offset press using the ink-and-ink structure has a fast ink-ink balance adjustment, and its performance is fast and flexible, adapting to the needs of current rapid printing.
Second, a small offset press using a water-ink structure eliminates the need for a water fleece cover to reduce commissioning and cleaning time. For users to save a lot of cost, reduce costs and improve competitiveness.
Thirdly, with the improvement of the structure of the ink-ink combination, the quality of the printing outlets using the ink-and-ink-structure offset printing press has been continuously improved, and it has been able to satisfy the need for high-grade printing.
As for the small offset presses that the user chooses, which one is quick, simple, economical and reliable, which one to choose? (Guan Guishan) ("China Packaging News")
