1) Can pad printers use UVLED inks?

The use of UV inks is the trend of all printing processes. Its environmental characteristics, the glossiness of the ink itself, and the flexibility of operation have inspired pad printer manufacturers to develop pad printers that use UV inks. Since the ink layer of pad printing inks is thin, but it requires high adhesion, this has restricted the penetration of UV light. For a long time, the high concentration and opacity of pad printing inks have hindered the mature application of UV pad printing inks. Today, this situation has changed. Special UV resins, easily penetrable pigments, and the matching of UV light have made great progress. If you want to use UV inks, there are basically no technical obstacles.

2) Why should pad printers be equipped with automatic pad cleaning devices?

The deinking property of the pad transfer ink is a prominent feature of silicone rubber, but the adsorption of the rubber itself will still leave a certain amount of ink, which will affect the printing quality. At present, more advanced pad printing machines will be equipped with pad cleaning devices to automatically remove the ink on the surface of the pad to improve the printing quality. The cleaning device can be cleaned continuously or at intervals.

3) Can pad printers use cylindrical pad printing rubber heads?

Pad printers mostly use conical and rectangular pad printing rubber heads, but cylindrical pad printing rubber heads can also be used in special occasions, such as printing long strips of products or printing cylindrical products. At this time, the cylindrical pad can rotate under the drive of the motor to transfer the ink to the surface of the product. The cylindrical pad is similar to the silicone rubber roller of the thermal transfer machine, but it does not need to be resistant to high temperatures.

4) What are the extensions of the pad printing rubber head's movements?

The shapes of products that pad printers need to print are becoming more and more complex. Some products require the pad printing rubber head's movements to be extended to complete, such as requiring the rubber head to be able to print deep into the inside of the rice cooker; some pad printers require the rubber head to have three-dimensional movement deflection, and some pad printers require the rubber head to perform complex movements like a manipulator. On some assembly lines, the pad printing rubber head must be able to be set at any angle according to the printing position of the product.

5) Will pad printers be replaced by inkjet printers?

Inkjet printers are controlled by computers and do not require plate making processes. They have absolute advantages in personalization and color enrichment. They have a serious impact on pad printers, screen printers, offset printers and other printing fields, but it is impossible for inkjet printers to replace pad printers and screen printers. On the one hand, the ink of inkjet printers is difficult to replace the saturation and expressiveness of printing ink colors. On the other hand, the ink of inkjet printers is also difficult to replace printing inks in terms of diversity. The tolerance of pad printers to product appearance is also unmatched by inkjet printers, so pad printers and screen printers will not be replaced by inkjet printers.

6) What are the main advantages of using servo drive for pad printers?

Servo drive is mainly composed of servo motors and screws, and its accuracy is unmatched by pneumatic pad printers. For multiple pad printings of the same product, the accuracy of the servo pad printer is 1.5 times that of the pneumatic pad printer. The mechanical parts driven by the servo basically do not have positional shaking, and their wear is also very small. In addition, the servo-driven pad printer has greater pressure. Under the conditions where greater pressure is required or greater pressure needs to be maintained, only the servo pad printer can do it. The servo pad printer can also achieve complex movements, and can also cooperate with the screen printer and hot stamping machine to achieve multi-process combination printing.

7) You can use both pad printers and screen printers. How would you evaluate their advantages?

The ink layer of screen printers is thicker than that of pad printers, and the color expression is stronger and more uniform in the direction of the ink layer expansion, while the ink layer of pad printers is thinner and shows a uniform decreasing trend in the direction of the ink layer expansion. Pad printers usually occupy a smaller space, and the production process of pad printing plates is relatively simple. In the case of using both pad printers and screen printers, the choice should be based on the customer's requirements and your own conditions.

8) Why do pad printers use resin plates?

Some European customers will require pad printers to install resin plates, which is a requirement of pad printer users for environmental protection. The principle of installing resin plates is similar to that of installing thin steel sheets. However, the printing durability of resin plates is lower. The traditional method of making steel plates involves corrosion by strong acids, and the residues will cause certain pollution to groundwater. The production process of resin plates mainly uses water and alcohol, which basically does not pollute groundwater. This is the main reason why Western countries with strict environmental protection requirements prefer to use resin plates.
