1. How to choose a pad: Generally, the printing effect of a sharper pad is more beautiful, but too sharp will deform the printing of a large pattern, so a pad with a slower inclination will reduce the printing distortion. At the same time, if If you control the speed. It will make the printing effect better.
2. Softness and hardness: Hardness shows the ability of the pad to resist compression deformation. In printing, a softer pad can obtain a larger deformation. It is suitable for printing product that is not very regular. Choosing a softer pad can combine pad with printed products. The harder pad has less deformation and smaller dot expansion during printing. It is used for the printing of flat prints or chromatic dot patterns. For finer printing patterns, you can also choose a harder pad.
3. Use life: The life of the pad is closely related to the usage rate of the product, the depth of steel plate ink. The pad is worn by the repeated printing process, and cracks appear with elastic deformation. Generally, if the printed pattern is not very good, it should be replaced.
4. The relationship between pad and ink: Pad is often printed during the process of transferring ink and solvent. It is recommended not to print bad ink and solvent during the printing process, and the same is true for printing steel plates. Good ink is also good for pad and printing effect.
5. The shape of the pad: the size of the pad should be compared with the pattern to be printed, and it must be right. If the pad is too large and the pattern is small, it will cause waste and increase the pressure on the machine. Different printing products require different pads.
