Everyone is confused about how to choose a pad printing head before printing?

Generally, the printing effect of a relatively pointed rubber head is more beautiful, but if it is too sharp, it will deform when printing a large pattern. Therefore, a rubber head with a gentle tendency will reduce the printing distortion. At the same time, if the speed is controlled, the printing effect will be more beautiful. The printed effect is more perfect.
The hardness of the pad printing rubber head shows the ability of the rubber head to resist compression deformation. In printing, a softer rubber head can achieve larger deformation, which is suitable for printing materials that are not very regular. It is best to choose a softer rubber head, which can Combined with printed products, the deformation of harder rubber heads is relatively small, and the expansion of dots during printing is also small. It is used for printing flat printing materials or color dot patterns. For finer printing patterns, you can also choose harder rubber heads. The printed text and patterns will not be deformed.

The service life of the pad printing head is closely related to the usage rate of the product and the depth of the ink and steel plate.The pad printing rubber head is subject to wear and tear during repeated printing. With elastic deformation, cracks appear. Generally, if the printing pattern is not very good, it should be replaced.
Regarding the relationship between rubber heads and inks, pad printing rubber heads often complete printing during the process of transferring ink and solvent. It is recommended not to print poor inks and solvents during the printing process. The same is true for printing steel plates.Good ink is good for the rubber head, ink and printing effect.
The shape of the rubber head and the size of the pad printing rubber head should be compared with the pattern to be printed, and they should be just right. If the rubber head is too large and the pattern is too small, it will cause waste.The pressure on the machine also increases, and different printing products require different rubber heads.
If it is found during pad printing that the installation position is too biased, the friction force is too large or too small, etc., the center position of the rubber head of the pad printing machine should be adjusted appropriately.
