Printing is one of the special printing methods. It is capable of printing text, graphics and images on the surface of irregularly shaped objects and is now becoming an important specialty printing. For example, the text and graphics on the surface of the mobile phone use this printing method, as well as the surface printing of many electronic products such as computer keyboards, instruments, meters, etc., all of which are completed by pad printing.
The pad printing process is very simple, using steel (or copper, thermoplastic plastic) gravure, using a curved head made of silicone rubber material, the ink on the intaglio plate is rubbed onto the surface of the pad and then to the surface of the desired object. You can print words, patterns, etc. by pressing it.
There are often many printing failures in the printing process. This paper summarizes the common faults in the printing process and organizes them into a more comprehensive printing failure.
One of the common faults: the lines and text of the printed matter are unclear and blurred.
The second common fault: the adhesion of the ink does not meet the requirements
This fault is very common in pad printing because you don't know the formula of the ink, or the type of ink you choose is incorrect.
The third common fault: obvious pinhole shape on the printed matter
If the small pinholes are large and appear in the same position on the print, check the image on the pad and the intaglio. Replace the pad and gravure if necessary.
