Pad printing achieve the transfer process mainly through pad , so the printing process is limited by the performance and the shape of the
pad. pad has the following characteristics:
(1) flexibility;
(2) arc;
(3) can not be infinite;
Therefore, it can judge the rough outline of the printing range printing from the pad characteristics , that can not print large patterns.But it is ideal for uneven workpiece with certain patterns, some other printer can not achieve the result.
