The pad printing is to transfer the pattern carved on the steel plate onto the workpiece through the action of the pad printing rubber head, after the pad printing rubber head contacts with the pattern, the pad printing rubber head is dipped with the printing ink with the corresponding pattern, and then the pad printing rubber head is covered on the workpiece, so that the pad printing is completed, and the pad printing is similar to stamping in daily work.
Because different inks have different display effects, after some inks are contacted with the pad printing rubber head, the inks need to be kept stand in the air for a period of time to be contacted with the product, and after printing is finished, the inks on the pad printing rubber head need to be wiped off, otherwise, the subsequent printing use is affected.
