Pneumatic pad printing machine is widely used at home and abroad because of its simple structure, convenient operation and stable movement.
2. According to the classification of printing color number, according to the different printing color number completed in a printing process, the pad printing machine can be divided into single color pad printing machine, double color pad printing machine and multi-color pad printing machine, etc
Multi color pad printing machine can be divided into shuttle type and conveyor belt type multi-color pad printing machine according to the different transmission mode between different colors.
