Metric printing digital device

The invention provides a metric printing digital device. The metric printing digital device comprises a main board, printing mechanisms, carry mechanisms and positioning mechanisms, wherein the main board is round; the multiple printing mechanisms are arranged, the printing mechanisms are uniformly fixed on the main board around the circumference of the main board, and the printing mechanisms comprise digital wheels capable of achieving mobile carry; the carry mechanisms are fixedly arranged on the back side face of the main board, are in one-to-one correspondence with the printing mechanisms,and cooperate with the digital wheels in a pulling mode; and the positioning mechanisms are fixed on the main board, are in one-to-one correspondence with the digital wheels, and cooperate with the digital wheels in a clamping mode. According to the metric printing digital device, the digital wheels are used for replacing track plates, so that use of resin plates is greatly reduced, plate makingtime and plate pasting tim
