Automatic printing machine with calibration function and calibrating method for automatic printing machine

The present disclosure provides an automatic printing machine with an automatic calibration/compensation function, which includes a machine body, a conveyor belt, an image identifying module, a controlling module and a printing module. The conveyor belt is disposed at the machine body. The image identifying module is disposed on the machine body. The controlling module is signally connected to the image identifying module. The printing module is disposed on the machine body and is signally connected to the controlling module. At least one calibrating article is transmitted forwardly by the conveyor belt, and the at least one calibrating article is printed by the printing module. The at least one calibrating article is transmitted inversely back to the image identifying module for getting a calibrating image of the at least one calibrating article. The calibrating image of the at least one calibrating article is then received by the controlling module for a calibrating analysis. Therefore, the error can be red
