The image processor compares the standard image with the real-time image. If the real-time image is different from the standard image, it is determined that the embossing position is offset, and the embossing position deviation is displayed on the human-machine interface, and then the corresponding Aa value offset X is calculated; when the offset X is not equal to zero, the image processor sends the offset X to the master control module, and the master control module sends an instruction to the automatic deviation correction module to drive the paper guide rail C to move, and the paper guide rail C drives the rolled material to move the stroke X; thereby correcting the a value to the specified range. If this offset X lasts for a specified time and has no tendency to decrease, the master control module will send a signal to stop the device and display the embossing position offset on the human-machine interface. Adjustment steps: The master control module receives the embossing position displacement transmitted by the image processor, sends an adjustment instruction to the automatic deviation correction module, and adjusts the paper guide rail accordingly.
