step 1: aligning a card feed channel of the multi-axis steering positioning assembly with a channel of the transport assembly; transferring a card from the transport assembly to a designated location of the multi-axis steering positioning assembly;

step 2: variable laser image printing: based on the angle of the grating, the multi-axis steering positioning assembly rotates the card along the axis of the short side at the angle same as the grating angle, and meanwhile, the card moves upwards according to the grating angle and the position of the grating on the card, so that laser is focused at the position of the grating, and after the card moves in place, laser etching printing is carried out by starting the laser, and variable laser image printing is completed;

and step 3: multiple laser image printing: based on the angle of the grating, the card is rotated by the angle with the same grating angle along the long-edge axis by the multi-axis steering positioning assembly, meanwhile, the card is moved upwards according to the grating angle and the position of the grating on the card, so that laser is focused at the position of the grating, and after the card is moved in place, laser etching printing is carried out by starting the laser, and variable laser image printing is completed.
