Abstract
In the marking method and apparatus, a printing plate which is mounted to a plate holder is moved horizontally and vertically and set above a workpiece. The printing plate is then lowered quickly until it comes into contact with the workpiece upon which printing is performed and then, based upon a signal from a detector which detects such a contact of the printing plate to the workpiece, the printing plate is further lowered slowly a predetermined fixed distance. Thus, even if the thickness of the workpiece is different from workpiece to workpiece, the pressing-in amount of the printing plate into the workpiece can be constant for different workpieces.
