ABSTRACT:
Prepared is a transcribing plate comprising a glass substrate and a chromium film formed on a surface of the glass substrate. The transcribing plate is disposed on a surface of an object (for example, a glass substrate of a plasma display panel) such that the chromium film faces the surface of the object. The transcribing plate is pressed toward the object, if necessary. A predetermined identification code pattern is drawn on the transcribing plate by a YAG laser beam. The laser beam reaches, through the glass plate, the chromium film to heat it. Chromium vapors generated by the heating are deposited on the surface of the object. This means that the identification code pattern is transcribed on the object surface.
