<p><P>PROBLEM TO BE SOLVED: To provide a laser marking device where the search for the optimum printing conditions is facilitated. <P>SOLUTION: A storage is stored with test conditional information composed of laser output value and scanning velocity, and test coordinates information regarding each test printing position Pn in which the distance from the optical axis center C of a convergent lens 13 is made almost equal (test radius R2). Then, test printing data are created based on the test conditional information and test coordinates information, and, by printing based on the created test printing data, the test marks MT of different printing conditions (the laser output value and scanning velocity) are formed at each test printing position Pn in which the distance from the optical axis center C is made almost equal. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
