1. A method of scribing a graphic on a work piece, comprising:
- applying control information from a controller to a laser to scribe a surface of a work piece with laser output that has a power in the range of approximately 500 W to approximately 50,000 W, wherein the laser is moved at a relative laser scan speed in the range of approximately 10 m/s to approximately 50 m/s, and lases the surface of the work piece without burning through the work piece based on the control information,wherein the controller has a processing power in a range of approximately 10,000 pixels per second to approximately 50,000 pixels per second.

Abstract
A method of scribing a graphic on a material is provided, in which laser output is applied to the material. The laser output is moved relative to the material at a high speed greater than 10 m per second, and at a high power greater than 500 W, to scribe a graphic on a surface of the material. Also provided is a system for scribing a graphic on a material. The method and system of the invention are especially useful in the scribing of building materials.
