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. ## Claims ### Claim 1 A method of laser scribing a graphic onto a workpiece, comprising: applying control information from a controller operable at a controller speed in a range of 10,000 pixels per second to 50,000 pixels per second to a laser operated to produce a laser beam, and laser scribing a graphic onto a surface of a workpiece with the laser beam based on the control information, said laser scribing comprises moving the laser beam at a relative scan speed in a range of 10 m/s to 50 m/s and lasing the surface of the workpiece without burning through the workpiece, wherein the laser is operable to produce the laser beam with a power output in a range of 500 W to 5000 W. ### Claim 2 (depends on 1) The method of claim 1, wherein the laser is operable to produce the laser beam with the power output in a range of greater than 500 W to 5000 W. ### Claim 3 (depends on 1) The method of claim 1, wherein the controller speed is operable in a range of 20,000 pixels per second to 50,000 pixels per second. ### Claim 4 (depends on 1) The method of claim 1, wherein the relative scan speed is in a range of 30-50 m/s, and wherein the laser is operable to produce the laser beam with the power output greater than 1000 W. ### Claim 5 (depends on 1) The method of claim 1, wherein said laser scribing further comprises applying the laser beam to the workpiece over a scan length of at least 0.9 m. ### Claim 6 (depends on 1) The method of claim 1, wherein the controller is operable to change the power output every 1 to 4 pixels. ### Claim 7 (depends on 1) The method of claim 1, wherein the workpiece is denim. ### Claim 8 (depends on 1) The method of claim 1, wherein the workpiece is leather. ### Claim 9 A method of imparting a visually perceptible change to a workpiece, comprising: providing a laser and an operably associated controller operable to change the power output every 1 to 4 pixels; providing a workpiece; providing a controller operable at a controller speed in a range of 10,000 pixels per second to 50,000 pixels per second; selecting denim as the workpiece; applying control information from the controller to the laser to produce a laser beam having a power output; and laser scribing a graphic onto the workpiece using the laser beam of the laser based on the control information. ### Claim 10 (depends on 9) The method of claim 9, wherein the graphic has a resolution of 32 to 60 laser lines per inch. ### Claim 11 A method of imparting a visually perceptible change to a workpiece, comprising: providing a laser and an operably associated controller operable at a controller speed in a range of 10,000 pixels per second to 50,000 pixels per second; providing a workpiece; applying control information from the controller to the laser to produce a laser beam having a power output; and laser scribing a graphic onto the workpiece using the laser beam of the laser based on the control information. ### Claim 12 (depends on 11) The method of claim 11, further comprising the step of selecting denim as the workpiece.
