Laser method of scribing graphics

Image Number 18 for United States Patent #6685868.

A colored substrate is positioned between a material and a laser, and the material is scribed with a laser that has been directed through the colored substrate. By so doing, color is transferred to the material to form the color graphic without undesirably carbonizing, melting or burning through the material. The energy density per unit time can be defined as continuous power divided by the area of the spot and the speed.
