20140248506 | Graphic Formation via Material Ablation - Techniques for graphic formation via material ablation described. In at least some implementations, a graphic is applied to a surface of an object by ablating layers of the object to form an ablation trench in the shape of the graphic. In at least some embodiments, an object can include a surface layer and multiple sublayers of materials. When an ablation trench is generated in the object, the ablation trench can penetrate a surface layer of the object and into an intermediate layer. In at least some implementations, height variations in an object surface caused by an ablation trench can cause variations in light reflection properties such that a graphic applied via the ablation trench appears at a different color tone than a surrounding surface, even if the ablation trench and the surrounding surface are coated with a same colored coating. | 09-04-2014 |
