Jun 15, 2022 · Color mapping is a method of assigning different speed and power settings to different parts of an image based on colors. For example, you could make all red pixels engrave at a much higher power than blue pixels, which would make the red areas of your design much more pronounced. This works with both engravings and cuts, so you could have a ... The laser marking process During the annealing process, a color change occurs as a result from the heat that is applied directly to the metal. This means that there is no ablation or material removed from laser processing. Stainless steel, as an example, will change color at around the time that the temperature reaches a range of 200 to 300°CWith CO2 laser marking and new Fiber laser technology, Martian Laser is able to achieve depth, color change, and permanent markings into metals and plastics. Laser Marking into metals with a CO2 Laser achieves a crisp clean marking. The color change of the engraving depends on the type of metal and the type of coating.

The laser sensitive pigments are easy to incorporate into plastic formulations. They are ideal for adding high-contrast, razor-sharp markings – even at high speeds, and even with low-energy lasers. In laser marking, the marking is applied directly onto the surface using an intensive pulsed laser beam. The interaction of the focused beam with the surface leads to a change in the material – for example, discoloration, structuring, engraving or material removal. It is a chemical modification which causes a color change of the material surface. Laser Carbonization can be used to mark organic materials and light plastics, the incident laser beam leads to the rupture of the chemical bonds and the carbon of these bonds is released. In the case of carbonization, the marked material always has a darker color.The same laser can accomplish either technique simply by changing settings within the laser marking software.

Feb 12, 2019 · Color laser marking, or color laser engraving as it’s also known, is the process of adding color to an object that is being marked. “Marking” is the more apt term since engraving removes a portion of the material’s surface, creating a cavity, while marking merely “stains” the surface. During the laser marking process called annealing, no material is taken away, which means there is no ablation. There is no tangible mark on stainless steel and other metals; however, a color change occurs through heating up the metal. Stainless steel, for example, changes color when it reaches temperatures between 392 and 572 degrees.As of this writing, color laser markings for plastics is still limited, but recently developed techniques may soon change that across the industry. At present, plastic materials that are marked remain in the same color "family" as the original material, with variations in light and dark.Manufacturers precipitate a chromium oxide to change the color.
