Using the newest Laser Engraving technology, the plate is etched a fraction of an inch, which turns the metal a rich brown color. Laser marking is permanent and easily visible.
Text and graphics work best. Photographs will also work, but for best results, photos should have a lot of white areas and should have good contrast. Images are converted to black and white before engraving. Shades of gray are engraved using a subtle pattern of tiny dots.
