LightScribe is a direct-to-disc labeling tool that uses a special optical CD writer that uses laser to finely etch an inkless design onto the disc's front side, which is coated with a reactive dye that changes color as it absorbs infrared light. The out-of-the-box software HP LightScribe Template Labeler already came with several design templates for ready-to-print labels. The designs appear gray and colorless because the disc usually has a colored front where the laser-etched label appears. Before using the template labeler, the application needs LightScribe System Software (LSS) installed first so it runs smoothly. The Extended Label Contrast Utility has been incorporated into LSS for creating hyper-quality designs with high contrast settings. Incidentally, the HP LightScribe Template Labeler only runs on a Windows platform. More design templates and themes are freely available for downloads at the Design Center of the company's website.
