There are three main technologies to consider: 3D Laser Subsurface Engraving, which creates an image inside the crystal without damaging the surface; Sandblasting (Etching), which provides a classic, frosted tactile feel on the surface; and UV Color Printing, used for vibrant, multi-color logos. For high-end corporate gifts, 3D laser engraving is preferred as it never fades and provides a sophisticated, 'floating' effect. Always request a digital mockup or a physical pre-production sample to verify font legibility and logo alignment.
