Engraved and raised text signs are available for a variety of uses.  Rotary engraving is available using a wide variety of plastic laminates and is also used for brass panels with a black painted infill.  Raised text panels can also be used for braille signage.

Laser engraving creates a chemical bond between the ink and the surface just as permanent as rotary engraving but retaining a sheer surface.  Applications range from brass and stainless steel to plastics and even glass.

Slate signs are a beautiful way to create unique signage.  Natural slate with smooth, but not highly polished surface can have text and logos blasted into or away from the surface.  The markings and grain of this lovely material weather naturally over time.
