At Seattle Engraving we employ 3 main methods of creating signage.
Rotary Engraving Rotary engravers are computer controlled engraving machines that use a spinning carbide cutter to engrave deeper than other methods and generally provides for a more durable sign or tag. See a video of a rotary engraver here.
Laser Engraving Although laser engraving has its limitations, it provides for a greater number of materials such as plastic, wood, glass, leather, paper, and stainless steel.
Vinyl Lettering and Signs A vinyl cutter is essentially a plotter for cutting vinyl lettering and graphics which can be applied to a variety of substrates including glass, PVC sheets, automobiles, and magnetic materials.
