What is a Channel Letter Sign and How Is It Used for Business Storefronts?
A channel letter sign is a three-dimensional graphic element—typically an individual letter or logo—constructed from metal and acrylic, illuminated for high visibility and commonly mounted on the exterior of business storefronts. These signs are designed to attract attention, reinforce brand identity, and enhance visibility, especially at night or in low-light conditions.
