Main identification signs introduce and welcome visitors to your facility and should be large, strategically located and easily seen at a distance. They should carry your logo or trademark, your color scheme and are preferably illuminated. Depending on location, main identification signs can be large low-profile signs, pylons or monument signs, and can incorporate LED message units. Secondary site identification signs tend be somewhat smaller and should confirm destinations or aid in establishing recognition of building entrances or various areas of a campus/facility.
