On the other hand, modern manufacturing methods mean that more colours do not always equal higher costs. The James Gray Group has equipment which makes it possible to have full colour photographs or emblems on a sign. See the Sign Directory entry for full colour computer generated PVC graphics for more details on this. Lighting is another tool which you can use. It not only makes your sign visible in the dark, but can create attractive effects like shadows.
Box signs are available internally illuminated.
Other signs can be illuminated externally with trough and flood lighting, both reasonably inexpensive. A good example of a special lighting effect are laser cut perspex letters with coloured faces set into a dark background and backlit. The light coming througn the edge of the letters creates a stunning halo effect. Choice of materials and methods are important factors when designing a sign. Here you will be in the hands of the sign company.
