Materials and Substrates

A material in sign making refers to the physical surface the ink is applied to. Nearly all materials used in sign making have a specific inkset or laminate to use in order to maximize longevity. Signs for Success always matches materials with the proper inkset and/or laminate for optimal quality and longevity. Materials are matched to the substrate as well, which include a range of longevity from 1 to 10 years. Specialty vinyls and laminates are used for textured surfaces, vehicle graphics, window overlays, and many other applications.

Corrugated Plastic Coro signs are most economical and signs that we can get out fast and inexpensively

Corrugated Plastic / coro

Referred to in the industry as “Corex” or “Coro,” this material is predominately used for temporary and promotional signage.  It’s ideal for lawn signs such as election signs, sales and contractor signs, directional signage, real estate signs, or site signs for new building projects.  Signs for Success is one of the only sign companies in Spokane that uses an opaque coro for our double sided coro signs.  This way the image from the second side does not telegraph through.
