Photopolymer signs are made by a solid one piece construction technique that is requested due to its durability and tamper proof nature.
Interior Photopolymer Signs are truly a one piece construction. They can easily be identified by ensuring that the raised lettering is physically attached (not laminated) to the face plate. The edges of the raised lettering will be the same color as the face plate, and only the face of the raised lettering will be a separate color.
The Photopolymer process utilizes a polymer material that is light sensitive. It is supplied as a clear blank slate. Negatives are printed off with the lettering, pictograms and Braille left clear. The material is exposed with the negatives on top, curing the clear areas of the raised graphics. It then goes through a cleaning process, which washes away all non exposed areas, leaving the text, Braille, and pictograms raised. After being cleansed, the entire sign is exposed again, curing the entire sign. It is then painted, surface (with the edges painted, but the face more susceptible to scratches), or subsurface (edges not painted, but paint more protected). After being painted, it goes through a screen printing process called “tipping” where just the tips of the raised areas are “tipped” a separate color. Finally, the sign is often satin clear coated, ensuring that the screened area has a non-glare finish, as well as providing an extra layer of protection to the sign and paint.
Photopolymer signs are very durable with even the Braille being a physical part of the face plate. They are great for school systems, jails, and any other area they may be subject to tampering. If you’re looking for durability, this is your best choice.
The photopolymer process is a lengthy process, which makes these signs both difficult to produce in a limited time frame, as well as making them a more costly interior solution.
