This material is more expensive, no doubt about it. BUT, we see so much defaced signage needing to be replaced it's often quite worth the extra cost. Plus, there are color choices. We engrave from behind which leaves the graphic/text clear. If the sign is going against a colored wall, no paint fill is needed. The pieces in the photo have a variety of clear and color. The cost to paint-fill is $10/color.
In my opinion, ALL signage in public places should be reverse engraved - it will last far longer, needs just a swipe to clean, and has a very professional crisp look.
