If you are looking for the perfect combination of compliance, aesthetics, and cost-effectiveness in signs, then you should consider plastic engraved signs. These are signs that are made using plastic sheets that are then engraved with the designs that you choose or create. These are also easy to customize to become compliant with ADA rules since these come in many different colors that can meet the contrast percentage required for these signs.
What other ADA rules do signs have to follow and what makes plastic a great material to use to create these features that are needed for compliance? Here are some of the necessary features that ADA signs:
Braille translations – braille dots are added to signs with the use of what is called a rastering technique. In the past, these dots were added with the use of engraving as well, with the dots being marked into the plastic substrate using the same marking method used to create the other characters on the sign. Since the revised ADA guidelines have come out however, with specific instructions that state braille dots need to have a rounded and smooth dome-like top, the rastering method became the norm when it came to adding braille. Engraving became the method used to create the holes needed to hold the beads that are used in these braille translations.
Raised characters – characters on ADA signs that are used to mark doors have to be raised, and for a good reason. This is because these same signs have to be used by people with visual impairments, and the raised characters are there for them to try and discern what is written on the sign with the use of their fingertips. These raised characters are added to these signs even when braille translations are present because not everyone can actually read braille. Some people lose their eyesight at a later age and find it hard to learn braille, which is why these raised characters are very useful for them.
70% Color Contrast – while this color contrast rule has nothing to do with engraving, it is still easy to do with plastic signs since plastic substrates come in many different colors that can be easily matched for proper contrast percentages. These are usually glued together and then engraved to create the raised and recessed parts of the sign in the right color. This color contrast is necessary to make the signs easier to read from any distance.
Aside from these, plastic signs are also lightweight, which gives you a lot of mounting options to choose from. Plastic signs are also cheaper than other signs made using other materials, but are still very durable, which is what makes them cost-effective.
