What is with this sign?

[Jean Shimp]

A local apartment complex called us about replacing their pool rules sign. The photo shows the condition of their current sign. The letters are raised. I'm not sure what material the sign is made out of. On first glance it looked like CNC routed HDU. But looking closely you can see that the letters are too sharp for a router bit to have cut them. I am thinking this sign was done by a laser? What is happening to the letters? They have chunks falling off. It doesn't look like birds or insect damage.

maybe kids picking at it

They're probably just flat cut PVC letters, companies like Gemini sell them. PVC isn't really the best for outdoor use, and it's probably in the sun all day. They get brittle, anything hits or picks at it and they fall apart.

If they want the same style, go with the flat cut metal letters, a bit more, but they won't have to keep replacing them.

Possibly used laser cut tactile material?

Thanks for your reply. This is a pool rules sign that is loaded with letters and they are perfectly spaced. It would take a LOT of time to set each letter and I don't see any evidence of adhesive or tape residue where the missing parts are. The sign looks too perfect to be done by manually applying the letters. The size of the sign is 40" wide and 50" tall. The size of the letters are 1" high.

That's what pattern are for

It looks mutoh printed to me, or something similar that has a buildable print fill for tactile. In my experience rowmark doesn’t typically erode like this, but kids and a pool environment could do weird things.

We used to second surface print a lot for things in locations people liked to pick, or around children.

Is there any bevel that would indicate that the material was cut using a very narrow engraving bit? That's what I would have done back in the day...

Finish peeling the "L" off and see if there is adhesive on the back. Let us know what you find out. : )

Looks like ADA or DDA 1/16" material to me, normally has clear 3m tape on the rear side,
can be laser cut or rotary cut, we do both depending on the aplication.
I would suspect somebody has been picking at it. normally some kid waiting for a ride home

If the letters were cut acrylic they might have lasted longer but Outdoors is notoriously bad for composite signs. . How about if the letters were carved INTO a multi layered Acryllic sheet. You know where its white 3/16" acryllic with 1/16" Black melded on each side. So if an router routs out the black, all the letters are white and carved into the sign!

No there is no bevel or indication that this sign was done with a router.

I am not able to visit this sign but I can tell you, based on several photos that the owner sent me, there is no indication of adhesive residue where the letters are missing pieces.

That's interesting. Have you made a sign like this? What type of adhesive do you use to "meld" the two pieces of acrylic together before routing?

If there is no adhesive then it must have been built up UV ink, which would also explain why it failed.

I would just sell them a new sign, and not worry about the whole story about how the old sign was made incorrectly.

Of course not, that's why they're missing. Sell them an acm and vinyl pool rules sign and move on if you can.

Guess I'm living in the dark ages. I do not know about making signs by using built up UV ink. What type of equipment does this type of fabrication? I would like to know more about this and what type of materials are used.

with some UV flatbed printers, you can print in multiple layers. The UV ink is thick, and as it layers up it gets thicker. I don't know if all printers can do this - ours can (Agfa Annapurna) but I've never had the need to try it. We do 5-layer printing for 2-sided window graphics, and that get's pretty thick, but I've never explored the capabilities of printing braille or something thick.
As others have said, I would sell them some new signs produced within your capabilities. And fitting for a pool environment.
