Outdoor signs - laid flat. Which material?

Hello All, I'm new here but certainly hope to get involved.

Back in 1989 when I was a draftsman I used an early Roland Camm-1 but then my work took a completely different path. Things have moved a long way in the interim.

Anyway, I have been asked to supply some signs (actually a few 100) along an outdoor route. They are to be 200mm x 100mm x 3mm, with simple lettering.
It would seem that the choice would be Dibond ACM, with the top layer engraved to show black lettering, or similarly a two tone plastic.

The concern I have, is that the signs are to be laid flat, and so the grooves for the lettering will fill with rainwater and as such might be more exposed to the weather than signs mounted vertically. Over a period of years this might result in early de-laminating.

I wonder what your thoughts might be. And which choice of material.

Hi, welcome to the mad house. I'd use cut vinyl with a solvent based adhesive for the job. These materials are suitable for boats etc so should have no problem doing what you're asking.

The signs are to be rigid and screwed (stainless steel screws) to wood sleepers.

Hi Barlow. I would be inclined to reverse print a good quality polymeric vinyl as David suggested, & apply to a clear polycarbonate panel, should be pretty bulletproof.

Re: Outdoor signs - laid flat. Which material?

The client is happy for white/black lettering DiBond or plastic (sample is from Trotec), with an initial preference for DiBond, which price wise is probably better. I was probably overthinking the fact that the signs would be laid flat.

The work could be carried out on site and I was thinking about setting up equipment there and looking for a simple but robust machine and software that would do this job.

Any suggestions?
