Custom signs are simply signs but have been customized to suit your individual needs. They can be to show direction, some danger ahead or anything else.
Customized signs are created and selected with a specific purpose. When you have something that you need people to know specifically, you choose a sign for it.
For a custom sign to be effective, you have come up with a message that is clear and on-point. And this is the whole purpose of having custom signs, as they are clear and to the point. If the message intended is not clear, then it loses the whole meaning.
One great thing about custom signs is that you can make it yourself, as long as you have all the materials. Alternatively, you can hire designers such as the
GS-JJ that have specialized in custom signs, and you will get a quality sign for your purpose.
