Wood products tend to be strong and rigid, this substrate a good choice for post-and-panel
applications. Wood and wood-based products also give signage a rustic look that is popular among clients. However, without pretreatment, woods and medium-density overlay (known as MDO)/medium-density fiberboard (knows as MDF) can absorb water over time, eventually warping the sign. Wood substrates are highly decoratable and can easily be laser- or rotary-engraved and cut, as well as sandcarved or painted. If you’re looking for a less porous substrate with the same natural look, try working with plastic substrates with a wood-grain finish.
