Why Use Lasers to Engrave Signs?

Modern laser cutters are an ideal solution for the manufacturing of bespoke signage today because they can be set up within very short time frames. Indeed, the idea that laser cutters are only used to shape high-tech components for sectors like the aeronautical industry is quite out of date. They are perfect for not only cutting signs to their desired dimensions in numerous different materials but for engraving them, too. Why is laser engraving such a beneficial production method for today's signage requirements? Read on to find out.

Vandal Resistance

In the modern world, any sign that is erected in the public realm needs to be robust. This is mainly to avoid vandalism or, perhaps more accurately, to better withstand its effects. When a sign is engraved rather than painted with information, it is necessarily more robust because its wording or symbols will be part of the structure of the sign itself. Therefore, it is almost impossible for vandals to prevent the sign from being read and, therefore, understood, even if they were to coat it entirely in spray paint.

Weather Resistance

Another aspect of laser engraving worth considering is that it will be able to withstand even harsh weather conditions. Signs that are exposed to lots of sea spray, for instance, will often look fairly drab after a few years following their installation. However, engraved signs with lettering that stands proud of the main surface of the sign will not suffer from this sort of erosion so long as a corrosion-resistant material is chosen. Equally, laser engraving tends to beat other methods hands down when it comes to solar exposure. Excessive ultraviolet light can fade many types of signs, but it has little effect on those which have been engraved.

Improved Readability

One of the most important aspects of laser-engraved signs is that they can be 'read' by touch. Although this will only help if the sign is placed at a suitable height, wayfinding information, such as maps, can be read by visually impaired people by simply running their fingers over the signage. Equally, the engraving techniques used by modern laser cutters will also mean that wording can be replicated in Braille in a highly accurate fashion, another big plus point. This is crucial when the wording will alter from sign to sign depending on the context of where it is to be installed because the instructions to the laser cutter to alter the Braille content can be automated easily with today's generation of computer-controlled laser engraving systems.
