Laser engraving is a highly versatile process in the signage or product labelling industries. It usually involves using computer-controlled machines and lasers to create a variety of signs on almost all kinds of materials. What's more, it comes with many advantages. It's a non-contact, high-speed, low-cost and environmentally safe process that results in highly durable and clear markings or labels. However, precision is the key to all these. And if you are new to laser engraving, you are likely to make a few costly mistakes.
