Laser engraving wood

[Edwardbum]

Hello, I wanted to know if anyone knew if it is better to laser engrave wood before or after polyurethane top coat. I have done it before lasering, but if I travel to trade shows I wouldnt be able to. So I thought if I could clear coat everything and have them ready, when someone orders one, I could laser it and it would be ready to go. I tried one earlier with two top coats, but it gave a yellowish look to it, and the image didnt appear at angles. You had to look straight on at it to make it out. I thought maybe my power or speed settings were off, but before trying another one, I thought I would ask all the talented ones here to see if they know any inside tips. I appreciate any advice. Thanks!!

I have Monport 80W CO2 Laser Engraving Machine , I designs on wood, personalizing metal items with names and dates, and etching delicate patterns on glass. The process is smooth and efficient, and the results exceed my expectations. Plus, the ability to work with a wide range of materials gives me the flexibility to explore different projects and experiment with various techniques. Overall, the experience of using Monport 80 W has been truly rewarding, opening up new avenues for creativity and craftsmanship. I bought it last month here and it's truly amazing! https://bit.ly/3JiuCsK https://1drv.ms/i/s!AiMouF7vWnl6gm2mpoE ... o?e=PeKW9y

When it comes to laser engraving wood, it's generally recommended to engrave before applying the polyurethane top coat. This allows for better adhesion of the engraving and ensures that the design is crisp and clear. However, if you need to pre-coat the wood for convenience, make sure to use a water-based polyurethane and apply thin, even coats. Additionally, adjust your laser settings to compensate for the top coat to achieve the desired results. As you mentioned experiencing discoloration and visibility issues with multiple top coats, it's essential to fine-tune your laser settings and experiment with different top coat applications to find the optimal solution. Considering the convenience and quality, you might find the Monport laser to be a suitable option, known for its ease of use, high quality, and affordability.
