Laser engraving wood

Post by 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!!
