Prepare your vector artwork for laser engraving - you can use this as an opportunity to mock up the final look of the sign by playing with fill colours and superimposing onto a textured background, as I did here. I was using 18mm spruce ply which was to hand.
If you would like to colour the background of the image, now is the time to do that. In this example we were going for a bare timber background.
In areas of the artwork where two different colours border each other (eg. in the 'V' of 'Tchai Ovna' in the picture), remember to design in a thin raised 'wall' of unengraved area, to mark the boundary for painting later.
Step 1: Laser Engraving
Step 2: Painting
Step 3: Sanding Back
If you accidentally sand away any areas of paint, simply touch them up again as required.
