but with a laser you will have blackened edges and engraving. It contrasts well, but if you don't want the black, don't go with the laser.
The blackened edges and field are to be expected. There is also deposition of combustion products onto surrounding areas. My source informed me to apply the chosen finish onto the woodwork first, thus sealing it and preventing the smoke and ash from entering the pores. The residue wipes off of the surface of sealed wood.

I used the services of a graphic arts designer to obtain the files needed to guide the machine work.

Of course. The deposits just wipe off or might need a light sanding. I was refering to the burned edges of a cutout or field. If what you want is merely a relief without contrast, a laser isn't appropriate. I don't finish first for a few reasons - most finishes are flamable and/or toxic when burned and even though the lasers are vented and cut plastic all the time, I don't necesisarily like to add more toxins to the environment if I can. Also, it will need to be refinished anyway to cover the burned part, so why do it twice? Maybe use sanding sealer for the pores, but no need for a full finish.
