I've laser engraved text onto a wooden plaque . The engraving has some finely spaced grooves. I want to apply a stain on it , sand it out so that the engraved portion is darker than the rest. I'm planning on using a fine-grit sandpaper to hand-sand it. I'm a little worried that sanding will blend the engraved and non-engraved portions of the wood - the engraving is probably 1mm deep.
Is there an alternative ?
