A brief description of the procedure:
If you want a happy face raised up in the center of an oval on a blade,first draw the oval perimeter with a resist pen (a Sharpie works well).Now black off the entire blade except the oval.Draw the happy face in the oval. The areas that are black will be raised, the unmasked areas will be etched. Etch deeply,neutralize, clean off the resist with acetone and buff the blade.The happy face will be raised up in a recessed (and frosted) oval.
This is also a real good way to mark a damascus blade. Once the blade is finished and ready for the etch,stamp your mark and black out an oval covering the mark. (you can also just write your initials,or draw your logo on with a Sharpie).Etch as normal. The covered area won't etch and will be bright and smooth.It will be slightly raised as well.If you wrote on the blade,the writing will be raised and shiny.
