Step 18: Inking the engraving
The laser cut parts will come with a paper backing on them. It is a good idea to leave it on to keep the back as clean as possible.
Cover the laser cut part in ink. Use circular brush strokes to work it into the engraving.
Using the rag, wipe of the excess. Some ink should stay in the engraving and the rest should wipe off easily. Sometimes it may take a few goes to work the ink in to a suitable level.
