These patterns are white on a black background to provide the engraver with clear guidelines on how to work.
Tape the pattern behind the glass and engrave the basic outline. Once the outlines have been engraved, remove the pattern and replace it with a piece of black felt for contrast. Filling in and detailing can then be done with the pattern being used as a guide.
