The drawing cutting off the black spray paint,
at full power on the laser cutter
(in about 20 minutes)
After the laser cutting
This is not unlike making a circuit board.
Note: that after the high resolution drawing (181) was downloaded, it was "flipped" horizontally with XnView (or any other digital program), before being sent to the laser cutter. That is because when the plate is etched and inked, it will print a reverse image on paper.
By flipping it first digitally, we will be able to print the image in the same orientation as it is in my book. If we were etching and printing words, they would come out backwards in the final print, if we did not "flip" them horizontally first.

The proof print
on the press bed
The proof print is somewhat unexpected. I did not take off the spray paint ground before printing, which probably accounts for the grey plate tone. The spray painted surface has a matte texture, that did not wipe off well with the tarlatan wiping rag.
The actual lines of the figure however, were much lighter than I anticipated. Perhaps the lines are too thick, and therefore did not hold the ink tightly, when the plate was wiped with the tarlatan rag.
