Prepress & Vector Scribe Notes

1. Single-Stroke vs Closed Geometry: Drag engraving does not mill pockets with an endmill; it displaces metal under spring pressure without spindle rotation. Low-res bitmap artwork converted with dual outlines causes unwanted double-line cutting. True single-stroke centerline vectorization is mandatory.

2. Hatch Stepover Density: To achieve solid high-contrast filled areas without leaving untouched ridges, stepover $S$ should equal $W \times 0.70$ (30% line overlap).
