Definition

Sketch line is a line treatment that specifies searching repeated strokes, light underdrawing, and quick varied lines as one image-control axis. It does not determine subject, composition, era, or creator.

In more detail

The image is structured through searching repeated strokes, light underdrawing, and quick varied lines. Adjacent material, medium, process, and finished-appearance elements remain independently combinable, and named works or brands are outside its scope.
