How important is 'inking' in the American comic style, and what techniques are used?

'Inking' is arguably *the* defining element of the classic American comic style. It provides clarity, weight, and visual impact. Techniques include varying line weight (thicker lines for outlines, thinner for details), cross-hatching for shading, and using different pen nibs for varied textures. A confident, clean line is highly valued. Digital inking emulates these techniques.
