Which statement about hard and soft brushes and spacing is true?

• A. Hard brush has sharp edges; soft brush has smooth edges; spacing does not affect stamping
• B. Soft brush has sharp edges; hard brush has feathered edges; spacing controls brush angle
• C. Spacing does not affect stamping
• D. Hard brush has sharp edges; soft brush has feathered edges; spacing controls the distance between brush impressions; lower spacing yields smoother lines, higher spacing creates a dotted stroke

Answer: (D)

The main idea here is how brush hardness and spacing shape the look of a stroke. A hard brush produces sharp, crisp edges, while a soft brush creates feathered, gradual edges because the brush tip falloff is gentler. Spacing controls the distance between each imprint of the brush along a stroke: when spacing is low, the stamps overlap to form a smooth, continuous line; when spacing is high, the stamps are farther apart, resulting in a dotted or segmented stroke. This is why the statement that describes hard edges for a hard brush, feathered edges for a soft brush, and spacing determining the distance between impressions—yielding a smooth line at low spacing and a dotted line at high spacing—is correct. The other ideas conflict with how edge definition and stamping actually work.
