What is dot gain and its impact on print output?

• A. Dot gain is a decrease in ink spread that sharpens edges.
• B. Dot gain describes the speed of ink drying.
• C. Dot gain refers to misregistration of colors.
• D. Dot gain is the increase in dot size during printing, which can deepen colors and affect sharpness.

Answer: (D)

Dot gain is the increase in dot size during printing, which can deepen colors and affect sharpness. As ink is laid down on paper, capillary action and ink transfer cause halftone dots to spread beyond their intended boundaries. This extra spread raises the ink coverage in that area, making tones darker and edges softer than planned. The result is a print that can look bolder or muddier than the digital file, with reduced detail in midtones and shadows. Other options describe different issues—decreasing ink spread would sharpen edges, drying speed is about how fast ink dries, and misregistration is about color alignment, not dot size. In practice, printers compensate for dot gain through prepress adjustments and color profiling to preserve the intended appearance.
