Printing & reproduction

Halftone dots print larger than intended

Dot gain, also called tonal value increase, is the degree to which a halftone dot prints larger than its intended size, darkening midtones and reducing contrast as ink spreads mechanically on the paper and as light scatters within the stock (optical dot gain). It must be predicted and compensated in the separations so that the printed tones match the intended image. Kipphan's Handbook of print media treats dot gain and its compensation within halftone reproduction. The referent is a tonal-reproduction characteristic of a printing condition, quantified as the difference between the intended and measured tonal value at a given input.[1]

Unit
The percentage increase of a halftone tone from file value to printed value
Recovery means
Not applicable
Measured by
Measured from printed control patches with a densitometer as tonal value increase at nominal dot percentages, and compensated with transfer curves
