Definitions for "Dot gain"
The increase in dot size, or shape, between the film stage and the final printed image. This gain can be considerable, 15% or more, and can drastically change the perceived appearance of the colour being printed.
A phenomenon, which occurs when wet ink comes in contact with paper. As the halftone dots are applied to the paper, the wet ink spreads, causing the dots to increase in size and halftones to appear darker. A number of factors affect dot gain.
A printing problem where dots print larger than desired, creating darker tones or color imbalances.
