dot gain

(redirected from Optical dot gain)

dot gain

An increase in size of each dot of ink when printed due to temperature, ink and paper type. A press operator tries to minimize dot gain, which can muddy the printed image.

The deformation of the screen element can be divided into two components mechanical dot gain and the optical dot gain.
Optical dot gain refers to the appearance of a given halftone, to the human eye or densitometer, when viewed at normal viewing conditions.
Even though this model has pure stochastic nature it makes feasible quasi experimental approach in optical dot gain studying.
Optical dot gain is most often a problem when the substrates readily absorb the inks.
The fundamental cause of optical dot gain is the lateral scattering of light within substrate(Calabria, 2000).
This paper shows that the lateral scattering and optical dot gain are affected with medium characteristic absorption and transmission spectra, which depend on the composition of the substrate, which in turn, depends on the proposed application of graphic products.

The mentioned oscillation of the printing quality is mostly seen in the dot gain which is in the researched conditions dependent on the optical dot gain.
Viscosity should not theoretically influence the dot gain but different viscosity does not only change the geometrical dot gain but also the optical dot gain which defines the light passing through the screen element and the reflection in the eye or measuring device.
