A Guide To Understanding Graphic Arts Densitometry

Source: X-Rite, Inc.

The Equation: Density = log10 1/T

Where T = Transmittance
Transmission density is a function of the amount of light which passes through the film.

Black and white transmission densitometers are used for film inspection, as well as scanner and imagesetter calibration and linearization. The basic measurements are Density and Dot Area.
