EIA GRAY SCALE
技術(shù)參數(shù)
Data: The EIA grayscale pattern is a standard 2" square projection slide. It
contains two parallel gray scales. The upper scale has nine nominally equal
transmission steps while the lower contains the same number of nominally equal
density steps. The transmission values range from 3% to 60%, corresponding to
density values of 1.52 and 0.22 respectively. The slide is chrome on glass and
densities are achieved by a fine halftone pattern.
