1) One of the three CIE tristimulus values, equal to the luminous reflectance or transmittance; the green primary. 2) Spectral colour matching function of the CIE Standard Observer used for calculating Y tristimulus,

A subtractive primary colour for colour printing and printing. In additive systems, it is made up of equal parts of red and green light.

The development of a yellow colour on ageing; most noticeable in dried films of white inks or clear varnishes. A printed defect that occurs when ink dries prematurely in the printing areas of the etching. The formation of a powdery coating on the surface of an ink film, caused by disintegration of the binding medium, due to disruptive factors during weathering. The thickness, either real or apparent, of a dry ink or varnish film.

1) One of the three CIE tristimulus values; the blue primary. 2) Spectral colour matching function of the CIE Standard Observer used for calculating the Z tristimulus value. 3) One of the CIE chromaticity co-ordinates.
