A classic example is the automobile industry: the colorants used for interior fabrics, plastics and paints may be chosen to provide a good color match under a cool white fluorescent source, but the matches can disappear under different light sources (e.g. daylight or tungsten source). Furthermore, because of the differences in colorants ...
A colorimeter or a digital camera with a color filter array can, under certain conditions, be used as an alternative to a spectrophotometer. [7] [8] The illuminant and observer conditions should be specified when citing a measurement (e.g. D65/10°). [9] The quality of a colorimeter may be assessed using the means in CIE publication 179:2007. [10]
Thompson worked to simplify Holmgren's method so that a "non-professional" test could be performed and the results can be forwarded to an expert for interpretation. [2] Thompson reduced the number of matching colors and numbered each one. [2] This test is one of the earliest examples of a psychological test used on a large group of people. [2]
Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
Table-top spectrophotometer Beckman IR-1 Spectrophotometer, c. 1941 Beckman Model DB Spectrophotometer (a double beam model), 1960 Hand-held spectrophotometer used in graphic industry [1] Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a ...
Traditionally this test was developed for the textiles industry but it has now been adopted by the printing industry as measure of lightfastness of ink colourants. [ 1 ] [ 2 ] The American Association of Textile Chemists and Colorists pioneered the work on these test methods and together with the ASTM D13 committee.
