1. The document describes a color matching cabinet used to evaluate color under different light sources and ensure accurate color matching. 2. It contains 6 standard lights including daylight, tungsten, fluorescent, and ultraviolet lights. Samples are viewed under each light to detect any differences caused by the phenomenon of metamerism. 3. The cabinet adheres to international standards for color assessment and is suitable for industries involving fabric dyeing, garment manufacturing, and other color-critical applications.

12. Color Matching Cabinet Confirms with following international
standards:
1. ISO 3664,
2. BS 950,
3. ASTM D 1729,
4. DIN 6173

13. 1. The equipment offers a wide viewing area equipped with multiple light
sources or lamps to detect the phenomenon of Metamerism, where
samples appear to match under one light source but is distinctly different
under another. In order to reach the final approval the fabric has to go
through various light sources which include: artificial daylight, cool white
light, tungsten filament light, ultra violet black light, triphosphor
fluorescent light.
2. The sample to be tested and the original sample are to be kept in the
viewing cavity.
3. After switching on the D-65 Light closely check the original specimen and
the specimen to be tested.

14. • When the match is satisfactory, the specimen is to be tested under CWF
Light and TFL Lamps.
• Now the test is carried out under U.V.B Light, it is necessary to ascertain if
both samples react equally to Ultra Violet radiation.
• Then the final test is carried out under TL-84 Philips Triphosphor
Fluorescent lamp tube light is carried to ascertain if the colors are
acceptable at the ‘Point of Sale’.
• All these help in judging the color differences accurately, by comparing the
samples in different conditions. When the match of both samples holds
well under all the lights, it means that the Dyeing, Printing and the
coloring of the fabric or yarn is as per the requirement

15. Color matching booths and visual color
matching
• The nature and intensity of the light source.
• The angle of illumination and viewing the
samples.
• The color of the surrounds and the sample back
ground.
• The size and distance apart of the samples.
• The state of adaptation of the observer.
• The observer’s color vision characteristics.
• An agreement on the color-difference term to be
used.

16. Matching booth design
• The lamps are placed in a recess directly above the
matching surface, preferably behind a frosted glass
cover and/or filter glass which provides reasonably
diffuse illuminant.
• The matching surface and the interior of the
matching booth should be painted a light grey (about
30% reflectance).
• The booth placed at height such that the viewing
angle for the observer of average stature is
approximately 45o.

17. Rules of visual examination.
• Place the specimens in immediate juxtaposition and
should be interchanged to avoid any bias in viewing
them.
• Keep intensity of illuminant high.
• Have the background similar to the specimens.
• Have the illumination spectrally representative of
that normally employed in critical commercial
studies, usually actual or artificial day light.
