Trang 12Color Matching Cabinet Confirms with following international standards:
Trang 131 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.
How Color Matching Cabinet works?
Trang 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
How Color Matching Cabinet works?
Trang 15Color 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.
Trang 16Matching 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.
Trang 17Rules 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
