How to use color-matching cabinet for the textile industry?

Color matching is an important aspect of quality control. This process will ensure accuracy and consistency in the shades of colours across various textile products. By conducting rigorous colour-matching tests, manufacturers can guarantee uniformity in their end products, leaving no room for deviations or inconsistencies that may compromise quality standards. Thus, to make it easy for the manufacturers to conduct a quality test on the materials, we at Presto have designed a high-quality lab testing instrument known as colour matching cabinet.

Working of Presto colour-matching testing equipment

• Place the material at the bottom of a viewing booth at the distance from the illuminator required to obtain the specific luminance. The specimen should be viewed at a distance of 450 to 600mm (18” to 24”).
• When viewing a glossy surface, it is necessary to avoid seeing the light source secularly reflected by the surface. This may be accomplished by illuminating along the normal to the surface and viewing at 45° C to the normal or illuminating at 45°.
• The INCA Light consists of four incandescent bulbs. Assessment should be done under filament lighting to ensure that the two samples are still matching. It is this light under which Metamerism is detected (Metamerism–when samples appear to be the same under one light source and become altogether different in another light). If the match is satisfactory, proceed on to the next light.
• The U.V. Light switch should now be put ON to enable tests to be carried out under ultraviolet light. With the widespread use of fluorescent dyes and brighteners, it is necessary to ascertain if both samples react equally to ultraviolet radiation. It is often found particularly in the case of white samples the U.V.B. Light clearly indicates the presence of fluorescent dyes and bleaches.
• A final test under TL-84 Triphosphor Fluorescent lamp is carried out to ascertain if the colours are acceptable at the ‘Point of Sale’.
• If the matching of both the samples holds well under all the lights. It means that the dyeing, printing, and colouring of the sample are as per the requirement.
