Light from the Xenon lamp has the nearest artificial wavelength distribution to that of the sun. Generally the time the ink takes to fade depends where in the world you are. Each textile fade card features pieces of wool cloth dyed with blue dyes of different degrees of fastness which are used as light fastness standards. The Blue Wool standard relates to our star icons as follows: Traditionally this test was developed for the textiles industry but it has now been adopted by the printing industry as a measure of "lightfastness" of ink colourants and also within the polymer industry for measurement of pigment & colour stability (lightfastness). The blue wool card allows you to monitor the net exposure to light given to objects on display and to alert conservators to adjust intensity of illumination.

The European version is part of the ISO standards, and it gets its name from the dyed blue wool fabric bands or swatches that are used to visually compare fading rates. JMB cadmium pigments, like all cadmium pigments, have excellent light-fastness throughout the whole range from yellow to deep maroon. These are a series of 8 wool fabrics dyed with specified blue dyes to give blue wool cloths ranging from very low light fastness to very high light fastness. Moderate resistance. £0.00, Mannequins for Conservation Storage & Display, Photo Album Refill Pages - Print File Archival Storage, Unbuffered Large Textile Storage Boxes | 5 Sizes | Up to 1524mm x 457mm, Unbuffered Acid-Free Tissue Paper - 16gsm, Light Meter with Thermal Radiation Sensor (Lux/UV/Temp/Infrared), Environmental Meter | RH / Temp / Light (UV & Lux). The scale consists of 8 different strips of wool, each dyed with a blue dye of differing lightfastness. Very Low resistance. Each textile fade card features pieces of wool cloth dyed with blue dyes of different degrees of fastness which are used as light fastness standards. The Blue Wool Scale measures and calibrates the permanence of colouring dyes. The “Blue Wool Scale” is the internationally recognized method of quantifying lightfastness, defined under the British Standard BS1006. A dull climate will be very different to a desert exposure in Africa. The scale consists of 8 different strips of wool, each dyed with a blue dye of differing lightfastness.

Traditionally this test was developed for the textile industry, but it was later adopted by the printing industry as a measure of lightfastness for ink colourants. The Blue Wool test standard is comparable to ASTM D 5383-02 and ASTM D5383-97. Testing is typically done by controlled exposure to sunlight, or to artificial light generated by a xenon arc lamp. The “Blue Wool Scale” is the internationally recognized method of quantifying lightfastness, defined under the British Standard BS1006. Blue Wool 2 –About twice as good as 1. Textile fading cards test for effects of light on paintings, documents and textiles with blue indicating scales. 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. "The Blue Wool Scale measures and calibrates the permanence/lightfastness of dyes and pigments Two identical dye/pigment samples are coated out then one is placed in the dark as the control and the other is placed in the equivalent of sunlight for 3 months. This forms a numerical scale of 1 to 8 where 1 has the poorest light fastness, to 8 which has the best light fastness. Vinces Road The light-fastness is indicated on each as follows: *** = Maximum light-fastness = 7,8 Blue Wool Scale ** = Very good light-fastness = 5, 6 Blue Wool Scale * = Good light-fastness = 3, 4 Blue Wool Scale Each textile fade card features pieces of wool cloth dyed with blue dyes of different degrees of fastness which are used as light fastness standards. Blue Wool Scale "The Blue Wool Scale measures and calibrates the permanence/lightfastness of dyes and pigments. The Blue Wool Scale measures and calibrates the permanence of colouring dyes. Blue Wool 5 –Up to 6 months.
