Visual assessment of colour in accordance with international norms

In order to reliably assess samples when establishing tolerances, to collaborate or discuss the colour and appearance of products, and to accurately specify and approve colour, it is essential to control for as much of the visual assessment process as possible. A well maintained colour viewing light is an essential requirement, providing a neutral space with a number of commonly used illuminants produced specifically for the task. 

Viewing cabinets simplify not only the control of the lighting, but facilitate the exclusion of ambient light, positioning and angling of samples and following other best practice visual assessment guidelines.

According to industry norms for visual colour evaluation, the colour samples should look identical when viewed under illuminant D65 and at least one other illuminant is used to check for metamerism.

The cabinets are suitable for all industries and applications where there is a need to maintain colour consistency and product quality such as Textiles, Automotive, Ceramics, Cosmetics, Dyeing, Food, Footwear, Inks, Packaging and Printing.

In order to view your samples objectively without the influence of surround or background colours, the interiors of the cabinets are finished in a neutral matt grey.

The use of a colour assessment cabinet in quality control is strongly recommend to assure a visual match even when using digital colour data and a colour measuring instrument. The eventual goal of all colour control is pleasing the eye of the customer.
Using the DLS v8 the operator can use the built in display and control panel to easily switch between the pre-set illuminants to assess under standardised daylight illuminants or standardised LED illuminants. The control panel also enables dimming of the light level and the programming and selection of automated sequences of the stored Illuminants to simplify routine working.

JUST Normlicht's patented technology provides an LED light source that fulfils the strict requirements for colour assessment of all industries were colour is crucial. Using a patented multilevel calibration procedure for the LEDs used in its arrays Just Normlicht calibrates each single LED and stores the spectral properties to the unit’s electronic controls.
The patented LED calibration technology ensures accurate spectra for the illuminants in the cabinet over the life of the instrument. The LED array has an expected lifespan ten times that of tube or halogen based assessment cabinets, also greatly reducing the environmental and financial cost of replacement bulbs/tubes each year. 
The LED array utilises a prismatic diffusor to ensure an even light distribution, minimising harsh shadows or reflections, ideal for best practice visual assessment.

The cabinet interior is coated in neutral grey to allow the operator to rest their eyes in between assessments and minimise the risk of any reflections influencing colour perception. The matt coating used within the cabinet can be cleaned from dirt, dust or other light marking. 
An optional angular viewing stand can be used with the cabinet so that assessments can be performed, according to best practice, in a controlled and consistent manner.
The proper use of JUST Normlicht colour assessment cabinets helps to identify and correct product quality and supply chain problems caused by colour inaccuracy. Facilitating collaborating and discussing colour and appearance under controlled lighting conditions.
Several versions of the cabinet are available according to the size of your samples and requirements.

JUST Normlicht LED Technology

JUST Normlicht offers customers the technology of tomorrow by using LED lighting for colour evaluation. Providing enhanced control of the illumination and previously unatainable customisation of light sources.

To control the LED properties to the multiple requirements of JUST Normlicht, a patented multilevel calibration procedure was developed that calibrates each single LED light source and stores the spectral properties in the unit’s electronic controls. 

The multilevel calibration is divided into the basic factory calibration and permanent online-calibration during operation without requiring an additional external metrological device.

The JUST LED technology not only exceeds the conventional standardized lighting technology in light quality, but is now for the first time able to replicate a tremendous colour space with the highest quality. The LED array can achieve a CRI between 90 and 100 and a Metamerism Index < 1.

The multispectral LED lightsource can achieve a colour gamut larger than sRGB and is now able to replicate not only standardized light sources like D50 or D65 for the graphic arts industry but also other light sources like A, C, D55, D75 and any other white or coloured light.

To avoid metameric failure caused by optical brightening agents, the UV-content in the light source is also included.

A second advantage of the JUST LED technology is a lifetime of at least 10 times longer than that of traditional fluorescent lamps. This means not only a stable quality of light over a very long time but also significant savings on replacement lamps over the life of a JUST LED Viewing Booth.

By not using mercury and minimal phosphors (which are both major components of traditional fluorescent lamps) the LED Technology used by JUST Normlicht reduces the amount of hazardous waste being disposed of in landfills across the globe.
