Viewing Booths – essential for print and product Quality Assurance

From photo editing for home use through to commercial colour assessment for print and similarly for product manufacture, controlled lighting is essential.

Demand for tighter quality control, accountability and appreciation of the importance of illumination brings viewing booths to the forefront of essential equipment at all stages of production and presentation for print and product manufacture.


Why use a viewing booth?

The type of light used and its environment determines exactly how we see. In the most basic of terms, with no light there is just darkness, and subsequently the type of light used determines the colour and contrast of what we see.

A viewing booth provides the basis for all forms of visual quality control and decisions on colour.

A viewing booth consists of controlled lighting of a specified temperature (warmth or coolness of the illumination) and intensity, set within a mid-grey neutral environment, ideally shielded from strong external light sources and reflections.

This provides a viewing condition that can be replicated at all times of day and location, as well as optimum illumination for determining colour accuracy and visual quality assessment.

Why are viewing booths available in so many styles and sizes?

Viewing booths are used for many tasks and in many environments, such as comparing; colour in print against a monitor, a proof print against a final print and for quality assessment and presentation of any product. This might not just be ink on paper, but any printed, painted or coated surface, from the colour of your wallpaper or car bodywork through to the clothes you wear and food you eat.

What are the more frequently used illumination types?

D50 (Standard illuminant)

D50 (5,000˚ Kelvin) is specified as industry standard temperature for colour assessment of prints. It replicates daylight conditions, and is the primary light source used in the graphic arts industries.

D50 (Standard illuminant)

D50 (5,000˚ Kelvin) is specified as industry standard temperature for colour assessment of prints. It replicates daylight conditions, and is the primary light source used in the graphic arts industries.

D65

D65 (6,500˚k) is a higher temperature (bluer) daylight frequency used for the colour assessment of products and occasionally for flat print work in the pressroom.

TL84 (CWF in the USA)

TL38 (4,100˚k) is used for many modern store applications because of light efficiency. The appearance of clothing, home furnishings, packaging and labels will be important to test under these conditions prior to display in a store environment.

Similarly, Cool White Florescent (CWF) is store lighting to a temperature of 4,150˚k.

Incandescent A

Incandescent A (2,700˚k) is your standard Home Light bulb. This produces a much warmer, ‘yellowish’ illumination than daylight. The impurities in such lighting can cause distortions in colour appearance*.

UV

Ultraviolet (UV) lighting allows for the presence of UV florescent materials to be detected, and can be used to assess specific dyes, paints or finish effects which are detected under UV conditions.


Why test products under multiple light sources?

The colour of a print or product will look different from one lighting condition to another. From natural daylight to a fluorescent tube or to tungsten, images can look warm, cool, flatter and less vibrant depending on the conditions.

Assessing product under a range of different light sources will highlight inconsistencies that only become apparent under a particular type of illumination*.

*This is an affect known as ‘metamerism’. For example, a pair of matching colours made of different materials can appear to look the same under one lighting condition, but different under another.

Colour Appearance Booths

What type of booth do I need?

Viewing booths are available in a comprehensive range of size, format and illumination configuration, optimised for different usage.

Colour Appearance Booths – Multi light-source

  • Predominantly for product assessment, with a flat base and optional angled stands
  • Configurations of 3 to 5 illumination types (D50, D65, TL84/CWF, Incandescent A, UV)

Large Format – Normally D50 but other tubes and multi light-source available

  • Angled base and back-wall for comparative print assessment – sizes to match press-sheet formats
  • Desktop models or freestanding models with storage cabinet/drawer options
  • Integrated monitors available for soft-proofing

Desktop – Normally D50 but other light-sources available

  • Ideal for studio soft-proofing/editing, available for A3 and A2 format
  • Available with dimmer switches to accommodate an accurate brightness match to a monitors output

Luminaires – Normally D50 but other tubes and multi light-source available

  • Units that hang from the ceiling or affix to a wall
  • Symmetric models for table illumination, Asymmetric models for wall illumination
