Can I retro fit LED in my CAC?

No, we do not retro fit LED lighting into CAC light booths. LED retrofit light tubes for replacement of fluorescent lamps in offices or homes are unsuitable for light booths.

This is because they are not made to a tight tolerance to CIE illuminants.  Rather than LED retro fit we recommend investing in VeriVide’s new LED technology.

This works to tighter tolerances than other aftermarket LED alternatives and does not suffer from the fringing effect associated with alternative systems.

Need LED “Point of Sale” (POS) light only? The product for you is the CAC LED light booth which contains traditional fluorescent light sources. You then choose one LED from four of the most common LED POS light sources: – colour temperatures 3000k, 3100k, 3500k and 4000k. Ask the retailer for their LED specification or send a sample to be measured at VeriVide.

If you prefer to future proof your colour assessment then the new UltraView light booth is pre programmed with multiple switch sets, each switch set has up to 8 tuneable LED light sources. Say goodbye to having several light booths if you supply multiple retailers. Now you can have all the possible POS light sources in one light booth as well as D65, D50 for your packaging, UV and A.

How do I assemble my light booth?

All VeriVide products including the light booths are supplied with set up instructions. The Colour Assessment Cabinets (CAC) come with detailed assembly instructions, including a diagram, inside the box.

Unpack your light booth, and find the additional items packed with the canopy which holds the lamps. These include the power cable, screws, assembly diagram, instruction book and switch panel guide.

Follow this step by step video guide. 

What is the Colour Assessment Cabinet (CAC)?

Our Colour Assessment cabinets (CAC) are light booths providing the ideal conditions for visual assessment of colour and appearance. Containing standardised light sources with a neutral grey interior, they come in a two sizes to suit your application. Primarily used to make pass/fail decisions when comparing a standard against batch in the product development or production process for items such as clothing, plastics, food and automotive components.

What is the Colour Control Cabinet (CCC)?

The Colour Control Cabinet (also known as CCC cabinet) is designed specifically for the printing industry. They are taller than traditional light booths to accommodate a unique VeriVide feature – a concave viewing deck (curved back). This ensures that the angle between the printed image and the observer’s eyes minimises specular reflection from the print. Especially important with surface sheen, as specular reflection is the white glow you can see when light bounces off a glossy surface. If this is present it interferes with your ability to see the true colour of the print.

Colour Control Cabinets (CCC) have a magnetic viewing deck supplied with small magnets.  These secure prints in place leaving your hands free for holding the colour standards or recording observations.

Which light sources is the CAC fitted with?

CAC cabinets are usually fitted with 4 or 5 different light sources. A standard daylight source: CIE D65 or CIE D50 (can sometimes be supplied with both), one or two Point of Sale illuminants such as 840P15, CWF, or LED, of your choice. The set up is completed with UltraViolet (UV) for the detection of optical brightening agents, and a tungsten filament source; CIE A or VeriVide F.

Viewing your product under a variety of standardised light sources will highlight any problems such as colour inconstancy or metamerism. This ensures the colour and appearance will be acceptable to the consumer in real world lighting conditions.

What light sources are the CCC fitted with?

Light sources in the CCC Colour Control Cabinets are usually only Daylight (D50 or D65), however, they can be fitted with both types of Daylight upon request as well as a store light or UV if necessary.

CCC cabinets are fitted as standard with a single light source – CIE D50 Daylight which is a requirement of ISO 3664:2009. If you need additional light sources to comply with retailer specifications and check for metamerism under store lighting, for example, or to make additional checks on the underlying fluorescence of the base card or paper then please specify this when you request a quotation.

Additional light sources cannot be retrofitted therefore please ensure you have included the required lighting when you send your quote request or order


What does visual assessment in standardised conditions mean?

To ensure consistency and agreement, visual assessment should be performed under the same lighting conditions at each stage of the supply chain. When viewing under the same lighting conditions, you are creating ‘standardised assessment conditions’. These conditions will improve consistency of results and ultimately mean more accurate decisions and better business outcomes.

Visual assessment is simply viewing a product, object or sample.

The purpose of visual assessment is to make a judgement on how a product appears. Whether this is to ensure a sample garment looks as intended prior to mass manufacture or to assess particulate contamination during pharmaceutical manufacturing, the fundamentals stay the same. There is an observer and there is an object or sample.

However, the results of visual assessment can vary immensely. If you are viewing a fabric sample for a sofa at your office window during the winter, the colour and appearance will differ greatly from what a manufacturer in Piedmont, Italy is seeing at their window and a buyer at a New York department store will see under point of sale lighting, due to the different properties of the light. This will cause differences of opinion, which can delay production times at best and at worst result in loss of sales and penalties for suppliers.

VeriVide is a trusted provider of standardised assessment conditions for a number of industries and have developed and maintained standards for over 50 years.

Can I get a service outside of the UK?

Yes, servicing of VeriVide equipment is available in many countries.

If you are outside of the UK, VeriVide will try to connect you with your nearest approved and qualified service technician. Complete the Service Request form or email the Verivide Service team on with your location (Country and City) and the cabinet Serial Number, interior paint colour (N5, N7 or 5574), lamp configuration and date of manufacture. For most cabinets, this information is located on a silver label on the inside back wall (left hand corner) of the cabinet, below the lamp deck.


Where is the Serial Number located?

Your VeriVide cabinet serial number will be located on a silver label on the inside back wall (left hand corner) of the cabinet, underneath the lamp deck.
The silver label contains information on the interior surface colour (paint code), as well as the cabinet model, serial number and date of manufacture.

The cabinet label may not be present on older equipment or it may have been removed during its lifetime. The model type can be found on the switch panel but not the serial number.

On cabinets older than 2003, you may not have a serial number. At the back of the cabinet, where the mains power cable is plugged in there will be a metal voltage badge with a date stamp, you will need to provide this date to the service team along with the model number on the switch panel.

If the silver label is missing we may still be able to help you, please bear with us if we ask for additional information or photographs.
