Gray Scale

Gray Scale
The Gray Scale is a visual tool used in the textile and dyeing industry to evaluate and grade the color change or staining of a fabric after testing (e.g., washing, rubbing, and light exposure). It helps assess how much a fabric’s color has altered or transferred during durability or fastness tests.
Types of Gray Scale:
- Gray Scale for Color Change – Compares the original and tested sample to measure color fading or alteration.
- Gray Scale for Staining – Compares a white adjacent fabric (before and after testing) to assess color transfer or staining.
Rating System :
– Uses a 1 to 5 scale:
– Grade 5: No change or staining (excellent)
– Grade 1: Severe change or heavy staining (poor)
Intermediate grades (like 4–5, 3–4, etc.) are also used for finer evaluation.
Construction :- Each scale includes pairs of gray chips with varying contrast levels to visually match the test results.

Fabric Moisture Permeability Tester
Fabric Moisture Permeability Tester
A Fabric Moisture Permeability Tester, also known as a Water Vapor Permeability Tester, is a laboratory instrument designed to measure the rate at which water vapor passes through textile materials. This measurement is crucial for assessing the breathability and comfort of fabrics, especially those used in active wear, outdoor gear, medical textiles, and protective clothing. Purpose of Fabric Moisture Permeability Tester The primary function of this tester is to evaluate a fabric's ability to allow moisture vapor to pass through it, which directly impacts the wearer's comfort by facilitating sweat evaporation and thermal regulation. High moisture permeability indicates better breathability, making the fabric suitable for applications where moisture management is essential. Working Principle of Fabric Moisture Permeability Tester The tester operates by placing a fabric specimen over a container filled with water. Under controlled temperature and humidity conditions, water vapor passes through the fabric over a specified period. The amount of water vapor transmitted is determined by measuring the weight loss of the container, allowing for the calculation of the Water Vapor Transmission Rate (WVTR). Common Testing Methods- Upright Cup Method: The fabric covers a cup containing water, and the assembly is placed upright in a controlled environment. After a set duration, the weight loss is measured to determine the WVTR.
- Inverted Cup Method: The fabric is sealed over a cup, which is then inverted and exposed to a controlled environment. The amount of water vapor absorbed by the fabric is measured over time.
- Sweating Hot Plate Test: Simulates human perspiration by measuring the energy required to maintain a constant temperature on a heated plate covered with the fabric, providing insights into the fabric's breathability.
- Multi-Cup Design - Typically includes 6 or more test cups for simultaneous testing of multiple samples.
- Rotating Turntable - Ensures uniform air exposure and consistent vapor transmission across all samples.

What is VeriVide D65 Artificial Daylight?
VeriVide Original D65 Tube light is a standardized daylight illuminant representing daylight with a correlated colour temperature of approximately 6500 Kelvin. VeriVide describes D65 as the international standard measure of daylight based around a mean colour temperature of 6500K.
The purpose of D65 lighting is not simply to provide a bright white light. Instead, it provides a standardized spectral lighting condition suitable for professional visual colour assessment.
Two products can sometimes appear to have the same colour under one light source but look different under another. This phenomenon is known as metamerism. For this reason, professional colour assessment requires controlled and standardized illumination. VeriVide specifically highlights the importance of viewing colour samples under standardized lighting conditions to identify colour differences and metameric effects.
VeriVide Original D65 Tube light is engineered for this type of controlled colour assessment environment.
Why Choose Original VeriVide D65 Tube Light?
Colour evaluation is an important part of quality control in many industries. A small difference in colour can result in rejection of fabric, garments, packaging, printed materials or finished products.

1. Correlated Colour Temperature – 6500K
VeriVide Original D65 Tube light has a 6500K correlated colour temperature.
6500K is the defining colour-temperature characteristic of D65 artificial daylight. It produces a cool daylight appearance suitable for professional colour evaluation.
This is particularly important when colour standards and product samples need to be compared under controlled lighting conditions.
2. High Colour Rendering Index – CRI 98
VeriVide Original D65 Tube light is specified with a CRI of 98.
CRI, or Colour Rendering Index, indicates how accurately a light source renders colours in comparison with a reference light source. A higher CRI is generally desirable for visual colour assessment because it allows colours to be represented more accurately.
For applications such as textile shade matching, garment inspection and product colour comparison, high colour rendering performance is an important consideration. VeriVide lists its D65 lamp with CRI 98.
3. T8 Tube Design
The VeriVide D65 fluorescent lamp is available in T8 format.
The T8 designation refers to the tube diameter/type used by the lamp. The official VeriVide specification lists D65 versions in 600 mm, 1200 mm and 1500 mm lengths, with corresponding 18W, 36W and 58W power ratings.

Application of VeriVide Original D65 Tube light
The VeriVide D65 Artificial Daylight Tube is suitable for applications where standardized daylight illumination is required for visual inspection and colour assessment.
Textile Industry
The textile and garment industry is one of the major applications for D65 artificial daylight.
Textile manufacturers, dyeing factories, garment factories, buying houses and quality-control laboratories need to compare fabric samples, dyed yarns, garments and colour standards under controlled lighting.
Typical applications include:
- Fabric shade matching
- Garment colour inspection
- Yarn colour comparison
- Dyed fabric inspection
- Colour approval
- Lab dip assessment
- Bulk production shade checking
- Colour standard comparison
- Final garment inspection
- Buyer sample approval
Using standardized lighting helps different departments and organizations evaluate the same colour under similar viewing conditions.
Colour Matching
Colour matching requires more than simply checking whether two samples look similar.
A sample may appear acceptable under one light source but show a noticeable difference under another light source. This is particularly important in textile, garment and manufacturing applications.
VeriVide Original D65 Tube light provides a standardized daylight reference for visual assessment.
For example, a laboratory may compare:
Approved Colour Standard → Lab Dip → Bulk Fabric
All three samples can be evaluated under the same D65 lighting condition.
This provides a more controlled environment for colour decisions.
Metamerism Assessment
Metamerism occurs when two colours appear to match under one lighting condition but appear different under another.
This can create serious problems in textile and product manufacturing.
For example:
- Fabric A may match the approved standard under one light.
- Under daylight, Fabric A may appear different.
- Under store lighting, the difference may become even more noticeable.
VeriVide Original D65 Tube light recommends standardized viewing environments because changing illumination can reveal colour differences that may not be visible under another light source.
VeriVide Original D65 Tube light light source can therefore form an important part of a professional colour assessment system.
Use in VeriVide Colour Assessment Cabinets
VeriVide colour assessment cabinets can be configured with standardized light sources including D65 and D50, along with other illuminants depending on the application.
The D65 tube is particularly useful where daylight-standard colour assessment is required.
A typical colour assessment cabinet may contain multiple light sources to allow the operator to check colour behaviour under different lighting conditions.
This can help identify:
- Colour inconsistency
- Metamerism
- Shade variation
- Fluorescence-related appearance
- Differences between product and colour standard
Use in Textile Testing Laboratories
Textile testing laboratories require controlled and repeatable environmental conditions for visual assessments.
VeriVide Original D65 Tube light can be used as part of an appropriate viewing cabinet or visual inspection system for:
- Colour fastness assessment
- Shade evaluation
- Fabric colour grading
- Garment inspection
- Pilling assessment
- Appearance assessment
- Colour matching
- Standard comparison
VeriVide Original D65 Tube light own textile testing equipment uses CIE D65 artificial daylight for standardized visual assessment applications. For example, its Pilling Assessment Viewer uses VeriVide CIE D65 Artificial Daylight for assessment under relevant EN ISO 12945 methods.
Colour Fastness Assessment
Visual evaluation is also important in textile colour fastness testing.
A controlled D65 light source can provide standardized viewing conditions when comparing test specimens with reference standards.
VeriVide's Colour Fastness Cabinet, for example, uses D65 Artificial Daylight at 6500K as one of its standardized light sources, together with UV black light for relevant assessment applications.
Benefits for Garment Manufacturers
For garment manufacturers, colour consistency is essential from sampling through bulk production.
The VeriVide Original D65 Tube light can help establish a controlled visual environment for:
Sampling
Compare the original colour standard with lab dips and development samples.
Production
Check whether bulk production remains within the approved colour range.
Quality Control
Evaluate finished garments before shipment.
Buyer Inspection
Provide a standardized environment for colour approval.
Final Inspection
Reduce the possibility of colour disputes caused by inconsistent lighting.
Benefits for Textile Dyeing Factories
In dyeing factories, colour decisions are often made at several stages.
These may include:
- Recipe development
- Lab dip preparation
- Lab dip approval
- Bulk dyeing
- Shade checking
- Finishing
- Final inspection
- Shipment inspection
Using a standardized VeriVide Original D65 Tube light source can help maintain consistent visual conditions across these stages.
This is especially useful when several people are involved in colour evaluation.
Standards and Compliance
The VeriVide Original D65 Tube light is specified by VeriVide for use as a D65 artificial daylight source.
According to VeriVide's published lamp information, the D65 lamp has a 6500K correlated colour temperature, is within the tolerances prescribed in BS 950 Part 1, and has high conformance to relevant CIE specifications for accurate colour matching. VeriVide's current documentation also references ISO/CIE 23603 / CIE S 012/E for D65 applications.
Depending on the particular testing method, viewing cabinet and industry application, additional standards may apply. Users should always verify the exact lighting requirements specified by their applicable test method, buyer or customer.
Why Standardized Lighting Matters
Natural daylight is not constant.
It can change due to:
- Time of day
- Weather
- Season
- Geographic location
- Atmospheric conditions
- Window orientation
- Surrounding environment
Because of these factors, a colour sample may look different at different times or locations.
VeriVide notes that these natural-light variations can cause colour consistency problems throughout a supply chain. Standardized artificial light provides a controlled alternative.
For international textile and garment supply chains, this is especially important because a buyer, manufacturer and supplier may be located in different countries.
VeriVide D65 vs Ordinary Daylight
| Feature | VeriVide D65 | Ordinary Natural Daylight |
|---|---|---|
| Standardized | Yes | No |
| Colour Temperature | 6500K | Variable |
| Controlled Environment | Yes | No |
| Colour Assessment | Professional | Variable |
| Repeatability | High | Low |
| Weather Dependent | No | Yes |
| Time-of-Day Dependent | No | Yes |
| Suitable for Standardized Colour Evaluation | Yes | Not recommended as sole reference |
The purpose of VeriVide D65 is therefore to provide a more consistent and controlled lighting condition than relying on natural daylight alone.
