Control The Every-changing Colors

When testing product color or color matching in production process, different light sources, illuminance, color temperature and environmental changes make the naked eye make wrong judgment on color.

Color light box can provide accurate and objective standard light source environment for raw material production or product color comparison.

The 3nh color - matching cabinet features a seamless structure design. It is 100% light - tight, preventing interference between light sources. The light sources can switch automatically, and it has a metamerism - detecting function. No pre - heating is required, and there is no flickering, ensuring fast and reliable color evaluation.

Introduction to Standard Light Source Color Matching Cabinets

Definition:

A tool used for comparing and evaluating color accuracy. Different light sources can cause objects to appear in different colors, especially indoors or at night. To address this, color inspection of goods must be conducted under consistent light sources and controlled conditions.

Key Functions:

Provide Standard Lighting Environment

Simulate multiple international standard light sources (D65, D50, TL84, TL83/U30, UV, F, CWF, A), eliminating ambient light interference to ensure objective and repeatable color evaluation.

Identify Metamerism

Detect "metamerism" (color matching under one light source but not another) by switching between light sources (e.g., D65, UV), revealing differences in dyes or formulations.

Ensure Color Consistency

Compare colors of raw materials, finished products, packaging, etc., in industrial production to ensure batch-to-batch color uniformity.

Improve Quality Control Efficiency

Assist quality inspectors in quickly identifying color deviations, reducing risks of rework and returns caused by color discrepancies.

Standard Light Source Color - Matching Cabinets VS Traditional Lighting Sources

	Standard Light Source	General lighting
Core Function	Professional color detection, simulating a standard light source environment	General lighting, meeting basic brightness and ambient needs
Light Source Diversity	Supports multi - light source switching (such as D65, A light source, etc.)	Single light source (mainly warm or cool light, non - customizable switching)
Color Accuracy	Extremely high (high color rendering index of the light source), reducing color errors	Low (low color rendering index of the light source), large color deviation
Cost	High (equipment + maintenance)	Low (procurement)
Applicable Scenarios	Color - sensitive industrial quality control, e.g., textile, printing, plastics, etc.	General lighting scenarios, e.g., home, office, commercial spaces, etc.

For industries with high requirements for color accuracy, standard light source color - matching cabinets are essential tools.

Application of Standard Light Source Color - Matching Cabinets

Applicable Scope: Textile, garment, plastic, toy, paint, ink, pigment, printing, dyeing, packaging, hardware, photography, ceramics, leather, food, cosmetics and other industries.

Industry	Applications
Textile, Apparel	Detect the color consistency of fabrics, dyes, and finished garments under different light sources (such as daylight, showcase spotlights) to avoid color - difference disputes in orders.
Printing, Packaging	Calibrate the color of ink to ensure that the design drafts match the colors of actual printed products in environments like cool white light and warm light.
Plastic, Plastic Products	Detect the color stability of plastic pellets and injection - molded parts (such as automotive interiors) to avoid color deviations caused by raw material batch differences.
Paint, Coating, Chemical Industry	Calibrate the formula of coating color pastes to prevent the "metamerism" problem.
Automobile Manufacturing, Parts	Calibrate the color of car body paint and interior material colors to ensure that parts provided by different suppliers match in color under a unified light source.
Leather, Footwear Materials	Detect the color fastness of leather fabrics and footwear auxiliary materials to ensure the color display effect of finished shoes in scenarios such as shopping mall spotlights and outdoor showcases.
Cosmetics	Evaluate the color stability of products like lipsticks and eyeshadows, as well as the visual effect of packaging colors in the retail environment.
Food	Detect the colors of packaging and products (such as beverages, meats) to avoid the impact of lighting differences on consumers' judgment of product quality.

Usage Precautions for Standard Light Source Color - Matching Cabinets

Observation Angle

During color inspection, differences in the observation angle can also affect the color assessment results.

Zero - degree light source, 45 - degree observation (0°/45°);
45 - degree light source, zero - degree observation (45°/0°).

Sample Placement

Place the sample in the middle of the cabinet as much as possible to reduce the interference of external light.
Avoid overlapping samples as much as possible. Grey baffles can be used to cover the samples to reduce interference between them.

FAQs About Light Booth

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.

Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.
