Color Measurement Service

Color measurement is a scientific process that quantifies the color attributes of materials through objective, standardized methods. It is a critical tool in various industries, including environmental science, where it is used to analyze and ensure the consistency, quality, and performance of environment-friendly materials. By measuring color, we can assess the impact of environmental factors on materials, monitor degradation, and ensure that products meet specific ecological standards.

What is Color Measurement?

Color measurement is grounded in the psychophysical sensation of color perception, which involves the interaction of light with a material and the subsequent detection by the human eye or a scientific instrument. The principles can be broken down into several key components:

Light Source

The electromagnetic radiation that illuminates the material, defined by its spectral distribution and correlated color temperature. Standard illuminants, such as Illuminant A, C, and D65, are used for consistent comparisons across different lighting conditions.

Measurement Geometry

This refers to the angles at which light is incident on the material and detected. Geometries such as 0/45° and d/0° are used to account for the way light interacts with the material's surface, including diffuse and specular reflections.

Observer

The standardization of the human observer in color measurement is crucial. The CIE has defined standard observer functions to simulate average human color perception.

Object

The material itself, which modifies light through reflection, transmission, absorption, and other physical processes. Materials can be classified as opaque, translucent, or transparent, each requiring specific measurement techniques.

Why Do Color Measurement?

Consistency and Quality Control: Color measurement ensures that materials meet specific color standards, which is vital for maintaining product consistency across different batches and production runs.
Environmental Impact Assessment: By monitoring color changes, we can assess the impact of environmental factors such as UV exposure, which is crucial for the development of environment-friendly materials.
Product Development: Color measurement aids in the formulation of new materials that are designed to be more resistant to environmental degradation, thus reducing their ecological footprint.

Our Services

At CD BioSciences, we offer a comprehensive color measurement service tailored to the needs of environment-friendly materials analysis. Our services are designed to provide precise, reliable, and repeatable data to support research and development in sustainable materials.

Methods of Color Measurement

Spectrophotometry

Using advanced spectrophotometers, we measure the color expressed in CIELAB values, providing a comprehensive analysis of color attributes.

Colorimeters

For more focused color measurement, we employ colorimeters that offer rapid and accurate color analysis.

Sample Requirements

To ensure accurate measurements, samples should meet specific requirements:

Surface Area: Samples should have a minimum flat surface area, typically at least 5×3 cm.
Conditioning: Samples may need to be conditioned under specific environmental conditions prior to measurement.
Surface Finish: The surface should be smooth and uniform to avoid measurement inconsistencies.

Color measurement services can be applied to a variety of materials, including:

Opaque Solids

Ceramics, plastics, and metals.

Translucent Materials

Glass, films, and certain plastics.

Liquids

Paints, coatings, and food products.

Workflow of Color Measurement

Sample Preparation: Ensuring samples are clean and free of any contaminants that could affect color measurement.
Measurement: Using spectrophotometers and colorimeters to capture color data.
