The YE111 flesh tone test chart is designed for evaluating the flesh tone rendition of electronic cameras. The picture shows the portraits of three women with ideal and critical flesh tones.

The picture areas marked with circles

The picture areas marked with circles have the following color coordinates in the CIE-L*a*b*-system:

  L* a* b*
woman left 75.27 19.45 27.46
woman middle 78.04 12.50 16.65
woman right 83.26 10.18 13.49
 

Utilization

The test transparency is designed for matching several color cameras to an approximately uniform color rendition of human flesh tones.

To operate the haze meter, first calibrate the instrument, clean the sample, position it correctly in the holder, and initiate the measurement. The instrument then shows the haze and overall transmittance readings.

The automotive, aerospace, metal finishing, marine, construction, and manufacturing industries utilize and rely on coating thickness gauges the most. They ensure that coatings are within the expected criteria for functionality, safety, and durability.


A calorimeter is used to measure heat that is gained or lost during a chemical or physical reaction. A sample is taken in an insulated container, and a temperature change is measured. This assists in computing the alterations in energy by the equation Q = mcΔT, where Q is heat.


During color evaluation, maintaining consistent light sources and viewing conditions is critical. Standard viewing conditions vary depending on the object being evaluated, including factors such as brightness, illumination angle, and observer position. Accurate evaluation can be achieved by establishing a proper environment that meets these requirements.

In development and production sites with extremely high color requirements, such as the automotive and cosmetics industries, accurately reproducing colors is essential. Color evaluation helps determine whether the color matches the intended image or target color. It is the process of measuring color, analyzing its characteristics, and evaluating how well it aligns with a specific target color. 

color measurement and color evaluation

Visual Color Evaluation

Color differences are compared visually using standard light sources or reference colors (such as color cards). This method allows color confirmation under conditions close to natural light, making it ideal for color inspection in design and production processes. 

Instrumental Color Evaluation

Measurements are performed using a spectrophotometer or colorimeter. This method eliminates the subjective influence of the operator and is widely used for product quality control and industrial applications, enabling scientific quantification of color.


Color evaluation is widely used across industries such as product development and quality control departments in manufacturing. 

Typical applications include: 

  • Automotive Industry

    Used for quality evaluation of automotive paint, exterior parts, and interior components.

  • Coatings & Materials Industry

    Used to maintain and manage color accuracy for coatings, plastics, glass products, and more.

  • Cosmetics Industry

    Used to verify color consistency in products such as lipsticks and foundations.

  • Molded Products (Resin & Plastics)

    Used to evaluate color difference and uniformity of surface effects in finished products.

  • Furniture & Building Materials Industry

    Used to ensure color consistency in materials such as wood and plywood. Food & Pharmaceutical Industry Used to assess color consistency of food packaging and color differences in pharmaceutical capsules.

Calibrating a colorimeter before testing is critical for accurate, reliable color data—counteracting instrument drift, environmental interference, and component wear to ensure measurements reflect true sample colors. It guarantees compliance with industry standards, eliminates costly rework from flawed data, maintains brand consistency across batches/locations, and ensures data comparability with clients or regulators.

Calibrating a colorimeter before use is primarily to ensure the accuracy of measurement data and compensate for errors caused by the aging of internal components (such as light sources and phototubes) or environmental changes.

Below are the specific reasons: 

  1. Compensation for Component Aging and Environmental Influences

  2. Compensation for Environmental Factors

  3. Standardization of Measurement Baselines

  4. Operational Specification Requirements

3nh colorimeters are designed for immediate measurement upon startup. However, calibration (via black-white correction) is mandatory for the first use, sudden environmental changes, or abnormal data to restore measurement accuracy.

A haze meter measures the light.  It quantifies the measure of transmitted light across a material and the degree of scattered and diffused light.
