FAQs About  ISO Test Charts

Yes. Ultrasonic coating thickness gauges can pinpoint layers within a multi-coat system. Users can examine the separate thicknesses of a primer, base coat, and clear coat. In contrast, magnetic and eddy current gauges usually measure the overall thickness of the coating. 

Daylight, store light, home light, and UV fluorescence light sources are included in Pantone light boxes as D65, TL84, CWF, A, and UV. 


3nh Spectrophotometers for Paint Formulation

All these instruments deliver superior performance by measuring precise spectral data, which is the foundation for accurate, repeatable, and cost-saving paint formulation.

A haze meter should be calibrated every 6 months, or more frequently if used for certain quality control processes.


This refers to assessing samples with a specific color and maintaining the same alloted time interval on all parameters to ensure neutrality of variables and reproducibility of lightness in the color. 


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.
