FAQs About  Geometric Test Charts

Always a pre-production sample before mass production; Always final Inspection before shipment; 

Because of its unmatched precision, ease of use, adherence to global standards, and consistent long-term reliability.


The measurement of color varies according to context in several units. Such common units are L*a*b* (CIELAB), RGB (Red-Green-Blue), and color difference (Delta E). In light absorption, there are no units assigned to absorbance. But the quantitative analysis of absorbance obeys Beer's Law in colorimetry.

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.

Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color. 


The gloss meter is used to measure gloss at typical angles (typically 20°, 60°, or 85°). The instrument illuminates the material and measures the amount of light reflected and states the outcome in gloss units (GU), which is related to perceived brilliance.
