The  Spilled Coins chart (a variant of the Dead Leaves chart) for measuring texture sharpness has several advantages over older Dead Leaves charts. Key features:

  • The Scattered Coins pattern in the central region is almost perfectly scale-invariant (unlike conventional dead leaves charts), enhancing the accuracy and robustness of MTF measurements so they correlate well with other methods (such as the slanted-edge) for RAW images (which have no nonuniform or nonlinear processing).
  • Maximum contrast range is 3:1, as called for in the CPIQ Phase 3 draft Texture Blur Metric draft specification.
  • It is more uniform, i.e., is more shift-invariant than other Dead Leaves charts.
  • It contains slanted edges (2:1 and 4:1 contrast) for convenient comparisons with the dead leaves pattern.
  • The gray area to the left and right of the dead leaves pattern has the same mean density as the dead leaves pattern, allowing it to be used for effective noise PSD removal using the McElvain et. al. technique.
  • Registration marks and 16 grayscale patches are included. The linear levels used to create the grayscale patches are 0 through 255 in steps of 17 (same as the Siemens Star chart in the draft of the upcoming ISO 12233 standard).
  • Imatest Spilled Coins equivalent of the Image Engineering TE-265 referenced in the Skype spec is the Large, Matte ISC0024

FAQs About  Texture Test Charts

 The five common gloss levels are:

1. Flat/Matte (0–10 GU)

2. Eggshell (10–25 GU)

3. Satin (26–40 GU)

4. Semi-gloss (41–70 GU)

High Gloss (71–100+ GU)
These levels vary slightly depending on industry and standards used.


Replace when the total hours exceed rated life, decrease in brightness, or the color temperature shifts beyond tolerance.


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.

Keep light booths clean, maintain the light source lamps, readjust the calibrated light source, and ensure that dust and fingerprints do not settle on the viewing area.


D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries. 

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.
