The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, tonal response, and color accuracy. The SFRplus module features fully automated region-of-interest detection. The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including 1) much less wasted area, 2) the ability to produce a map of sharpness over the sensor surface, 3) better measurement accuracy due to the lower contrast, and 4) full support for automated testing.

This chart is recommended for most standard testing setups and devices. Choose a size based on your sensor and setup limitations.


Options include:

  • Grid: 5x9 grids are recommended for for typical DSLR formats with aspect ratios of 3:2
  • Paper Size and Active Area Options

    This chart is available in three sizes. It is recommended that the medium sized charts be used to test imaging systems with sensors up to 12 MP, the large charts be used for testing of sensors up to approximately 24 MP, and the extra-large charts be used for sensor sizes above 24 MP.

    Active Area

    The active area of the chart includes white space above and below the top and bottom distortion bars. It is slightly larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included in active area because test images of the chart must include this white space in order to enable automated processing in SFRplus software.

  • Paper/ink type: Matte paper/ink can be used to reduce reflected light and allow for easier lighting setups
  • Contrast levels: 4:1 contrast ratio for new ISO standard compliance
  • Color chart: a 20 patch color chart.

FAQs About  SFRPlus Test Charts

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses


Different types of substrates require different kinds of digital gauges. Magnetic gauges are for ferrous metals, eddy current gauges are for non-ferrous metals and ultrasonic gauges are for any non-metal composites like plastics. Careful selection of a gauge is the most important factor for obtaining accurate measurements.  


Standard light sources make sure that the results of color evaluations are comparable and consistent, no matter when and where the assessments are made, or the varying production runs.


Colorimeters have fixed wavelength filters and LEDs; it is less precise and simpler. Monochromators are applied to spectrophotometers, which scan a spectrum of wavelengths. Giving more detailed spectral information. Spectrophotometers are more sensitive and flexible in complicated analyses.


Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

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.
