The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, and tonal response. 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,
  4. full support for automated testing.


SFRplus charts on photographic paper have the following properties:

  • 5x9 grid pattern
  • Active Area: 223mm x 356mm. It is recommended these charts be used to test imaging systems with sensors up to 3 MP. For larger image sensor sizes, please see other SFRplus chart listings. The active area of the chart includes white space above and below the top and bottom distortion bars. It is typically about 10% larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included because test images of the chart must include this white space in order to enable automated processing in SFRplus software.
  • Contrast levels: 10:1 and 2:1 contrast levels to analyze non-linear signal processing

FAQs About  SFRPlus Test Charts

The gloss meter is used to measure the gloss level: it is a device that directs the light at a fixed angle and reads the intensity of the reflected light. The angles, such as 60°, 20°, or 85°, are applied depending on the type of surface and the range of gloss.


A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..

The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

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


The Colour Assessment Cabinet (CAC) is a controlled environment used for the visual evaluation of color wherein the light sources are consistent.


To answer this question, you first need to clarify your specific needs: 

  • Is it for simple color quality control (QC)?

  • To coordinate with supply chain color management?

  • To monitor on-line color stability?

  • Do you require computer color matching or production color correction?

  • What is your budget?

  • Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.
