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

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.

The number of reflected light is a measure assigned by a gloss meter as a gloss unit (GU). It is a normalized quantity in which 100 GU is normally a perfect reflection at 60°, and 0° GU is a full diffusion.

Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

Gloss is the general reflectivity of a surface, which encompasses a variety of degrees. One particular type of finish is high gloss, which has the maximum shine and reflectance. It increases the richness but emphasizes flaws as compared to satin or matte.
