SineImage ISO 12233:2014 E-SFR charts are implementations of the Low Contrast Edge SFR (E-SFR) test chart illustrated in Section 6.1 and Annex Cof the ISO Standard Document. The charts come in three versions:

  • Standard: basic, no extra measurement features

  • Enhanced: extra squares, wedges, and color patterns when printed with technologies that allow color

  • Extended: similar to Enhanced, but with a 16:9 aspect ratio, suitable for HDTV and cinema

We currently offer these charts in inkjet format, with Enhanced versionsavailable as photographic prints. All SineImage ISO 12233:2014 E-SFR charts are fully compliant with the ISO standard. The Imatest eSFR ISO moduleprovides highly automated support for the new charts.

Standard Version

 
Standard Version

This chart, which has a 3:2 aspect ratio, is a "no-frills" implementation of the standard. For most work we recommend the Enhanced or Extended charts, which have additional edges for measuring performance near the image boundaries, as well as hyperbolic wedges and color patches (where the technology allows). These chartsmaintain full compliance with the standard.

The Imatest Standard ISO 12233:2014 E-SFR chart closely resembles the Low contrast E-SFR test chart illustrated in section 6.1 and Annex C of the ISO standard document, with a few differences, all of which are fully compliant with the ISO standard.

  • A 20 patch OECF grayscale pattern* is used instead of the 16 patch version.
  • The Focus Patterns in the centers of the squares are rectangular (to increase the MTF measurement area) and are designed to reduce interference with automatic edge detection.
  • There are four registration marks instead of three to facilitate automated region detection. (Four features are required for a projective transform.)
  • An additional mark above the lower-left registration mark is used for detecting chart orientation.

Enhanced Version

 

Enhanced Version

The Imatest Enhanced ISO 12233:2014 E-SFR chart has all the features of the Standard chart, keeping the 3:2 aspect ratio, with the addition of six added slanted squaresfor measuring performance near the image boundaries and hyperbolic wedges for visual analysis or analysis with the Imatest Wedge module. It also has 16 color patches when produced with technologies that allow color. Since these additions are in regions of the chart not covered by the standard, compliance with the standard is unaffected.

The differences between the Imatest charts and the chart illustrated in the standard are listed below. Even with these differences the Imatest chart is in full compliance with the standard.

  • A 20 patch OECF grayscale pattern* is used as opposed to the 16 patch version.
  • The Focus Patterns in the centers of the squares are rectangular (to increase the MTF measurement area) and are designed to reduce interference with automatic edge detection.
  • There are four registration marks instead of three to facilitate automated region detection. (Four features are required for a projective transform.)
  • An additional mark above the lower-left registration mark is used for detecting chart orientation.
     

The differences between the Enhanced and Standard Versions are as follows:

  • Six extra slanted squares are added for measuring performance near the image boundaries.
  • Several hyperbolic wedges with spatial frequencies, similar to the CIPA chart referenced in the ISO standard, for visual analysis or use with the Imatest Wedge module.
  • 16 color patches when produced with technologies that allow color (inkjet or color LVT), with colors similar to the industry-standard 24-color test chart.
     

This chart will work with the fully-automated eSFR ISO module.

 

Extended Version

 

Extended Version

The Imatest Extended ISO 12233:2014 E-SFR chart has all the features of the Enhanced chart (six extra squares, wedges, and 16 color patches where possible), but has a16:9 aspect ratio, which makes it suitable for HDTV and cinema measurements (and it also works well with 3:2 aspect ratio DSLRs). It is fully compliant with the standard.

This chart will work with the fully-automated eSFR ISO module.

FAQs About  ISO Test Charts

Yes. We can supply OEM and make customized design for any specific application. Our MOQ for OEM and ODM service is 5 pcs for one model. We can not only offer standard machines, but also customized machines. Don’t hesitate to tell us your requirement, we will try our best to meet your needs.

A colorimeter is sufficient when measuring similar materials or batches with stable conditions. Suitable for fast, low-cost color checks where high precision is not required. Quick quality control in plastics, paint batch consistency, food color grading (e.g., fruit ripeness), and basic printing checks.

A spectrophotometer is recommended when you need professional, maximum color accuracy or when testing materials with variable surfaces – such as glossy or textured samples. Like textile dye formulation, cosmetic shade matching, medical device color calibration, high-end printing (e.g., packaging for luxury goods), and material spectral research. learn more Understanding Spectrophotometric Parameter Measurement


Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.


Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.


When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.


The Ideal Accurate and User - Friendly Spectrophotometer for Your Needs 

This Spectrophotometer device measures the reflectivity，absorbance, transmittance, and fluorescence of light passing through samples, providing invaluable data for a wide range of applications, provide unrivaled accuracy for reliable results. 

Selecting an appropriate spectrophotometer offers significant advantages for precision color analysis and quality control. When choosing an accurate and user - friendly spectrophotometer, consider factors such as wavelength range, sensitivity, sample handling options, and available software features. By investing in the right spectrophotometer, you can streamline your analytical processes, obtain more accurate results, and enhance the overall efficiency of your laboratory or industrial operations. 

 Choosing the right model—whether portable, benchtop, or inline—aligns technology with specific industry needs, ensuring long-term reliability and optimized color management.
