This ISO 12233:2014 Edge SFR(eSFR)Test chart Instrument are Certified with

1 Years Warranty (Additional support period of 3 years)

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

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

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

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

Always a pre-production sample before mass production; Always final Inspection before shipment;

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

A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.

A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.

Color measurement methods involve visual approximation (against color charts), colorimetry (by means of filters and detectors), spectrophotometry (a more detailed spectral analysis), and image analysis by computer. These are color measurement methods that are applied in the laboratory, production, and quality assessment.
