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

Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample.

High Measurement Accuracy and Stability: Low ΔE fluctuation (e.g., NH300: ΔE < 0.07; NR10QC: ΔE ≤ 0.03 short-term repeatability); Reliable sensors (CMOS dual-beam/silicon photodiode) and long-lasting light sources (1.6M–3M measurements over 5 years).

User-friendly Design and Convenient Operation: Intuitive interfaces (e.g., NH300’s “fool-proof” operation), auto-calibration, and ergonomic grips for extended use; Versatile positioning (light/cross alignment) for precise measurements.

Robust Design: Our colorimter instruments are designed to withstand rigorous use, providing long-term reliability. Rechargeable lithium batteries enable 5,000–6,000 measurements per charge (e.g., NH300/TS7030), ensuring cost-effective durability.

PC Software Support for Functionality Expansion: PC software (e.g., CQCS3) supports color difference analysis, chromaticity indexing, and sample library management.

Global customer support: Our global presence across regions ensures you get the service and maintenance support you need to keep your instrument at peak performance.

Multiple Measurement Apertures and Application Scenarios: Multiple measurement apertures, different models have different measurement apertures and some models offer multiple optional apertures. Applicable to plastic electronics, paint and ink, textile and garment printing and dyeing, printing, ceramics, automotive, food, medicine and other industries for color quality control and color difference detection.

Now our testing machines have been sold to more than 80 countries, like USA, Canada, Russia,UK, Italy, Germany, European , India, Pakistan, Philippine, Singapore, Malaysia,Thailand , Vietnam, Korea,Saudi Arabia,Brazil...and so on. We sell to the global market.

D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
