SFRplus Test Charts on Color High-Precision LVT Film
These charts are produced with a high-precision LVT film recording process for the best possible density range, low noise, and fine detail. We have multiple options available including Small (Half Sheet), Medium (Full Sheet), and Multi-Size (Full Sheet) targets.
Due to the aspect ratio of the 5 x 9 charts, we only offer this version in the Multi-Size format. Our Multi-Size option makes maximal use of the film space to provide a variety of different sized charts.
Details
These charts contain SFRplus test patterns with 4:1 contrast and grayscale and color patterns, produced with a high-precision LVT film recording process for the best possible density range, low noise, and fine detail. The Multi-Size versions contain 5 different sizes all printed on one sheet of film. The small and medium options are a single size, as indicated in the table below.

Automated image quality analysis
Our proprietary, ISO-compliant SFRplus charts are designed to work with Imatest software to provide automated, comprehensive image quality analysis.
- Less wasted area: SFRplus charts make use of the entire chart space, while only about 10% of the standard ISO chart area provides useful information for computerized analysis.
- Reduced clipping of high-contrast edges: Making SFRplus test charts more accurate and consistent and less affected by overexposure and underexposure.
- More signal processing information: Allowing measurement of the effects of signal processing, such as sharpening and noise reduction that you would not be able to collect with an ISO chart.
- Automated Region Detection: Automatically identify regions of interest without manual input.
- Variety of sizes and substrates: From 5 x 5 cm to 110 x 187 cm, printed on Matte, Semigloss, or Backlit Media (DisplayTrans) or Photographically Printed Charts on paper or film and even chrome on glass targets for the highest precision needs.
SFRplus tests for:
- Noise
- ISO Sensitivity
- Color Accuracy
- Texture Response
- Distortion and Geometry
- Resolution and Sharpness
- Gamma and Tonal Accuracy
- Lateral Chromatic Aberration
