The Checkerboard Test Chart is available on matte inkjet, photographic paper, film, and chrome-on-glass substrates. It is designed to work with the Checkerboard module. This module enhances testing of varying distances by supplying more testable regions to provide automated measurements of sharpness, lateral chromatic aberration, and distortion from images.
Learn more about the Checkerboard Module. Please note that this module runs slower than eSFR ISO and SFRplus modules and is less tolerant to extreme amounts of defocus or blooming degradations.

In Visible Spectrum, choose between matte inkjet, reflective photographic or transmissive LVT film substrates. Contrast ratios include 4:1, 10:1 and 45:1 for the inkjet and photographic charts, and additional 100:1 for film targets. All inkjet, photographic, and film options are printed with 12 vertical squares.
Chrome on Glass Checkerboard Targets are available in the “NIR and Visible” category with 10:1 contrast ratio. Choose between a 50.8mm (2″) or 101.6mm (4″) plate with square sizes: 1mm (0.04″) and 30 x 30 squares, 2mm (0.08″) and 15 x 15 squares, 4mm (0.16″) and 7 x 7 or 20 x 20 squares, and 8mm (0.31″) and 10 x 10 squares. Or choose a 25.4mm x 76.2mm (1″ x 3″) plate with three patterns, square sizes, and dimensions of 1.07mm (0.042″) and 10 x 20 squares, 0.53mm (0.021″) and 20 x 20 squares, and 0.28mm (0.01″) and 40 x 40 squares.
Pre-Mounted Checkerboard Charts are also available for use with Imatest Uniform Light Sources.

Documentation and software support
Checkerboard can be run either through the highly-interactive Rescharts interface or as a batch-capable fixed module. The key documentation for getting started is Using Checkerboard Part 1, found in the Checkerboard section of the Documentation page. Checkerboard provides the most accurate distortion measurements.
