The NIR (Near Infrared) Checkerboard Test Chart is available on matte inkjet, reflective photographic, 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.

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.
