A document that contains a standardized series of color patches and geometric patterns, it enables the assessment and adjustment of a scanner’s color accuracy and geometric precision. These sheets, typically available in digital formats, serve as a reference point for evaluating and correcting deviations in color reproduction and distortion introduced by the scanning process. For example, an IT department might utilize this reference material before a large document digitization project to ensure consistent and reliable image quality.
The use of such standardized references offers several benefits. It ensures consistency in color reproduction across multiple scans and scanning devices. Accurate color representation is crucial in fields such as graphic design, archival preservation, and medical imaging. Moreover, these resources help to mitigate the effects of scanner drift, which can occur due to component aging or environmental factors. Historically, these reference materials were primarily physical prints; however, the digital distribution format facilitates wider accessibility and reduces the potential for physical degradation of the reference itself.
