A 4x6 array of 2" colored squares used for calibrating and evaluating color reproduction systems. The ColorChecker is 8.5"x11.5" proportioned to fit a 35mm frame.

One of the most photographed images in the world, the ColorChecker is a unique test pattern scientifically designed to help determine the true color balance of any color rendition system. It allows you to avoid costly mistakes by checking for potential problems.

Some of its applications include:

• Photography: Check films, lights, filters and paper.
• Graphic Arts: Check any printing or proofing process.
• Electronic Publishing: Check scanners, monitors and proofing devices.
• Television: Check cameras, monitors, lights and film.

The ultimate goal of any process of photography, electronic publishing, printing or television is to reproduce all colors perfectly. To help make meaningful judgments about color rendition, a totally non-subjective standard of comparison is needed. That is why the GretagMacbeth ColorChecker chart was developed. It provides the needed standard with which to compare, measure and analyze differences in color reproduction in various processes.

The ColorChecker is a checkerboard array of 24 scientifically prepared colored squares in a wide range of colors. Many of these squares represent natural objects of special interest, such as human skin, foliage and blue sky. These squares are not only the same color as their counterparts, but also reflect light the same way in all parts of the visible spectrum. Because of this unique feature, the squares will match the colors of natural objects under any illumination and with any color reproduction process.
