Determining the color repeatability of images from color output devices is paramount for color-critical applications. Color should be described in coloriinetric values which are then used to make a probability statement about printed color repeatability. Experiments are described that determine color repeatability for a four color continuous ink jet printer using colorimetric methods and probability ellipses. CIELab measurements were taken from several ink jet prints which contained a standard test image. The test image consisted of an array of color patches with different colorant amounts. Two-dimensional ellipses, representing the 95% a*,b* confidence interval, were then computed for each color patch to establish color repeatability. Typical results showed that ellipse axes were not parallel to the a*,b* axes, suggesting that simple a*,b* tolerances would lead to an inaccurate repeatability statement.
