Abstract
A method of detecting color miscalibration in a color output device. Accordingly, the method includes providing a calibration mask having a target color and a plurality of windows, and outputting a test array that includes a plurality of test samples arranged for viewing through the windows of the calibration mask, wherein each test sample has an associated test color. The windows may be at least partially aligned with at least one of the test samples, and the target color of the calibration mask may be compared to the test colors of the framed test samples.
