Abstract:
1. A method of coordinating the use of a color control system and a defect detection system on a printing press having a plurality of ink key zones and printing using a plurality of ink colors, the method comprising: acquiring image data from a printing press, determining an actual color difference between the acquired image data and template image data representative of a desired image for each of a plurality of pixels, summing the actual color differences of the plurality of pixels to obtain a sum of defects, computing ink key adjustments for each ink key zone and for each color from the actual color differences, computing predicted image data from the ink key adjustments, determining a predicted color difference between the predicted image data and the template image data for each of the plurality of pixels, summing the predicted color differences of the plurality of pixels to obtain a residual error, and enabling and disabling the outputs of the defect detection system based on the sum of defects and the residual error.
