Systems and methods for inspecting and evaluating qualities of printed regions on substrates for absorbent articles

A method for assessing print quality, the method comprising steps of:

• generating an array of scores by soliciting and recording human feedback based on human perceptions of sample printed regions, wherein each score is correlated with at least one inspection parameter defined by a comparison of a sample image of a printed region and a target image, wherein the at least one inspection parameter is selected from the group consisting of:
• grayscale, color, shape, mismatch size, and mismatch location;
• providing a communication network;
• connecting a camera and a spectrophotometer with the communication network;
• connecting an analyzer with the communication network;
• advancing a substrate in a machine direction, the substrate comprising a printed region;
• inspecting the printed region with the camera;
• communicating an image of the printed region from the camera to the analyzer;
• comparing the image with the target image to calculate a first score based on the array for the inspected printed region;
• and
• inspecting the printed region with the spectrophotometer to measure at least one of a delta E and a dot area;
• calculating second score based on at least one of the measured delta E and dot area;
• calculating a full print quality score based on the first score and the second score;
• converting the substrate into discrete articles, wherein at least one discrete article comprises the printed region;
• and
• executing a control action based on the full print quality score.

• calculating a fourth score based on the measured color to color registration;
• calculating a full print quality score based on the first score, the second score, the third score, and the fourth score;
• converting the substrate into discrete articles, wherein at least one discrete article comprises the printed region;
• and
• executing a control action based on the full print quality score.
