Abstract
Systems and methods may automatically evaluate printed line weights in an image composition. An image composition may be received and the number of horizontal and vertical rows of pixels may be determined. The number of positive pixels in each of the horizontal and vertical rows may then be determined. An actual size of a pixel may be calculated. The actual size of a pixel may be multiplied by the number of positive pixels in each of the horizontal rows and each of the vertical rows to determine a positive line weight of each of the horizontal rows and each of the vertical rows. A predetermined minimum permissible positive line weight for the image composition may be identified and compared to the positive line weight of each of the horizontal rows and each of the vertical rows.
