Abstract
Apparatus and method for monitoring print quality produced by a digital printing mechanism in real-time. Print quality is measured by: generating a background reflectance signal representative of the reflectance of a substrate; scanning the image to generate a post-print reflectance signal; comparing the reflectance signal with the post-print reflectance signal; and, if the post-print reflectance signal is greater than a predetermined fraction of said reflectance signal, generating an output signal indicative of poor quality. In one embodiment of the invention, the output signal is also generated if the post-print reflectance signal is less than a predetermined minimum value.
