摘要：Apparatus and method for monitoring print quality produced by a digitalprinting mechanism in real-time. Print quality is measured by: generating a backgroundreflectance 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 apredetermined fraction of said reflectance signal, generating an output signal indicativeof poor quality. In one embodiment of the invention, the output signal is also generatedif the post-print reflectance signal is less than a predetermined minimum value.
