Abstract: A web inspection module is described for scanning an imprinted web in a printing press. The web inspection module includes a light source for illuminating a portion of the web, a contact image sensor having a plurality of sensing elements, and a processor for receiving and processing image data representative of the imprinted web.

Abstract: An image processing apparatus and method for measuring spatial and spectral information from an image of a printed substrate. The image processing apparatus processes the spatial and spectral information from the same acquired image using first and second processors. One of the first or second processors includes a large format sensor and the other of the first or second processors includes a small format sensor. Both the first and second processors are capable of processing both the spatial and spectral information and neither the first or second processor is necessarily dedicated to processing only the spatial or spectral information.

Abstract: An image processing apparatus and method for measuring spatial and spectral information from an image of a printed substrate. The image processing apparatus processes the spatial and spectral information from the same acquired image using first and second processors. In some embodiments, the image processing apparatus processes the spatial information from a first acquired image and the spectral information from a second acquired image, the first and second acquired images being of the same point on the printed substrate, acquired at separate times during the travel of the printed substrate. In other embodiments, the image processing apparatus processes the spatial and spectral information from the same acquired image using the same processor.
