An image processing apparatus for use with a printed image on a moving substrate is provided. The image processing apparatus includes a first imaging device configured to process spatial data which indicates a position of color patches printed along an edge portion of the printed image on the moving substrate. The image processing apparatus further includes a second imaging device configured to process at least one of densitometric data and colorimetric data of the color patches of the printed image. The first imaging device and second imaging device acquire image data from substantially the same position on the substrate at substantially the same time. The image processing apparatus further includes a processor configured to monitor a color of the printed image on the moving substrate based on the spatial data and the at least one of densitometric data and colorimetric data.

Measuring color on a moving substrate

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.
