Claim One:
1. A system for registering a printing press, said printing press including a plurality of printing stations each for printing a respective color image on a web, each of said printing stations being associated with a respective different color, at least two of said printing stations being un-registered, said system comprising: an imager acquiring an image of a common area of said web, a driver side of said acquired image including at least a portion of at least one color image associated with at least one respective un-registered printing station and an operator side of said acquired image including at least a portion of at least one other color image associated with at least a respective other un-registered printing station; and a processor, coupled with said imager, registering said at least two un-registered printing stations, by registering said at least a portion of said at least one color image with at least a portion of said at least one other color image according to at least one of the following: registering at least two monochrome images, each monochrome image corresponding to a color image printed on said common area, each monochrome image being determined according to the location of each pixel of said acquired image in a color separation space, said location of each pixel in said color separation space being determined according to the projected location of each pixel of said acquired image on a color projection plane, said color projection plane being determined according to the coordinates of the color associated with each said un-registered printing stations and the coordinates of the color of said web in a selected color space; and registering said at least said portion of said at least one color image in said driver side with said at least said portion of said at least one other color image in said operator side with a reference image; said processor instructing an actuator interface to position a plate roller of one of said at least two un-registered printing stations at an angle with respect to an impression roller of said printing press, such that said driver side of said plate roller is in contact with said web and prints said at least a portion of at least one color image associated with at least one respective un-registered printing station; and said processor instructing said actuator interface to position a plate roller of another one of said at least two un-registered printing stations at another angle with respect to said impression roller of said printing press such that said operator side of said plate roller is in contact with said web and prints said at least a portion of at least one other color image associated with at least a respective other un-registered printing station.
