System and method for color measurement and control on-press during printing

摘要

A method for color measurement and control and a color measurement and control system for determining during printing, on-press, the color value of at least one location on a printed substrate. The color measurement and control system includes a camera for acquiring an image of an area of the printed substrate, a color measurement device for measuring a color value of a location of the printed substrate, the color measurement device and the camera are operating substantially simultaneously, and a processing unit for receiving the image captured by the camera and the color measurement and for providing a position of the location with respect to the image employing the image itself. The processing unit is also operative to provide a color value of a desired position, the desired position is selected from the determined position and a position other than the determined position.
