A color control system for maintaining the color of a printed page of a printing press constant, within the context of the human perceptual color space system optimizes the settings of a plurality of ink keys in a printing press in accordance with a test image and a reference image. The test and reference images comprise a plurality of ink key zones corresponding to the plurality of ink keys, each ink key zone including a plurality of regions of interest (ROIs). The system includes a unit for imaging an area of the printed page in generating the reference and test images, a unit for extracting color information based on actual image colors from the test image, a unit for measuring color deviations with reference to the reference image, and a unit for analyzing and comparing global features of regions of interest (ROIs) that cover substantially the color gamut of the test image against like features of the reference image. The analysis and comparison is based on a plurality of ROIs, all located within the same ink key zone, and the analysis and comparing unit operates to generate a set of CMYK changes to be applied to the plurality of ink keys. The system also includes a unit for applying the set of CMYK changes to the plurality of ink keys.

On press color control system

An automatic visual inspection system for small arms ammunition which sorts visual surface flaws at high speed according to established standards which can be tailored to fit specific needs. The system employs advanced techniques for performing inspection independently of human inspectors and allows for quick changeovers in the type of ammunition to which it is applied. The system comprises interface apparatus for receiving a supply of ammunition cartridges and providing each cartridge with a predetermined orientation, conveying apparatus for locating each of the cartridges for inspection in at least one inspection station, apparatus for imaging selected areas of each cartridge to provide video surface feature data associated therewith, and apparatus for processing the video surface feature data to detect the presence of a predetermined set of characteristics and provide output signals in accordance therewith, the conveying apparatus being operated to sort each of the inspected cartridges in accordance with the output signals. A preferred embodiment comprises four subsystems, a feeding subsystem, an imaging and handling subsystem, an operation subsystem, and a computers subsystem. The imaging and handling subsystem provides each cartridge with the necessary orientation for inspection by a video camera feeding video surface feature data to an image processing computer. The image processing computer makes a very high speed computation based on image processing techniques to decide whether the cartridges have manufacturing defects for sorting purposes. Since many surface flaws look the same in two dimensions such as scratches and splits or acid holes and stains, special lighting of the cartridges is used so that discrimination between them can be achieved on the basis of off-specular reflections.
