A process and system for depicting a combination of process colors and spot colors on a radiant light source such as a computer monitor screen. The invention provides a user-definable "meta-ink" color which is made up of the components of the process colors and the spot colors. Shade values are assigned to each of these components to create the meta-ink color. This meta-ink color then replaces the document color for visual depiction on the radiant light source. This process and system provides a more accurate depiction of the representation of the printed image.

The method for determining component dimensional information according to claim 1 further comprising: determining from said dimension(s) a location of a centroid of said component and storing said centroid location in said component database. 3. The method for determining component dimensional information according to claim 1 further comprising: determining the presence of an array of solder connections on said component centered at said centroid; determining whether or not each of said solder connections has a mirror image solder connection in said array; identifying each solder connection not having a mirror image solder connection; and storing the location of said solder connection not having a mirror image solder connection as a position identifying orientation feature of said component in said component database. 4. The method for determining component dimensional information according to claim 3, further comprising: locating with said camera solder connections which are furthest from said centroid; and storing position data for said solder locations in said component database. 5. A system for determining component dimensional information comprising: a component grasping tool positionable in at least first and second directions; a camera having an aperture which is parallel to a plane defined by said first and second directions, said camera generating a plurality of pixels representing an image of a surface of said component; a vision machine comprising a work cell controller connected to said component grasping tool for positioning said component grasping tool in said first and second directions, and connected to said camera, and an image processor and a component database, said work cell controller being programmed to execute the following steps: incrementally positioning said component being grasped by said component grasping tool over an aperture of said camera; processing said plurality of pixels with said image processor to locate first and second edges of said component; indexing the position of said component grasping tool until third and fourth edges of said component are visible in said camera aperture; based on the change of position of said grasping tool and the position of pixels which detect said third and fourth edges, determining the location of first and second diagonal corners of said component and a centroid of said component; and storing the location of said centroid in said component database. 6. The system according to claim 5 wherein said work cell controller is further programmed to calculate and offset between a position of said grasping tool with respect to said centroid, and to store said offset in said database. 7. The system according to claim 5 wherein said work cell controller is programmed to compute the length and width of said component from said positions of said edges, and to store said length and width in said database. 8. The system according to claim 5 wherein said work cell controler further executes the steps of: identifying from said pixels an array of solder connections on said component; identifying from said pixels solder connections which do not have a mirror image counterpart in said array; and storing the location of said solder connections which do not have said counterpart in said database. 9. The system according to claim 8 wherein said work cell controller is programmed to execute the steps defining a grid which locates rows and columns of said solder connection said grid having coordinates which are within a predetermined range of the actual location of said solder connections.
