Latest Patents

One of Keith's latest patents is a method and system for color film separation preprocess using electronic means. This invention involves a computer system designed for the production of ink separations from an object-based print pre-process apparatus utilizing a page description language. The system facilitates the creation of object spreads for various configurations of objects on a rendered page. For each object, the computer system employs a spread table to determine spread incidences. It generates set union, intersection, and difference for spreading, receiving, and obstructing objects through a modified Weiler algorithm. This algorithm simplifies the graph of contour histories, providing a visible portion of the spread object. The visible object can be stroked within a clipped window set to the receiving object, with stroke color and width determined by the spread table.
