Abstract: An apparatus for changing the orientation of a control panel of a scanning system to provide maximum convenience according to the orientation of the scanning system on a desktop surface. The apparatus comprises a circular control panel rotatably mounted within the main case of the scanning system, together with one or more spring-loaded mechanisms serving to lock the rotatable control panel module in a position set by an operator.

Abstract: A method for determining the boundaries between regions of color making up polychromatic document pages or images, in order to compensate for misregistration of printing plates in printing, and thereby to prevent light leaks and other errors at the boundaries so determined. A map of the boundaries is generated, to which trapping operations are applied to form a structured graphic object that is included as the last object imaged in the data representing the original image. The geometrical description of the boundary map determined according to the method of the invention is independent of specific trapping decisions applicable to the associated image.
