Abstract: 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.

Abstract: A spring nut assembly is inserted within the internal cavity of a shank tube until the nut is aligned with opposing side holes in the side walls of the shank tube. The spring maintains the nut in alignment with the opposing side walls. A hitch pin including a threaded portion for engaging the spring nut assembly is inserted through the side holes of the receiver tube and the shank tube until the threaded portion of the hitch pin engages the nut mounted within the shank tube. The hitch pin is then rotated relative to the nut to clamp the shank tube against the receiver tube. A lock or clip can be attached to the end of the hitch pin to prevent accidental or unauthorized removal of the hitch pin from the receiver assembly. A bushing can also be used over the reduced diameter portion of the hitch pin after it engages the nut.
