Abstract: Queue rendezvous services allow mutual exclusion of processing of certain message types in a generic way without unnecessarily tying up queue resources while waiting for certain conditions to be met and without requiring a queue client to implement application locks to support mutual exclusion processing rules.

Abstract: Disclosed is a method of modifying one or more colors contained in an Encapsulated PostScript (EPS) file in a computer program such as a desktop publishing program (50). After an EPS file has been imported into a publication, all identifiable colors in the EPS file, i.e., spot colors and, in some instances, process colors, are displayed to a color palette (84). The color palette allows a user to see those colors (or inks) that are needed to print the publication, and subsequently modify the colors without having to return to the originating program that exported the EPS file. The method includes creating a publication color list that contains those colors that have been modified, generating a PostScript (PS) color table from the publication color list after the modifications are complete, and changing the attributes of those colors in the PS table while printing the publication to a file or to a printer.
