One of the main mechanisms that Global Graphics Software Inc. give us all to adapt the powerful Harlequin™ RIP are Page Features. Many Harlequin RIP users will have heard of them, or may recall in the Page Setup dialog box on their RIP a place to select a Page Feature (just called "Feature" in newer editions of the RIP). Page Features are pieces of Adobe Postscript® or Global Graphics extensions to the Postscript language, written in plain text, which can be run by the RIP with each job that is processed through the Page Setup in which they are selected, in order to modify the processing of the job in some way.
