The short answer is no. CSA/CSD goes through XYZ, and 3 channels is not 4 channels. You have to use some other mechanism within the particular interpreter to achieve device link support. For instance, JAWS has a driver architecture that lets you substitute for the CAS/CSD machinery in a way that will support device links, and CPSI has a poorer set of extensions called "Proofer Plug-In" and "DeviceN Process Color Model" that can also be turned to the same purpose with some effort (been there, done that.) I'm not sure if Ghostscript has a similar mechanism or not. Graeme Gill. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
