The concept of Interoperability Conformance Specification of “ICS” documents is introduced. No single device (i.e., printer, press, imagesetter, etc.) is likely to implement all that the JDF specification provides for. For instance, if you are in the digital printing business, you might not care to facilitate data used for case binding. A RIP is not a requirement for facilitating JDF preflighting. A Stitcher probably doesn't need to handle image rendering data. To specify exactly what individual classes of devices need to do with JDF, CIP4 members are developing ICS document that will provide the minimum expectations for individual classes of devices.
