Keyline as an overseeing MIS does not interact with any print data files ("the PDF") directly. However, in order to orchestrate the processes of a printery, Keyline stores meta-data about the print data files and can trigger events based on this meta-data. This can be used to ease communication between different tools during the PDF processing and preflight.
Keyline is the central location of all production-relevant data for any print product, and enables streamlining of many more processes of a printery. It does this, among other things, by
However print data management in Keyline not only enables process streamlining, but also informing users about the status of production of any print product, by
Usually there are several tools involved in the processing of print data. However those tools don't integrate well with each other and data between those tools needs to be transferred manually. Keyline provides you with a key/value store for each print data file, that accepts almost any data you provide. With this mechanism you can use Keyline as the primary source of meta-data during preflight and processing tasks, instead of generating and moving XML or other files around.
Keyline not only allows you to store print data file information, but also encourages you to store information about the state of these files. For example, during processing of an original file during which processed files will be created, we recommend that you create the objects for these processed files right away and continuously update their progress and state via the Keyline API. Keyline can then provide the user with this information, allowing her to view all critical information in one place, no matter the underlying PDF processing tool.
Through print data errata, Keyline allows you to track problems during print data processing down to the page level. If you use the Keyline API to store such information you allow the user to easily view problems and devise rescue strategies. This information can also be consumed by proofing portals or mailed to a client.
