`Kodak NexPress Developer’s Interface Guide, For System 14.0, Version 14.0
`
`1 Introduction
`The NexPress digital production color press is designed to handle a wide range of applications from short-run and quick
`turnaround, to variable data printing. It uses an open and standards-compliant architecture to integrate existing software
`applications. The NexPress digital production color press is driven by the NexPress front end controller. The NexPress
`front end is a scalable and open PDF-based product. It supports hot folder and JDF/JMF-based job submission and JMF-
`based job and press management.
`Some of the key features of the NexPress front end are:
`ƒ
`Built upon Adobe® PDF-based workflow architecture
`ƒ
`Scalable hardware
`ƒ Accepts Job Definition Format (JDF) Job Tickets
`ƒ
`Supports hot folder submission
`ƒ
`Supports common static page description language (PDL) formats including Adobe® PDF, Adobe® PostScript.
`ƒ
`Provides JDF/JMF interface for Job Ticket submission, queue management, and status messaging. (Submission
`of a JDF Job Ticket can reference either PDF or Postscript content.)
`Supports variable data printing using ANSI Standard PPML/VDX.
`
`ƒ
`
`1.1 Scope
`This document is one of two used by third party software developers who design software controllers and output
`drivers that target the NexPress family of digital production color presses. The complete set of documents is:
`ƒ Kodak NexPress Developer’s Interface Guide [KNDIG] (This document)
`ƒ Kodak NexPress Developer’s Interface Reference [KNDIR]
`The Kodak NexPress Developer’s Interface Guide is the main user document. It references the [KNDIR], and
`provides user description of the various job submission, job management and press management operations for the
`NexPress front end. This guide also identifies the various content formats for the NexPress products, and describes
`the job submission methods and control interfaces using these content formats. Detail on the specific formats is
`provided in the [KNDIR].
`The Kodak NexPress Developer’s Interface Reference provides technical detail on interfaces used in JDF and
`PPML/VDX submission and in control of the JDF portal. This technical companion document to the [KNDIG] is
`intended as a reference. The syntax and semantics of Device Capabilities, JDF Intent, JDF Process, JMF and
`PPML/VDX used by the NexPress front end is provided within this reference document.
`These documents do not describe the interface between the NexPress front end and print engine. This interface is not
`intended to be accessible to third-party workflow tool developers.
`It is assumed that readers of this document have a working understanding of the Job Definition Format (i.e. JDF),
`the Adobe® Portable Document Format (i.e. PDF), and the PPML/VDX standard.

`A meaningful unit of information. It may be represented in various ways including as a
`file, as a part of a file, or by printed output from a job.
`Data Type Dictionary
`A hot folder is a file system directory that is monitored by a software process. Files
`placed into a hot folder are treated as input data and are processed by the software
`monitoring the hot folder. JDF uses this mechanism for file-based JDF job ticket
`submission.
`NexPress Job Queue containing jobs submitted through both the JDF Portal interface
`and Virtual Printer Hot Folders.
`The Job Definition Format (JDF) is an evolving industry standard created and
`maintained by the International Cooperation for the Integration of Processes in
`Prepress, Press, and Postpress (CIP4). JDF is an extensible, XML–based format built on
`existing technologies such as the Portable Job Ticket Format (PJTF) from Adobe® and
`on the Print Production Format (PPF) from CIP3.
`JDF provides a container for a universal electronic job ticket for all kinds of print
`production data. A JDF structure can describe both the print product to be produced
`(intent) and the steps required to produce it (processes). The NexPress front end only
`consumes JDF process.
`As defined in the JDF Specification, a JDF device interprets JDF data, identifies a
`compatible process node definition, and employs a machine that executes it
`appropriately.
`An XML data structure that specifies a print job. It may include both a print product
`description (product intent) and process definition (JDF Process). A JDF job ticket is
`comprised of one or more JDF nodes. Submission through the NexPress JDF Portal
`requires a JDF job ticket containing a single JDF process node.
`The NexPress front end’s job submission interface that conforms to the JDF
`Specification and accepts JDF job tickets either by file-based submission to a JDF Hot
`Folder, or by a SubmitQueueEntry JMF message.
`Queue containing only jobs submitted through the JDF Portal interface.

`
`Definition
`A JDF node that specifies a unit of work or a step in the job workflow. Stitching,
`DigitalPrinting, Imposition, and LayoutPreparation are examples of JDF Processes. A
`JDF Process node often specifies the unit of work to be done by a JDF Device. The
`NexPress front end only supports a single combined process node that lists all the
`required JDF processes.
`JDF elements (such as Media, MediaIntent, or Component) that are input to or output
`from a JDF process or product intent node. JDF resources are always defined as sub-
`elements of the ResourcePool. The JDF device may consume physical resources that
`are input to JDF processes (e.g., substrate described by a Media resource input to a
`digital printing process).
`-RE 0HVVDJLQJ )RUPDW ʊ -') 6SHFLILFDWLRQ “JMF is a subset of JDF that handles
`communication among JDF controllers and equipment on the shop floor…. JMF can be
`used to establish a queue, discover the capabilities of a JDF-enabled device, determine
`the status of a device, e.g., “RIPing”, “Idle”, and so on.”
`A unit of work that can processed separately. A job within a printing system may be a
`part of a larger job from the perspective of a print shop. JDF specifies what needs to be
`produced in a job and how it is to be accomplished. Typically, a job consists of work
`done on one or more files, using a set of resources, to produce output.
`A data resource managed by the NexPress front end that contains a profile entry for
`each substrate, or medium, supported by this NexPress digital production color press.
`Each profile entry describes physical characteristics of a supported medium, and the
`medium name.

`Rendering, Screening, and DigitalPrinting. Beginning with Release 10.1, only
`DigitalPrinting is required in JDF/@Types, other parameters will use default settings if
`not specified.

`Definition
`Portable Digital Master version 2.01 – an early draft of what is now the fully balloted
`and accredited ANSI CGATS.20-2002 PPML/VDX standard. This is the optimized
`Structured Document Format used by earlier versions of the NexPress front end for
`representing the page content of a VDP job. Like PPML/VDX, this also is a PDF-based
`format that contains PPML data and is used to encode the many Recipient Instances of
`a VDP job in a highly optimized way. PDM support by the NexPress front end will be
`deprecated in the future.

`the NexPress digital production color press. PDM is closely related to this standard.
`Like PDM, it is PDF-based and uses PPML data to describe Recipient Instances and
