Abstract [en]

In a modern printing plant software systems are ubiquitous and indispensable. Systems for order management, production planning, and other administrative systems are implemented in software. Most, if not all, equipment on the plant floor has a software front-end that either controls the physical equipment directly or displays instructions for a human operator to interpret and execute. These software systems are not isolated islands. During production they need to communicate and exchange information. For example, a prepress workflow system may send configuration parameters to production equipment and production equipment may send status updates to production monitoring systems. This type of communication is typically implemented by sending messages, discrete units of data, between the systems. Integrating heterogeneous systems using messaging is nothing unique to the printing industry. It is a well-proven solution and there are several general-purpose solutions available for integrating disparate systems using messaging. The experience and knowledge on the subject has been documented in several pattern languages. This paper examines Job Definition Format’s messaging protocol Job Messaging Format (JMF), and maps JMF concepts to patterns found in pattern languages for system integration using messaging. Weaknesses found in JMF are discussed and patterns are applied to suggest alternative solutions. The result is JMF expressed using general enterprise integration patterns.

Abstract [en]

The print production workflow consists of various disparate systems — from production equipment to management information systems. During the production of a printed product, information regarding the product must be communicated between the systems in the workflow. Job Definition Format (JDF) is an industry standard that specifies this information interchange. It specifies a digital job ticket format for exchanging administrative and technical information related to a print job, and a messaging protocol for communicating information between the systems in the workflow. This licentiate thesis explores different aspects of integrating systems in a JDF-enabled print production workflow.

Paper III and Paper IV analyze the properties of JDF’s messaging protocol—Job Messaging Format (JMF)—and discuss design solutions for a JMF integration layer.

Paper I presents a software tool for simulating systems in the print production workflow. The tool is based on an open source software library, called the Elk Framework, which has been developed within the framework of these licentiate studies. The Elk Framework provides the base services required by a piece of JDF-enabled production equipment, called a Device/Worker in JDF parlance.

Paper II presents a software tool that was developed for testing the simulation tool presented in Paper I. The test tool, named Alces, can be used for testing if JDF-enabled systems conform to the JDF Specification.
