- JDF stands for Job Definition Format. A simple way to look at JDF is to consider it as a type of job ticket. JDF is XML-based; it provides a single common language that supports the life cycle of a print job.
- JMF stands for Job Messaging Format. It defines the communication mechanism to send JDF files and receive JDF answers. It is a full part of the standard itself.
Together, JDF/JMF is a widely used standard in the printing industry, bringing interoperability to software applications across all aspects of a print production environment.
