A CDE Definition
Job Definition Format
An XML-based file and message format for PDF print jobs. The job definition format (JDF) file, which is linked to the PDF file, describes the job's press requirements such as quantity, paper type and finishing. The Job Messaging Format (JMF) provides commands for communicating with devices in the PDF workflow; for example, to start and stop machines, transfer error messages and so on.
CIP3, CIP4, PPF and PJTF
JDF was developed by Adobe and printing press manufacturers Heidelberg, Agfa and MAN Roland in 1999. It was turned over to the International Cooperation for the Integration of Processes in Prepress, Press and Postpress Organization in 2000, which at the time was named CIP3. In 2001, CIP4 was formed to manage the JDF specification with roadmaps for converting job tickets in CIP3's previous Print Production Format (PPF) and Adobe's previous Portable Job Ticket Format (PJTF) into JDF. See PDF.
(Portable Document Format) The de facto standard for electronic document publishing from Adobe. There are billions of brochures, data sheets, white papers, forms and technical manuals on the Web in the PDF format.
Render, Save As and Edit
Adobe's free Acrobat Reader and many other applications can display and print PDF files. Documents can also be saved (exported) to PDF in Windows, starting with Windows 10, and the Mac, as well as with many conversion programs that convert various formats to PDF. However, although PDFs can be easily generated, editing PDFs requires Adobe Acrobat or other software that specifically features PDF editing.
PDFs Provide Font Freedom
PDFs solved a chronic problem, in which the target computer may not have all the fonts specified in a document. For a graphic artist, font selection is an important part of page design, but, in the past, only basic fonts were chosen to ensure they were available in every user's computer.
In contrast, PDF files do not rely on the fonts installed in the user's computer. Document designers are free to choose whichever fonts they have at their disposal, and those fonts are embedded within the PDF document. Because the fonts are not distributed for general use, they do not violate copyrights and patents, and most importantly, the page will render the same on every computer. See PDF/X and font incompatibility.
PDF Is a Superset of Adobe PostScript
PDF is often the preferred file format for sending documents to commercial print houses. If the commercial printer uses PDF imagesetters, no conversion is necessary. If it uses only PostScript hardware, the PDF files are converted to PostScript first. See PostScript, PDF/A, PDF/X, WWF, DjVu and XML Paper Specification.
