Developer website: vjoon GmbH

The K4 Crossmedia Publishing Platform is an award-winning editorial system for Adobe InDesign CS and Adobe InCopy CS, designed to organise the work of graphic designers and editors, as well as to control the production process. With its multilevel security controls and robust customization options, K4 supports a transparent and secure production workflow for individual workgroups or entire publishing enterprises across multiple locations.

K4 offers simultaneous workflow between layout and editorial, copy editing at the page stage, content and layout change alerting, workflow routing, status tracking, version control, galley or WYSIWYG editing mode, red lining, change tracking, inline notes and much more.

K4 manages layouts, articles, images, ads, audio/video each with their own fully customizable status workflow. In addition, Microsoft Word manuscripts, Excel spreadsheets, or any other type of file can be managed within the system, centralizing publishing content and making the system available to all participants in the process. Thus, K4 offers unprecedented flexibility for a broad range of professional publishing environments.

K4 6.1's modern workflow engine takes into account dependencies between media channels, can be individually configured and can push content to any number of output channels - web, print or mobile. The system is built on modern multi-tier architecture that supports various databases, such as MySQL, Oracle, and MS SQL. A Hamburg-based software vendor that has been in business for just under 20 years, vjoon understands the importance of connecting third-party systems quickly and provides a Web Services API (application programming interface) to this end.

Since 1999, the K4 publishing platform has been successfully deployed at magazines, newspapers and other sites ranging in size from 10 to more than 1.100 users. In total, some 17, 000 users are working on the system.
