IDD (and IDML) (Adobe InDesign)
Layout program from Adobe

InDesign is a layout program that is mainly used to create advertising materials such as flyers, posters, brochures and for typesetting magazines or books. INDD files can only be opened and edited in InDesign, but PSD and AI files can be used there without any problems. Print files are exported from InDesign as PDF.

The IDML format is selected for forwarding IDD files. The file is then saved so that it can also be opened in older versions of In Design.

MISSION: Flyers, brochures, posters, magazines, books
