How to export to PDF from Adobe InDesign
After the Document is checked and all the errors given after
Preflight, are corrected, the Document should be exported to print-ready PDF file.
To export the Document choose
File → Adobe PDF Presets → [PDF/X-4:2008]...
PDF/X-4:2008 standard meets our printing requirements, so no parameters need to be changed.
Please only mark
Crop Marks,
Page Information and
Use Document Bleed Settings in the
Marks and Bleeds window and set width of bleeds. We recommend to use 5 mm bleeds.
Offset must be 5 mm.

If the
Bleed setting is not set in the document settings, you will see a 0. We recommended to specify Bleed in the Document setting
3-5 mm (to change Bleed parameter in the Document settings go to
File→ Document Setup or
Ctrl + Alt + P). For hard-binding covers the Bleed value must be
18 mm:

In the
Color Conversion field choose
Convert to Destination (Preserve Numbers) and in the
Destination field select color profile by the paper you use. In the PDF/X parameters
