Adobe Acrobat Pro PDF print production protrusion of 3mm

[massimiliano_7976]

So I have the following question: I work on a project that is eventuelly going to a print company for printing. They want me to have specific settings for my PDF (for example CMYK colors, PDF/X-1a,...). Now, one sais they want a protrusion of 3mm. So the end format is A4 and they basically want A4 + protrusion of 3mm. Since I am a Newbie and design my Layout with Word (please dont judge me, but it is not that professional) I simply added 6mm in height and length, thinking the 3 mm would thus be ok. Now the printing company wrote that it shows them 216 * 303 (those are the said 6mm extra) and that they want, as I said, A4 + 3mm? How can I do this in Acrobat Pro?

This project is likely long gone, but better late than never if this helps someone else...

MS Word PDF files wouldn't contain the expected PDF page boxes. Your PSP is likely looking for explicitly set trim and possibly bleed boxes, if not visual marks. Using Acrobat Pro use All Tools > Use Print Production > Set Page Boxes:

Note: This was a single page example, you would need to set the page range to all on a multi-page PDF.

You can also change the Page Size (Media Box):

And also add trim or other marks using All Tools > Use Print Production > Add Printer Marks:

Note: the green and red page box visualisations will not print, they can be found under Preferences/Settings > (General) Page Display: Show art, trim & bleed boxes.
