Creating PDF brochure for printing: Remove white margin

Hi guys,

I created a brochure in Idesign which has a black background color.

In order to print the brochure I want to create a PDF (with the right order of pages, e.g. page 1 next to page 8, 2 next to 7 etc.) via the "print function".

The page order is not a problem, but unfotunately I always get a white margin although there is no such in the original indesign document.

(When using the normal "export function" of Indesign there is no white margin, but then I cannot create a PDF with the right page order for printing...)

Has anyone an idea how to solve this?

Thanks for your help in advance!

Best,

Chris
