Comparing screen and device resolution in placed PDF pages
A placed PDF page displays at the best resolution possible for the given scale and screen resolution. When printed on
a PostScript output device, a placed PDF page always prints at the resolution of the device. When printed on a non-
PostScript printer, a placed PDF page prints at the same resolution as the other InDesign objects in the document. For
example, vector (drawn) objects will print at the same resolution as other vector objects in the document. Bitmap
images will print at the best resolution supplied in the placed PDF.
Linking to placed PDFs
A placed PDF page appears in the InDesign document as an on-screen preview, which is linked to a specific page in
the original PDF. After placing a PDF page, you may break links by doing any of the following:
• If you add a password to the original PDF that has been placed in an InDesign document, and you update the link,
you’ll be prompted to enter the password.
• If you delete pages in the original PDF and update the link, the placed PDF page changes to the page that now falls
on the originally placed page number.
• If you reorder the pages in the original PDF file and update the link, the placed PDF page may be different from
what you expect. When that happens, place the page again.
Color in placed PDF pages
InDesign preserves colors embedded in PDF pages, even if the color comes from a color library not installed with
InDesign (such as the PANTONE Hexachrome® library). In addition, any color traps included in a placed PDF page
are preserved.
When color management is active, InDesign displays the placed PDF using its embedded ICC or output intent profile
(PDF/X only). When color management is turned off, or when you place a PDF that doesn’t contain an ICC or output
intent profile, colors in the placed PDF are calibrated using the color profile in the InDesign document.
When you export or print the document, you can preserve the ICC profile embedded in the placed PDF or replace it
with the document profile instead. Output intent profiles are used for display and are included when you export as
PDF/X; they aren’t used when you print the document, and they aren’t included when you export to any other format.
Security settings in placed PDF pages
Because a placed PDF page is linked to the original PDF, the placed page also includes the security settings of the
original file. If someone later changes the security settings in the original file, the security settings are updated in the
placed PDF page when you update the links.
If you correctly enter a required master password when placing a PDF page, you override any restrictions in the PDF
page, enabling the placed PDF page to export as expected.

Importing InDesign (.indd) pages
Using the Place command, you can import pages from one InDesign document into another. You can import a page,
a page range, or all of the pages in the document. The pages are imported as objects (much the same way that PDFs are
imported).
