Produce a print-ready Adobe PDF file
A service provider can use Acrobat 7.0 Professional and later to perform preflight checks and color separations.
Acrobat 8 Professional contains more advanced preflight tools, including the ability to make certain corrections
automatically. Various prepress applications and in-RIP technologies can also perform preflight checks, do trapping
and imposition, and make the color separations of the pages in the digital master.
If you choose to leave out the images when creating the Adobe PDF file, make sure that the service provider has
access to the original high-resolution images that are required for proper output. In addition, make sure that the
service provider has Acrobat 7.0 or later for accurate viewing of text and color graphics. For best viewing, they should
use Acrobat 8 Professional.
If you’re using a color-managed workflow, you can use the precision of color profiles to perform an on-screen
preview (a soft proof). You can examine how your document’s colors will look when reproduced on a particular
output device.
Note: Unless you are using a color management system (CMS) with accurately calibrated ICC profiles and are sure you
have properly calibrated your monitor, don’t rely on the on-screen appearance of colors.
1 Prepare the document for exporting to Adobe PDF.
2 Export using the .joboptions file provided by your service provider. If you don’t have a preferred .joboptions file,
use a PDF/X preset.
3 Preflight the PDF in Acrobat 7.0 Professional or later.
4 Proof and correct the PDF file.
5 Hand off the press-ready PDF to the prepress service provider.
Structuring PDFs
Adding structure to PDFs
When you export to Adobe PDF with the Create Tagged PDF option selected in the General area of the Export Adobe
PDF dialog box, the exported pages are automatically tagged with a set of structure tags that describe the content,
identifying page items such as headlines, stories, and figures. To add additional tags or to fine-tune existing ones
before you export, you can use the Tags panel in InDesign. The Structure pane (View > Structure > Show Structure)
reflects the changes.
You can improve the accessibility and reuse of Adobe PDF documents by adding tags to the InDesign document
before you export. If your PDF documents don’t contain tags, Adobe Reader or Acrobat may attempt to automatically
tag the document when the user reads or reflows it, but the results may be disappointing. If you do not get the results
you want in the exported PDF file, you can use tools in Acrobat 6.0 Professional and later to edit the structure of
tagged PDF documents. For the most advanced tools, use Acrobat 8 Professional.
