Note:
Use the InDesign Preflight feature to ensure that image resolution and color spaces are correct, that fonts are available and can be
embedded, that graphics are up-to-date, and so on.
View your Adobe PDF export settings prior to exporting, and then adjust them as necessary. The Summary area includes a warning section
that indicates when preset settings can’t be honored.
If your artwork contains transparency (including overprints and drop shadows) and you require high-resolution output, it’s a good idea to
preview the effects of flattening using the Flattener Preview panel before saving the file.
If your artwork contains transparency, ask your prepress service provider if they want to receive flattened or unflattened PDF files. Flattening
should be done as late in the workflow as possible, preferably by the service provider. However, if your service provider wants you to flatten
transparency, submit a PDF/X-1a compliant file.
If your document will be separated, you can preview the separations and ink coverage limits using the Separations Preview panel.
Use only high-resolution images in your document.
For best results, use only CMYK images in a four-color-process job. Alternatively, you can choose to convert RGB images to CMYK in the
Export Adobe PDF dialog box (Output category).
You can exclude hidden or nonprinting layers from the exported PDF document. (See Choose which layers are printed or exported to PDF.)
For detailed information about preparing InDesign documents for high-resolution PDF output, see the

A service provider can use Acrobat 7.0 Professional and later to perform preflight checks and color separations. Subsequent versions of Acrobat
Professional contain 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 or later.
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.
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.
