Adobe PDF presets
A PDF preset is a group of settings that affect the process of creating a PDF. These settings are designed to balance file
size with quality, depending on how the PDF will be used. Most predefined presets are shared across Adobe Creative
Suite components, including InDesign, Illustrator, Photoshop, and Acrobat. You can also create and share custom
presets for your unique output requirements.
A few of the presets listed below are not available until you move them—as needed—from the Extras folder (where
they are installed by default) to the Settings folder. Typically, the Extras and Settings folders are found in (Windows
Vista) ProgramData\Adobe\AdobePDF, (Windows XP) Documents and Settings\All Users\Application
Data\Adobe\Adobe PDF, or (Mac
OS) Library/Application Support/Adobe PDF. Some presets are not available in
some Creative Suite components.
The custom settings are found in (Windows XP) Documents and Settings/[username]/Application
Data/Adobe/Adobe PDF/Settings, (Windows Vista) Users/[username]/AppData/Roaming/Adobe/Adobe
PDF/Settings, or (Mac OS) Users/[username]/Library/Application Support/Adobe/Adobe PDF/Settings.
Review your PDF settings periodically. The settings do not automatically revert to the default settings. Applications
and utilities that create PDFs use the last set of PDF settings defined or selected.
High Quality Print Creates PDFs for quality printing on desktop printers and proofing devices. This preset uses PDF
1.4 (Windows) or PDF 1.6 (Mac OS), downsamples color and grayscale images to 300 ppi and monochrome images to
1200 ppi, embeds subsets of all fonts, leaves color unchanged, and does not flatten transparency (for file types capable
of transparency). These PDFs can be opened in Acrobat 5.0 and Acrobat Reader 5.0 and later. In InDesign, this preset
also creates tagged PDFs.
Illustrator Default (Illustrator only) Creates a PDF in which all Illustrator data is preserved. PDFs created with this
preset can be reopened in Illustrator without any loss of data.
Oversized Pages (Acrobat only) Creates PDFs suitable for viewing and printing of engineering drawings larger than
200 x 200 inches. These PDFs can be opened in Acrobat and Reader 7.0 and later.
PDF/A-1b: 2005 (CMYK and RGB) (Acrobat only) Used for long-term preservation (archival) of electronic documents.
PDF/A-1b uses PDF 1.4 and converts all colors to either CMYK or RGB, depending on which standard you choose.
These PDFs can be opened in Acrobat and Reader versions 5.0 and later.
PDF/X-1a (2001 and 2003) PDF/X-1a requires all fonts to be embedded, the appropriate marks and bleeds to be
specified, and color to appear as CMYK, spot colors, or both. Compliant files must contain information describing the
printing condition for which they are prepared. PDF files created with PDF/X-1a compliance can be opened in Acrobat
4.0 and Acrobat Reader 4.0 and later.
PDF/X-1a uses PDF 1.3, downsamples color and grayscale images to 300 ppi and monochrome images to 1200 ppi,
embeds subsets of all fonts, creates untagged PDFs, and flattens transparency using the High Resolution setting.
Note: The PDF/X1-a:2003 and PDF/X-3 (2003) presets are placed on your computer during installation but are not
available until you move them from the Extras folder to the Settings folder.
PDF/X-4 (2008) In Acrobat 8, this preset is called PDF/X-4 DRAFT to reflect the draft state of the ISO specification at
Acrobat ship time. This preset is based on PDF 1.4, which includes support for live transparency. PDF/X-4 has the
same color management and International Color Consortium (ICC) color specifications as PDF/X-3. You can create
PDF/X-4-compliant files directly with Creative Suite 3 components (Illustrator, InDesign, and Photoshop). In Acrobat
8, use the Preflight feature to convert PDFs to PDF/X-4 DRAFT.
PDF files created with PDF/X-4 compliance can be opened in Acrobat 7.0 and Reader 7.0 and later.
Press Quality Creates PDF files for high-quality print production (for example, for digital printing or for separations
to an imagesetter or platesetter), but does not create files that are PDF/X-compliant. In this case, the quality of the
