Creating PDFs
Last updated 10/11/2011
PDF/A-1b: 2005 (CMYK and RGB)
Used for long-term preservation (archival) of electronic documents. PDF/A-1b uses
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 PDF bounding boxes 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. It
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. However, they
aren’t available until you move them from the Extras folder to the Settings folder.
PDF/X-4 (2007) (Acrobat Pro)
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 applications (Illustrator, InDesign, and Photoshop). In
Acrobat 9, 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 color
separations to an imagesetter or platesetter). However, it does not create files that are PDF/X compliant. In this case,
the quality of the content is the highest consideration. The objective is to maintain all the information in a PDF
file
that a commercial printer or print service provider requires to print the document correctly. This set of options uses
PDF 1.4, converts colors to CMYK, and downsamples color and grayscale images to 300 ppi and monochrome images
to 1200 ppi. It embeds subsets of all fonts and preserves transparency (for file types capable of transparency).
These PDF files can be opened in Acrobat 5.0 and Acrobat Reader 5.0 and later.
Note:
Before creating a PDF file to send to a commercial printer or print service provider, find out what output resolution
and other settings are required. Or, ask for a .joboptions file with the recommended settings. You sometimes must
customize the Adobe PDF settings for a particular provider and then provide a .joboptions file of your own.
Rich Content PDF
Creates accessible PDF files that include tags, hyperlinks, bookmarks, interactive elements, and
layers. This set of options uses PDF 1.6 and embeds subsets of all fonts. It also optimizes files for byte serving. These
PDF files can be opened in Acrobat and Reader 7.0 and later. (The Rich Content PDF preset is in the Extras folder.)
Note:
This preset was called eBook in earlier versions of some applications.
Smallest File Size
Creates PDF files for displaying on the web or an intranet, or for distribution through an email
system. This set of options uses compression, downsampling, and a relatively low image resolution. It converts all
colors to sRGB, and (for Adobe Acrobat Distiller-based conversions) does not embed fonts. It also optimizes files for
byte serving.
These PDF files can be opened in Acrobat and Reader 6.0 and later.
Standard
Creates PDF files to be printed to desktop printers or digital copiers, published on a CD, or sent to a client
as a publishing proof. This set of options uses compression and downsampling to keep the file size down. However, it
also embeds subsets of all (allowed) fonts used in the file, converts all colors to sRGB, and prints to a medium
resolution. Windows font subsets are not embedded by default. PDF files created with this settings file can be opened
in Acrobat and Reader 6.0 and later.
