Creating PDFs
Last updated 1/14/2015
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 (Acrobat Pro) 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.
About PDF/X, PDF/E, and PDF/A standards
PDF/X, PDF/E, and PDF/A standards are defined by the International Organization for Standardization (ISO). PDF/X
standards apply to graphic content exchange; PDF/E standards apply to the interactive exchange of engineering
documents; PDF/A standards apply to long-term archiving of electronic documents. During PDF conversion, the file
that is being processed is checked against the specified standard. If the PDF does not meet the selected ISO standard,
you are prompted to either cancel the conversion or create a non-compliant file.
