Standard (Acrobat only) 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, but also embeds subsets of all (allowed)
fonts used in the file, converts all colors to sRGB, and prints to a medium resolution. Note that Windows font subsets are not embedded by default.

About PDF/X and PDF/A standards
PDF/X and PDF/A standards are defined by the International Organization for Standardization (ISO). PDF/X standards apply to graphic content
exchange; 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 will not meet the selected ISO standard, a message appears, asking you to choose between
canceling the conversion or going ahead with the creation of a noncompliant file.
The most widely used standards for a print publishing workflow are several PDF/X formats: PDF/X - 1a, PDF/X - 3, and (in 2007) PDF/X - 4. The most
widely used standards for PDF archiving are PDF/A
-
1a, and PDF/A
-
1b (for less stringent requirements).
Note: For more information on PDF/X and PDF/A, see the ISO website and the Adobe website .
PDF compatibility levels
When you create PDFs, you need to decide which PDF version to use. You can change the PDF version by switching to a different preset or
choosing a compatibility option when you save as PDF or edit a PDF preset.
Generally speaking, unless there’s a specific need for backward compatibility, you should use the most recent version (in this case version 1.7).
The latest version will include all the newest features and functionality. However, if you’re creating documents that will be distributed widely,
consider choosing Acrobat 5.0 (PDF 1.4) or Acrobat 6.0 (PDF 1.5) to ensure that all users can view and print the document.
The following table compares some of the functionality in PDFs created using the different compatibility settings.
Note: Acrobat 8.0 and 9.0 also use PDF 1.7.
Acrobat 3.0 (PDF 1.3) Acrobat 5.0 (PDF 1.4) Acrobat 6.0 (PDF 1.5) Acrobat 7.0 (PDF 1.6) and
Acrobat X (PDF 1.7)
