In the Standards pane, you can do the following:
•
Click Verify Conformance to evaluate the le. If the Status is listed as
“verication succeeded,” you know the le complies with the standard
and the listed OutputIntent.
•
Click Check Prole Fingerprint to be sure the audit trail matches the
listed prole.
•
Click Remove Preight Audit Trail to delete the content, which you
may want to do if you are the nal recipient of a le.
#40: Ensuring Standards Compliance
Apples and Oranges
Are Different
Don’t expect to be able
to convert any file to a
standards-compliant file
simply because you can
choose a profile that will
convert the file. Sometimes
there simply aren’t enough
pieces of document informa-
tion or metadata to allow for
the conversion. For example,
if you have a file converted
from a Word document that
used online settings, you
won’t be able to convert
that smoothly into a PDF/X
file compliant with print
standards.
The solution? If possible,
return to the source program
and reproduce the PDF file
using the standard you need.
If you don’t have the source
file, you may get the result
you want using a couple of
profiles.
Variations on a Theme
You can choose from a number of PDF print standards. The one you select
depends on the final processing of the document:
•
All PDF/X standards are designed for graphics exchange. The files must con-
tain specific page content and resources.
•
All compliance options contain an OutputIntent and a printing profile.
•
A document destined for digital press uses a PDF/X-1a standard; this stand-
ard has versions for 2001 and 2003.
•
Choose PDF/X-3 standards that are 2002- or 2003-compliant; the PDF/X-3
standard includes color usage options—CMYK and spot colors only or cali-
brated color.
•
PDF/X-4 prepress digital data standards based on PDF 1.6 as either com-
plete exchange of printing data (PDF/X-4) or partial exchange with an exter-
nal profile reference (PDF/X-4p).
•
PDF/X-5, also based on PDF 1.6, offers three levels based on graphical con-
tent and ICC profiles.
•
Specific named standards such as Sheetfed Offset (CMYK) are based on best
practice guidelines recommended by industry associations.
Use the PDF/A standard for documents intended for long-term storage in PDF
format. The file can’t include external players, external links, or protection in
order to ensure viewing and printing over the long term. PDF/A standard has
two variations—1a and 1b.
The PDF/E standard is designed for engineering PDF document exchange. PDF/E
files can contain 3D models and annotations. However, the content and resources
must be embedded in the file to guarantee reliable viewing and printing.
