Graphic technology - Prepress digital data exchange using PDF - Part 8: Partial exchange of printing data using PDF 1.6 (PDF/X-5)
ISO 15930-8:2010 specifies the use of the Portable Document Format (PDF) Version 1.6 for the dissemination of digital data intended for print, whereby all elements necessary for final print reproduction are either included or provision is made for unique identification of externally supplied graphical content or n‑colorant ICC profiles.
Colour-managed, CMYK, gray, RGB or spot colour data are supported in any combination; as are PDF transparency and optional content. Files can be prepared for use with gray, RGB, CMYK and n-colorant printing characterizations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Introduction
ISO 15930 (all parts) defines methods for the exchange of digital data within the graphic arts industry and for
the exchange of files between graphic arts establishments. It is a multi-part document where each part is
intended to respond to different workflow requirements. These workflows differ in the degree of flexibility
required. However, increasing flexibility can lead to the possibility of uncertainty or error. The goal throughout
the various parts of ISO 15930 has been to maintain the degree of flexibility required while minimizing the
uncertainty.
Many printed documents are assemblies of partial pages and/or pages created at different locations and by
different organizations. The merging of these individual elements into the final printing form and the
subsequent printing can take place at different locations. Some of these elements might also be routed to
multiple sites for incorporation into other documents. Each of these elements is referred to in ISO 15930 as a
compound entity.
A variety of data formats and structures are used for the creation of this type of material, but with two
prevalent kinds of underlying data structures. These are vector-based data for the encoding of line art and
textual information and raster-based data for the encoding of image information, including previously
rasterized line art and textual information.
Both kinds of data structures are required along with page description information in an open electronic
workflow. The exchange of raster-based data using the TIFF/IT file format is defined in ISO 12639. The
subject of ISO 15930 is a format for the exchange of object-based data where individual objects can be in
either vector or raster data structures.
The various parts of ISO 15930 define a number of conformance levels intended to address different
requirements; all define data formats and their usage to permit the predictable dissemination of a compound
entity to one or more locations. These goals are accomplished by defining a specific use of the publicly
available Adobe Portable Document Format (PDF). In order to achieve a level of exchange that avoids any
ambiguity in interpretation of the file, a limited set of PDF objects that are permitted to be used is identified
and restrictions to the use, or form of use, of those objects, and/or keys within those objects are added.
In some environments, the data exchange needs to be in a form ready for final print reproduction, by transfer
of a single file. This file contains all the content information necessary to process and render the document, as
intended by the sender, coded inside a single PDF file. No other files, neither external files nor internally
embedded files, are required or permitted. This exchange requires no prior knowledge of the sending and
receiving environments and is sometimes referred to as “complete” or “blind” exchange. It is
platform-independent and transport-independent. Whereas many production workflows benefit from the
exchange of complete material, with all elements present, there are circumstances when this is not
appropriate. In certain workflows, some or all of the referenced elements might be more logically present at
the receiving site, or might be exchanged at a different time. These include high-resolution contone-image
files, line-art files, ICC profiles, etc. These exchanges will generally require prior agreement between sender
and receiver.
In some environments the exchange has to be restricted to CMYK (and spot colour) data, whilst in others it is
more appropriate to convey it as colour-managed, CMYK, gray, RGB, and/or spot colour, or to use alternative
process colour models.
Several new versions of the PDF specification have been issued since the publication of ISO 15930-1 in 2001.
More recent parts of ISO 15930 expand on and extend earlier parts by reference to later versions of the PDF
specification.
Table 1 summarizes the conformance levels defined in the various parts of ISO 15930.

predictable dissemination of a compound entity to one or more locations, as colour-managed data, CMYK
data, and/or spot colour data, by transfer of a file with some elements not included, but with provision for
unique identification. An exchange identified by this part of ISO 15930 might require communication between
sender and receiver to select the mechanism by which elements not included can be identified.

This part of ISO 15930 specifies PDF/X-5 conformance levels, which can be seen as expansions and
extensions of the PDF/X-4 and PDF/X-4p conformance levels defined in ISO 15930-7, in that it allows the use
of an n-colorant print characterization, and allows some data necessary for final printing to be supplied
externally to the main file being exchanged, as follows.
⎯ PDF/X-4 requires all raster and vector data to be imaged on the final print to be included within the single
file being exchanged; PDF/X-5 allows such data to be held in external files.
This allows the use of workflows similar to those using Open Prepress Interchange (OPI) comments in
PostScript, or OPI objects in baseline PDF. These can have value in reducing the demands on design
applications and the computers that they are used on, by allowing designers to work with low-resolution
versions of images. They also enable parallel processing of work on an image or other graphic, and the
page onto which it will be placed. In a publication or newsprint workflow, they allow advertising and
editorial submissions to be composited together late in the workflow, without requiring that files submitted
by third parties be amended in any way before the final prepress processes.
