Introduction
ISO 20616 defines standard XML schemas designed to enable the digital exchange of print quality data
and metadata between trading partners within the graphic arts supply chain. In the past, a number
of different non-standard data formats have been used to communicate print quality metrics. It is a
general observation that many of these existing non-standard data formats describe similar types of
information. Existing standard data formats cover either too much or too little scope to address industry
requirements. Hence, there is an industry need for a single, standard concise set of data formats for the
communication of print quality.
Each part of ISO 20616 is intended to stand alone, but may be used in conjunction with each other,
should that option be chosen. The goal of ISO 20616 is to maintain the degree of flexibility required by
print buyers for all ki

print buyers for all kinds of print generated for all purposes from any print device while minimizing the
uncertainty of the data exchanged.
This document is intended to facilitate the one-way transmission of performance data for one or
more printed samples, for one or more brands or products from a single press run from print service
providers to relevant stakeholders and print buyers; thus, allowing them to assess and track relevant
business, production, colour and quality data of printed materials of all forms. PQX is only intended to
transmit raw quality data. The PQX file intentionally excludes tolerance and evaluative information,
allowing the receiver to determine acceptability by applying their own scale and tolerance values. PQX
incorporates colour using the same data containers that are defined in ISO 17972-4 (CxF3_Core.xsd).
While PQX and CxF are different formats with different parsing requirements, developers can use the
