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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

This second edition of ISO/TS 15311-1 cancels and replaces the first edition (ISO/TS 15311-1:2016),

assess media relative colour reproduction with BlackPoint compensation.

Introduction
When producing a colour reproduction, it is important that the persons responsible for data creation,
colour separation, proofing and printing operations have previously agreed a minimum set of
parameters that define the visual characteristics and other technical properties of the planned print
product. This document identifies a number of metrics that can be applied to printed sheets and that
can be used as the basis for such communication. The range of metrics is large and it is not intended
that all of these metrics are to be applied to any given printed product and for any given application,
the range of metrics is to be carefully selected, for example based on subsequent parts of ISO/TS 15311.
The metrics described by this document can be applied to any type of print. They are likely most often
to be applied to digitally printed prints.
When selecting the set of metrics, only those metrics that have a clear specification and that correlate
well with human perception are included in this document. Since this is an area of significant research
activity, new metrics are expected to emerge and existing metrics to be revised in the next few years.
For this reason, we anticipate the need to revise this document within a very short time scale as new
metrics are tested and found to be reliable.
Additional tests to those specified in this document, for example visual assessment of smoothness,
images and other elements may be required when assessing print quality.
As with any parameter that is used as part of a product specification, it is important for readers to
understand clearly what the metric means. For this reason, a reporting schema is to be followed when
reporting measurements in conformance with this document.

Part 1:
Measurement methods and reporting schema
1 Scope
This document defines print quality metrics, measurement methods and reporting requirements for
printed sheets that are suitable for all classes of printed products.
Guidance as to which of these metrics to apply to any given product category along with acceptable
conformance criteria is provided in subsequent parts of ISO/TS 15311.
Although this document is expected to be used primarily to measure prints from digital printing
systems, the metrics are general and may be applied to other kinds of print.
