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.
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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 130, Graphic technology.

Introduction
Packaging brand owners and procurement teams are experts in their products and are often not
experts in printing technology. This document is intended to be used as a tool to develop global and
technically consistent requirements by, for example, certification bodies certifying packaging, national
certification groups, trade associations, or brand owners to communicate their expectations throughout
the supply chain.
This document recognizes a set of best practices and International Standards related to packaging
printing. This document points to those International Standards to align requirements defined
inside schemes used in certification programs. See the Bibliography for the list of these International
Standards. Packaging and packaging graphics have a significant influence on the consumer buying
decision. The packaging printing industry is made up of a large supply chain with many workflows,
which produce a variety of printed products.
To ensure tone and colour reproduction quality, many ISO TC 130 standards specify the aims and
tolerances that are necessary for the implementation of colour-managed workflows. Even though
technical standards specify aims and tolerances, the printer’s ability to demonstrate conformity of his
production workflow to these standards is both a technical issue and a conformity assessment issue.
The packaging printing industry has unique technical and conformity assessment requirements that
are common to its stakeholders.
Certification schemes are developed by certification bodies, such as national certification groups, trade
associations, or brand owners, to address market needs. They are regional, workflow-dependent, and
with varying technical requirements. This document provides technical and conformity assessment
to allow that the various certifications are based on common principles and are comparable. As such,
this document enables the individual organizations to more readily agree to mutual recognition of the
certifications of other bodies as well as enable international trade organizations to identify comparable
competencies on a worldwide basis.
This document provides a framework for typical packaging printing workflow, either using CMYK,
CMYK with spot colour, non-CMYK, spot colour only, and multi-colour printing. It also provides a
corpus of International Standards, including aims, tolerances, and test methods, applicable at each
stage of packaging printing workflow. In addition, supply chain communication guidelines and process-
dependent checklists are also included in this document.
This document is also intended to aid the following stakeholders in understanding packaging printing
conformity assessment at an international level.
— Print buyers and brand owners
— Printing associations
— Printing organizations
— Printing production personnel
— Printing equipment manufacturers and suppliers
— Printing professionals, including auditors, consultants, etc.
TECHNICAL SPECIFICATION ISO/TS 19303-1:2020(E)
Graphic technology — Guidelines for schema writers —
Part 1:
Packaging printing
1 Scope
This document provides recommended guidelines for the evaluation of colour reproduction capability
in the printing of packaging materials. It provides a basis for the development of colour certification
schemes by individual brand owners and/or industry associations and for the evaluation of printed
results against those schemes.
Because the package printing supply chain involves multiple partners, both the potential impact of each
partner on the overall colour control and the individual responsibilities of each partner are identified in
this document. The unique requirements of the individual reproduction processes and their impact on
colour reproduction are also identified.
