Graphic technology — Communication of offset ink properties

This document specifies offset ink related properties which are intended to be communicated between ink supplier and the printer, and which are essential for the optimized print production planning and the intended use of the final product. NOTE The final product is not necessarily the finished print product. Aspects related to food safety and other safety requirements like children's toys safety are not part of the scope of this document.

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

Introduction
Offset printing inks are special purpose, complex mixtures of chemicals intended to be applied on a
substrate by offset printing. They have customized properties and defined drying mechanisms resulting
in ink films with standard or customized properties. This document establishes requirements on the
communication of offset ink properties, aiming to the optimized planning of printing and to ensure the
inks have the appropriate properties for the intended use of the printed products. Examples are the
use of alkali resistant inks for combined use with dispersion varnishes to avoid colour changes after
printing or the use of higher light fast inks for outdoor applications.
For the printing of food packaging, additional requirements are in continuing development. Often,
these are related to the usability of particular substances within the inks. Printers of food packaging
are recommended to stay in close contact to their ink suppliers and industry federations and to follow
actual developments in this are
