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).

Introduction
Standards are documented consensus agreements containing safety, technical specifications, or
other precise criteria to be used consistently as rules, guidelines, or definitions of characteristics for
materials, products, processes, and services. In many cases, they provide uniformity, which allows
worldwide acceptance and application of a product or material. The aim is to facilitate trade, exchange,
and technology transfer. Standards help to remove technical barriers to trade leading to new markets
and economic growth for the industry.
Today, companies are facing fundamental changes in the way they do business. Strategies and business
practices are continuously being evaluated to determine how to maintain and increase market share,
reduce costs, increase productivity and safety, and achieve and maintain a competitive edge.
Graphic arts companies face these changes starting from a point at which the standards are not
completely adopted by the market even if they provide complete technical guidelines. Graphic
industries are only a small part of the graphic market made up of micro and small handcraft companies
throughout the world. During recent years, many transformations have occurred in the market. Digital
communications and digital media technology have driven restructuring in the graphic arts industry.
ISO/TC 130 is working to reflect these changes in the standard development structure with new
approaches and ideas to follow today’s market and trends and anticipate future requirements.
All graphic arts companies can use the structure of the published standards to support their business
and to harmonize production workflows irrespective of the size of the company. Published standards
for the printing, publishing, and finishing industries enable processes to run faster, more predictably
and more efficiently, and to be more cost effective by
— providing uniform, defined procedures, and tools that help users produce quality products for
their customers,
— facilitating interconnectivity and process integration among systems,
— allowing users to communicate easily with one another,
— enhancing product quality and reliability at a reasonable price,
— increasing distribution efficiency and ease of maintenance,
— improving health, safety, and environmental protection, and
— reducing waste.
The language used to write standards in recent decades mainly reflects the needs of printers and the
printers’ suppliers, ignoring the other actors in the printing supply chain. This Technical Report tries to
describe the relationship between standards with all the actors in the graphic supply chain taken into
account, preparing the market for tomorrow’s standards structure.
The composition of the graphic arts supply chain varies depending on the kind of product manufactured
and the size of the graphics project measured in terms of the number of copies, but tends to be similar
around the world. Every actor or stakeholder in the supply chain may be a single person, a small
company, or a big organization. In every case, thanks to the digitalization of the graphic arts supply
chain achieved mainly over the past 20 years, instruments, methodology, and production standards can
be the same irrespective of the size of the stakeholder’s organization. Today, a single freelance designer
can use the same software and provide the same results as a gigantic multi-national agency and there is
no technical reason why they should not use the same standards. The same is true for printers. A small
printing company with the ability to produce at the same quality level can compete or collaborate with
big companies if both follow the ISO standards. .
All the ISO/TC 130 standards, particularly the process control standards, aim to describe the so-called
“standard quality”. Many people in the graphic arts industry think that this “standard quality” is good
for big production companies distributed worldwide, but not for small regional production companies.

---------------------- Page: 5 ----------------------
ISO/TR 19300:2015(E)

This was not the intention of ISO/TC 130 because if the “standard quality” reflects the minimum set of
warranties that a supplier needs to give to customers, in terms of fulfilling the expectation of a small
variability within printing runs, most of the companies that ignore ISO standards have big problems
in maintaining a constant level of predictable quality of the final results. Without such predictability,
the result is likely to change in every printing run and the final product will be a unique handcrafted
printed product, which in most cases, is unlikely to fulfill the needs of customers in any scenario.
The set of parameters used to define the print quality attributes of a final graphic product have not
been described in any document up to now, but ISO/TC 130 is working with other ISO committees
to define such a set. ISO/TC 130 standards describe and define certain parameters for a printing
product, together with their tolerances, but ignore most of them. Since most ISO standards are related
to properties of materials and to process control, the quality is here defined by parameters related
to single and unfinished print. Within ISO aims and tolerances, there is the possibility of delivering
different products so that small companies making regional products can benefit from standardization
and produce something both unique and precious. At the same time, big companies can follow ISO aims
and tolerances strictly to guarantee predictability and consistency around the world. Quality control
of the final product is not, in most cases, standardized so finishing processes such as lamination,
varnishes, and binding, which affect customer satisfaction, will depend on the ability of printers,
finishers, or converters.
Digital printing is more and more widely used in graphic arts production and its processes interrelate
and overlap with traditional printing. There are many different fast-changing digital printing
technologies and it is now included in many conventional printing companies. We can consider a
printing process as digital either when the image is transferred to the substrate by a digital technology
and there is no printing form or when the process has the ability to change the image with every print.
Digital printing influences workflows and process control. International Standards that support digital
printing are under development within ISO/TC 130, for instance, the ISO 15311 (all parts). Other ISO
documents can be used in a digital printing workflow, for instance, the ISO PAS 15339 (all parts).

4 Base concepts
ISO standards for graphic arts and the related workflows described in this Clause imply some basic
concepts that have significantly evolved over the recent years. The intended audience for these concepts,
as described in the actual ISO standards, is mainly technical. The summary provided would be an index
of arguments and references.

ISO/TR 19300:2015(E)

4.1 Viewing conditions
While colour measurements play an important role in the control of colour reproduction, they cannot
replace the human observer for final assessment of the quality of complex images. Paper and other
substrates contribute to the perceived colours and controlling these is equally critical.
ISO 3664:2009 contains all the necessary specifications and information about viewing conditions for
critical and practical comparison of printed samples such as reference illuminant, illuminance level,
colour rendering index, and other parameters that should be used by all stakeholders to assess the
lighting environment of working places.
An important update in ISO 3664:2009 includes a better specification of the light in the ultraviolet
(UV) and visible spectrum range to avoid distorting the appearance of samples in comparison with the
appearance under commonly used sources of illumination such as daylight. The UV content is important
where fluorescent samples are encountered, a phenomenon associated with many of the paper
substrates on which images are reproduced as well as with some of the dyes and pigments themselves.
The new measurement conditions described in 3.2 are defined with reference to this aim and specify
tolerances that provide consistency between visual judgment and colour measurement.
4.2 Colour measurements
To assess the quality of a coloured printed product and to control the process, all the standards refer to
colour aims and tolerances. It is not expected that measured colorimetric data will provide an absolute
correlation with visual colour appearance, although recent improvements in lighting equipment and
measurement instrument technology provide stakeholders with a good level of correlation if all the
standards are applied.
ISO 13655:2009 contains all the necessary specifications for spectral measurements and colorimetric
computation, and even if these are intended for use by instrument and systems suppliers, it is very
important that the base concepts are clear to all stakeholders so as to achieve conformity in the
equipment and methods used.
The four measurement conditions (M0, M1, M2, and M3) may provide different spectral values and
colorimetric interpretations (CIELAB) for the same sample depending on the degree to which they
fluoresce. It is very important that the stakeholders agree on which kind of condition is to be used to
exchange data, adding information about the backing that can be extrapolated from process standards.
Condition M0 refers to all spectrophotometers or densitometers compliant with old versions of
ISO 13655 or optimized with density measurements according to ISO 5-3. If there is a lack of information
about colour measurements, M0 should be assumed.
Condition M1 defines UV content more accurately and makes it possible to minimize variations in
measurement results between instruments due to fluorescence (arising from optical brighteners in the
substrate and/or fluorescence of the printing and/or proofing colorants). Condition M1 also improves
the consistency between measurement results and visual assessment in viewing booths that meets the
requirements of ISO 3664:2009.
Condition M2 was previously called “UV-cut” and is adopted when the fluorescence needs to be excluded
from the measurements. The effect is that there is poor consistency with visual assessment. However,
M2 is still used to make characterizations in some digital printing environments where proofing is not
commonly used.
Condition M3 refers to polarized densitometers which are used for process control, especially in sheet-
fed offset printing. Even if it is possible to manage spectral or colorimetric M3 data, there is no practical
application in any process standard.
4.3 Printing condition
A printing condition is defined by a set of primary process parameters that have a direct bearing on the
visual appearance of a printed product. For every printing process, specific parameters are defined that
© ISO 2015 – All rights reserved 5

---------------------- Page: 11 ----------------------
ISO/TR 19300:2015(E)

contribute to summarizing the printing condition as described in the appropriate part of ISO 12647.
These parameters include, for example, the colour and gloss of the paper substrate, the colour of the
process inks, the screening adopted, and the curves specifying the tonal value increase. A complete
explanation of the printing condition can be found in ISO 12647-1.
4.4 Characterization
When a printing condition is established through a process standard, it is then possible to measure a
colour characterization that describes the colour reproduction capability of the process, including the
colour of the substrate and the description of the colour gamut. Characterization data comprise a set of
tone values and associated colorimetric values that fully describe a given printing process. Where such a
set of colour characterization data are used as a reference in workflows, it is referred to as a characterized
reference printing condition (CRPC) as described in the ISO PAS 15339 (all parts) documents.
Depending on the chosen workflow, to ensure the consistency of colour reproduction from the design
stage to the print stage, it is very important for digital artwork that correct communication of the
characterization is ensured. A characterization may be referred to by a commonly used name maintained
by an association or organization (e.g. FOGRA39 or GRACoL_2006) and either the colorimetric files
exchanged as defined in ISO 12642 or ICC output profiles exchanged as defined in ISO 15076-1.
4.5 Grey reproduction and grey balance
Reproduction of neutral grey colours is an important topic in every CMYK printing process because it
affects the overall visual appearance of the printed product and facilitates process control. A neutral
grey colour composed of specific CMY tone values is one of the most difficult colours to reproduce in a
print
