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

to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 130, Graphic technology.
This second edition cancels and replaces the first edition (ISO 12647-5:2001), which has been
technically revised.
ISO 12647 consists of the following parts, under the general title Graphic technology — Process control
for the manufacture of half-tone colour separations, proof and production prints:
— Part 1: Parameters and measurement methods
— Part 2: Offset lithographic processes
— Part 3: Coldset offset lithography on newsprint

Introduction
Historically, this International Standard established the process control parameters and their aim values
and tolerances for the most important professional printing processes of the graphic arts industry. The
initial concept was that the groundwork for the series was laid down in ISO 12647-1. This part of the
ISO 12647- series differs from that concept because screen printing has changed significantly since this
International Standard was initially conceived.
This edition of this part of ISO 12647 differs from the earlier edition by not defining specific printing
condition aims but instead requiring that a specific reference printing condition (characterization
data set) be specified. This part of ISO 12647 requires that the colour of the printed product match
a characterization data set or a printing condition agreed upon by the provider and the receiver
and specifies minimum requirements and tolerances to be communicated and produced. Where
specific physical parameters can impact the final result (screen angles, resolution, screen mesh, etc.),
specifications and tolerances are provided for these parameters.
Because material produced by screen printing varies widely in both size and nominal viewing distance,
a viewing distance metric is introduced as part of all screening and resolution requirements.
INTERNATIONAL STANDARD ISO 12647-5:2015(E)
Graphic technology — Process control for the manufacture of
half-tone colour separations, proof and production prints —
Part 5:
Screen printing
1 Scope
This part of ISO 12647 specifies the requirements for the screen printing of four-colour process-colour
material used for display, signage, and graphics using flat bed or cylinder printing equipment. Both the
size and resolution of the finished product are unrestricted. The process stages included are
— data preparation and delivery,
— proof production,
— printing forme preparation, and
— production printing.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12647-1 apply.
4 Requirements
4.1 Data requirements for screen printing systems
4.1.1 Data delivery
Screen print systems shall accept digital data delivered as PDF/X data files as defined in ISO 15930-1 or
TIFF/IT files as defined in ISO 12639.
The intended printing condition shall be either
1) a published Characterized Reference Printing Condition (CRPC) as listed in the ICC registry at www.
color.org, or
2) a custom data set where none of the available reference colour characterization data sets are
considered appropriate for the intended printing because of the inks, paper, or other factors.
Where the characterization data to be used have a substrate colour (CIELAB values) that does not
match the substrate to be used, the data should be adjusted using the tristimulus correction method
defined in Annex B.
Prior agreement as to the characterization data and substrate adjustment to be used shall be obtained
between all parties involved before copy preparation work is started.
Characterization data sets are the only method recognized by this part of ISO 12647 for the proper
identification of the printing condition to be used. Film and/or directly expose
