PRINTING SPECIFICATION OF TEXTURE MAP FOR AUDITORY
PRESENTATION OF PRINTED TEXTS
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62875 has been prepared by technical area 10: Multimedia e-
publishing and e-book technologies, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.

PRINTING SPECIFICATION OF TEXTURE MAP FOR AUDITORY
PRESENTATION OF PRINTED TEXTS
1 Scope
The texture map for auditory presentation of printed texts is printed on paper or shown on
display devices. This International Standard specifies the printing quality of this texture map
on paper.
In order to ensure an interoperability of the texture map specified in IEC 62665, a printing
specification based on the quality of this International Standard should be employed.
2 Normative reference
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.
IEC 62665, Multimedia systems and equipment – Multimedia e-publishing and e-books
technologies – Texture map for auditory presentation of printed texts
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
texture map
two dimensional cell patterns which include alignment lines and a data matrix
[SOURCE: IEC 62665, 2.1, modified – Definition has been clarified.]
3.2
data matrix
two dimensional cell patterns generated from text data compression and error correction
encoding
3.3
cell
minimum square dot which constitutes a data matrix
3.4
alignment line
border line which encloses a texture map
Note 1 to entry: An alignment line consists of solid lines and tick marks. The solid lines have a cell's width and
may partially be interrupted.
Note 2 to entry: For additional information on alignment lines, see IEC 62665.
