IEC 61966-7-1:2006

Multimedia systems and equipment - Colour measurement and management - Part 7-1: Colour printers - Reflective prints - RGB inputs

IEC 61966-7-1:2006 specifies a set of data in colour test chart files for measurements, sampling of successive prints, measurement conditions and forms of reporting the results so as to make possible the characterization of the colour printer and comparison of the results of measurements. The sets of data for measurements are in colour test chart files expressed in a red-green-blue colour space, to which corresponding colour images are reproduced on reflective substrate. The methods of measurement in this standard are designed to be applicable to reflective colour prints for consumer use. The reflective colour prints may be produced by non-impact colour printers, incorporating such technologies as ink-jet, sublimation transfer, thermal transfer, electro-photography and other similar technologies. This second edition cancels and replaces the first edition published in 2001 and constitutes a technical revision. It includes the following significant technical changes: In addition to the default illuminant, D50, D65, F11 and illuminant. A were added as optional illuminants. The numbering of the colour patches in the test-chart file was changed for easy understanding of the measurement location. Two test-chart files: short-term instability test chart and spatial non-uniformity test chart were added. This bilingual version (2012-08) corresponds to the monolingual English version, published in 2006-05.

Systèmes et appareils multimédia - Mesure et gestion de la couleur - Partie 7-1: Imprimantes couleur - Imprimés à réflexion - Entrées RVB

La CEI 61966:2006 spécifie un jeu de données dans les fichiers de mire couleur pour les mesures, l'échantillonnage d'imprimés successifs, les conditions de mesure et les formulaires de retour des résultats, de façon à permettre la caractérisation de l'imprimante couleur et la comparaison des résultats de mesure. Les ensembles de données pour les mesures se trouvent dans des fichiers de mire couleur exprimés dans un espace chromatique rouge-vert-bleu, où des images couleurs correspondantes sont reproduites sur un substrat réfléchissant. Les méthodes de mesure de cette norme sont conçues de manière à pouvoir s'appliquer à des imprimés couleur à réflexion pour usage grand public. Les imprimés couleur à réflexion peuvent être produits par des imprimantes couleur sans impact, incluant des technologies telles que le jet d'encre, le transfert par sublimation, le transfert thermique, l'électrophotographie et d'autres technologies similaires. Cette deuxième édition annule et remplace la première édition parue en 2001. Elle constitue une révision technique. Elle contient les modifications techniques significatives suivantes: En plus de l'illuminant par défaut, D50, D65, F11 et l'illuminant A ont été ajoutés comme illuminants facultatifs. La numérotation des motifs de couleurs dans le fichier de mire a été modifiée pour comprendre facilement l'emplacement de mesure. Deux fichiers de mire: mire d'instabilité à court terme et mire de non-uniformité spatiale ont été ajoutés. La présente version bilingue (2012-08) correspond à la version anglaise monolingue publiée en 2006-05.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61966-7-1 has been prepared by Task Area 2: Colour
measurement and management, of IEC technical committee 100: Audio, video and multimedia
systems and equipment.
This second edition cancels and replaces the first edition published in 2001. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition.
a) In addition to the default illuminant, D50, D65, F11 and illuminant A were added as
optional illuminants.
b) The numbering of the colour patches in the test-chart file was changed for easy
understanding of the measurement location.
