EN 61966-7-1:2006

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

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

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.

This European Standard was approved by CENELEC on 2006-07-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in two official versions (English and German). A version in any other language
made by translation under the responsibility of a CENELEC member into its own language and notified to the
Central Secretariat has the same status as the official versions.

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 Nati
