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.
