What is this BS EN 61966-7-1 - Colour measurement and management about?
BS EN 61966-7-1 discusses multimedia systems and equipment and colour measurement and management with a focus on colour printers, reflective prints, and RGB inputs. BS EN 61966-7-1 is the seventh part of the multi-series on BS EN 61966 multimedia systems and equipment 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.
BS EN 61966-7-1 is applicable to the characterization of colour printers that produce colour on opaque substrate corresponding to digital data files in which colour image information is expressed in a red–green–blue colour space. The characterization will be realized by objective measurements to be utilized for colour management in open systems. The measured and reported results are used to relate the equipment-dependent and undefined red–green–blue colour space to the default RGB colour space defined as the sRGB by IEC 61966-2-1. BS EN 61966-7-1 is also applicable to the assessment of colour image attributes on reflective prints reproduced from colour digital image files.
Note: BS EN 61966-7-1 does not specify limiting values for various attributes.
Who is BS EN 61966-7-1 - Colour measurement and management for?
BS EN 61966-7-1 on colour measurement and management is useful for:
- Television manufacturers
- HDR technology developers
- Research and development personnel
- Design engineers
Why should you use BS EN 61966-7-1 - Colour measurement and management?
A series of methods and parameters for colour measurements and management for use in multimedia systems and equipment applies to the assessment of colour production and reproduction. BS EN 61966-7-1 deals with equipment using colour printers, reflective prints, and RGB inputs. for use in multimedia applications.
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 a reflective substrate. BS EN 61966-7-1 provides methods of measurement that 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.
What’s changed since the last update?
BS EN 61966-7-1:2006 supersedes EN 61966-5:2001, which is withdrawn. BS EN 61966-7-1:2006 includes some technical change with respect to EN 61966-5:2001.
These include:
- 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: a short-term instability test chart and spatial non-uniformity test chart were added
