Full Description

This document provides guidance on methods for computing and communicating colour gamuts for output colour reproduction systems such as printers and displays. Different methods for defining a colour gamut boundary are reported. A procedure for describing the colour gamut of a reproduction system is explained. A step-by-step method for calculating the volume of colour gamut is provided along with the colour gamut metrics for comparing two colour gamuts.

The document describes methods for visualization of a 3D colour gamut surface. A set of information required for reporting a colour gamut has been developed. Different methods of encoding a colour gamut boundary description are mentioned. Examples for the CxF-based encoding of colour gamut boundary descriptors are provided as electronic attachments to this document.

The publication is written in English, with a short summary in French and German. It consists of 22 pages with 7 figures and is readily available from the CIE Webshop or from the National Committees of the CIE.

Full Description

Upper air ultraviolet germicidal irradiation (UVGI), in combination with appropriate room ventilation, is increasingly being used as a method to reduce transmission of airborne
infectious diseases such as tuberculosis. UVGI luminaires appropriate for upper room air disinfection are installed above eye level and designed to limit vertical emission spread in order to prevent exposure to occupants as much as possible. Accurate UVGI luminaire emission profiles are needed to calculate the dose required for disinfection of airborne microorganisms. A radiometric measurement protocol for UVGI luminaires is a basis for this method of measurement. This guide is intended to promote uniformity and accuracy in the measurement of UVGI luminaires. Data will be exportable to any standard electronic data file formats for use in lighting softwar e programs adapted for UVGI application.

The publication is written in English, with a short summary in French and German. It consists of 28 pages with 4 figures and is readily available from the CIE Webshop or from
the National Committees of the CIE.
