ISO/IEC JTC 1/SC 28/WG 5 - Office Colour

This document provides background information and guidelines for the development of an ontology for office equipment. An example of how such a standard can be used to automate the identification of resources for colour is provided. NOTE Often the terms vocabulary and ontology are used with the same meaning.

ISO/IEC TR 21565:2018 provides an overview of office viewing environment and colour characterization guidelines for use with office equipment, in particular colour printing devices that have digital imaging capabilities, including multi-function devices.

ISO/IEC TR 29186:2012 is a supplement to CIE 156:2004, applicable for use in evaluating the colour gamut mapping algorithms of office colour softcopy and hardcopy equipment. ISO/IEC TR 29186:2012 defines test charts, test chart image processing workflow, media, viewing conditions, measurements, colour spaces and experimental methods, suitable for use with office equipment, which either do not exist in CIE 156:2004 or are different from CIE 156:2004. Colour softcopy may be displayed on monitors, incorporating display technologies such as CRT and LCD. Colour hardcopy may be produced by non-impact colour printers, including technologies such as ink jet and electro photography.

ISO/IEC TR 19797:2004 measures output and by the linearization method (LM).There is a table of output values and a graph for the first and linearized output. This method produces a linear relationship between the linear digital input data and the output data on a visual relative CIELAB scale for the colour primaries. The visual uniformity of overprint scales can be improved by this method. The method is applicable for systems that do not have colour management or as a linearization method for devices that could be used as a setup_state for colour management.
