COLORIMETRIC PROBLEMS IN TEXTILE DESIGN SYSTEMS USING CRT DISPLAYS.

The use of digital computers in the design and manufacture (CAD/CAM) of textiles and textile products is increasing at an astounding rate. At the last Annual World Conference of the Textile Institute in Hong Kong, eight of the forty-seven papers dealt with computer assisted design of textile patterns and weaves. Part of this design process includes the simulation of the color appearance of the fabric weave and pattern. There are some commercial systems available for this and some custom systems have also been developed. While this form of color simulation (additive mixture) pre-dates even the CIE system of colorimetric specification, there are several problems which are consistently overlooked or ignored in using a CRT screen for color appearance simulation. This paper attempts to identify most of the difficult areas and reports on some efforts to develop procedures for correction of some of these problems. The discussion will be limited to the basic colorimetry of CRT displays, both instrumental and visual, as applied to textile design systems. Based on the results that will be presented, recommendations for areas of additional work will be identified, and the need for advanced colorimetry will be demonstrated. [ABSTRACT FROM AUTHOR]
