The Use of Colour Physics in the Automation and Control of Package Dyeing

The application of colour physics to the measurement of colour differences between production lots and colour standards is the starting point for any quantitative study of the technical and economic case for automating dyeing processes. It is also of prime importance in sustaining automated processes. Its purposes are: (i) derivation of limits of accuracy that must be achieved for the successful outcome of any process (ii) assessment of the technical efficiency of a particular plant (iii) provision of basic data on the economies that can be achieved, and hence the amount of capital investment that can be justified (iv) monitoring of dyeworks performance to provide a convenient indication of the adjustments needed to obtain maximum plant performance (v) derivation of basic data for recipe prediction, and redip and redye calculations (vi) provision of a self-correcting, self-learning capability to allow a colour physics installation to be adapted automatically as circumstances and dyeing conditions change
