Title: Multicoloured Jacquard artworks reproduction with CMYK channels to improve colour accuracy

Abstract

Multi-coloured Jacquard design reproduction has been restricted by the current setting of weaving machinery and therefore, varied weaving methods have been introduced to resolve the current restrictions. The CMYK (cyan, magenta, yellow and black) colour system applied to colour printing has been one of the important methods for the optical yarn colour mixing of Jacquard colour creation as a large scope of weave colour production is feasible with using only a small number of weft threads. In this study, the cyan, magenta, and yellow colour channels have been used to classify individual primary and secondary colours of the CMYK system to improve the colour accuracy of Jacquard artworks. The main principle is to combine a pair of the primary colour layers on defining a set of rules in order to segment cyan (C), blue (B), magenta (M), black (K), red (R), yellow (Y) and green (G) colours respectively. Shaded weave structures are aligned with the colour patterns to produce varied shades of weave colours. As a result, new six colour channels are created to improve Jacquard colour accuracy. This study explains the details of the C, M, and Y colour channel modification process to produce the six colour channels and weaving experiment results that examine the significance of the newly developed C, M, Y, R, G, B and K colour channels for the reproduction of multicoloured Jacquard designs.
