Colour management of a low-cost four-colour ink-jet printing system on textiles

A low-cost four-colour (RBYK) dye-based ink-jet printing system for textiles was introduced in this study, in which red and blue inks were employed instead of the magenta and cyan inks used in half-tone printing. The basis of a colour-management system for this device was developed by determining the mapping between XYZ tristimulus values of output colours and the digital RBYK values using polynomial transforms. A second-order equation was found to give the best performance with an average characterisation error of under 7 CIELAB units.
