Opacity optimisation for paint topcoat/undercoat combination

摘要

An opacity optimisation system (100) selects a suitable undercoat base colour and determines the optimal tint for the undercoat to have the best reflectance properties for a chosen topcoat colour, e.g. to tint a white coloured undercoat with different levels of grey or black to achieve the desired reflectance properties. The system (100) includes one or more input devices (102,104) to receive input colour data, a processing system (106) and an output device (108) including a visual display unit and a printer. The processing system (106) includes an opacity optimisation module (110) and a database (112). The opacity optimisation module (110) generates paint colour data (114), full hiding colour data (116), colour combination data (118), colour difference data (120), con-elation data (122), selector data (124), background colour data (126), and undercoat colour difference data (128).
