Subject content

Colour and light. Mathematical evaluation of colour; standard light sources, tristimulus colour values, CIE system. Colour difference; according to CIELAB system, ISO standards. Metamerism. System of colour arrangement based on; psychological attributes of colour (Munsell, NCS etc.), colour of light and pigment (Pantone) mixing system, objectivity system (CIE, RAL), for specific areas in non-simetrical colour collections (marketing purposes), on screen 3-D colour presentation. Practical use of colour measurement. Kubelka - Munk theory. Calculation of a new recipe series and making corrections.

Aim of course

Basics for colour measurement is precise colour evaluation, it`s reproduction and determining differences of similar colour hues. In technological production processes, distribution of ready-made products and creation of fashion collections as well as values of colour differences are being classified as the most important when determining quality of certain product. Instrumental colour measurement is included in all industrial production processes; processes of textile technology, design, graphics, media etc.
