Design, synthesis and characterization of hybrid nanopigments formed by cationic organic dyes adsorbed on the surface of clay mineral hosts. The performance of this materials is evaluated in different applications as an alternative coloration technology, such as thermoplastic polymers, inks, cosmetics and textiles. Another research interest is focused in the use of natural dyes, insted of synthetic ones, as guest chromophores in this hybrid clay/dye nanopigments.
Comparative analysis of industrial colour gamuts, included the special-effect pigments (metallic, pearlescent, luoresecent) according to colour reproduction technologies (additive, sustractive, mix) and the human perceptible limits.
Colorimetric characterisation of printing devices. Development of colour models for the generation and formulation of colours in printing systems.
Spectral and colorimetric characterization of capture devices. Conversion of a capture device (scanner or camera) in an instrument of colour measurements.
Spectral and colorimetric characterization of display devices (CRT, LCD/TFT, plasma). Development of colour models for the generation and formulation of colours in displays.
Colour management. Implementation of computing applications for the colour profiles of the capture, display and printing devices to control the colour digital reproduction in Graphic Arts.
Measure and evaluation of colour in textured materials. Evaluation of colour differences by using a calibrated digital camera of different textures in the same natural stone. Applications: classification of sub-varieties of the same natural stone at different observation distances, texture design of ceramic tiles at several observation distances.
