Colour variations in graffiti-proofed ceramic materials
The investigation analyses the variation of superficial properties, COLOUR and LUMINOSITY, hat the ceramic support protected by the incorporation of a protection with transparent painting undergoes, antigraffiti. The test pieces were analysed by digital procedures, obtaining quantifiable values of each ceramic sample by means of computer programs (modifications of colour) taking itself as it bases the same type of ceramics without protection. In the surface of the pieces ceramics dealt with painting antigraffiti, tones different from the original ones were observed from the piece without painting. The type of painting and the material of base, obtaining itself the following results, determine this variation: - The rustic ceramics is much more susceptible to modify its characteristics of colour that the industrialists. - In both types of analysed industrial ceramics in the investigation, the variation of the tone independently took place with the same characteristics or parameters of quantification of the type of painting. - In all the analysed types of ceramics dealt with painting antigraffiti, the colour modifies its tonality tending towards the called tones «cold», violates, by the presence of blue and the loss of the red one. Before a same painting, it was observed a greater alteration of tones and luminosity in the rustic ceramics in comparison with the industrialists.
