Sažetak
We are studying inks through information of their absorption spectra. Data are measured continuously in visual and near infrared region. New color hues are achieved by different colors mixtures, but their appearance properties are respected in both spectral domains. Measured spectra of dyes are key information for identification of twins, for at least two dyes, that obtain equal spectrograms in visual, but different in near infrared region. New colors are prepared for ceramic application with “metallic-gold” ink This article presents light colors in the visual spectrum, and which have high absorption values in near infrared spectrum. Dyes with the addition of metallic gold, significantly changes the direction of research on the development of the twin colors and dyes. This paper presents innovative solutions for tints intended for creating double images, double information, creating intimate and hidden invisible artworks with colorants for ceramics. This is an advance in safety and proving the authenticity of artwork. At the exhibition, and at a conference, the visitors can observe ceramic exhibits with new developed of the dual infrared camera.
