Abstract
Over the centuries, numerous artists and forgers had painted over paintings. Some of the most common reasons were economic, discontent with the painted image, experimenting, or art forgery. More than a thousand works of art in Zagreb were analysed in the visual and near-infrared (NIR) spectrum. During analyses in both areas, artworks in seven museums, three collections, eleven museum and gallery exhibitions, five private collections and one studio in Zagreb were analysed and photographed. Thanks to the IR reflectography, in some paintings, in the layers that are invisible to the naked eye, preparatory drawings, pentimenti/displacements, fully overpainted paintings or overpainted parts of painting, hidden signatures and underpaint were revealed thus unveiling the stages of the artist's work. In art monographs, catalogues and various publications, paintings have been reproduced in black and white or colour prints. With the discovery and understanding of the InfraRedDesign, art reproductions can be printed in both spectra simultaneously. Such print with IR properties offers a new approach to reproduction as it expands the so far hidden insights regarding layers in the creation process of the original artwork. With the use of an IR camera, infrared light absorption is shown in the image reproduction.
