In the past historical paintings have sometimes been painted over by other artists. The motives for this procedure were different: Some artists could notafford new canvases. But also, old paintings have often been painted over in order to produce fakes on chronological authentic canvas. Due to the different composition of the old and the new colours, x-ray technology makes it possible to find out, whether there is an older painting behind the visible one. As paintings are in general much bigger than x-ray films, the x-raying of paintings with conventional methods means considerable effort. This effort can be reduced to a minimum by the use of NTB's x-ray cameras.
To x-ray paintings and sculptures we specially developed the
ART X-RAY system. For more information click here: www.artxray.com
