TATTOOWALL has recently found application in the field of restoration, being the only technique able to reproduce faithfully frescoes lost or damaged. It was used for the first time in the restoration of lost frescoes by Mantegna in Padua at Ovetari Chapel. It was used anastylosis informatics, a kind of mapping of the positions of the fragments through computer techniques of image recognition. With TATTOOWALL ® has completed the work through the digital method, the image was created in size with neutral shades ranging from gray to white. The faithful reproduction and real data from TATTOOWALL ® has allowed to integrate the work of the restorers.
