tratteggio

An image reintegration method invented and developed in 1945- 50 in Istituto Centrale del Restauro and was inspired by the modern theory of conservation- restoration of Cesare Brandi. Tratteggio as well as its derivatives is a transposition of a representation to the system of vertical lines that, viewed from the distance, form the color (or pattern) that integrates the lacunae with the original. This kind of retouch rebuilds the image and makes it more legible being at the same time apparent and recognizable to the observer. The desired color should be achieved by putting successively the layers of delicate (rather than intensive) color vertical lines.[[2]]( a Florentine variant of trattteggio, developed by Ornella Casazza and Umberto Baldini. In selezione the lines may not be vertical but directed according to the image composition. Chromatic selection means finding characteristic features (the elementary colors) of the desired hue and recomposing it by creating the impression of a color that reintegrates the image. Colors in the chromatic selection are put in the layers that when superimposed one onto another work as transparent screens, forming the system of ‘filters’ that give the effect of unified color. Another Florentine derivative of tratteggio, developed by Ornella Casazza and Umberto Baldini after the flood in Florence in 1966. It was designed to treat the extensive losses in the painting Crucifixion by Cimabue that was seriously damaged in the flood. Astrazione was intended to be used in the situation when it’s not possible to reconstruct the original color. The idea is based on the thesis that there might be a general neutral color that matches to the whole image and provides reintegration and legibility of it. There are limited colors used for the realization of astrazione (primary colors and black). The lines are interweaving and form a vibrant screen of color on the background.
