Abstract
The elements of the drawing can be divided into materials (paper, pencils, pens, inks, fixatives, etc.) and formal (morphological: point, line, plane, texture, light / color and shape; dynamic: tension and rhythm; and scalars: dimension, format, scale and proportion). On the material elements there are numerous studies in the field of restoration. The same is not the case with the formal elements applied to reintegration that are the object of this study.
