Backing boards for paintings on canvas [electronic resource] / [by Debra Daly Hartin ; revised by Debra Daly Hartin and staff of the Fine Arts Laboratory]. Rev. 2016. [Ottawa] : Canadian Conservation Institute, c2016. 11 p. : ill. (some col.) Canadian Conservation Institute (CCI) notes, 1928-1455 ; 10/10 Issued also in French under title: Dos protecteurs pour les peintures sur toile. Cover title. "Originally published in 1993"--p. 2. Includes bibliographical references. "All paintings should have backing boards as a preventive conservation measure. Installing a sealed backing board on an auxiliary support (stretcher or strainer) will: protect the painting from mechanical damage (e.g. puncture and tear) from behind; prevent dirt and debris from falling between the lower bar of the auxiliary support and the canvas; buffer fluctuations in relative humidity (RH) by enclosing the back of the painting (e.g. reduce the risk of cracking caused by RH fluctuations [day–night cycles] and by low RH conditions); decrease the painting’s response to shock (e.g. reduce the risk of cracking if the painting is dropped); reduce the vibration of the canvas in transit; block airborne pollutants that can damage and thus weaken canvas supports; and discourage the practice of attaching labels to, or writing on, the back of the canvas"--Introd., p. 3. gccst Art works gccst Painting gccst Conservation Canada.
