Weave Interference in Vacuum Lining of Pictures

Abstract

Draws attention to changes induced by vacuum pressure in the original painting texture. The interference effect of these wavy patterns is similar to the Moire patterns obtained by superimposing half-tone screens of different line count. This is an effect of the interaction between the weaves of 2 canvases which can be suppressed by introducing a surfacing veil, an intermediate layer of a non-woven fabric composed of synthetique fibers, compressed into a sort of felt. Suggests the use of a laminate of fiber-glass for stiffness and dimensional stability, covered on both sides by polyester surfacing veils against corrosions and abrasions. Notes that some non-woven ma terials have a pattern of their own. Describes a relining method using the fiber-glass-polyester surface veil laminate. -- AATA
