Zum Ablösen von Kaschierungen, Entfernen von Wasserrändern, Quellen von Klebstoffen usw. ist in der Graphikrestaurierung der Einsatz von Feuchtigkeit auch bei sehr wasserempfindlichen Objekten oft unumgänglich. GORE-TEX, eine Neuentwicklung der Textilindustrie, ist hervorragend geeignet, Feuchtigkeit an das Objekt heranzubringen, aber unerwünschte Nässe fernzuhalten.

The purpose of this project was to find new methods to relax and flatten tracing paper supports for works of art. GORE-TEX barrier was used to achieve an even and gentle relaxation without any risk for water sensitive colours. Flattening was carried out on the suction table. This procedure allows severe undulations from tracing papers to be removed with minimal stress. Even highly water-sensitive colours are not endangered nor are the dimensions of the tracing papers enlarged.

Humidification is an essential part in the conservation of paper, parchment and photographic prints. Especially when dealing with water sensitive objects the application of moisture creates problems that are usually solved with expensive high-tech equipment like a humidification chamber. The use of moisture permeable materials for this purpose, which allow humidity to reach the object without wetting it, offers easy and inexpensive techniques for the humidification of water sensitive obje cts. These investigations into the use of moisture permeable materials for humidification led as well to the development of new techniques which allow the removal of residual adhesive, old linings and stains from water sensitive objects.
