Another application: A watercolor with media so sensitive to water that it couldn't be sprayed on the front, and with the problem that the picture tends to curl toward the back. The procedure followed was first to humidify the picture in a humidity chamber, then to dry it with its back against mylar to retard evaporation from the back. A porous, moisture-permeable polyester web was placed on the front to permit movement of moisture into an adjacent blotter. This arrangement tended to cause the front to dry last, since the moisture in the picture had to travel from back to front, thereby counteracting the previous curling toward the back.
