Changing Impressions - Pressing and mounting

Changing Impressions: A Print Conservation Project in Focus

After treatment, prints are pressed to remove any distortions, which may have occurred during the conservation process or through careless storage or handling throughout their life. It is then good practice to have them mounted.

To press a print it is first humidified (as described under Backing Removal) and then placed between two stacks of blotting paper in either a mechanical press [24] or under weights supported on boards. The print will remain in the press for at least a week, depending on the seriousness of its creases.

Prints are best mounted after conservation. Mounting minimises further distortion, allows a print to be displayed attractively and protects it in subsequent storage. The quality of the mounting materials is important - much conservation work is necessitated by the effects of the acidic mounting card or wooden backing boards commonly used in the past.
