Canson® Conservation Backing Boards

Untextured cardboards that have been laminated together in multiple plies using neutral glue, they are easy to cut.

They are acid-free, have an alkaline buffer and comply with the ISO 9706 conservation standard, they have no optical whitener and have been treated against mould.

Our Canson® Conservation Backing Boards are available in a number of thicknesses and in 3 colours : a black, a pure white and an antique white which is particularly suited for prints, engravings and ancient documents.

Canson® Conservation is also proposed as board lined with off-white Kraft for use as a direct backing. One white side (in contact with the artwork), the other lined with (acidic) Kraft paper, the board being thick enough to act as a protection.
