This framed limited edition print is an excellent example of how artwork can become damaged due to a combination of factors. The framer has adhesive mounted the print to MDF board and has adhesive mounted the regular mat boards on top. The customer has displayed the item in a room on an outside wall of an older style home.
So what should the framer have done to help prevent this damage which has almost destroyed the print. (Scroll down to see the restored image).
The framer should have recommended that the limited edition print be framed to a minimum standard of Framing Category 4 - Conservation. This category is the starting level for items such as limited edition prints. The framing structure would have consisted of mats, an undermount and a foam core backing board. (Refer to pfgsa standard for full detail.) The print should have been hinged to the undermount.
MDF board should only be used for short term display. Ideally framers should use foam core board where ever possible. MDF board has a high affinity for moisture and mould just loves to grow in this medium.
Framers should advise their customers of environmental conditions that may affect the artwork.
What is MDF board?
"MDF is a uniform density panel having a fine, smooth surface that is ideal for shaping and routing. MDF may be easily painted, cut, machined and cleanly drilled without splintering or chipping.
MDF is an engineered waste-wood product. Manufactured from fine pine fibre that is compacted together with a resin, the surface of MDF is free of knots and grains that can make finishing difficult.
Standard MDF can be used for a variety of applications such as shelving, partitioning, paneling and furniture manufacturing."

The Restored Image A paper conservator was employed to remove the print from the MDF backing board and to treat the paper to kill and remove mould and any residue. The processes of removing the print and cleaning resulted in some minor damage to the centre area which has been touched up by the conservator. Cost of the print restoration was $99 |
