Recently Jessica and I started working on a series of special collection items from UC Libraries’ DAAP Library. These were recent acquisitions specifically bought to be used as a teaching collection within the DAAP Library. Most items are small prints and single manuscript leaves that need to be matted for exhibition and prepared for handling during class. We have been working on these in small batches since it is a much larger collection that keeps growing.<\/p>\n\n\n\n

Most of the items we have received so far have been very straightforward matting projects, however we encountered one that was puzzling and fun to work on. We received this item: a proof print accompanied by its very heavy, copper engraving plate. The print was adhered to a paper brown envelope with no information and the copper plate was also unhoused.<\/p>\n\n\n\n

The curator of the collection wanted both items to be housed together and housed in a way that would allow students to touch the items, and also be able to use them for exhibits. \u00a0We decided that both items would be matted individually, and then housed together in a thin corrugated clamshell box. The most challenging part would be to create a matting system that was strong enough to secure the very heavy copper plate and elegant enough to be used for exhibition.<\/p>\n\n\n\n

The print itself received minor treatment, with the backing envelope being removed and the print housed in a polyester L-sleeve mounted with photo corners.<\/p>\n\n\n\n

With the engraving plate, I needed to figure out how to create a matting system that was strong enough to hold the copper plate in place, especially if used for an exhibit where it may be propped at a slight angle. After considering some options, I created a sink mat that would secure the plate halfway, and then the rest of the sink mat would be adhered to the window mat so the copper plate, resting on a polyester tray, could be pulled out of the mat easily. How would I keep the matting system closed? \u2026.with magnets, lots of magnets! For this project I used 24 rare earth magnets.<\/p>\n\n\n\n

This was a fun project to work on. After using 24 magnets and breaking a few in the process, the copper plate was securely housed in the sink mat, while also able to be propped up for exhibition and handled for teaching.<\/p>\n\n\n\n
