<\/a> \u00a0\nWe have been experimenting with a fancy new vacuum packer, generally used for food preservation. We are using it to flatten books and other paper items. It would be inefficient for batch work because of all the material that needs to be cut to size but for especially warped books it is very effective.\u00a0<\/p>\n
We cut blotter pieces, card, and book board all to size.\u00a0 All of the interleaving material must be cut to the size of the book so that the edges don’t interfere with the sealing of the bag. The inside of the book is lightly misted, and the blotter sheets placed inside.\u00a0 The book is sandwiched between pieces of blotter, card, and book board.\u00a0 Rubber bands hold the stack together. The stack is then placed inside a special plastic bag.\u00a0<\/p>\n

During this process the moisture from the pages is drawn into the dry blotter between the pages. The pages, which were relaxed by the moisture, are drawn flat by the pressure. We generally leave a book in the sealed bag overnight. Ideally, we open it the next day and the book is perfectly flat.<\/p>\n","protected":false},"excerpt":{"rendered":"
