A paper object may be lined to a secondary support for a variety of reasons that include the repair of damage such as extensive tears, or to reinforce and strengthen an object that is fragile and brittle. When Polyester encapsulation is not practical or suitable, lining to a secondary support material can impart strength evenly over the object, and may be the most effective option for securely integrating the object. Any tissue lining will affect the clarity of the text and images on the lined side of the object. This study investigates a variety of different lining materials and techniques in current practice to determine the most transparent method possible. Mock objects were lined to thin Japanese tissue and Lens tissue with wheat starch paste, methylcellulose, hydroxypropyl methylcellulose and combinations of the above. Different methods of pressing and drying were employed. Heat set tissues and fine polyester support fabrics were also tested. The results were assessed visually and with a densitometer to compare the transparency of the tissue lining, and the clarity of text and image on the tissue side.
