Studio Essentials : White Core Mount Board 60x80cm (Apx.24x31in) : Extra White

Studio Essentials White Core Mountboard is a 1.5mm-thick acid-free mountboard which weighs 850gsm. It consists of three layers: a 110gsm paper surface which is available in various colours; a 1.1mm thick, fully coated, bleached paperboard core which is acid-free and is considered sufficiently inert to be used in direct contact with documents; a backing layer of white chlorine- and acid-free cellulose paper.These mountboards are not fully lightfast and should not be stored in direct sunlight, though they will display good colour stability if stored out of direct sunlight. The front surface paper and the white paperboard core accord with ISO 6588, while the back paper accords with ISO 9706. It is the back sheet, which is most fully in contact with the artwork, that has the highest archival specifications.Studio Essentials White Core Mountboards are available in 60 x 80cm sheets in a selection of classic colours.
