General storage and handling instructions Keep the paper in its original packaging until required. Handle the paper with care to avoid damaging the coated surface. Avoid touching the coated surface (print side), as oils from the skin could be absorbed into the coating, which could have an adverse effect on the print quality. Handle the paper by the edges or underside. Do not expose the paper to extremes of temperature or humidity. After printing Coated inkjet papers can react to solvents, plasticisers or antioxidants, by producing a transient yellow cast. To avoid this, let the prints dry thoroughly. This is best done individually in drying racks, which allow free circulation of air. The prints should be left like this for up to 24 hours. Do not stack a number of freshly printed prints in a pile. Do not seal freshly printed material in polythene bags, in drawers, or other areas where air cannot freely circulate until the print is dry. If the dried prints are to be stored in plastic bags at any point, we recommend the use of bags that do not contain plasticisers. Certain material e.g. tapes, dry mounting film contain plasticisers, and can cause discolouration. Discolouration of coated papers is a known phenomenon, but it is only temporary and very rare, and can be permanently reversed by exposure to UV. If yellowing is experienced, exposing to daylight for a short period can permanently reverse it. Handle the print with care, as the surface is easily damaged.

Archival properties Somerset Photo and Somerset Enhanced is made from 100% cotton, to give you a sheet made with one of the purest sources of cellulose. As standard, St Cuthberts only make archival quality acid free paper. It is buffered with calcium carbonate to combat acid attack that finished prints may encounter from air pollution. Fade resistance For print longevity pigment inks are advised. This type of ink usually has far greater fade resistance than the equivalent dye based ink, making it ideal for coated inkjet papers. As with an original artwork, prints should be framed behind glass and hung away from direct sunlight. |
