carrier sheets have been used, very effectively, for many years in the
reprographics industry. They virtually eliminate damage to original
documents as they pass through the copying or imaging equipment.
Document carriers should be used for any large document that can that is
considered irreplaceable, or for documents that are very thin or have
damage. A scanning department should always have carrier sheets on
hand, for damaged documents, they are reusable and if handled carefully,
they can last for a long time. Colortrac provides the sheets with a WHITE or BLACK background. For standard documents, the white sheet is best. If you need to scan document with printing on thin paper, with image on the back side (i.e. Newspaper), you would use the black backing. This keeps the image on the back from being captured along with the front.
Colortrac carriers are made of two sheets of acrylic
film, a clear top sheet and a white backing sheet. The two sheets are
attached along one edge. The acrylic film is very translucent, providing a superior image quality. These are the recommended carrier sheets for all Colortrac scanners.
The document is placed between
the two sheets of film and then fed through the scanner, inserting the
hinged side first. The document is safely transported through the
scanner without any damage, even if there are tears, folds, damaged
edges or holes in the original.
Carrier sheets are sometimes called document wallets.
