Sleeves are made from various materials, including thermoplastic composites, thermoset composites, and nickel, and may or may not be reinforced with fiber. So-called “thin” sleeves without foam or cushioning were developed to be thrown away after use to keep costs down. Long-run, reusable sleeves with a foam or cushion base are used for very high-quality printing. Most are currently processed in solvent chemistry processors. However, predicts Esko-Graphics’ Hole, “By the time drupa 2008 opens next year, you can expect to see a number of sleeves that are processed with thermal systems.”
