calender is a series of hard pressure rollers used to finish or smooth a sheet of material such as paper, textiles, or plastics. Calender rolls are also used to form some types of plastic films and to apply coatings.[1] Some calender rolls are heated or cooled as needed.[2] Calenders are sometimes mis-spelled calendars.
This printing method, used in newspapers or information paper, is a very old method, replaced by electric printers.
