Perforated paper provides the convenience of detachable sheets for training manuals and workbooks, or detachable replies for invoices, return remittances and announcements. 52 microperforations generate a smooth, clean edge. 3-2/3" horizontal perforations are vacuumed and pressed to ensure maximum runnability and minimal paper dust contamination. Reverse curl control ensures that the 24 lb. sheet will lie flat enabling crisp images, few paper jams, and compatibility with post processing equipment.
