1. Scope
1.1 This standard (Part 1) prescribes the minimum overs that should be added to the base (printable) quantity of paper needed for a particular job to be printed by sheetfed letterpress and offset processes.
1.2 This wastage formula should not be applied to paper below 48 gsm including tissue paper, specialty paper and air mail paper since additional wastage is justified for printing on these papers. Wastage formula for such papers could be mutually decided between the printer and the print buyer.
