Waste percentages on a Digital press are based off of the total number of press sheets. On an Offset press, it is based off of press sheets per pass. 

  • Press Sheets Up To - Used to set breaks
  • Flat Overs - A flat number of overs
  • Percent - Overs based on the quantity of sheets


When calculating waste, the scale does not slide. The Waste calculation is the percentage of Total Number of Press Sheets plus a Flat Number of Sheets.

  • Exact matches use the listed percentage and flat sheets
  • If the Quantity exceeds the maximum Quantity in the scale, the maximum Quantity is used.
  • If the Quantity is below the minimum Quantity, the minimum Quantity is used.
  • If the Quantity is between scales, the next highest scale is used.
  • Example: 


    Press Sheets Up ToFlat OversPercentage Overs
    500110.00
    999999402.00



    If the number of Press Sheets = 350, the calculation would find the first Waste Scale and the calculation for overs would be:

    Percentage Overs + Flat Overs = Total Overs

    35 (10% of 350 Press Sheets) + 1 (Flat Overs) = 36

     

If the number of Press Sheets = 1000, the calculation would find the second scale because the number of Press Sheet has exceeded the Press Sheets up to the first scale.

Percentage Overs + Flat Overs = Total Overs

20 (2% of 1000 Press Sheets) + 40 (Flat Overs) = 60
