Use the Print Overage Calculator
Understanding Your Results
The Print Overage Calculator result is an estimating aid for the production question shown above. Interpret the output on the same quantity and waste basis used for the job ticket. Keep makeready, running spoilage, finishing loss and customer overage separate when checking the production plan.
How to Use This Calculator
- Gather the job values for Ordered quantity and Overage %.
- Keep good quantity, makeready, spoilage and customer overage on clearly separated bases.
- Select Calculate and interpret the output for Print Overage Calculator.
- Check the output against the intended imposition, finishing route and production allowance before releasing the job.
Formula & Methodology
Overage quantity = ceiling(ordered quantity × overage percentage).
Assumptions & Limitations
Use practical sheet yield and a waste basis that does not count the same loss twice. Makeready, running spoilage, finishing loss and customer overage are different quantities.
Worked Example
For a 20,000-piece order with 2% customer overage, extra good quantity = ceil(20,000 × 0.02) = 400 pieces.
Common Mistakes
Customer overage represents additional good pieces, not waste. Do not use the overage field to compensate for an unknown spoilage rate.
Frequently Asked Questions
Which inputs have the biggest effect on the Print Overage Calculator?
Overage quantity = ceiling(ordered quantity × overage percentage). The variables named in that relationship are the first values to verify when the result changes unexpectedly.
How should I check this estimate before production?
Customer overage represents additional good pieces, not waste. Do not use the overage field to compensate for an unknown spoilage rate. Compare the estimate with one completed job using the same units and quantity basis before turning a recurring variance into a shop standard.
What does the Print Overage Calculator result represent?
Calculate extra good copies required when a customer overage percentage is part of the order. The displayed methodology explains the calculation basis; use the worked example to check that your units and quantity basis match the job.
What should I verify before using this result for production?
Use practical sheet yield and a waste basis that does not count the same loss twice. Makeready, running spoilage, finishing loss and customer overage are different quantities. Confirm the entered measurements against the job ticket, equipment limits or supplier data that apply to your plant.
How should I validate the Print Overage Calculator on a repeat job?
Close the job using good quantity, makeready sheets, running spoilage, finishing loss and actual run time as separate values. Recalculate on the same basis before changing a production standard.
