Printing, Labels & Industrial Converting worked example

Proofing Workload with proofs demanded per day of 50 units: a worked example

This worked example runs the proofing workload numbers for a tougher week than the baseline: proofs demanded per day of 50 units instead of the typical 100 units. Estimate proofing workload for printing, labels and industrial converting using production-ready inputs so teams can compare demand with available capacity and identify overload risk.

The inputs for this scenario

  • Proofs demanded per day: 50 units (the input this scenario stresses; the baseline uses 100)
  • Proofing throughput factor: 1.2 x (held at the documented default)
  • Shift runtime: 8 hr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Required proofing workload load = proofing workload demand รท proofing workload utilization target.
  • Total load works out to 60 hr at these inputs, and this is the headline figure for the scenario.
  • Hourly equivalent works out to 7.5 hr / hr at these inputs.
  • Input load works out to 50 hr at these inputs.
  • Load factor works out to 1.2 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where proofs demanded per day sits at 100 units and the headline result is 120 hr, this scenario comes in 50% below the baseline at 60 hr.
  • Use it during daily or weekly prepress scheduling to check whether incoming proof volume fits your staffed shift before you commit due dates. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total load: 60 hr (headline result)
  • Hourly equivalent: 7.5 hr / hr
  • Input load: 50 hr
  • Load factor: 1.2 x
