Printing, Labels & Industrial Converting worked example

Proofing Workload with proofs demanded per day of 250 units: a worked example

This scenario runs the proofing workload calculation on the strong side: proofs demanded per day of 250 units, with every other input held at its documented default. Use it when proofing workload in printing, labels and industrial converting is being sized against an asset rating.

The inputs for this scenario

  • Proofs demanded per day: 250 units (raised for this scenario; the documented default is 100)
  • Proofing throughput factor: 1.2 x (unchanged)
  • Shift runtime: 8 hr (unchanged)

Working through the calculation

  • Applying the documented formula (Required proofing workload load = proofing workload demand รท proofing workload utilization target) to the inputs above produces each figure below.
  • At this operating point the engine returns 300 hr for total load, the number this scenario is built around.
  • At this operating point the engine returns 37.5 hr / hr for hourly equivalent.
  • At this operating point the engine returns 250 hr for input load.
  • At this operating point the engine returns 1.2 x for load factor.

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 150% above the baseline at 300 hr.
  • Use it during daily or weekly prepress scheduling to check whether incoming proof volume fits your staffed shift before you commit due dates. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total load: 300 hr (headline result)
  • Hourly equivalent: 37.5 hr / hr
  • Input load: 250 hr
  • Load factor: 1.2 x
