Roll-To-Roll Output at 65% line efficiency: a worked example
Suppose line efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Roll-to-roll output is the effective production rate of a continuous printing line after uptime and yield losses are removed from the raw speed.
The inputs for this scenario
- Web length or units printed per run: 1,200 units (held at the documented default)
- Roll-to-roll run time: 8 hr (held at the documented default)
- Line efficiency (uptime x yield): 65 % (the input this scenario stresses; the baseline uses 90)
Working through the calculation
- The calculation starts from the formula this tool documents: Raw roll-to-roll output = completed output รท runtime.
- Effective throughput works out to 97.5 units / hr at these inputs, and this is the headline figure for the scenario.
- Raw throughput works out to 150 units / hr at these inputs.
- Efficiency works out to 65 % at these inputs.
- Runtime works out to 8 hr at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 27.78% below the baseline at 97.5 units / hr.
- It divides completed output by run time for a raw hourly rate, then multiplies by line efficiency to give the effective good output per hour. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
Results at a glance
- Effective throughput: 97.5 units / hr (headline result)
