Coating Weight Yield at 68% target coat-weight first-pass yield: a worked example

Suppose target coat-weight first-pass yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate coating weight yield for specialty films, membranes and barrier materials using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Rolls meeting coat-weight spec: 8 count (held at the documented default)
  • Total coated rolls sampled: 250 count (held at the documented default)
  • Target coat-weight first-pass yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Coating weight yield rate = coating weight yield count ÷ total coating weight yield population × 100.
  • Coating weight yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Coating weight yield gap to target works out to 64.8 points at these inputs.
  • Coating weight yield count works out to 8 count at these inputs.
  • Total coating weight yield population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target coat-weight first-pass yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of coated rolls that met coat-weight specification and the point gap between that yield and your first-pass target. 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.
