Plate Cost Amortization at 72% percent of plate cost charged to this run: a worked example

Suppose percent of plate cost charged to this run falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the plate tooling cost a job carries from CTP imaging, utilization, and proofing.

The inputs for this scenario

  • Number of printing plates on the job: 6 plates (held at the documented default)
  • Cost to image one plate: 38 $/plate (held at the documented default)
  • Percent of plate cost charged to this run: 72 % (the input this scenario stresses; the baseline uses 100)
  • Proofing and color-match charge: 120 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total plate cost = plates x imaging cost/plate x utilization% + proofing charge.
  • Total plate cost amortization cost works out to 284 $ at these inputs, and this is the headline figure for the scenario.
  • Plate cost amortization cost per unit works out to 47.36 $ / piece at these inputs.
  • Variable plate cost amortization cost works out to 164 $ at these inputs.
  • Fixed plate cost amortization adder works out to 120 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where percent of plate cost charged to this run sits at 100% and the headline result is 348 $, this scenario comes in 18.34% below the baseline at 284 $.
  • Computes total plate-related cost by combining plate count, imaging cost, a utilization percentage, and a fixed proofing charge, then divides to give cost per plate. 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

  • Total plate cost amortization cost: 284 $ (headline result)
  • Plate cost amortization cost per unit: 47.36 $ / piece
  • Variable plate cost amortization cost: 164 $
  • Fixed plate cost amortization adder: 120 $
