How do you calculate printing makeready loss?

Multiply the number of changeovers by the waste cost per makeready, scale by the spoilage share, then add the fixed plate mounting charge. With 30 changeovers at $85 each, 90% spoilage, plus a $500 mounting charge, the loss is $2,795.

What is a good makeready loss per changeover?

There is no universal target, but in this example each changeover costs $93.17. Best-in-class commercial and corrugated shops drive per-makeready spoilage down with pre-register and automatic plate mounting; if yours is far above peers, batching and setup reduction are the levers.

Why is makeready such a large cost on short runs?

Makeready waste is fixed per job, so it is spread over fewer sellable sheets on short runs. The $2,295 variable spoilage here is the same whether the run is 500 or 50,000 sheets, which is why short runs bleed margin.

What is the difference between variable and fixed makeready loss?

Variable loss ($2,295 here) scales with changeovers and spoilage share and shrinks if you run fewer, longer jobs. Fixed loss ($500 here) is the plate mounting and setup charge that hits regardless of run length.

How can I reduce makeready spoilage share?

Automatic register control, pre-mounted plate sleeves, standardized ink sequences, and color-managed proofing cut the sheets wasted reaching target density. Dropping spoilage share from 90% toward 70% directly lowers the variable portion of this calculation.

Makeready loss vs run waste — what is the difference?

Makeready loss is the spoilage before good sheets run; run waste (or running spoilage) is the ongoing loss during production from web breaks, splices, or drift. This calculator isolates the makeready piece so you can attack setup separately.

Printing Makeready Loss Calculator

Makeready loss is the material and labor waste burned bringing a press up to color and register before a single sellable sheet runs. On flexo and offset lines feeding corrugated and folding-carton work, print schedulers, plant controllers, and estimators use it to see how much short-run job hopping quietly costs them. It matters because makeready is almost pure overhead: every changeover you add multiplies spoiled board, ink, and idle press time. Quantifying it per changeover is the first step to justifying gang-running, longer runs, or automated register systems.

What this calculator does

Estimates the substrate and ink spoiled during press makeready plus plate setup cost across job changeovers.
A print room lead uses it to quantify makeready waste when bidding short-run versus long-run work.
It computes the total dollar loss from press makeready across a batch of changeovers, splitting variable spoilage from the fixed plate mounting charge, plus the loss per changeover.

Formula used

Makeready loss = changeovers x waste per makeready x spoilage% + plate mounting charge
Loss per changeover = total loss / job changeovers

Inputs explained

Job Changeovers per Run:
Waste Cost per Makeready:
Spoilage Share of Makeready Sheets:
Plate Mounting and Setup Charge:

How to use the result

Use it when quoting short-run print work, comparing job-batching strategies, or building a case for makeready-reduction capital like automatic plate mounting or closed-loop register control.
It treats waste cost per makeready as an average; jobs with wide color counts or difficult substrates vary widely, so a single blended rate can understate loss on your hardest changeovers.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The producer price index for paperboard and containers stands at 276.831 (BLS, May 2026), up 8.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 13,899 wood product manufacturing establishments employing about 432,255 workers (Census County Business Patterns, 2023).
