OEE for Printing Presses: How to Measure What Presses Really Produce
OEE for printing presses measures what a press really produces: the share of its planned time that delivers good, sellable print at full speed. It multiplies three factors: availability (time actually running), performance (speed against rated speed) and quality (good output against everything printed). Measured honestly, it often shows presses producing well below what the estimate assumed — and where the time goes.
- OEE = availability × performance × quality; each factor shows a different kind of loss.
- Make-ready, stops, slow running and waste sheets all quietly cut what a press produces.
- Measure OEE by press, shift and job — not as one plant-wide average.
- Feed real OEE back into estimates so quotes reflect what presses actually achieve.
What is OEE on a printing press?
OEE stands for overall equipment effectiveness. It answers one question: of the time a press was planned to run, how much produced good print at full speed? Availability is the share of planned time the press actually ran, after make-ready (set-up between jobs), breakdowns and waits. Performance is actual speed against rated speed. Quality is good sheets or metres against everything printed.
Multiply the three to get OEE.
Illustrative example.
How to calculate press OEE
Take a press planned for eight hours. If 1.6 hours go on make-ready and stops, availability is 80%. If it then runs at 80% of rated speed, performance is 80%. If 8% of output is waste, quality is 92%. OEE is 0.80 × 0.80 × 0.92, or about 59%.
Each factor looks acceptable alone. Together, they show roughly two-fifths of the press’s potential lost.
How to start measuring OEE on your presses
Process- 01
Define planned time
Agree what counts as planned press time, so breaks and unstaffed shifts are treated consistently.
- 02
Capture stops and reasons
Record every stop with a reason: make-ready, waiting for plates, breakdown, no operator.
- 03
Record speed and waste
Log actual running speed and good versus waste output for every job, not just every shift.
- 04
Calculate by press and job
Work out availability, performance and quality separately to see which loss is biggest.
- 05
Feed actuals back
Update estimating speeds, waste allowances and schedule times with what presses really achieve.

Why the estimate and the actual never match
Estimates usually assume book speeds and standard waste allowances. Presses rarely hit them on every job: a tricky substrate (the material being printed) runs slower, a new operator takes longer to reach colour, a short run carries the same make-ready as a long one. Without OEE measured by job, nobody sees the gap, and the next quote repeats the same optimistic assumptions — margin leaks job after job.
Closing the gap with live press data
Manual logs are often filled in at the end of a shift from memory, so short stops and slow running vanish. Capturing speeds, stops and waste directly from the press gives an honest picture by press, shift and job. Owllys feeds those actuals back into estimating and scheduling, so the next quote and the next plan reflect what the press really did.
Questions people ask
What is a good OEE for a printing press?
There is no single target, because job mix matters: a press running many short jobs will always lose more time to make-ready than one running long runs. The most useful benchmark is your own trend. Measure honestly, find the biggest loss, fix it and watch the number rise month on month.
Should make-ready count against press availability?
Yes, in most cases. Make-ready is planned, but it is still time when the press is not producing sellable print. Counting it shows the true cost of short runs and frequent changeovers. Some shops also report it separately, so they can track make-ready improvements on their own.
Can OEE be measured on older presses?
Usually, yes. Where a press has no digital output, simple sensors can detect running speed and stops, and operators can add stop reasons and waste counts on a tablet. The data does not need to be perfect on day one; it needs to be honest and consistent.
