TL;DR
- An automatic press creates capacity — capacity is only money when demand exists or headcount actually changes.
- Payback is driven by sellable output and cash-effective labour, not by theoretical hours saved.
- Below roughly 8,000–10,000 impressions per month, automation usually fails on cash grounds alone.
Vendor calculations multiply hours saved by an hourly rate and present the product as savings. If the operator stays on payroll and the additional output is not sold, none of that money exists. The honest calculation separates released time from cash.
Who is this for?
Manual shops running 6,000+ impressions a month who are considering their first automatic press or an oval.
The two legitimate benefit paths
- Cash-effective labour: overtime removed, temporary staff not booked, an open position not filled, or a genuine headcount reduction.
- Sellable output: additional impressions that are actually invoiced, valued at contribution margin — never at revenue.
Benefit = Labour_cash_saved + (Extra_sold_units × Contribution_margin) − ΔEnergy − ΔMaintenance
- Labour_cash_saved = only overtime, temp staff and real headcount change
- Contribution margin = price − variable cost (never revenue)
- ΔEnergy and ΔMaintenance are usually higher after automation
Advantages
- Cycle time per impression drops 3–6×, and stays stable across a shift.
- Registration and print quality become repeatable and person-independent.
- Long runs stop blocking the shop; setup discipline becomes the constraint.
Disadvantages
- Fixed cost rises immediately: financing, floor space, compressed air, maintenance contracts.
- Setup becomes a larger share of total time — short runs may get worse, not better.
- Skill dependency shifts from printing to setup and registration.
Typical mistakes
- Monetising released hours that never leave the payroll.
- Valuing extra capacity at sales price rather than contribution margin.
- Forgetting the dryer: an automatic press feeding a manual dryer just moves the bottleneck.
- Ignoring compressed air, exhaust and floor reinforcement in the investment figure.
Manual to automatic, 14,000 impressions / month
- Investment incl. installation
- €96,000
- Overtime removed
- €2,150 / month
- Extra sold output at margin
- €4,400 / month
- Additional energy + maintenance
- −€720 / month
- Cash benefit
- €5,830 / month
- Simple payback
- ≈ 16.5 months
The same shop without the extra sold output pays back in about 45 months — the demand assumption is the decision, not the machine.
