In the first half of 2026 the Chinese used printing equipment market reached RMB 8.23 billion, up 11.7 percent year on year and well above the 6.4 percent growth of the wider printing equipment market. With RMB 200 billion of ultra-long special government bond funding for equipment renewal now being deployed, used equipment trading should peak again in the second half. Yet standards across the trade still vary, and a careless buyer can fall into a low-price trap or a service gap. Based on research among ten active suppliers nationwide, this guide sets out five core inspection checklists.
- Mechanical accuracy: check cylinder bearing clearance and measured register accuracy against specification.
- Electrical system: verify PLC program integrity and that servo drive alarm histories have been cleared.
- Pneumatics and hydraulics: line sealing, stability of gauge readings and oil cleanliness.
- Consumables fitment: roller specifications, anilox line counts and compatibility with your ink system.
- After-sales terms: warranty period, on-site commissioning response time and spare parts lead time.
1. Mechanical accuracy: the lifeline of a used press
A printing press combines mechanical, electrical, pneumatic and hydraulic systems, and mechanical accuracy determines both print quality and service life. Always require measured radial clearance figures for cylinder bearings: new-machine standards for mainstream brands such as Heidelberg and Komori are typically 0.01 to 0.03 mm, and used equipment above 0.08 mm means severe bearing wear and expensive later replacement. At the same time, run a measured register check with a standard control strip; four-colour register error should stay within 0.05 mm.
2. Electrical system: the invisible risk
Electrical faults are the number one after-sales pain point for used presses, accounting for 47 percent of repairs. Check three things: whether the PLC program has been fully backed up, since some refurbishers erase or simplify original programs to cut costs; whether servo drive alarm histories have been cleared, as residual alarms often point to recurring faults; and whether cable identification in the electrical cabinet is legible, since messy wiring predicts difficult maintenance. Ask for a 72-hour no-load and load test report.
3. Pneumatics and hydraulics: the easily overlooked link
The pneumatic system handles sheet transport and on-off impression control, while hydraulics drive ink and dampening roller pressure adjustment. Check every pneumatic fitting for sealing and use soapy water to find leaks, and watch the fluctuation range of gauge readings during operation, which should stay within plus or minus 5 percent of rated pressure. Sample hydraulic oil for cleanliness: darkened oil or oil containing metal particles indicates serious internal wear.
4. Consumables fitment: the soft factor behind ramp-up time
About 63 percent of used equipment goes to regional printers with revenue below RMB 50 million, and their decisions focus on line compatibility rather than price alone. Confirm whether roller specifications, including hardness, diameter and covering material, match existing consumable stock; whether anilox line counts suit the target process, typically 80 to 200 lines for flexo and 150 to 400 for offset; and whether the ink system, solvent, water-based or UV, is compatible with the drying system on the press.
5. After-sales support: the real cost behind a low price
Two kinds of seller exist: middlemen without technical capability who attract customers with low prices but cannot refurbish, and capable refurbishers who are limited in number and concentrated geographically. Prioritise suppliers offering on-site installation and commissioning, operator training and extended warranty, and fix the response time: the industry average is 48 hours, while good suppliers compress it to 24. Confirm spare parts lead time as well; critical parts such as bearings and servo motors should ship within 72 hours.
Conclusion: The second half of 2026 offers both opportunity and risk. Use the five checklists as your yardstick and choose suppliers with full-chain qualifications, 72-hour test reports and 24-hour response commitments. In the policy window for equipment renewal, disciplined buying delivers both cost reduction and capacity upgrade.
