Second-hand printing equipment carries high unit prices and long delivery chains. A typical used four-color offset press for half-size format (e.g., 40×56 cm) transacts between RMB 400,000 and 1.5 million. Most disputes do not arise from the equipment itself, but from gray areas in the contract terms. Incorporating the following 8 clauses into the contract allows the buyer to maintain control at key stages such as acceptance inspection, payment, quality disputes, and cross-border logistics.
Equipment identity clause: Model, year of manufacture, serial number, and a photo of the original nameplate must correspond one-to-one. Condition disclosure clause: Total impression count and replacement records of critical wear parts must be provided in writing. Payment schedule clause: Deposit, inspection payment, and final payment are released in three stages to avoid paying the full amount at once. Trial printing acceptance clause: The contract must specify the number of trial sheets, trial printing items, and the deadline for rectification of non-conformities. Warranty scope clause: Clearly state the warranty period for core components, response time, and spare parts supply channels. Logistics and installation clause: Responsibilities and cost allocation for dismantling, transport, positioning, and commissioning must be defined. Intellectual property clause: The seller must provide a written commitment on the legality of computers, control software, and licenses. Dispute resolution clause: The competent court or arbitration institution must be agreed upon in advance to avoid the cost of cross-regional litigation.
I. Equipment Identity and Condition Disclosure: Rejecting "Same Model, Different Machine"
Two used Heidelberg CD102 presses of the same model can differ in residual value by more than 20% due to differences in operating environment, maintenance standards, and printed product mix. The contract must specify the machine nameplate number, control system version, a photo of the factory nameplate, and the total impression count and key maintenance records over the past three years. Once this information is written into the contract in black and white, the burden of proof in the event of "goods not matching the description" is minimized.
II. Payment Schedule: Three-Stage Release Is the Safest Approach
Industry practice is 30% deposit + 60% inspection-acceptance payment + 10% warranty retention. The inspection-acceptance payment should be made only after the buyer has completed on-site trial printing and met the acceptance criteria. Never release payment based solely on a video inspection. The 10% warranty retention is recommended to be held for 3–6 months to cover quality issues discovered after delivery.
III. Trial Printing Acceptance: The Contract Must Define "Rejection Criteria"
This is the stage where disputes most frequently occur. It is recommended that the contract specify the trial printing items: full-coverage solid, 50% screen tint, fine text, four-color registration accuracy, etc. Each item should have a quantifiable threshold (e.g., registration error ≤ 0.05 mm), and the seller's rectification deadline and responsibility for round-trip costs in the event of non-conformity must be agreed upon.
IV. Warranty and Spare Parts: Core Component Protection Period of No Less Than 6 Months
For core components such as circuit boards, servo motors, cylinder bearings, and air pumps, a warranty period of 6–12 months is recommended, and the seller should be required to provide a list of common spare parts and supply channels. For cross-border purchases, confirm in advance whether after-sales engineers can reach the site, to avoid the predicament of "equipment breaks down with no one to repair it."
Conclusion: The core risk in second-hand printing press transactions lies not in machine selection, but in the contract. By clearly defining equipment identity, condition disclosure, payment schedule, trial printing rejection criteria, warranty scope, and dispute jurisdiction in advance, the buyer can truly hold the initiative when disputes arise.
