The Buyer’s Pallets: A Practical Framework for Client-Supplied Litho Stock
The decision to supply paper is often commercial rather than suspicious. A client may hold stock from a previous campaign, buy through a merchant account, or need a specific mill brand for consistency across a group of products. None of that is a problem for a litho printer. The problem begins when the pallets arrive and the assumptions on both sides have not been written down. Client-supplied stock changes the risk profile of a job. It does not have to change the relationship.
Agree the stock, not just the name
A paper specification for a client-supplied job needs to be more precise than a merchant’s shorthand. Record the mill, brand, grade, substance in gsm, finish, sheet size, grain direction and any relevant certification. If the job depends on bulk, stiffness or shade, say so explicitly, because two papers that carry the same gsm can behave quite differently on press and in the finished piece.
Where a substitute is acceptable, define what equivalent means in writing. It may mean the same grade and substance from another mill, or it may mean a named alternative that has already been approved on a previous run. If the printer is expected to match an existing stock, supply a sample sheet or a retained copy of the previous job. A verbal assurance that the paper is the same as last time is not a specification.
This is not about second-guessing the buyer. It is about giving the printer a fair chance to set the press correctly and to flag a mismatch before plates are made. If the supplied stock differs materially from the agreed specification, the printer should be able to reject it or re-quote the job without being cast as obstructive.
Condition belongs in the specification
Paper is hygroscopic. It takes on and gives off moisture, and it responds to temperature. A pallet that has sat in a cold, damp warehouse or travelled on an unprotected vehicle may look fine from the outside and still cause register problems, curl or inconsistent ink transfer once it reaches the press. Condition is therefore part of the specification, not an afterthought.
Agree who inspects the stock on arrival and when. The inspection should cover pallet wrap, edge damage, water staining, obvious deformation and the number of packs or reams. A short goods-in note with photographs is useful evidence if a claim is needed later. Where the job is sensitive, agree whether the printer will take moisture readings or simply allow the stock to condition in the pressroom for an agreed period before running.
Conditioning takes time. A pallet that arrives straight from a cold delivery may need to settle before it is unwrapped and used. Building that time into the schedule is cheaper than discovering the problem on press. If the client wants a just-in-time delivery, the printer should say plainly what that removes from the process.
Spoilage, make-ready and the reserve
Every litho run consumes paper before a saleable sheet appears. Make-ready, colour adjustment and normal running waste are part of the process. When the printer supplies the paper, that allowance is usually built into the estimate. When the client supplies it, the allowance has to be agreed separately.
Put a percentage or sheet count in writing and state who provides the reserve. If the client sends only the net quantity, the printer has no buffer for spoilage, and a shortfall becomes a production problem rather than a paper problem. The cost of a second delivery, a lost press slot or a part-run is rarely limited to the price of the missing sheets.
The same applies to damage caused during the run. If the printer damages stock through poor handling, the printer should own the replacement. If the stock is short from the merchant, or the client has miscounted, the client should own it. If the paper itself is defective, the position is less simple: the printer can document the fault, but the commercial claim usually sits with the party that bought the stock. Agree the principle before the job starts so that nobody has to negotiate it under deadline pressure.
Delivery timing and goods-in
Client-supplied paper often arrives from a merchant or a storage facility rather than from the printer’s own supplier. That makes the delivery window more important, not less. Confirm the booking process, the vehicle type, pallet dimensions and maximum weight. State whether a tail-lift or forklift is needed and whether the delivery point can accept pallets outside normal hours.
A delivery that blocks the loading bay or arrives after the press slot has been set is a schedule risk. The printer should not be expected to absorb demurrage, rebooking or idle press time because a third-party delivery missed its window. Equally, the client should not be asked to accept a delivery date that leaves no time for inspection and conditioning. A buffer of a few working days is usually cheaper than a compressed run.
When the stock fails on press
Not every paper fault is visible at goods-in. Picking, hickeys, delamination, curl and inconsistent shade can appear only when ink and pressure are applied. The useful thing is to agree a stop rule in advance. The press crew should stop, quarantine the affected sheets and wrappers, record the run conditions and inform the client promptly. Continuing to print defective stock in order to hit a deadline only increases the loss.
The client then needs a clear choice: replace the stock, accept a adjusted quality, or abort the run. Additional press time caused by defective supplied stock should be chargeable unless the printer caused the defect. If the printer caused it, the printer should replace the stock and absorb the associated time. That division is fair and easy to explain.
A short schedule to sign
A one-page stock schedule can prevent most disputes. It should record the agreed specification and any approved equivalents; the quantity supplied, including make-ready and spoilage reserve; the delivery window and goods-in contact; the inspection and conditioning period; who bears the cost of replacement stock and extra freight; the stop-and-report protocol for press faults; and the named contacts on both sides. It does not need to be a legal document. It needs to be accurate and shared before the pallets arrive.
Client-supplied paper works best when it is treated as a shared-cost arrangement with clearly allocated risks. The printer is not being distrustful by asking for a specification and a spoilage allowance, and the buyer is not being difficult by asking what happens if the stock fails. The conversation is simply easier before the paper is on the floor.
