Two days after the purchase order goes out, marketing wants a new claim on the front panel. Sometimes that costs nothing. Sometimes it costs a set of plates, the board already on order and a reprint. The difference is not the size of the change but the stage of production it arrives at, and knowing the stages makes the conversation much shorter.
What counts as a change order? Any instruction that alters what was agreed at order confirmation: copy, colours, dimensions, board grade, finish, quantity, packing configuration, delivery split or delivery date. Changes to the delivery address or the shipping marks are administratively simple but still belong in writing. The reason to treat all of them as formal is that production planning runs off the confirmed job ticket, and an instruction given verbally to a sales contact may not reach the press schedule.
Which changes are still free? Text and artwork edits made before the file is released to prepress, when no plate or die exists and no material has been cut. At that stage a revised PDF, a new proof and a fresh approval cost time but rarely money. Delivery date shifts that stay within the confirmed production window are usually free as well, provided the material has not been committed. Anything that changes a dimension after the die is ordered is a different conversation.
Where are the cut-off points? Four stages matter. Before artwork approval, changes are cheap. Between approval and plate or die making, a change costs tooling but not material. After plates are made and board is ordered, the cost includes the tooling, any material already purchased and the machine time lost in rescheduling. After printing has run, a change means a reprint, and the whole cost lands on the buyer unless the fault was the printer’s. Ask your supplier to state these cut-off points in the order confirmation rather than discovering them under pressure.
What drives the cost of a late change? Material commitment is usually the largest line, especially where board was made to order or a speciality paper was imported. Tooling comes next, since a cutting die or a set of plates cannot be reused for a different layout. Then there is the scheduling effect: a press slot given up may not be recoverable in the same week, so the delay costs more than the change itself. The cost breakdown article shows how those lines sit inside the unit price.
How do quantity changes work? Increasing quantity after the material is ordered usually means a second run, priced as a new job rather than at the original unit rate. Reducing quantity is harder, because material may already be cut, and the supplier is entitled to recover the committed cost. Where the reduction is small and falls inside the over or under tolerance agreed at order, it can often be absorbed, which is one reason the tolerance clause is worth reading before signing. The guide to MOQ tiers and bulk ordering covers how that allowance is normally set.
Who owns the stock left over from a change? That depends entirely on what the contract says, and many contracts say nothing. Where the supplier has bought material or printed components against a confirmed order, the buyer generally bears the cost of what cannot be used elsewhere. Custom printed cartons have almost no resale value, so the practical outcome is a charge or a write-off. Agreeing a cancellation and change clause at quotation stage avoids the argument later, and the ownership question for tooling is closely related, as the guide to asking for packaging quotes usually brings out.
How should a change be documented? A revised purchase order or a written change note that states what changed, the cost impact, the new delivery date and the approval of someone authorised to commit. Email is fine as a record as long as both sides confirm. What causes trouble is a chain of messages where the artwork revision is implied rather than named, and production ends up running the wrong file. Naming the file and the revision in every message is the least costly insurance available.
How can changes be avoided altogether? Freeze the artwork for a defined window before the confirmed production date and treat that date as a commitment rather than a suggestion. Route sign-off through one person on the buyer side so that marketing and regulatory both clear the same file. And where a launch date is fixed, order a small advance batch for the first channel rather than trying to hold one large order open for late edits.
