We get this question every week.
A brand sends an inquiry for 2,000 custom printed cartons, then gets surprised when the unit price is far higher than the quote they received for 30,000 boxes. Most buyers assume the difference is just raw paper cost. From our production floor, that is only a small part of the story.
For large-volume orders, the biggest cost is the paperboard itself. Once plates are made and the press is set up, the machine runs continuously. Changeovers are rare, waste rate stays low, and labour cost per box drops sharply. This is the classic stable order we used to see often before multi-SKU packaging became mainstream.
Short-run jobs are different.
The fixed setup work stays almost the same whether you print 2,000 boxes or 20,000. File checking, plate making, press setup, die cutting tool preparation, machine calibration, and sample approval all take the same amount of our team's time. When you split one big order into multiple small designs, every new SKU triggers another full setup process.
One recent example: a client wanted four separate designs for a holiday gift carton, 2,500 pieces per design. Total quantity hit 10,000 units. Many would expect pricing close to a standard 10k single-design order. But the four separate setups pushed up setup time, material waste during press make-ready, and production scheduling. The total cost was nearly 35% higher than one single design of 10,000 cartons.
The hidden costs buyers often overlook
Press make-ready waste: Every time we switch artwork, we run blank sheets to adjust colour registration. This waste does not disappear on small runs.
Tool changeover time: Die-cut and finishing tools need swapping, testing and alignment between different box sizes or designs.
Higher risk of human error: More job switches mean more frequent job handovers in the workshop.
Slower line speed: Operators take extra care on short runs to avoid wasting limited stock.
This does not mean short runs are bad. Many beauty and consumer brands rely on limited editions, seasonal tests and regional variants to test market response. Short-run custom cartons are a powerful tool for product launches. The key is to understand what you pay for.
A few practical ways brands can reduce short-run packaging costs:
Combine designs with identical box size and same finishing (foil / spot UV) to cut tool change time
Keep artwork consistent on base paper type
Lock dielines and artwork early to avoid rework after setup starts
Group multiple small SKUs into one production window where possible
How Kinghorn Packaging balances short-run flexibility and quality
Our production team plans changeovers carefully when handling multiple small SKUs. We flag cost drivers at the quotation stage, so clients understand where the budget goes. We also suggest simple structural or artwork adjustments that can bring costs down without weakening the brand look.
Bottom line
Unit price alone is not the right way to compare small and large carton orders. Setup and changeover work create most of the price gap. Early communication about your full SKU plan helps us give you realistic pricing and better production scheduling.
Talk to Kinghorn Packaging if you are planning multi-SKU carton projects and want to optimise your packaging budget.
