What is make-ready? It is everything a press does between the previous job and a saleable sheet: mounting plates, setting ink, aligning registration, adjusting pressure, and pulling sheets until the colour and fit are right. The sheets pulled in that period are waste. The job only starts producing sellable board once the printer has a sheet that matches the approved proof, and that moment defines where the useful run begins.
Why does make-ready matter more on a short run? Because the setup is a fixed cost in sheets and time, and it is spread over however many boxes are ordered. On a run of 50,000 the waste is a rounding error; on a run of 1,000 the same setup can be a noticeable share of the price. This is the mechanism behind the familiar curve where a small order costs disproportionately more per unit, and it is covered from the costing side in the box cost breakdown.
Which design choices increase the waste? Every extra colour adds a plate, an ink station and a matching step. A spot colour adds a wash-up and a colour match. Heavy ink coverage takes longer to reach density, especially with light colours over dark. Tight registration between fine elements means more sheets pulled before the fit is acceptable. Designing with fewer colours and less fussy registration is a real cost lever, not an aesthetic one.
How does sheet layout change the number? A layout that nests more boxes per sheet amortises the setup over more units, so the same make-ready waste is divided by a larger output. That is why a slight change in box size can move the price more than a change in board grade: it decides whether the die fits the sheet economically. The principles are set out in the note on imposition and nesting.
Where else does waste accumulate outside the press? Die-cutting has a make-ready of its own – setting the cutting pressure, adding the stripping pins, checking the crease depth. Gluing has a startup where the first boxes are checked and discarded. Hand assembly adds a learning curve. A quote that mentions only printing waste is describing part of the process, and the guide to cutting box costs covers where the rest sits.
Can waste be reduced without changing the design? Sometimes. A factory can gang a small job with another of the same board and colour, sharing the make-ready across both. It can print a slightly longer run than ordered and hold the surplus, which often costs less than a second setup later. It can agree a wider colour tolerance for a non-critical panel. Each of these is a negotiation rather than a specification, which is why it is worth asking explicitly.
What should a buyer ask about setup? Ask how many sheets the make-ready consumes on the chosen press, whether setup is billed separately or inside the unit price, and what the price looks like at two or three quantity levels. Then compare the price step between them – a steep drop suggests you are paying for setup, and consolidating orders into fewer, larger runs may beat chasing a lower unit rate. Quote structures are explained in the RFQ guide.
