Offset vs digital printing: how to choose by run size
The most common question a print buyer faces is not about paper or finish. It is offset or digital. The honest answer depends almost entirely on quantity, and the economics behind that answer are simple once you see them laid out.
How each process works
Offset printing transfers ink from etched aluminium plates onto a rubber blanket and then onto paper. Every job needs plates made, the press set up, and colour brought into register before the first sellable sheet comes off. That setup takes time and materials regardless of whether you print one thousand sheets or one million.
Digital printing works more like a very large office printer: no plates, no lengthy setup. The file goes to the press and sheets come out. Sheet one costs roughly the same as sheet five thousand.
Quality on modern digital presses is close enough to offset that most buyers cannot tell on a brochure. The differences show at the edges: offset handles heavier boards, larger sheet sizes and specialty inks that digital presses cannot, and its colour holds steadier across very long runs.
The economics of run size
Offset carries a fixed setup cost and a very low running cost. Spread the setup across a long run and the price per unit falls steeply. This is why offset houses set minimums: at PrintVision the offset minimum is 50,000 units, because below that volume the setup cost dominates and the job stops making sense for the buyer.
Digital is the mirror image: almost no setup cost, but a higher cost per sheet that never falls. For 200 brochures it wins comfortably. For 200,000 cartons it loses badly.
Where digital wins
Choose digital for short runs, prototypes and pre-launch samples, and for jobs where every piece differs: numbered invitations, personalised direct mail, versioned packaging mockups. Turnaround is faster because there are no plates to make.
Digital is also the sensible way to test. Print a few hundred packs digitally, put them in front of customers, and commit to an offset run once the design is settled. Many packaging buyers run exactly this sequence: digital for the pilot batch, offset for the launch order.
Where offset wins
Above the crossover point, offset delivers lower unit cost, a wider choice of substrates and thicker boards, Pantone spot colours mixed as real ink, and consistency that holds sheet after sheet across a run of hundreds of thousands. For product packaging, labels and cartons at commercial volume, offset remains the standard.
Offset also pairs naturally with the finishes packaging needs: UV coating, lamination, foiling and embossing are all built around offset-printed sheets.
A simple decision rule
Under a few thousand units, or variable data on every piece: digital, no debate. Tens of thousands and above, on a settled design: offset, and the more you print the stronger the case. In the grey zone between, ask your printer to quote both ways and compare the unit price with your own forecast of repeat orders.
One caution: do not print an offset-sized run just to hit a lower unit price if the design may change. Fifty thousand cartons with last season's artwork are worth nothing. Match the run to how long the design will genuinely stay current, and remember that a repeat offset order is cheaper than the first, since the plates and dies already exist.
Finally, choose a printer that runs both processes honestly. A house with only one kind of press will recommend the press it owns. A supplier that operates offset and digital side by side can quote your job both ways and let the numbers argue.
