Offset vs digital printing: which is cheaper for your quantity?

Where the offset set-up cost actually comes from

An offset press cannot print from a file. The file is imaged by laser onto an aluminium printing plate, one plate per colour: four for a CMYK job, and one more for every spot or Pantone colour. Those plates are then mounted on the press, the ink keys set, the colours brought into register and the sheet run up to the approved colour. That whole preparation is make-ready, and it consumes press time, operator time, ink and a quantity of waste sheets before a single saleable sheet comes off.

None of that scales with quantity. Make-ready for five hundred cartons takes the same time as make-ready for fifty thousand. Spread over five hundred units it dominates the price of each one; spread over fifty thousand it disappears into the noise. That single fact is the whole economics of offset, and almost everything else on this page follows from it.

Why digital has no equivalent

A digital press images directly from the file on every impression. There is no plate, so there is nothing to make, mount or register. The first sheet costs about the same as the thousandth. That is exactly why digital exists commercially: it made short runs viable that offset could never price.

The trade-off is on the other side of the ledger. The consumable cost per sheet — toner or ink, the click charge on the machine — is higher than the ink on an offset sheet, and it does not fall with volume. So digital’s unit price is a nearly flat line, while offset’s is a curve that starts high and drops. Where the curve crosses the line is your break-even.

What moves the break-even

Three things decide where the crossing point sits for a specific job.

Colour count. Every additional offset colour is another plate and more make-ready, which pushes the break-even higher. A one-colour job on kraft breaks even at a far lower quantity than a six-colour job with two Pantones. On digital, colour count barely matters — a four-colour image costs what a one-colour one costs.

Sheet size and ups. Offset presses run large sheets, and imposition fits as many copies onto each sheet as the geometry allows. A small item that fits twenty-one up makes offset efficient very quickly; a large item that fits two up does not. Digital presses are generally smaller-format, so the same logic applies but with a smaller sheet.

Finishing. Lamination, foil, embossing and die-cutting are separate passes on separate machines, and their costs are roughly the same whichever press printed the sheet. They do not move the break-even much, but they do raise the whole job — and some finishes behave differently on digital output, which is a reason to prove the finish on a sample regardless.

What you give up on each side

The searches that bring people to this page ask about the disadvantages of each process, so here they are plainly.

Offset’s disadvantages. It is slow to start, because plates and make-ready happen before anything is produced. Short runs are expensive for the same reason. Every copy is identical — it cannot print a different serial number or name on each sheet. And a change after plates are made is a new set of plates, not an edit.

Digital’s disadvantages. The unit cost stays high at volume, so a long run costs materially more than it would on offset. Colour is a process simulation: a digital press builds every colour from its own four inks, so it cannot lay down an exact Pantone spot colour the way an offset press can. The finishing range is somewhat narrower, some substrates are off-limits, and very large solid areas can show unevenness that offset would not.

The types of offset printing, briefly

“Offset” on its own usually means sheet-fed offset lithography: individual sheets fed through a press, which is what a packaging and commercial printer runs and what everything above describes. Web offset feeds a continuous roll instead of sheets and is built for newspapers, magazines and very long runs of lightweight paper, where its speed outweighs its coarser finish. Waterless offset replaces the damping system with a silicone plate and is used for fine-screen, high-consistency work. For cartons, labels, catalogues and stationery, sheet-fed is the relevant one.

A worked comparison

Rather than a price table — which would be wrong for your job the moment your sheet size or colour count differed — here is how the two processes behave across the decisions that actually matter.

Jobs we put on digital even when offset is the bigger invoice

There is a commercial temptation for any press to steer work onto offset, because the invoice is larger. We would rather tell you when it is the wrong answer, so here is where digital wins on merit regardless of quantity.

Anything with variable data. Serial numbers, unique QR or DataMatrix codes, personalised names, versioned addresses. Offset physically cannot do it; the plate is the plate. If every unit has to differ, the job is digital, full stop.

Prototypes and pre-launch samples. A digital printed sample on the production board tells you most of what an offset pre-production sample would, at a fraction of the cost and in a fraction of the time. It is one of the four tiers of our sampling stage, and we use it constantly.

Many versions, each short. Twelve flavour variants of a carton at a few hundred each is twelve offset make-readies — or one digital job. Even if the total quantity would be economical on offset, the version count kills it.

Genuine urgency. When the deadline is tomorrow, the hours of plate-making and make-ready are hours you do not have.

And the reverse is equally true: a long run of a single design with an exact brand colour belongs on offset, and we will say so even when digital would have been quicker for us to schedule.

How to get an honest answer for your job

Send the five details that decide it: what the item is, how many, what size, how many colours, and what finish. With those, the break-even for your specific job is a calculation rather than a guess, and we will tell you which press it belongs on — including when the cheaper answer is the smaller invoice for us. The quote form asks for exactly those five, for exactly this reason.
