TL;DR
- Offset prints from one metal plate per ink, so an ordinary full-color job needs 4 plates made and mounted before the first good sheet comes off the press.
- Digital needs no plates, so the price of a single sheet barely changes between 50 copies and 500.
- The point where offset gets cheaper usually sits somewhere in the hundreds to low thousands of sheets. That is a working range, not a law, and it moves with size, paper and ink coverage.
- Offset color is run against the targets in ISO 12647-2, and exact brand spot colors are still where it beats digital.
Short version: digital wins short runs and last-minute changes, offset wins long runs and exact color. Picking the process before you know the quantity is the expensive mistake.
For most small-business jobs, the choice between offset and digital printing comes down to one number: how many copies you need. Under a few hundred, digital is almost always cheaper and faster. Once you are into the thousands, offset usually is, because its setup cost gets spread across every sheet. Between the two there is a gray zone where paper, size and color decide it.
Most people pick based on which sounds more professional. That is the wrong question.
How each process gets ink onto paper
Offset lithography transfers ink from a metal plate onto a rubber blanket, then from the blanket onto the paper. Each ink color has its own plate. Standard full-color work uses four inks (cyan, magenta, yellow and black), so four plates. Add a brand spot color and you add a fifth.
Digital presses work more like a very large, very fast office printer. Toner or liquid ink goes straight from the machine to the sheet, built from the file each time. Nothing has to be made before the run starts, which is also why every sheet can be different if you want it to be.
The setup cost that decides the run
Offset’s cost is front-loaded. Plates have to be imaged, mounted and inked, and the first sheets through the press go into the waste pile while the operator brings color and registration into line. You pay for that whether you print 200 copies or 20,000.
Digital flips it. Almost no setup, but the per-sheet cost stays roughly flat however many you order. So the question is never “which is cheaper?” but “cheaper at what quantity?”
| What changes | Offset | Digital |
|---|---|---|
| Setup before printing | Plates, makeready, waste sheets | Almost none |
| Cost per sheet as the run grows | Falls steadily | Stays roughly flat |
| Exact brand spot color | Mixed ink, run on its own plate | Simulated from four colors |
| Different content on each copy | Not practical | Built in |
| Fixing a typo after approval | New plate | New file |
Where the crossover usually sits
There is no universal break-even quantity, and any printer who quotes you one without asking about the job is guessing. In practice it tends to fall somewhere between a few hundred and a couple of thousand sheets. A two-sided A5 flyer on standard coated paper reaches it sooner than a small run of heavy card with a spot color, because the card eats more of the digital press’s time per sheet.
So the useful move is to ask for both quotes at two or three quantities, say 250, 1,000 and 2,500. You will see the curve for your own job instead of trusting a rule of thumb.
Why a shop that runs both is easier to work with
A printer that owns only one kind of press has a reason to push every job onto it. One that runs both can simply tell you which is cheaper for your quantity. Impression.ma, a print shop in Tangier, runs offset and digital small format in the same workshop for business cards, flyers and brochures, and quotes cards and flyers at 24 to 48 hours. That is the setup you want when the quantity is in the gray zone and you would rather hear the answer than argue about it.
It also makes mixed campaigns simple. A long run of flyers can go offset while a short run of personalized invitations for the same launch goes digital, on matching paper.
Color is where offset still earns its setup
If your brand lives on one exact orange or green, offset is the safer bet. It can print that color as a mixed ink on its own plate, and commercial offset shops work to the process-control targets in ISO 12647-2 for offset lithographic printing, which is what keeps one run looking like the last.
Digital builds every color out of its base inks. Modern presses get very close on most shades. Saturated oranges, certain greens and metallics are where the gap still shows, and it shows most when the digital piece sits right next to something printed offset.
Paper, size and finish move the line
Standard sizes keep both processes efficient. A5 and A4 come from ISO 216, the international standard for A and B series paper sizes, and they fit neatly on press sheets with little trimmed away. Odd sizes waste paper on either process, but the waste costs more on a long offset run.
Heavy stock, textured paper and finishes such as foil or spot varnish add their own setup steps. They can push a job toward offset even at modest quantities, or toward a digital print with the finish added afterward. Ask which your printer does. The two give different results on the same card.
Planning print around an event or launch
Launches and events are where the choice gets made in a hurry. Programs, badges and signage have hard deadlines, and the copy changes until the night before. Our look at how event agencies turn brand experiences into revenue gets into why those last-minute changes happen. For print, the practical rule is this: anything likely to change goes digital, anything fixed and printed in volume goes offset, and both get ordered early enough to reprint one if a detail is wrong.
The quantity comes first
Decide how many you need before you decide how to print them. Get two quotes at three quantities, look at where the prices cross, and let that pick the press. The flyers will look fine either way. What the choice really changes is the invoice.
