Offset buries its cost in plates, make-ready sheets and spoilage before the first saleable copy, then runs cheaply per sheet once the press settles. Digital pays by the click. Each estimate uses different lines, so the crossover run length must be worked out for every job and never guessed from habit or a rule of thumb.
Where the cost sits in an offset job
An offset job pays up front. Each colour needs a plate. Plates, blankets, ink and wash-up all land on the job before the first good copy leaves the delivery pile, whatever the final quantity turns out to be.
The press also needs make-ready, so the operator runs and bins sheets until ink balance, register and colour settle, and only then does a saleable sheet appear. Once the press is running, each extra sheet costs little and paper dominates the bill, so the estimate has a large fixed block and a thin per-thousand rate. Short runs suffer badly.
- One plate per colour per side, including spot colours
- Make-ready sheets, counted as paper you cannot sell
- Press hours at the rate for that machine
- Ink coverage for the artwork, heavy solids cost more
- Binding and finishing lines added afterwards
Where the cost sits in a digital job
A digital press has no plates. File prep, a proof and a short colour check replace them, and setup is quick enough that a run of fifty copies carries no heavy fixed block.
Every page carries a charge. Most contracts charge a click per impression, a higher click for colour and a higher one for oversize, with toner and drum wear sitting inside it. The meter reading becomes the cost basis.
- Click charge by colour, mono and sheet size
- Duplex counts as two clicks per sheet
- Variable data adds file preparation time
- Paper stock limits, since not every board feeds
Run length decides which estimate wins
Plot both costs against quantity. Offset starts high and climbs slowly, digital starts near zero and climbs in a straight line, and the lines cross where paper, colours and page count dictate.
Work it out for each job. A two-colour leaflet and a four-colour brochure with spot varnish cross at very different quantities, because plate count, make-ready time and click rates differ between them. No rule of thumb travels between products.
- Quantity, colours and sheet size
- Plate count against click count
- Make-ready paper against zero spoilage
- Delivery date, since plates add a day
What each method does to spoilage and scheduling
Offset spoilage is planned. The estimator adds waste sheets for make-ready and for every fold or guillotine cut downstream, and a bindery that spoils more than its allowance eats the margin quietly. Offset also carries wash-up waste between colour changes, and a job with a spot varnish adds a coating pass that raises the spoilage allowance again.
Digital waste is smaller but not zero. Jams and colour drift still cost sheets. The scheduling effect is bigger. Offset jobs wait for a press slot and for plates to dry, while digital jobs can fill gaps between larger work and ship the same afternoon.
Build the estimate from separate lines
Keep one estimate template per method. Offset lines carry plates, make-ready, press hours, spoilage and finishing, while digital lines carry clicks, file prep, stock and finishing, and mixing them in one sheet hides the crossover.
When a customer asks for the same job both ways, show both totals side by side, which ends the price argument sooner than any explanation of plates or clicks. Pull ten recent jobs. Rebuild each on the other method and see where your own crossover falls, using the same paper, colours and page count as the original quote.
Offset or digital crossover worksheet
Offset and digital each get a column on this single-page worksheet, with rows for plates, make-ready sheets, press hours, click charges, file prep, stock, spoilage and finishing. A last row totals each column. Cost per copy is repeated at three quantities, so the crossover is visible at a glance between the two columns, before anyone draws a chart or opens a spreadsheet.

Is digital always cheaper for short runs?
Usually, but not always. Heavy ink coverage, an oversize sheet or a duplex click on both sides can narrow the gap, so run both estimates before you quote and compare the totals.
Why does offset need make-ready sheets?
Before the run is saleable, the operator balances ink, registers the plates and checks colour against the proof, using sheets that become scrap. Cost them as paper and press time.
What is a click charge?
It is a fee per impression. Colour, mono and large formats usually carry different rates, duplex counts twice, and the meter reading on the press is what the supplier bills against.
Can one job mix both methods?
Yes. A cover may run offset with a varnish while the inside pages run digital, and each part is costed separately with the finishing added once at the end.
