Digital vs flexo: packaging print options for small runs

What to take away

How the two processes differ

Flexographic printing wraps a relief plate around a rotating cylinder, and every colour needs its own plate before the press can run. Digital printing sends the file straight to the press with no plate and no make-ready, so the first box and the last box cost broadly the same.

Flexo front-loads spend into plates, mounting and make-ready, then produces units cheaply once the press is running. Digital spreads cost evenly, which keeps short orders affordable overall but expensive per unit.

Where short runs tip the choice

Short runs mean more than small orders. They cover seasonal packs, limited editions, several SKUs in one order, market tests and personalised versions. Digital handles variation cheaply because nothing physical changes between versions.

Flexo still suits long repeat runs, larger corrugated formats and jobs where the design will not change for months.

Substrate and format limits

Digital presses such as the HP Indigo 30000 take sheets up to about 750 by 1050 mm and board up to about 600 microns. Narrower digital label webs from Xeikon typically run under 520 mm wide.

CI flexo presses, by contrast, run wider webs, often 800 mm to 1600 mm, and handle corrugated board well beyond digital caliper limits. Flexo also takes films, labels and recycled stocks that digital presses may need primed or treated.

Confirm the maximum sheet or web width, the board caliper and any priming requirement before you specify material.

Comparing the two routes for short runs

What decides the total cost

Three things drive the answer: run length, the number of artwork versions, and whether the job needs plates or a cutting die.

Take an illustrative four-colour job. Suppose the plate and make-ready charge is £500, used here only to show the arithmetic. At 500 boxes, that adds £1.00 per box. At 50,000 cartons, it adds 1p per carton. Digital skips the £500, so it wins the 500-box order unless its unit premium is more than £1.00.

The two routes are easiest to judge against one written specification, and comparing packaging supplier quotes on the same basis stops a low headline figure from hiding plate or die charges.

Treat any crossover point a supplier gives you as specific to that press and that substrate. Board and film prices move, so a quote is only reliable for its stated validity period.

A sample-first process for short runs

Samples on production stock show how ink sits on recycled board, how colours shift between versions and whether the pack still feels right in the hand.

Materials, artwork and UK packaging duties

Material choice feeds into print choice. Businesses with turnover of £2 million or more and handling 50 tonnes or more of packaging a year must register and report packaging data under the extended producer responsibility rules in the Producer Responsibility Obligations (Packaging and Packaging Waste) Regulations 2024. Lighter packs and fewer material types reduce what you have to record.

Artwork is where short runs are won or lost. Fine lines, reverse type and small logos behave differently on a plate than on a digital press. The common packaging design mistakes that hurt unboxing surface fastest on a run you cannot reprint cheaply.

Common questions

Is digital printing cheaper than flexo for small runs?

Usually, for short runs, because there is no plate charge. The crossover moves with plate count and make-ready time.

Can flexo print a run of 1,000 boxes?

Yes, but plates and make-ready are spread across only 1,000 units. The price per box will often look poor next to a digital quote.

Do I need new plates when artwork changes?

Yes, for any changed colour layer, because the plate carries the image. Digital has no equivalent charge, which is why versioned packs lean that way.

How quickly can a short run be printed?

Digital work can often be scheduled within days of artwork approval, while flexo needs time for plates and make-ready. Confirm dates in writing with your supplier.
