To choose a digital printing machine, start from your order mix — the average batch size, the board types you print, and the box sizes you sell — and then match three specifications to that mix: printhead platform, print width, and production speed. A machine chosen this way pays for its role in your line; a machine chosen from a brochure alone usually does not.
I have spent the past ten years helping box plants on four continents pick their first digital press, and the most common mistake is always the same: buyers start with the machine and work backward to their orders. They fall in love with a speed figure, then discover the print width cannot fit their largest selling box, or the machine only prints four colors when half their orders need white ink on kraft. This article walks you through the selection sequence we use in our own factory when we configure machines — in the same order we would discuss it with you standing on your production floor.
The one-sentence rule: let your last three months of orders choose the machine — average batch size picks the technology, biggest box width picks the printing width, and peak delivery pressure picks the speed.
Step 1 — Start With Your Order Mix, Not the Spec Sheet
Before we talk about printheads or DPI, we ask every customer one question: what did your last 100 orders look like? We want to see three numbers — how many different designs you ran, how many boxes the average order contained, and how many orders needed to ship within a week. Those three numbers decide everything else on this page.
- Many designs + small batches → the changeover speed and plate-free workflow matter most
- Few designs + very large batches → the raw production speed matters most
- Mix of both → a single-pass line for the long tail plus digital for the short tail, or a 2-in-1 machine
There is no "best digital printing machine" in the abstract — there is only the machine that fits your mix. One of our customers in Southeast Asia runs 60 to 80 different prints every day on a 16-head Epson machine. Another, a large-volume converter, runs the same three designs for a single retail chain and needs a single-pass line at 45–110 m/min. Both bought from us, and both are happy — because neither tried to use the other's machine.
The mix check we run on every inquiry
If more than half your jobs are under 1,000 boxes, digital is almost certainly the right spine for your line. If more than half are above 10,000 boxes with no design change, put single-pass at the center. Everything in between is a configuration conversation, not a technology debate.
Step 2 — Match the Printhead Platform to Your Work
The printhead is the heart of any digital printing machine, and the three platforms we build around behave very differently. This is the point where many buyers realize their "same-looking" quotes hide completely different machines:
| Comparison | Epson platform | Xaar platform | Seiko platform |
|---|---|---|---|
| Head count options | 8, 12, 16, 24, 32 | 6, 9, 12 | 4 to 18 |
| Color channels | CMYK + White (5 colors) | CMYK + White (5 colors) | Single color |
| Resolution | 600 or 1200 DPI | Up to 1500 / 2500 max productivity | Single-color output |
| Print width range | 264–525 mm (wide single-pass to 1050 mm) | 200–400 mm | 400–1800 mm |
| Typical speed | 700–1500 m/h; 45–110 m/min single-pass | 500–1000 m/h | 70–110 m/min |
A quick guide from what we see in the field: if your plant prints full-color branding on corrugated and kraft, the Epson platform with five colors is the workhorse most customers pick. If you want maximum nozzle reliability on a mid-width machine, the Xaar platform (up to 1536 or 2560 active nozzles per head) is the choice many industrial converters trust. If your real need is extreme width — oversized sheets, large die-cut blanks up to 1800 mm — the Seiko platform is the only one that reaches there, and it prints single color. You can compare these lines on our Epson, Xaar, and Seiko series pages.
Step 3 — Size the Print Width to Your Largest Selling Box
Print width is the specification buyers most often get wrong, because they size it to their average box instead of their largest box. If your biggest selling carton is 480 mm wide and the machine prints 400 mm, that carton simply cannot go through it — you would have to rotate the design or turn the order away. We ask customers to bring us their top five best-selling box dimensions, and we size the machine to the largest of the five.
In the Epson line, that means choosing between 264 mm, 400 mm, and 525 mm standard widths, with wider single-pass configurations reaching 795 mm and 1050 mm for large-format work. The Seiko line steps up to 1800 mm for oversized sheets. The rule is simple: the machine width must cover the largest flat sheet you actually sell, with a small margin for bleed and registration — never the other way around.
Step 4 — Choose the Speed Mode That Matches Your Peak Load
Speed in digital packaging printing comes in two completely different languages, and confusing them is the fastest way to misconfigure a purchase. Multi-pass machines print in scanning passes and are quoted in meters per hour — our Epson multi-pass range runs 700–1500 m/h, and the Xaar range 500–1000 m/h. Single-pass machines print in one pass and are quoted in meters per minute — 45–110 m/min across our Epson single-pass and Seiko lines.
- Multi-pass — the right choice when orders are small and designs change constantly; the machine spends its time switching jobs, not running flat out
- Single-pass — the right choice when you need continuous high-volume output and the order book is stable
- 2-in-1 — one platform that runs both modes, for plants whose order mix swings between the two
When a customer asks us "what is the fastest digital printing machine you make?", we answer with a counter-question: how many boxes do you need by Friday? A single-pass machine at 45–110 m/min is unbeatable when the demand is steady; a multi-pass machine with one-minute changeovers is faster where the demand is diverse. The detail is on our multi-pass and single-pass pages, and the hybrid option on our 2-in-1 page.
Step 5 — Check the Ink Channels Before You Commit
Color capability decides which jobs a digital printing machine can accept, and this is where we see buyers get surprised later. If you print on natural brown kraft, a four-color machine will give you dull, muddy graphics — brown board eats the brightness of CMYK ink. The fix is a fifth channel: white. With CMYK + White, the machine lays down an opaque white base first and prints color on top, so brand colors stay vivid on brown stock.
Before you choose, list the substrates your customers actually send you. If kraft, honeycomb board, or any brown material appears in the mix, budget for the five-color configuration from day one. Retrofitting white ink capability later is a much bigger conversation than choosing it at order time. CMYK computer color matching is standard across our machines, which means the operator adjusts color on screen instead of mixing ink by hand — a detail your production manager will thank you for.
Step 6 — Plan for the Line, Not Just the Printer
The best digital printing machine setups we have installed are rarely a lone printer sitting in a corner. Our full Goking range can be connected to inline finishing units — a high-speed printing unit, a slotting unit, and an automatic stacking unit — forming a complete digital line. The same machines integrate with ERP systems, so job data flows from order entry straight to the press and production status flows back.
Ask your supplier how the machine connects to what you already own. If you already run a corrugator or die-cutter line, you want a printing machine that drops into that workflow instead of creating a new island. Our key features page lists the integration options we support across the range.
From Our Experience: Three Selection Mistakes We See Repeatedly
After configuring machines for hundreds of plants, these three mistakes come up again and again — and they are all avoidable:
- Buying the biggest speed, ignoring changeover. We once installed a single-pass line for a customer who discovered their real bottleneck was 40 job changes a day, not printing speed. A multi-pass machine with one-minute changeovers doubled their output where the "faster" machine could not. Speed matters only at the bottleneck.
- Skipping white ink to save budget. One packaging company signed for a four-color machine, then started winning kraft orders and spent the next year working around dull colors. Every one of those customers ended up asking us about upgrading to five colors.
- Forgetting the space. A machine is one thing; the feed area, the dry-end handling, the finished-box stacking, and the maintenance aisle are another. Measure the room before you order, not after the crate arrives.
A Ten-Point Selection Checklist for Your Digital Printing Machine
Print this list and walk through it with your production manager before you open any quotation:
- What was your average batch size over the last 90 days?
- How many different designs do you run per day, per week?
- What is the width of your largest selling flat sheet?
- What board types do you print — corrugated, kraft, coated paper, honeycomb?
- Do any orders require white ink under the colors?
- What is your peak weekly delivery pressure?
- Do you need 600 DPI or 1200 DPI for the fine-textured jobs?
- Will the machine feed inline to slotting and stacking?
- Should job data flow into your ERP automatically?
- How much floor space — with service clearance — can you give it?
FAQ — Selection Questions Buyers Ask Us Every Week
Should I buy a multi-pass or single-pass digital printing machine?
Match it to your order volume. Multi-pass (500–1500 m/h) fits changing, smaller batches with frequent job switches. Single-pass (45–110 m/min) fits steady high-volume output. If your mix swings between both, consider a 2-in-1 platform.
How many printheads do I need?
More heads mean wider coverage and higher speed per pass. Epson platforms offer 8 to 32 heads, Xaar 6 to 12, and Seiko 4 to 18. Let your width and speed requirements decide, not a round number.
Is 600 DPI enough for corrugated packaging?
For most corrugated and kraft work, 600 DPI looks clean and prints faster. Choose 1200 DPI when your jobs include fine text, small logos, or premium coated-paper work where detail matters more than speed.
Do I need white ink?
Only if you print on brown or transparent stock. On kraft, honeycomb board, and natural corrugated, a CMYK + White configuration keeps brand colors bright. On white-coated paper, four colors are usually enough.
Can the machine grow with us later?
Our platform scales by head count — an 8-head machine can be configured toward 16, 24, or 32 heads as volume grows, and single-pass upgrades share the same transport and ink architecture. Talk to us about your five-year plan before you order.
Final Word: The Right Digital Printing Machine Is the One Matched to Your Orders
Choosing a digital printing machine comes down to six decisions in order: order mix, printhead platform, print width, speed mode, ink channels, and line integration. Answer them honestly and the machine practically selects itself — that is the experience we bring to every factory we visit, and it is why our customers usually confirm their configuration in a single meeting instead of months of back-and-forth.
If you send us your top five box sizes, your average batch size, and the board types you run, we will come back with a recommended configuration — the same analysis we run for every Goking customer before they sign anything. That conversation costs you nothing and it will tell you exactly which machine belongs on your floor.
