A UV printer specification sheet is a list of limits, not a promise of output. The same machine can be quoted at three different speeds, and the print area, the media limits and the ink channels each describe a boundary rather than a result. Buyers who read the sheet as a set of answers rather than a set of conditions choose the wrong platform.

This guide works through the figures that appear on an industrial UV flatbed specification and explains what each one controls: the published print area, the printhead and channel counts, the speed modes, the media limits, the ink and curing data, and the power, size and weight figures that decide whether the machine can be installed where you planned. Every figure below is taken from the published product pages for this range rather than from a generic industry table.

Why does a specification sheet mislead a buyer?

Because every figure is true only under stated conditions.

A specification is a boundary or a mode, not a rating, so a number quoted without its condition cannot be compared with a competitor number or used to estimate real output.

The problem is not that suppliers pad the sheet. It is that a specification sheet compresses three different kinds of information into one column. Some figures are physical limits, such as the maximum part that fits the bed or the maximum thickness the head can clear. Some figures are options, such as a printhead count that can be upgraded. And some figures are measured results, such as a square-metre output that holds only in one quality mode. Read as one list, they look comparable. Read correctly, they answer different questions.

The published pages for this range are unusually explicit about which is which. They separate the platform limit, the configuration option and the measured mode, and they warn that headline output changes with material, resolution, pass count, coverage, loading and inspection. A buyer who wants a defensible comparison should keep those three categories apart on their own sheet as well.

What does the published print area really describe?

The maximum single piece the bed can hold.

The print area is a geometric limit for one sheet or part, and it says nothing about the margin you need for loading, the flatness of the material, or how many pieces nest on the bed at once.

Across this range the published print areas run from 1200 × 600 mm on the compact AJ1206, through 2500 × 1300 mm on the AJ2513G/R and 2100 × 3000 mm on the AJ2130G/R, to 3200 × 2000 mm on the AJ3220G/R. Those are the four numbers a buyer usually compares first, and they are the four that matter least on their own, because the usable area for a given job is always smaller than the published maximum.

Two deductions follow. First, a job that sits inside the print area can still fail on the margins needed for hold-down, cut clearance or edge quality, so the real question is not whether the part fits but whether it fits with the process around it. Second, a larger bed is not automatically more productive, because a bigger platform with the same head count can be slower per square metre. The published comparison for 4×8 sheets makes this point directly: all three wide platforms accept the sheet, and the correct choice still depends on which one runs the production mix best.

How many printheads and channels do you actually need?

Enough channels for the ink set and heads for the speed.

The channel count decides which inks can be laid down, while the head count decides how fast the same image can be produced at an acceptable quality.

Those two figures are often read as one, and they are not. The compact AJ1206 is published with a four-head configuration that can be upgraded to eight, using a CMYK plus white plus varnish ink set. The wide AJ2130G/R is published with an extended eight-colour system adding light cyan and light magenta, and the same platform can carry up to eight printheads. Counting heads tells you the platform’s throughput ceiling; counting channels tells you whether the effects you want are available at all.

The practical consequence is that a job needing a white underbase, a spot varnish and full colour needs a configuration that has those channels, and no amount of extra heads substitutes for a missing channel. Equally, a job that only needs four colours gains nothing from light inks it will not use. The right count is the one that matches the artwork, not the largest number on the page.

Why does a print speed need a mode label?

Because speed is quoted at a chosen quality setting.

A square-metre figure is meaningless without the mode it was measured in, and manufacturers usually publish three: a draft or ultra-draft mode, a standard production mode and a premium quality mode.

On this range the same platform is published with quite different figures per mode, and the difference is large enough to change a capacity plan. The AJ2130G/R eight-colour platform is quoted at 48.3, 34.9 and 27.9 square metres per hour across its modes. The higher-head AJ2130EX is quoted at 128.6, 92.9 and 74.6, and the AJ3220EX at 154.3, 111.5 and 89.6. A buyer who compares the AJ2130G/R draft figure with the AJ3220EX premium figure is comparing two different jobs.

Two rules keep the comparison honest. Quote every figure with its mode, and estimate capacity from the mode you will actually run in production rather than the fastest one on the sheet. The published guidance for a single application makes the same point from the other direction: the AJ1206 is quoted at up to 2,000 coins per hour, and that figure describes one specific coin workflow rather than the platform in general.

What media limits should sit beside the print area?

Thickness, weight per area and weight per piece.

Three separate limits govern what the bed accepts, and exceeding any one of them stops the job before print quality is raised, so all three belong in the same row as the print area.

The compact AJ1206 is published at 0 to 35 mm media thickness and a maximum media weight of 36 kg, and the wide platforms are published at 1 to 100 mm thickness and 50 kg per square metre. Read together with the print area, those figures describe a box rather than a line. A part that fits the width and the length can still fail on thickness or on mass, and a part that fits all four can still fail on surface, because a listed material is not automatically production-ready.

Which ink, curing and file figures decide the material range?

Ink configuration, curing type and the data path.

The ink configuration tells you which effects are possible, the curing type tells you how the ink sets, and the interface limits how large a file can be sent reliably to the machine.

Across this range the published ink configurations move from CMYK plus white plus varnish on the compact AJ1206 and the AJ2513G/R, through an extended seven-colour set on the AJ3220G/R, to an extended eight-colour set on the AJ2130G/R. Curing is UV LED across the range, which is what allows the ink to set on heat-sensitive materials that a conventional dryer would distort. Resolution is published up to 300 × 2400 DPI on the compact platform, and the RIP options differ by model, from RIIN Print and PhotoPrint on the AJ2130EX and AJ2130G/R to a wider set including Onyx on the AJ2513G/R and AJ2130Ultra.

The data path matters more than it usually gets credit for. The published interfaces include fibre optic, USB 3.0 and Ethernet, and a multi-layer file with white and varnish channels is much larger than a flattened image. A machine whose interface cannot move that file smoothly adds a delay to every job, which is why the interface belongs in the comparison rather than in a footnote.

What do the power, size and weight figures commit you to?

Site work that must be finished before delivery.

Electrical supply, footprint and net weight are installation constraints, and they decide whether the machine can be moved in, powered, ventilated and operated where you planned to put it.

The wide flatbeds in this range are published with an AC 220V, 50/60Hz supply drawing more than 20 amps, and the compact AJ1206 is published at AC 220V, 50/60Hz as well, with a net weight of 400 kg. The larger platforms are published at roughly 4172 × 4250 × 1390 mm and 1850 kg for the AJ2130 series, and 5272 × 2842 × 1390 mm for the AJ3220EX. Those are building decisions as much as machine decisions: doorways, floor loading, extraction and power routing all have to be checked before the order rather than after delivery.

Operating conditions belong in the same group. This range is published to run between 20 and 30 degrees Celsius and 40 to 60 percent relative humidity, with the AJ3220G/R published up to 80 percent non-condensing. A workshop that cannot hold those conditions will see variation in ink behaviour that no specification figure on the sheet predicted, which is exactly why the environmental range should be read as a requirement rather than a note.

How should two models be compared on one job?

Against your job, not against each other.

Fix the material, artwork, ink layers and quality mode first, and then compare how each candidate meets them, because a comparison without a fixed job becomes a comparison of marketing sizes.

The method is to build one table with a row for every requirement and a column for every candidate, then fill it from the published figures only. The comparison is decided by the rows that matter to your work, not by the total number of cells one model can fill. The published comparison pages for this range work the same way, setting out the bed, the head configuration and the print area per model, then stating that actual output still depends on the material, the file and the handling.

Two published figures outside the product tables are worth adding to the comparison. The first is the operating cost, published across the range at roughly 0.80 to 1.20 US dollars per square metre of ink, which turns a speed comparison into a cost comparison. The second is the support model, published with remote resolution of more than 80 percent of issues, a dispatch target of 48 hours and technicians in several regions, which decides how much of a stoppage you carry yourself. Neither number is a specification of the machine, and both change the answer.

Where a figure cannot be verified against the published pages, it should be recorded as unverified rather than filled from a competitor sheet. The point of the exercise is a decision you can defend, and a comparison is only as good as the figures it rests on.

What the decision comes down to

A specification sheet answers a comparison question, not a purchase question. Read the print area as a geometric boundary, the head and channel counts as configuration, the speed as a figure tied to a mode, and the media, power and environment figures as limits you have to live inside.

Compare candidates against one fixed job, on the mode you will actually run, and confirm the result with a printed sample and a timed batch. The published figures for this range are set out on the AJ2130G/R and AJ2130EX pages, with the wider platform comparison in the wide-format collection and the high-head detail on the AJ3220EX page.

Where a specification has to be verified rather than read, the relevant references sit outside the catalogue. Machine safety and supply requirements follow the applicable machinery rules (EU machinery), product safety certification is handled by recognised bodies (UL), and colour and process figures are covered by the industry bodies that publish them (International Color Consortium, Fogra, PRINTING United Alliance). Occupational exposure limits for a print workshop are set out by the relevant authority (HSE printing).
