LEP Digital Press Cost Per Meter, Explained

The quote that didn't add up

An estimator gets a rate sheet back from the LEP press rep: so many cents per metre run. Fine — except the quote template on the shared drive is built around cost per thousand labels, because that's how every flexo job in the shop has always been priced. Nobody wants to be the one who mis-converts a per-metre number into a per-label price on a 40,000-unit reorder and finds out at invoicing that the math was off by a third. The instinct is to eyeball it, round generously, and move on. That works until the label repeat length changes, or the web goes from two labels across to four, and the eyeballed number stops being close enough.

By the end of this piece you'll be able to take any LEP click rate quoted per metre and convert it into a real per-label and per-thousand cost — one that changes correctly when repeat length, lanes-across, or run length change, instead of one that's just a guess dressed up as a number.

Why LEP presses charge by the metre, not the impression

Toner-based digital presses in the HP Indigo family (liquid electrophotographic, or LEP) don't charge the way a desktop printer does, and they don't charge the way flexo does either. A flexo press's real cost driver is the plate set, the makeready, and the run-rate — costs that are largely indifferent to how much ink actually lands on the substrate. An LEP press instead bills by the length of substrate that passes through the engine: a click charge per metre (or per linear foot, depending on the vendor's convention), independent of image coverage and largely independent of color count, because the ink stations don't consume plates or physical media the way flexo does.

That's the mechanism worth internalizing: the LEP click charge is a function of how much web moves through the press, not of how much ink sits on it. A label that's 90% coverage in five colors and a label that's a single spot color both cost the same per metre to run, all else equal. That's a genuinely different cost shape than either flexo (plate cost + makeready dominate) or UV inkjet (cost scales with measured ink coverage). Our HP Indigo cost per click breakdown goes deeper on how the per-click rate itself is structured and negotiated; this piece is about turning that rate into a number you can put on a quote line.

Converting a per-metre click rate into a per-label cost

The conversion has two moving parts: repeat length (how much web the label consumes in the direction of travel) and lanes-across (how many labels sit side by side on the web width). Multiply those together and you know how many metres of substrate one finished label actually costs — which is what the click charge is really billing.

Here's a worked example with round numbers, built to teach the method rather than assert a real rate:

• Repeat length: 100 mm (0.1 m) per label, in the direction of web travel
• Lanes across the web: 3
• Illustrative click rate: $0.20 per metre (a placeholder for teaching purposes — real LEP click rates are tiered, volume-negotiated, and vary by press generation and contract; never plug a number you haven't confirmed with your own press rep)

To produce 1,000 finished labels at 3-up, the press needs to advance:

1,000 labels ÷ 3 lanes = 333.3 metres of "label-lengths" per lane 333.3 × 0.1 m repeat = 33.3 metres of substrate run

At the illustrative $0.20/metre rate: 33.3 m × $0.20 = $6.67 in click cost per 1,000 labels, or $0.00667 per label.

Change the repeat length to 150 mm and the same lane count, and the metres-run figure rises proportionally — 50 metres instead of 33.3, and the click cost rises with it. Add a fourth lane across and the click cost per label drops, because more labels ride on the same metre of web. That's the whole mechanism: repeat length and lanes-across set how many labels you get per metre; the per-metre rate turns that into a cost. Nothing about color count or ink coverage enters the calculation, which is exactly what separates LEP economics from flexo and from UV inkjet.

The click charge tells you what a metre of web costs to run. Repeat length and lanes-across tell you how many labels live on that metre. You need both numbers before "cost per metre" means anything on a quote.

Where the click charge stops and your real cost starts

The per-metre click cost is one line item, not the whole quote. It typically covers the press engine's run cost — but the label still needs substrate (priced separately, usually by MSI the way flexo substrate is), any laminate or overlaminate, finishing (die-cutting, slitting, rewinding), and your shop's overhead and margin loaded on top. A converter who quotes the click cost alone and calls it done is under-pricing the job by everything the press doesn't touch. The digital label press cost per metre piece walks through stacking these layers into one number; the click-charge estimating guide covers how to negotiate and structure the click rate itself so the number you're converting is a real one, not a rack rate.

Putting LEP next to flexo and UV inkjet on the same quote

The reason this conversion matters isn't just LEP accuracy — it's that a converter with more than one press type needs to know, for a given job, which press actually wins. Flexo cost is dominated by plate and makeready, which amortize better at higher volumes; LEP cost is driven by metres run, which scales linearly with quantity regardless of coverage; UV inkjet cost scales with measured ink coverage plus any white-ink or speed penalty. Those are three different cost shapes, and a short-run job with heavy coverage can land somewhere completely different than a long-run job with a light spot-color image — even on the same substrate.

One industry analysis of HP Indigo TCO puts the digital-versus-flexo crossover at roughly the 500-unit mark for label jobs, with digital pulling ahead economically above that line and flexo ahead below it — though the exact break-even always shifts with colour count, label geometry, and the plate cost you've actually configured, so treat any single number as a starting reference rather than a rule. That's precisely why FlexoCommand's flexo engine, LEP click-charge engine, and UV inkjet engine sit on the same all-machine comparative quote, with the crossover highlighted automatically once you enter a job's repeat length, lanes-across, coverage, and quantity — rather than requiring three separate spreadsheets and a manual eyeball comparison. For the full mechanics of all three digital cost models side by side, see digital label press cost models compared; for the foundational math this all builds on, the label estimating complete guide is the starting point.

Build the conversion once, reuse it on every LEP quote

The repeat-length × lanes-across × per-metre-rate calculation above is simple once you've done it twice, but rebuilding it from scratch on every job invites the same rounding errors that got the estimator in trouble at invoicing. The Digital LEP (Click-Charge) Estimating Workbook sets up that conversion as a reusable template — repeat length, lanes-across, and your negotiated per-metre rate go in, a defensible per-label and per-thousand cost comes out, ready to sit next to your flexo and UV inkjet numbers on the same quote.
