Most print shops know what their machine costs and very few know what a job costs. The difference appears at the end of the year, when a busy quarter has produced revenue without profit and nobody can say which work caused it.

This guide covers how to cost a UV printing job properly: why shops under-cost, what belongs in the calculation, how machine time is measured, how waste is counted, what a quote should state, how small runs are priced, what margin covers a remake, and what records turn the next quote into arithmetic rather than estimation.

Why do most print shops under-cost their work?

Because the visible costs are the smallest ones.

Ink and media are easy to count, while loading, inspection, waste and machine time are usually left out, and those are the costs that decide the margin.

The pattern is consistent across the industry. A shop prices a job from ink and material, adds a percentage, and considers itself finished. The shop has then priced the two costs that are easiest to see and omitted the four that are largest: the labour to load and inspect, the machine time the job occupies, the material lost to setup and rejects, and the overhead that keeps the lights on.

The published guidance for this range points at the same gap from the other direction when it asks for the complete cycle to be timed rather than the print alone. Loading, positioning, artwork changes, resolution, passes, curing, unloading and inspection all sit inside the real cycle, and a quote that ignores them is estimating the machine rather than the job.

What belongs in the cost of a job?

Ink, media, time, labour and waste.

The published ink cost of roughly 0.80 to 1.20 US dollars per square metre is the starting point, and everything else is measured rather than assumed.

Two of those rows are usually missing from a quote. The first is waste, because a shop that quotes on a zero-reject assumption absorbs the cost of every reject. The second is overhead, because a shop that prices only direct cost covers its materials and not its existence. Both are recovered in the unit price or neither is recovered at all.

How should machine time be calculated?

From a timed batch, not a headline speed.

The published guidance is to time the complete representative batch including loading and inspection, because a headline speed does not describe the real cycle.

The published caution is specific on this point. The compact platform is quoted at up to 2,000 coins per hour and the page states that the figure describes one coin workflow rather than the platform in general, which is the honest way to publish a number and the reason it should not be used as a costing input.

The practical method is to time a real batch from the first part inspection to the last inspected piece, including one changeover, and to divide the usable hours in a shift by that figure. The result is not a machine specification; it is the throughput of the shop on that job, and it is the number a quote needs.

How is waste counted?

As material, ink and time together.

Setup, test prints, purge and rejects all consume resources, and the published ink cost and material yield both give a way to put a number on them.

Three sources of waste belong in the calculation. The setup, which includes the sample print and any test pieces produced before the run is released. The rejects, which the published inspection discipline is designed to catch early rather than late. And the layout waste, which is the material left on the sheet after the parts are cut, and which the published nesting guidance addresses directly.

The published ink cost figure makes the first two measurable: a print that consumes ink at a known rate per square metre turns a lost part into a cost rather than a feeling. The published yield thinking does the same for the sheet, because a layout that recovers one more part per sheet changes the media cost of every unit in the order.

What should a quote actually say?

Quantity, material, layers, finish and delivery.

The published artwork and process requirements describe what changes the price, and a quote that names them avoids the renegotiation that follows an assumption.

The published enquiry and approval lists for this range give a ready template. State the substrate and its finish, the ink layers including white and varnish, the artwork version, the finishing and converting steps, the quantity, the packing and the delivery term. Those are exactly the fields that change the cost, so naming them makes the quote a specification rather than a number.

Two other items belong in the same document. The tolerance or acceptance criterion, because a job that has to meet a durability test costs more than one that does not. And the revision policy, because a customer who changes the artwork after approval has changed the job, and the quote should say how that is handled rather than settling it in a conversation later.

How should small runs be priced?

With the setup charged once.

A short run carries the same setup as a long one, which is why the published approach separates the fixed preparation from the variable printing cost.

The arithmetic is simple and often ignored. A job of five panels and a job of fifty carry the same file preparation, the same fixture check and the same sample print. Spreading that fixed cost across five units produces a unit price far higher than across fifty, and a shop that quotes a small run at the same unit rate as a large one is buying the work.

The published guidance for short-run packaging makes the same point about where direct printing wins: the advantage is the absence of a plate, which is a fixed cost that a conventional process would spread across a long run. Where the quantity is small, the fixed cost is a larger share of the price, and the quote should reflect that rather than conceal it.

What margin protects the shop?

One that covers the remake.

The published acceptance discipline exists to prevent remakes, and a quote that assumes none leaves the shop carrying the cost when one happens.

The relevant number is the measured reject rate rather than a target one. A shop that knows its rate on a given material and job type can price the risk into the unit cost, and a shop that does not is pricing every job on the assumption that it will go perfectly. That assumption holds most of the time, which is exactly why the failure is a surprise when it arrives.

The published inspection and record discipline is what produces the number. The published process record covers the inspection result, and once a shop records rejects by reason, the rate becomes a figure that can be used in a quote rather than a variable that is hoped away. The acceptance guidance is covered in the article on inspection and acceptance records.

What records make quoting faster?

The timed batch and the reject rate.

The published process record, once it includes timing and reject data, becomes the basis for the next quote rather than a fresh estimate.

Four fields turn a job into a reference. The timed batch, so throughput is known. The yield, so the media cost is known. The reject rate and reasons, so waste is known. And the settings and material, so a similar job can be recognised as similar rather than treated as new.

The published ink cost and the published enquiry fields support the same structure from the other side, because they establish what the supplier publishes and what the customer must provide. Everything between those two points is shop data, and it is the shop data that makes a quote defensible. The published guidance on what to send with an enquiry is set out in the article on requesting a quote from a supplier, and the ink cost itself is covered in the guide to UV ink cost per square metre.

Where a customer requires durability testing, the cost of that work belongs in the quote as well, and the methods are the published ones: adhesion under ASTM D3359 and wear under ASTM D4060. Material and chemical obligations for the inks follow the applicable regulations (REACH), occupational guidance for the workshop is published by the relevant authority (HSE printing), colour practice is published by the International Color Consortium and Fogra, process guidance by PRINTING United Alliance, and trade and export requirements by trade.gov.

What the decision comes down to

A quote is a specification with a number attached. Cost the ink and the media from published and measured figures, time the whole cycle rather than the print, count the waste and the overhead, name what changes the price, and keep the timing and reject data so the next quote is arithmetic.

The published ink cost and platform figures for this range sit with the AJ1206 and AJ2513G/R pages, and the two adjacent guides are UV ink cost per square metre and how to request a printer quote.
