Digital or offset printing: compare the whole order before choosing the cheaper unit

A print method with a low running cost can become expensive when the order needs substantial setup, frequent artwork changes or quantities that will expire before use. Compare the total cost of producing and delivering the required usable copies. Keep quality, stock, color and finishing requirements fixed while making the comparison; a cheaper quote for a different finished product does not answer the customer's question.

The decision is specific to the presses, supplier quotes and production route available to the shop. There is no universal quantity at which offset becomes cheaper than digital. A crossover calculation is useful because it exposes the assumptions behind the recommendation, including the cost of make-ready, the running cost per copy and the expected number of copies that will remain usable.

NIST MEP's setup guidance treats the transition between good output from successive runs as the interval to improve. For printing, use the shop's complete make-ready record, including the steps required to release acceptable work, when comparing production routes.

Write a common specification covering finished size, page count, paper, color requirement, proof approval, binding or folding, packing, delivery locations and the quantity the customer must receive. Note whether variable information appears on individual copies. Record the approved artwork version and the point after which a change requires another proof or production setup.

Obtain quantities and prices at each stage of the route. Press sheets, printed copies and finished deliverable pieces can be different measures. If spoilage is included in the printer's quote, avoid adding a second allowance for the same loss. If it is excluded, state the assumption and ask production whether the proposed input quantity can reliably produce the required finished output.

For an outsourced route, include freight and any inspection or finishing that remains with the shop. For an internal route, distinguish the cost that accepting the job causes from the standing costs that must still be covered across all jobs. Use both views where needed: one to select a route and another to judge whether the selling price supports the business.

Assume two hypothetical routes can deliver an identical finished leaflet. Digital has $80 of setup and $0.34 of variable cost per usable copy. Offset has $650 of setup and $0.12 per usable copy. The offset setup premium is $570, while its running-cost saving is $0.22 per copy. Dividing $570 by $0.22 gives a crossover of about 2,591 copies.

At 2,000 copies, digital costs $760 and offset costs $890. At 5,000 copies, digital costs $1,780 and offset costs $1,250. These are illustrative production costs, not current supplier prices or recommended selling prices. They assume the same usable output, no additional revisions, comparable delivery and no difference in ancillary costs.

Retain the formula in the quote worksheet: crossover quantity equals the difference in setup costs divided by the difference in variable costs per usable copy. If the route with the higher setup also has the higher variable cost, there is no positive cost crossover under those assumptions. Its selection would need another reason, such as a required finish or available capacity.

A customer may request 5,000 copies because the unit cost looks attractive while expecting to use only 2,000 before a price or product detail changes. Ask for the actual consumption plan. Separate quantities committed for known events or locations from speculative future use. The unused balance still consumes printing cash, storage and disposal effort even if the original unit price is low.

In the example, printing 5,000 offset copies costs $1,250. If only 2,000 remain useful, the production cost per useful copy is $0.625. Printing 2,000 digital copies costs $760, or $0.38 per useful copy, before any later replenishment. The comparison should then include the expected cost and timing of the second order, with its revised artwork, instead of assuming either that it will definitely occur or that it has no setup cost.

Use scenarios when future consumption is uncertain. Show a low-use case, the customer's expected use and a high-use case. Preserve the original artwork and consumption assumptions with the chosen route. This gives the account manager a reasoned explanation when a later change makes the printed stock unusable.

Finishing can change the route economics. A small digital run that requires outsourced binding and two courier trips may cost more than a larger integrated route. Conversely, an offset quote with inexpensive press time may have a finishing queue that misses the delivery date. Confirm the complete route with the production owner before presenting a final promise.

Count split deliveries and storage releases explicitly. A customer who needs 1,000 copies at five locations has created a different packing and logistics job from a single 5,000-copy delivery. Add the avoidable labor and freight for the chosen route, and identify who pays for replacements if an address changes or the customer misses a delivery window.

If capacity is tight, compare routes using the resources each consumes. An internal press may be available while the cutter is fully committed. Outsourcing only the constrained finishing step can be a viable third option, but obtain a real quote and confirm handoff quality requirements. A theoretical saving disappears when the job needs unplanned rework at the interface.

After delivery, reconcile input sheets, accepted finished copies, spoiled copies, setup time, finishing hours and freight. Compare the actual route with the quote and record who approved any artwork change. Separate customer changes from estimating errors so the next quote reflects the right cause.

Review the remaining stock with the customer when the commercial arrangement includes storage or scheduled releases. An order can be financially complete while the shop still holds customer-owned copies, or while unused inventory remains the shop's responsibility. Keep those arrangements visible in the job record and ask the accountant to determine the appropriate ledger treatment under the agreement.

Save a short route decision with the accepted specification, crossover assumptions and reason for selection. Recalculate when supplier terms, paper availability, artwork or finishing requirements change. The next salesperson should be able to explain why this job used its chosen method without treating an old quantity threshold as a permanent pricing rule.
