Which batch numbers and dates should appear in a packaging mockup?

Separate fixed artwork from production data

For an illustrative retail carton, the brand name and product description may belong to the fixed artwork while a batch code changes between production runs. Record which team supplies each variable field and how it will be applied. Do not ask the generator to invent a plausible expiry date to make the mockup feel realistic.

A placeholder that looks like a genuine date can survive into a public image or a printing proof. Use clearly identified sample data in concepts and inspect every view, including side panels that are easy to miss.

Create a variable-field register

Obtain category-specific requirements from the responsible experts. This article does not prescribe expiry, regulatory labeling or code formats.

Review the printing method separately

Ask the supplier how the variable information is applied and what space it needs. A generated mockup does not establish printer compatibility, legibility or resistance to handling. Preserve the approved technical requirements in the production artwork handoff.

Approve concepts and final files differently

Mark concept exports as samples where necessary and avoid publishing fictional production codes as actual pack evidence. Before printing, reconcile the variable-field register with the approved final process. Use panel reconciliation and sample approval for the broader release.

A placeholder caught at proofing

A fictional carton concept contains a realistic-looking sample date on its side panel. During supplier proof review, flag that field as a placeholder and ask the authorized production owner for the actual coding process. Inspect the front, back and side exports so the sample is not accidentally presented as real product information in marketing. Preserve the fixed artwork separately from changing data. The useful handoff identifies the field, owner and production treatment without inventing expiry rules or assuming that a generated raster code can be printed operationally.
