Uncontrolled artwork is one of the most persistent root causes behind packaging recalls. Not a bad design: the wrong version of a good one. A superseded file gets sent to the printer, an old strength statement survives a revision, two people work on parallel copies and neither knows the other exists.

Graphic design for pharmaceutical packaging is therefore less about visual craft than about controlled process. The design has to be right, but more importantly the organisation has to be able to prove which file is the approved one, who approved it, against what source, and that the component sitting on the packing line is that file and nothing else.

This article sets out the artwork lifecycle, the technical file requirements, the checks that catch errors, and where things routinely go wrong.

The artwork lifecycle

A controlled artwork process runs through defined stages, each with a named owner and a documented output.

1. Brief. What is changing, why, which markets, which components, the deadline and the regulatory driver.
2. Copy source. Text is drawn from the approved Summary of Product Characteristics and patient information leaflet, not from the previous carton and not retyped. The approved source is the reference for every later check.
3. Design. The agency applies the copy to the approved cutter guide, within the structural and coding constraints already agreed.
4. Internal review. Marketing, supply chain and technical packaging check the design against the brief.
5. Regulatory review. Confirms the content matches the marketing authorisation and meets Part 13 and MHRA best practice expectations.
6. QA approval. The formal quality release of the artwork as a controlled document, with a version number.
7. Print supplier proof. A press proof on the specified substrate, checked against the approved master.
8. Packer verification. The contract packer checks the delivered component against the approved artwork at goods-in.
9. First-run approval. At line start, the printed component, the coding, the Braille and any barcode are verified before the run is released.

Skipping a stage does not save time. It moves the failure later, where correction costs more.

Version control is the whole game

There should be one controlled master per component per market, held in one place, with a version number that cannot be misread. "Carton_v3_final_FINAL2" is not a version number. A structured identifier tied to the component code, with an issue date and an approval record, is.

Three disciplines make this work. Only QA-approved artwork is released to a printer. Superseded versions are withdrawn or clearly marked obsolete, not left in a shared folder. Any change, however small, goes through change control and generates a new version with a documented reason.

Change control also has to reach downstream. The packer needs the new version, the changeover between old and new components needs planning, and someone has to decide what happens to the old cartons already in the warehouse.

Who signs what?

Ambiguity about sign-off is where errors get through. The roles need writing down.

The marketing authorisation holder owns the content. Regulatory affairs confirms it matches the authorisation. QA approves the artwork as a controlled document and owns the change control record. The design agency owns the accuracy of the file it supplies against the copy it was given. The print supplier owns conformance to the approved artwork. The contract packer owns incoming component verification, line set-up and the check that what is running is what was approved.

Technical file requirements

Most late-stage print problems trace back to a file that was never built correctly.

Vector artwork. Supply native vector files. Raster elements should be avoided for text and line work; where images are unavoidable, supply at adequate resolution for the print process rather than screen resolution.

Colour space and separations. Build in CMYK or specified spot colours, not RGB, and be explicit about which elements are spot and which are process. State Pantone references as numbers, remembering that a Pantone on coated board is not the same colour on an uncoated leaflet.

Minimum line weights and reverse-out text. Fine hairlines disappear and reversed-out text closes up on absorbent substrates. Set minimums for both and hold to them, particularly on leaflets.

Fonts. Outline them or supply the font files. A substituted font changes line breaks, which changes pagination, which can move text off a leaflet panel entirely.

Bleed, trim and overprint. Bleed to the agreed allowance, take trim and crease positions from the approved cutter guide, and check overprint settings. An element accidentally set to overprint can vanish on press.

Barcodes. Generate them as vector at the correct magnification, with quiet zones preserved and bar width reduction specified for the print process and substrate. This applies to linear codes and to the 2D DataMatrix used for serialised markets. A code that looks fine in a PDF can still fail ISO grading once printed on the real board.

The checks that actually catch errors

Automated text comparison. Compare the artwork text against the approved source file electronically rather than by eye. Human proofreading misses transposed digits and single-character differences reliably, and a wrong strength is a patient safety event.

Independent proofreading. Someone who did not write or lay out the copy reads it against the source, on the printed proof rather than the screen.

Braille verification. Check the translation is correct Unified English Braille, that the dot positions match the artwork, and that the embossing on the physical proof has clearance from creases, seams and varnish. Braille is checked physically, not on a PDF.

Barcode verification. Scan and grade the code on the printed component.

Line verification. At first-run approval the packer compares the component in front of them against the approved proof and the batch documentation, confirms coding position and legibility, and confirms the correct leaflet version is loaded.

Multi-market and translation management

Multi-market artwork multiplies risk. Each market has its own approved text, and translations must come from an approved translation source with a documented back-check.

For UK supply this now matters more than it used to. Joint EU/UK packs have not been permitted since 1 January 2025, so a UK pack needs its own carton with "UK Only" labelling, its own component code and its own artwork lineage. Treat it as a separate controlled item rather than a variant.

Where it goes wrong most often

The recurring failures are unglamorous: artwork released before regulatory sign-off because of a deadline, a leaflet updated without the carton being checked, a printer holding a superseded file, fonts substituted so pagination shifted, a barcode rebuilt at the wrong magnification, Braille approved on screen and never checked on board, old stock never reconciled after a change. Every one is a process failure rather than a design failure.

Key takeaways

• Copy must come from the approved SmPC and PIL, and every later check is made against that same controlled source.
• One controlled master per component per market, with unambiguous version numbering and superseded files withdrawn.
• File technicalities matter: vector artwork, correct colour space, outlined fonts, checked overprint, and barcodes built at the right magnification with quiet zones and bar width reduction specified.
• Automated text comparison, physical Braille checks and printed barcode grading catch what visual proofreading does not.
• Graphic design for pharmaceutical packaging only becomes safe when the packer verifies the delivered component against the approved proof at goods-in and at line start.

Talk to Central Pharma about artwork verification and line approval

The last two checks in the artwork lifecycle belong to the packer, and they decide whether an approved file becomes an approved pack. Central Pharma works alongside your design agency and regulatory team from an MHRA-licensed site in Bedford, with a dedicated QA team and three Qualified Persons: incoming verification of each component against the approved master, first-run approval covering coding, Braille and barcode grading, serialisation and anti-tamper application for export markets, and change control that reaches the stock already in the warehouse.
