Use one release record, not an email chain
Artwork failures often start with two “final” files, an old dieline or an approval that does not say what was approved. Assign a unique SKU and artwork ID, revision, date and checksum or controlled-file link. Record the product, pack format, substrate, plant, print process, cylinder/plate/tool IDs, languages, destination and approvers. Supersede old files rather than renaming them informally.
Download the blank artwork release checklist (CSV) and retain it with the approved file and proof.
Four approvals that must not be confused
| Approval | Owner | What it confirms | What it does not prove |
|---|---|---|---|
| Content/regulatory | Brand or designated compliance owner | Identity, quantity, claims, instructions, warnings, origin and translations for the destination | Printability or barcode performance |
| Structural | Packaging/engineering owner | Correct dieline, panels, seams, gussets, folds, holes and machine direction | Legal wording or color match |
| Prepress | Converter/prepress with buyer approval | Separation, trapping, overprint, bleed, safe area, minimum features and plate/cylinder construction | Final production consistency |
| Production release | Named buyer/supplier QA owners | Representative printed pack matches the approved standard and required tests | Future lots unless change and process controls continue |
Dieline and geometry preflight
- Use the converter-issued dieline revision for the quoted material and machine.
- Separate cut, crease, seal, glue, weld, perforation, vent, zipper and print-safe layers.
- Show inside/outside and print-reading direction; mark reverse-print artwork.
- Keep mandatory copy, logos and codes outside seals, scores, gusset traps, handles and distorted corners.
- Define bleed and safe-area values from the supplier’s current process capability, not a generic design template.
- Check dimensions after assembly or forming, because flat artwork position can move on the finished pack.
- Confirm the repeat and web direction for rollstock; identify eye mark, unwind and splice constraints.
Text, translations and claims
The brand or importer should own required label statements and market claims. The print supplier checks whether they can be reproduced, but should not infer missing translations or rewrite regulated content without a documented request. For US food labels, FDA’s Food Labeling Guide explains that applicable statutes and regulations govern label statements and notes that requirements can change. Use the current regulation and qualified advice for the actual food and market.
| Content control | Release question |
|---|---|
| Product identity | Does the approved name match the product, grade/variety and destination terminology? |
| Net quantity/count | Are units, decimal marks, placement and responsible calculation approved? |
| Origin and responsible party | Are legal names and addresses consistent with commercial and import records? |
| Claims and marks | Is each certification, environmental, quality or performance claim supported and authorized for this SKU? |
| Languages | Was each translation reviewed in context, including punctuation, line breaks and mandatory terms? |
| Variable fields | Are lot, date, grower, packhouse, GTIN or other variable-data sources and owners defined? |
Color must be defined by process and substrate
Name spot colors or process builds and specify the measurement/visual reference, light source and approved tolerance when color is critical. A transparent film, kraft liner, white corrugated board and colored PP sheet provide different backgrounds. Reverse printing, lamination and a white underprint can change appearance. Identify whether the physical proof is made on the production substrate and process; do not treat a monitor or office printer as a production color standard.
Barcode data before graphics
- Identify the scanning application: retail POS, case, logistic unit, internal traceability or another workflow.
- Confirm the data owner: record the exact GTIN or other data, check digit, application identifiers and variable fields.
- Select the approved symbology: use the current GS1 application rules or the buyer’s system requirement.
- Set symbol dimensions: specify the allowed X-dimension/magnification and height for the application; do not scale by eye.
- Protect quiet zones: keep required clear space free of borders, text, seals, folds and print variation.
- Choose scannable colors: account for scanner illumination, ink opacity and substrate; screen appearance is insufficient.
- Place for the finished pack: check curvature, seam, gusset, handle, pallet orientation and likely scanner access.
- Verify representative output: use a calibrated verifier and the required method/aperture; record grade and failure parameters.
GS1’s barcode quality checklist calls out check digits, quiet zones, contrast, colors, construction, size, height, package obstruction, deterioration and position. Its 10-step guide links symbol size and color choices to the application and GS1 General Specifications.
Screen scan, phone scan and formal verification are different
A phone decoding a large code from a PDF proves little about the printed pack. Verification grades specified optical characteristics using a defined method and setup. It does not replace an operational scan test at the intended distance, speed, orientation and equipment. Use both when the application requires them, and retain the raw verifier report rather than writing only “barcode passed.”
Proof ladder
| Stage | Best use | Release limitation |
|---|---|---|
| Soft proof/PDF | Copy, language, layout, item/version and gross geometry | Not a production color, material, finish or barcode-grade proof. |
| Imposed/separated proof | Plate/cylinder separation, trapping, overprint, white plate and repeat | May not reproduce production ink/substrate interaction. |
| Contract or substrate proof | Closer color and material review under agreed conditions | Confirm how it differs from the production process. |
| Press/first-article sample | Real substrate, ink, machine direction, seams, forming and barcode verification | Still needs sampling and retained standard for later lots. |
| Production release | Lot-linked comparison to approved standard and defined measurements | Does not authorize unreviewed changes. |
Change-control triggers
Define which changes require content review, prepress review, new proof, barcode verification or route trial. Triggers can include substrate supplier or color, gauge, surface treatment, ink system, white plate, press/line, plate or cylinder remake, lamination, coating, bag dimensions, seam/gusset, barcode data, code size/location, artwork revision, legal entity, language, market or storage/use condition.
Release evidence pack
- Controlled artwork and dieline files with IDs, revisions and hash/link.
- Approval record listing scope and named owners.
- Font, linked image and separation/package report.
- Spot/process color targets and physical reference where required.
- Barcode data source, symbology, target size, location and current application specification.
- Representative verifier report and operational scan result when applicable.
- Signed physical sample or defined retained standard.
- Plate/cylinder/tool IDs, press/line, substrate and ink lot traceability.
- Deviation and reapproval record for any accepted exception.
Common failure modes
- Old dieline with current graphics.
- Two files both called final.
- Barcode rebuilt manually instead of generated from controlled data.
- Quiet zone crossed by a border, seal, fold or white-ink edge.
- Dark bars printed with a color build or process variation that reduces contrast.
- Code placed where the finished bag wrinkles or the carton curves.
- Reverse-print direction or white plate omitted.
- Translated copy approved outside the finished layout, creating truncation or wrong association.
- Digital proof treated as approval of production substrate, color and scan quality.
Frequently asked questions
If a barcode scans on screen, is it approved?
No. Verify the data and printed production-representative symbol, then test in the operating environment required by the buyer or application.
Who approves legal copy?
The brand/importer or its designated regulatory owner. The converter can flag feasibility and visible inconsistencies but should not silently assume ownership.
Is a PDF enough to start production?
Only if the agreed release workflow says which attributes the PDF approves and all other required physical, color, construction and barcode checks are complete.
