Define what the image can decide
Use a mockup to discuss shelf presence, visual hierarchy, and the feeling a package should convey. Before choosing a direction, name the product, buyer, sales setting, first format, and information the customer must find quickly. Keep generated wording and symbols out of the approval record; they may only be placeholders.
Agree on what the image is for and who can approve that stage. A realistic rendering can help a team choose a look, but it does not establish dimensions or print feasibility. Our packaging design field note explains why the package also has to work in the conditions where people buy and use it.
Start with the supplier’s dieline
Ask the actual printer or converter for its approved structural file, material, print method, finish options, and delivery specifications. Check the panels, folds, seams, glue areas, bleed, and safe zones before placing type or images. If the structure changes, update the artwork from the new approved revision; do not infer a manufacturable shape from the mockup.
Replace plausible details with approved assets
Rebuild the selected direction using controlled logo, type, images, and colors. Route product claims, ingredients, warnings, required marks, and other regulated copy to the responsible product or legal owner. Use an authorized barcode file and confirm its placement and verification requirements with the supplier. Generated microtext and barcode-like graphics are not final content.
The picture can inspire the package; the approved file has to make it.
Preflight against the real job
Keep one approved dieline revision and printer specification as the fixed reference. Review each candidate file at its intended size and substrate, record what differs, and name the owner of the next fix. Pass when content and technical checks hold; correct and retest a defined issue; reject a mockup feature the chosen production method cannot deliver.
| Review area | Mockup can suggest | Production decision |
|---|---|---|
| Structure | A convincing package shape and panel layout. | Fit the approved dieline, folds, trim, and glue areas; correct or reject invented construction. |
| Content | Visual hierarchy with provisional words and codes. | Use owner-approved copy and source barcode artwork; retest legibility and scan performance. |
| Artwork | Color, imagery, and finish direction on screen. | Check linked assets, fonts, effective resolution, separations, and the supplier’s finish limits. |
| Proof | A persuasive view of the intended result. | Compare the agreed proof with the approved file and job specification before release. |
Run the checks required by the vendor and inspect the appropriate proof, including the assembled form when construction matters. Adobe’s InDesign preflight guidance describes file checks such as missing links and font problems. Our AI artwork print-preflight checklist covers the next handoff decision.
Release one controlled package system
Keep the approved file, dieline revision, proof, and signoff together. If the product has flavors, sizes, or future variants, define what stays consistent and which fields change. The Maeker’s Sausage package-design project shows a family of packages carrying a shared identity across distinct products; it is a portfolio example, not evidence of an AI workflow.
When to bring us in
Bring Left Hand Design in before structure and print specifications are locked if you need the concept shaped around them. Our package design services can help connect the visual direction, approved artwork, and supplier handoff for the products you plan to launch.
