Packaging is the design discipline with the most external constraints. It has to survive printing, work under shop lighting at a distance, carry legally required information, fit a production line, and cost a defensible amount per unit. A studio that starts with aesthetics and meets those constraints later will produce work that is redrawn.
Settle the technical facts before the creative brief
Substrate, printing process, colour capability, how many colours you are paying for, varnishes and finishes, and the physical tolerances of the line that will fill it. These decide what is drawable. A design specified with more colours than the budget allows, or with fine detail the printing process cannot hold, becomes a compromise at artwork stage when the good options have gone. Get the print specification into the brief at the start.
Required information is not the studio's to arrange freely
Regulated categories carry mandatory content with rules about placement and legibility: food labelling requirements sit in 21 CFR part 101, and any environmental claim on a pack falls under the substantiation guidance in 16 CFR part 260, which is where recyclable, biodegradable and similar words get companies into trouble. Bring that content into the layout early, because it occupies real space and cannot be shrunk to fit a nicer composition.
Design for the shelf, not for the screen
Packaging is judged at a distance, under uneven lighting, beside competitors, often turned to an angle the designer never considered, and increasingly as a small thumbnail online. Test the design in those conditions: print it, put it on a shelf with the competition, photograph it small. A pack that is elegant at full size on a monitor and illegible at arm's length has failed at its actual job, and this is discovered cheaply or expensively.
What to require in the contract
Production ready artwork in the formats your printer needs, not just concept visuals, and clarity about who handles pre press and who is liable if something goes wrong at print. Ownership of the files and unrestricted right to use them. A named contact for the printer to query. And a physical proof approved before any volume run, because colour on a screen and colour on your substrate are different things and only one of them is what customers see.
Questions people ask about packaging design services
What should be settled before packaging design starts?
Substrate, printing process, number of colours, finishes and the physical tolerances of the filling line. Those decide what can be drawn, and discovering them at artwork stage forces compromises when the good options are gone.
What regulatory content affects the layout?
Mandatory information with placement and legibility rules: food labelling requirements at 21 CFR part 101, and any environmental claim under the substantiation guidance at 16 CFR part 260. It occupies real space and belongs in the layout early.
What should the contract require?
Production ready artwork in your printer's formats, clarity on who handles pre press and who is liable at print, ownership with unrestricted use, and a physical proof approved before any volume run.
