Packaging design look simple from outside. Pick a box, slap the logo on it, send to print. But anyone who has gone through a full production run know there is a hundred small decision in between, and getting any of them wrong can cost real money. Below are the mistakes that come up again and again, and what to do instead.
Guessing the Box Size Instead of Measuring
This is the number one problem. A box that is too big mean wasted material, higher shipping weight and a product that rattle around inside. Too small and your product simply dont fit, or the box bulge and splits at the seam.
Few things worth remembering about sizing:
- Box dimensions are always written as Length x Width x Depth
- Those numbers refer to the inside of the box, not the outside
- Length is the longer side of the opening, width the shorter one
- Depth is measured from the opening down to the base
- Add 1 to 3mm tolerance so your product slide in without force
Common retail carton sizes you will see used are 4″ x 4″ x 2″, 6″ x 4″ x 2″, 8″ x 6″ x 2″, 10″ x 8″ x 3″ and 12″ x 9″ x 2″. Mailer boxes often sit around 8″ x 6″ x 2″ and 12″ x 9″ x 4″. Rigid gift boxes are commonly 6″ x 4″ x 1.5″ or 8″ x 8″ x 2″. These are starting point only, not rules.
If you are unsure how to take the measurement properly, this guide to measuring box dimensions walk through it step by step with the right method for each box style.
Designing Without a Dieline
Designing your artwork on a flat rectangle and hoping it work on a 3D box is a recipe for disappointment. A dieline show you where every fold, cut, glue flap and tuck sit. Without one you will place your logo across a crease, or lose half your text inside the glue area.
Always request the dieline before your designer start. Most packaging suppliers list dielines free on request, and zeepackaging.com notes that their dieline templates come as editable PDF files that open directly in Adobe Illustrator, which is the usual working format for packaging artwork.
Ignoring Bleed and Safety Margin
Printing presses and die cutting machines have tolerance. They are accurate but not perfect.
- Add 1/8″ bleed on all side so no white edge appear after trimming
- Keep all important text and logo at least 1/8″ inside the trim line
- Never place a barcode near a fold or a corner
- Dark solid color across the whole panel will show every tiny misalignment, so use with care
Color Problems That Only Show Up After Printing
This one catch people out constantly. Your screen show RGB. The press prints CMYK. A bright blue or neon green that look amazing on your monitor can come out dull and muddy on board.
What to do:
- Build artwork in CMYK from the start, not convert at the end
- Use Pantone spot color if brand color accuracy really matter to you
- Remember kraft board shift every color warmer because of the brown base
- Ask for a printed sample if the color is central to your brand identity
Choosing the Wrong Board for the Job
A beautiful design on the wrong stock still fails. Lightweight cardstock in 12pt to 14pt work fine for a small cosmetic carton but will collapse under a heavy candle jar. Corrugated board handle shipping abuse, cardstock does not. Rigid greyboard look premium but cost significantly more and ship bulkier.
Match the board to the weight, the shelf life and how the box will travel.
Overloading the Panel
There is a strong temptation to put everything on the front. Logo, tagline, three certifications, a QR code, ingredient list and a lifestyle photo. The result is a panel where nothing stand out.
- One dominant element per panel, usually the logo
- Keep body text at 7pt minimum so it stay legible
- Give a QR code at least 0.8″ square with clear space around it
- Use the back and side panel, that is what they are for
Forgetting About the Real World
A box does not live on a screen. It sit on a shelf under fluorescent light, get stacked, gets handled with greasy fingers, and goes in a courier van.
Uncoated white board scuff and marks easily. Gloss lamination fingerprint badly. Soft touch feel lovely but shows oil from hands. Heavy ink coverage on a fold line will crack. None of these are deal breakers, but you should know about them before you commit to 5,000 unit.
Skipping the Proof
Every supplier offer a digital proof, usually a 3D mockup and a flat view. Looking at it for thirty second and clicking approve is how typos reach print. Read every word. Check the barcode scan. Confirm the dimension one last time. Once a job goes to setup, there is no going back without paying for it twice.
Getting packaging right is mostly about slowing down at the front end. The mistakes above all take minute to catch on a proof and week to fix after printing.
