A proof is the document you sign to say this is what I want made. Everything after that point is expensive to change, because a die has been cut and plates have been made. Everything before it is free. That asymmetry is the entire reason proofs exist, and it is why an unread proof is the most costly thing in a packaging project.
What you are actually looking at
A digital proof usually arrives as a PDF in two views. The flat view shows the blank as it will be die cut, with cut lines, crease lines, glue areas and often the dimensions marked. The made-up view shows the same artwork wrapped onto a three dimensional model so you can see which panel faces the shopper. Both matter. Panels that look fine flat can end up upside down, mirrored or on the underside once the box is folded.
The checklist
- Read every word out loud, including the legal copy and the address. Spelling errors survive proofing more often than any other defect.
- Scan the barcode off the proof if your software allows it, and check the number against your own records.
- Check panel orientation on the made-up view. Front, back, top, bottom, and which way the artwork runs on the side panels.
- Confirm every dimension on the flat view, and confirm whether they are internal or external.
- Check that artwork crosses the creases the way you intend, since an image that runs over a fold will show a break.
- Confirm bleed and safety margins, so nothing important sits where the trim tolerance lives.
- Check the colour build. A brand colour set as a process build will not match the same colour set as a spot.
- Confirm the finish areas: where gloss, matte, foil or embossing land, and whether the varnish knocks out around a glue area.
What a proof cannot tell you
| Proof type | Confirms | Does not confirm |
|---|---|---|
| Digital PDF proof | Content, layout, dimensions, dieline, panel orientation | True colour on your stock, texture, fold behaviour, structural fit |
| Physical material in hand | Board feel, finish, how the box folds and closes, fit around the product | Nothing about the print run that follows it |
Colour is the honest limit. Your monitor is emitting light and the box is reflecting it, and no calibration makes those identical. If a brand colour has to be exact, specify it as a spot colour and say so on the quote rather than relying on a screen.
How the proof fits the schedule
Production time is counted from approval, not from the purchase order. Every day a proof sits unread is a day added to your delivery date, which matters most on a Rush lane where you are paying a premium of about 7 to 25% for speed. If several people have to sign off, get them lined up before the proof arrives.
What is included, and what it costs
A digital proof before anything prints is included on every order, alongside the die and plates, design support and US shipping. Minimum order is 100 boxes, from about $0.48 per unit at bulk volumes, confirmed on your written quote. Turnaround is quoted per product in three lanes, Rush (expedited production plus air freight), Standard (air) and Cost saver (sea), from about 7 business days, plus 2 to 5 for delivery, with specialty imported items running up to about 12 weeks.
If you want to see physical material before committing, say so during the quote conversation and we will work out what is practical for your job. Start at /quote/, and if you are still working out the artwork itself, what a dieline is covers the file you will be proofing.
