300 g or 270 g? Weigh it.
You cannot feel a 10% difference in board grammage. A precision scale can. PACKbid turns that into a routine every factory follows on every order.
The grammage proof
Cut a 10 × 10 cm square. That is exactly 0.01 m². Weigh it on a scale accurate to 0.01 g and multiply by 100: the result is the grammage in g/m².
| 300 | 3.00 g | Sample from 300 g/m² board |
|---|---|---|
| 270 | 2.70 g | Sample from 270 g/m² board |
Photos are taken in the app, time-stamped, with the order number label in frame.
Who proves what, and when
| Bid | Factory | Technical data sheet (TDS) of the paper or board |
|---|---|---|
| Start | Factory | Photo of the reel or pallet label used: grammage and lot number |
| Run | Factory | Three samples from start, middle and end: a 10 × 10 cm weighing photo plus one finished unit on the scale |
| Delivery | Buyer, optional | Your own measurement with the same method, used as evidence if you report an issue |
Tolerance and what happens outside it
The tolerance is the one stated in the TDS the factory uploaded with its bid. If a measured value falls outside it, an issue is opened automatically and payment stops.
- You choose: accept, accept with a discount, or return
- The factory’s reliability score drops
- Repeat cases lead to suspension
Artwork approval
- 01After award and payment, the factory uploads a PDF proof, numbered v1, v2…
- 02You approve it or ask for a revision
- 03The approved version is locked: date, user, file fingerprint
- 04No approval, no production
Who is responsible for what
Buyer
An error that is visible in the approved proof — a typo, a wrong barcode, a wrong colour reference.
Factory
A printed product that differs from the approved proof, or paper outside the TDS tolerance.
PACKbid decides disputes by comparing photos of the delivered goods with the approved proof and the recorded measurements. How to read a TDS →
