Handing Over a Decorated Bottle: The Proof and Sample Pack
When a decorated haircare bottle moves from approved sample to bulk, the only protection a brand has is the pack of objects and records that travels with it. If the approved proof, the master sample and the process record are not in that pack, a complaint that the bulk looks different from the sample becomes an argument rather than a discussion. Assembling the pack takes an afternoon; reconstructing it after a bad run takes a season.
Key takeaways
- The handover pack has three physical anchors: the approved artwork proof, the master decorated sample and the retained bulk sample.
- A master sample is only useful if it is sealed, dated and stored away from daylight and handling.
- The process record explains how the approved sample was made, which is what makes it repeatable rather than lucky.
- Acceptance criteria have to be written in terms a person on the line can check, such as colour against the master, registration and coverage.
- Both parties should sign one version of the standard, because two signed standards are effectively no standard at all.
Sample approval is usually treated as the end of the difficult part of decoration. In practice it is the beginning of the part where things quietly diverge, because the sample that was approved was made under trial conditions and the bulk will be made under production conditions.
The handover pack exists to make that transition checkable. It is not bureaucracy; it is the difference between a supplier saying the run matches the sample and both parties being able to verify it in ten minutes.
Here is what belongs in the pack, why each item exists, and where handovers most often fail.
What the pack contains, and why each item exists
The approved artwork proof defines the design. It should be the version actually used, signed and dated by both parties, with the proofing conditions recorded. Without it, the bulk can only be compared against somebody's memory of the design.
The master decorated sample defines the appearance. It is a physical unit from the approved trial or first-off run, sealed and labelled with the date and the process parameters under which it was produced. A master sample kept loose on a desk stops being a standard within a week.
The process record defines repeatability. Pre-treatment, cure parameters, line speed, ink or foil batch and the operator's inspection notes are what allow a decorator to reproduce a result rather than rediscover it. Where decoration sits inside a wider manufacturing scope, as it does with Xuelei Fragrance, the record usually connects to the batch documentation for the finished goods, which makes later enquiries much faster.
The retained bulk sample defines what was actually shipped. If a question arrives months later, the retained sample answers it directly, and it costs the supplier almost nothing to hold.
The handover pack, item by item
| Item | Purpose | Who keeps a copy | What fails without it |
|---|---|---|---|
| Signed artwork proof | Defines the approved design and version | Brand and decorator | No agreed reference for the artwork |
| Master decorated sample | Defines the approved appearance | Sealed at the decorator, duplicated for the brand | Colour and coverage arguments at delivery |
| Process parameters | Makes the approved result repeatable | Decorator, referenced in the order file | Every re-order is a fresh trial |
| Written acceptance criteria | Tells an inspector what pass and fail mean | Both parties | Inspection becomes a matter of opinion |
| First-off approval note | Records that production units were accepted | Both parties | Nothing links the standard to the run |
| Retained bulk sample | Answers later questions about the shipped batch | Decorator, on request by the brand | A complaint cannot be compared against anything |
Six items, one folder, one order number. The whole pack exists so that a disagreement about appearance can be resolved by looking rather than by negotiating.
Approving the first decorated units from the bulk
First-off approval is the moment the standard stops being theoretical. Units come off the production line, not the trial bench, and they are compared against the master sample under agreed lighting. Colour, registration, coverage, position on the bottle and the quality of the edges are the usual criteria.
The comparison should be recorded rather than remembered. A short note stating which units were inspected, against which master, by whom and on what date is enough, and it should be signed or confirmed in writing by both sides. Where the appearance is hard to describe, an agreed physical or laboratory test can be used instead of purely visual judgement; independent testing companies list packaging and print performance among their cosmetics and personal care testing services [1].
If units are accepted with a known deviation, say so explicitly in the note. An accepted deviation that is written down is a decision; the same deviation left unmentioned becomes a dispute.
The mistakes that make a handover worthless
The first is approving a sample that was not made on the production line, then treating the bulk output as if it should match it exactly. Trial equipment and production equipment differ, and the process parameters that reconciled them are the reason the process record matters.
The second is a master sample that is not sealed. A sample stored in a workshop, exposed to light and handled by several people, changes colour and surface. It is then used as a standard, and the comparison it produces is misleading in both directions.
The third is a standard that only exists verbally. Colour described as a little warmer or coverage described as slightly lighter cannot be inspected consistently, and two people applying the same words will reach different conclusions on the same unit.
The fourth is a change of substrate or ink without revisiting the approval. Substituting a bottle or a print input after the master sample was agreed invalidates the comparison, even when the substitution looks equivalent on paper. When a brand sources decoration and packaging as one package, as with Xuelei, substitutions are usually already within the same specification, which removes one common cause of drift.
Ask for the master sample to be duplicated. One copy stays sealed at the decorator and one stays with the brand, and neither is opened for routine inspection. The day the first copy is opened is the day it stops being a standard. the Xuelei brand publishes its manufacturing scope in the same order this checklist is built, which makes it easy to compare against your own pack.

Frequently asked questions
What is a master sample in bottle decoration?
It is a sealed, dated decorated unit that represents the approved appearance and is used as the reference for production. It should come from an approved trial or first-off run and be stored away from light and handling.
Can we use the trial sample as the master?
Only if the trial was run on production equipment with the final substrate and the intended parameters. Otherwise a sample from the first production run is a better master, because it reflects how the decoration will actually be applied.
Who should keep the retained bulk sample?
The decorator normally keeps it, because it is produced there and stored with the batch records. The brand should request it in writing and confirm how long it will be held, since it is the only physical answer to a later question about the shipped lot.
How long should a master sample be kept?
As long as the design is in production and for at least the shelf life of the goods made with it. If a re-order is placed a year later, the master sample is the fastest way to confirm that the standard has not drifted.
What if the decorator changes an ink or foil supplier?
Treat it as a change that requires a new comparison against the master sample, and record the decision. Even an equivalent-looking substitution can alter colour, coverage or durability, so the approval should be revisited rather than assumed.
