A saved PDF records artwork, but it does not preserve the appearance of the printed construction. A small retained-sample library helps distinguish a design change from a stock substitution or production variation. Its value depends on traceability: each physical specimen needs to point to the order, artwork and approval it represents rather than becoming another unmarked scrap in a drawer.
01
Define the purpose of the retained specimen
Decide whether a specimen represents approved appearance, placement, a finishing operation or a documented production event. Avery Dennison’s testing services distinguish different evaluation questions; your reference library should do the same. Do not mark an ordinary retained label as a certified durability sample. Its purpose may simply be to show what the brand accepted for a particular printed order.
02
Attach enough information to identify it
Record the supplier, order reference, artwork filename, stock and finish, plus the acceptance date and reviewer. Keep any specific appearance comments with the specimen. If the supplier uses a construction code, preserve it rather than replacing it with white matte. A future reviewer should be able to retrieve the appropriate digital proof and order without relying on the original packer’s memory.
03
Review the reference before relying on it
Ask the supplier how retained samples should be stored and whether age or storage affects the property you are comparing. Keep damaged or obsolete specimens clearly separated from current approved references. A sample can remain useful as historical evidence while becoming unsuitable as the sole present-day color target. Document when the reference is replaced and why, retaining the version relationship.
04
Set a reference retrieval routine
Before requesting a reprint, retrieve the current specimen and its file record as a pair. Confirm that both refer to the same accepted version, then check whether the proposed order changes material or finish. If the physical reference is damaged, tell the supplier rather than treating its altered appearance as a new target. Keep the library small and intentional, with a clear place for current references and a separate place for superseded jobs. A well-identified handful of samples is more useful than a large box of attractive but untraceable printing leftovers.
05
A practical example to adapt
For an illustrative coffee range, create one labeled sleeve for each accepted roast-label construction and order. Include a flat specimen and an identification photograph of its normal placement when appropriate. Keep the matching approved PDF reference on the sleeve record. Before the next order, retrieve the current accepted specimen and compare it with the supplier’s proposed construction. If the paper changes, request the appropriate review rather than silently moving the old approval forward. Once the new version is accepted, mark it current and retain the older specimen as historical. The system should make the approved reference obvious without requiring a large archive or an expensive cataloging application.
| Record | Decision to preserve |
|---|---|
| Purpose | State what the sample represents |
| Identity | Link order, file and construction |
| Storage | Follow supplier handling guidance |
| Status | Separate current and historical references |

Questions & answers
Is a retained sample a durability certificate?+
No. It is a traceable reference for its stated purpose. Formal performance claims need appropriate evidence and testing.
Should I discard every superseded specimen?+
Set a sensible retention policy for your business and supplier needs. Keep current and historical references distinct so an obsolete version cannot be mistaken for the accepted one.
