Short Answer
Approve a sample for the features it actually represents. A PDF artwork proof helps confirm text, artwork versions and layout. A physical digitally printed sample can help assess scale, content and the construction it uses, but may differ from the planned production material, printing or finish. A pre-production sample is useful only when its relationship to the final specification is clear.
Before approval, ask what is the same as the planned order, what has been substituted and what still needs confirmation. Record the file version, sample identifier and approval scope in writing. Approving artwork is not automatically approval of color, material, special finishes or the complete packed set.
This is a buyer’s guide to possible proofing methods. South Print’s sample options, charges and timing must be confirmed for the actual project.
Clarify What the Word Digital Means
Digital proof may mean a PDF viewed on a screen. Digital sample may mean a physical item made on a digital printing device. Ask whether you are receiving a file, a printed sheet or an assembled product.
Also distinguish a sample of an earlier job from a custom sample made with your artwork. A previous-job sample may help communicate material or finishing preferences, but cannot confirm your text, artwork placement or set contents.
| Item | Can check | Check next |
|---|---|---|
| PDF artwork proof | Copy, artwork version and layout against the agreed drawing | Physical color, material feel and fit |
| Physical digital print sample | Actual scale, content and represented construction | Differences in production print, stock and finishes |
| Unprinted structural dummy | Dimensions, opening and fit with the contents used | Printed appearance and surface finish |
| Pre-production sample | The specific production features documented for that sample | Any substitute process, material or omitted component |
These names are not a universal specification. Ask the supplier to describe the actual sample rather than assuming that the label determines what it proves.
PDF Proof: Approve the Correct Files and Content
Check every printed face, inside panel and back. Confirm spelling, contact details, image crop, orientation, design IDs and the relationship to the approved dieline. Read small text and check that important content stays within the agreed safe area.
A PDF can document dimensions and placement, but it cannot demonstrate how the finished card feels or whether a filled box closes. Record those as separate physical checks when they matter to the project.
For a mixed greeting card set, check every artwork version rather than only the first design. For a matching game, check the faces and their assigned common back. The memory game artwork guide explains how to organize that file package.
Physical Digital Sample: Ask Which Features Are Representative
A printed sample lets you inspect an object at its actual size. Its value depends on what it was made to demonstrate. Ask which paper or board was used, how it was printed and cut, which finishes were applied and whether assembly follows the proposed production method.
If the stock is a substitute, use the sample only for agreed checks that the substitution does not invalidate. For example, an approximate paper mock-up may communicate layout, while final stiffness, opacity or packed stack depth still need confirmation on the intended construction.
A digitally printed sample is not automatically unsuitable for color assessment, and it is not automatically a production color standard. Ask whether it is a controlled color proof for the intended printing condition or simply a product mock-up. Agree its role before comparing it with production.
Pre-Production Sample: Confirm the Scope Behind the Name
Do not assume that pre-production means every component was made on the final equipment. Ask which parts use the planned materials, print process, tooling, finish and assembly, and document exceptions.
For an important feature, request a representative check before approving that feature. If a sample shows a printed imitation of foil, it can help show placement but cannot demonstrate the actual foil appearance. If a box is hand assembled, confirm which aspects of the final construction it represents.
One sample also does not establish the quality of every future production unit. Agree the production checks separately from the sample reference.
Decide How Color Will Be Approved
A phone photo is useful for discussing layout or showing a visible issue, but should not be the sole reference for a color-critical approval. Display settings, capture conditions and lighting can affect the appearance.
Adobe explains that soft-proof reliability depends on the monitor, device profiles and ambient lighting. A color-managed simulation therefore needs suitable conditions; opening a PDF on an arbitrary screen is not the same workflow. See Adobe’s color-proofing guidance.
Tell the supplier which colors are critical and agree an appropriate physical reference or controlled proof, the stock and finish, viewing conditions and an acceptance method. Do not invent a numerical tolerance after the sample has been approved.
For a spot-color card back, confirm whether the sample uses the specified spot ink or a process-color simulation. The matching game specification guide explains why back consistency matters during face-down play.
Check Special Finishes and Packed Contents Separately
A flat printed proof does not show the tactile effect of embossing, the reflection of foil or the handling of a laminate. Identify whether each finish is actually present, simulated or omitted. Ask what sample or reference is appropriate for any finish that remains open.
Check a folded greeting card after the intended folding and finishing steps when approving its physical construction. Check a card deck as a complete stack when approving the box fit. A correct front image alone does not settle either question.
For a boxed assortment, verify the actual card quantities, envelope allocation and packing sequence. A box that fits a substitute stack does not necessarily fit the final finished contents. Use the greeting card allocation guide to prepare the component list.

Use a Written Approval Record
An approval should identify the object or file, what has passed, and the remaining work. Include:
- Project name, product version and artwork filenames with revisions.
- Sample identifier and the specification it was made against.
- Approved features such as text, size, material or packing arrangement.
- Substituted materials, simulated finishes and omitted components.
- Any required changes and which new proof or sample will close them.
- Whether production may proceed, and for which specifically agreed scope.
For example, a buyer could record: artwork version 03 approved for copy and layout; sample S02 reviewed for size only; intended board, foil and filled-box fit remain open; production release pending those confirmations. This illustrates limited approval, not a default manufacturing instruction.
If one sample confirms structure while another confirms color, identify both references and their separate purposes. Retain the agreed reference files and physical samples where applicable so later comparisons use the same basis.
Revisit Approval After a Change
Ask which approvals are affected when artwork, stock, finish, cutting or contents change. A spelling correction needs a revised file check. Changing board thickness may affect handling and box fit. Adding envelopes or an insert may affect the packed unit even if the main artwork stays the same.
The supplier and buyer should agree whether the change requires a new proof, a new sample or a documented check, together with its cost and schedule effect. There is no single sampling sequence suitable for every order.

Frequently Asked Questions
Is a PDF proof the same as a digitally printed sample?
No. A PDF proof is a file for checking specified artwork and layout details. A digitally printed sample is a physical print or object. Confirm the material, process and purpose of the physical sample before approving it.
Can a digital sample be used to approve production color?
Only when its role and limitations have been agreed. A controlled color proof and a general product mock-up are different tools. Confirm the intended printing condition, reference and acceptance method with the supplier.
Does pre-production sample mean everything matches bulk production?
Not automatically. Ask which materials, printing, tooling, finishes and assembly match the planned order, and record any substitutions or omitted components before approving the relevant features.
Can I approve foil or embossing from a flat printed image?
You can review the indicated placement, but a flat printed imitation does not demonstrate the actual reflective or tactile effect. Agree an appropriate physical reference or sample for the finish.
What should happen if the specification changes after approval?
Identify which approved features are affected and agree a revised proof, sample or documented check as needed. Record the new version and confirm cost, timing and production-release implications before proceeding.
