The printing process, step by step

Digital proof vs production print: what are you approving?

A printed proof does not automatically represent every detail of the finished notebook. Before approving it, confirm what it was made to check.

A digital proof may be a PDF on screen or a physical print made on a digital device. A properly prepared color-managed proof can also provide an agreed color reference. The name “digital proof” alone does not tell you which purpose applies.

Four kinds of proof or sample you may encounter

These are discussion categories, not a list of services included with every PUNDY order. One sample may serve more than one purpose.

PUNDY’s usual digital layout proof is a coated-paper print for checking text and layout, not final color. The final-material sample described above uses the specified production paper, printing method and matte lamination. Other ordering pages may use broader terms such as physical sample or custom proof sample; confirm the method and approval scope for your particular order. An existing stock sample is a reference for its own materials and workmanship, not proof of your custom artwork.

See the Ordering Process and FAQ for current sample terms.

The distinction is not “digital versus real printing.” It is what the sample represents and what the order will actually use.

Why can a proof and production print look different?

Check these conditions before deciding that the artwork needs changing:

• Output method: a digital device and an offset press can reproduce the same file differently.
• Paper: shade, coating and surface influence the appearance of ink. A proof may simulate a production paper rather than use it.
• Color settings: the target printing condition and output profiles affect color conversion.
• Fine detail: line width, screening, resolution and reproduction at the final size affect light grids and small text.
• Finishing: confirm whether the sample includes the final matte or gloss lamination. An unlaminated sample does not fully show the finished surface.
• Viewing conditions: compare the proof and production sample under the same lighting and at comparable viewing angles.

These differences are a reason to define the proof’s purpose—not a blanket explanation for any mismatch. If production differs from an agreed reference, compare the sample, file version and agreed conditions before deciding what needs correcting.

The grid is visible on my digital proof. Will it look the same in production?

Not necessarily. A light grid visible on one output device may look different on another, even when the file uses the same K percentage.

For example, C0 M0 Y0 K30 specifies a black-channel value in the file; it does not promise a particular visual darkness on every paper and printing system. Changing only the K value to match an unverified layout proof can therefore lead to the wrong adjustment.

Review the paper, line width, solid or dashed pattern, final size and printing method together. If subtle lines matter, ask which physical reference or test is appropriate for that job before approving the setting.

There is no universal rule that a digital proof will always look darker—or lighter—than the production print.

Can a digital proof be used to approve a Pantone color?

It depends on how the proof was produced and what has been agreed. A proofing device may simulate a spot color rather than print with the actual spot ink. Some colors or effects may fall outside its reproduction capabilities.

Provide the full Pantone reference, including C or U, and identify the production paper. Ask whether the proof verifies that color, merely approximates it, or needs another agreed reference. A displayed Pantone number does not mean the proof contains that ink.

Before signing off, record these five things

1. The file: version, date, page count and finished size.
2. The sample: PDF, digital print, color proof, press sheet or assembled sample.
3. The conditions: paper and output method; whether they match or simulate production.
4. The approval scope: which items are approved, which need changes and which remain unverified.
5. The production reference: the retained sample or file and any agreed color or finishing acceptance criteria.

For example, an artwork-only approval could read:

Approved for text, dates, page order and layout in file [version/date]. Grid darkness, brand color and final finishing remain subject to separate confirmation. Please confirm the reference and conditions for these items before production.

Use this wording only when it describes the actual agreement. A color proof and an assembled sample may have different approval scopes.

Questions buyers often ask

Does “physical sample” mean it was made on the production press?

No. “Physical” only means there is an object to inspect. Ask how it was made and which parts represent the final order.

If the proof uses the same paper, will the result be identical?

Not automatically. The output method, inks, settings and finishing also matter. Matching the paper removes one difference, not every difference.

Do I need a production-process sample for every order?

Not necessarily. The appropriate check depends on the job and what must be approved. Discuss the options and limitations before committing. Our FAQ explains sample terms; it does not mean every custom sample is produced on the final production press.

What should I send PUNDY if I am unsure?

Send the artwork and paper specification, identify the proof you are reviewing, and explain the concern: grid visibility, brand color, photographs or finishing. Ask which checks that proof supports and what still needs confirmation.

Agree what the proof means before approving it

A useful approval says more than “looks good.” It identifies the file, the sample and the items being accepted. That gives the buyer and production team the same reference.
