The report knows the file, not the intention behind it.
“Preflight” is the name for a set of checks run before a file moves further through a print workflow. Depending on the job and the system used, it may flag page dimensions, missing resources, unexpected colour construction, image information, page count, trim or a technical setting that differs from the job instructions. That is useful evidence. It is not a statement that the document is commercially correct, legally cleared, visually approved or ready for every production route.
Think of the report as a prompt to ask a better question. If it finds an issue, someone needs to decide whether the file is wrong, the job instruction changed, or the proposed production route needs another conversation. If it finds nothing, someone still needs to decide whether the content and physical object are right.
Some checks are mechanical. Many of the important decisions are not.
Software can compare measurable conditions in a file with a rule set. It cannot reliably tell that a seasonal promotion expired last week, a translated paragraph belongs to the wrong market, a product photograph shows last year’s model, a required claim is missing, or a code now opens a retired web address. It cannot know which one of three folders labelled “final” was actually approved by the content owner.
That distinction becomes sharper with folds, book spines, card decks and packaging. A document may satisfy a generic page or bleed rule yet still need a project template, a component count, a fold check, a proof of the assembled object or a written decision about colour and finish. The physical job remains part of the review.
Pair the report with a decision record.
When a preflight report returns, make a short record rather than passing the PDF around in an email chain. Name the exact artwork file and version; list each issue or warning; say who owns the answer; record whether it was corrected, accepted as intentional or sent back for clarification; and note whether the change needs another technical check or a new proof. A designer can then see the correction, while a product owner can see the decision they still need to make.
This is especially useful when several people contribute to one catalogue, campaign, deck or box. The record creates a clear handover between the person working on the file and the person allowed to accept the content.
A changed file deserves the right kind of repeat check.
Do not assume that a small correction is isolated. Replacing a logo can alter a linked image; changing copy can reflow a folded panel; updating a barcode can alter its clear area; revising a page count can change a cover/spine template. The owner of the file should say what moved and whether the previous preflight result still applies. Where the approved proof or specification is affected, reopen that decision rather than treating the amended export as invisible.
A clear version name and a dated decision note are more reliable than a filename such as “final-final-2”. They help the team check that the report, proof comments and artwork really refer to the same object.
Check the job rules, then change the file.
Some automated tools can suggest or apply technical adjustments. That does not make every adjustment appropriate. A generic bleed extension, colour conversion, cutline change or image resampling can affect the artwork in a way the designer or content owner needs to see. Follow the job-specific instructions and keep control of the approved source file; do not treat an automated repair as a substitute for an agreed production specification.
Use preflight to shorten uncertainty, not to hide it.
For a first conversation, say whether the artwork is a working layout, a review PDF or a file you believe is ready for production. Bring the finished size, component or page count, template status, key colour/finish concerns, delivery need and a named approver. The production route, any file checking and any proof stage can then be scoped honestly instead of implied by a green status icon.
