The designer messages on Slack at 11 pm. “The printer rejected the file — missing bleed on three variants. I need a decision by 6 am: do we correct and resend, or wait for the client to confirm?” The project manager reads it on their phone. The project was approved two days ago. The delivery deadline is the day after tomorrow.
Nobody made a deliberate mistake. Nobody is at fault. And yet, within hours, at least four people who had other things to do will be pulled into this single message.
One hour of the designer’s time — why that’s the wrong measure
When a file comes back with technical corrections, the agency instinctively counts: “one hour of designer time.” That’s true — but it’s an incomplete measure. A technical file correction is only one of the processes triggered by a single technical error. The others run in parallel, involve different people and never show up in any time-tracking report.
The real cost of a correction is not the time it takes to fix the error. It’s the time pulled away from other work by everyone who had to get involved.
Who loses — a map of time lost in one correction round
Below: one technical file error — broken down into real time involvement by role in the agency.
- Designer: 1–2 hours. Identifying the error, correcting the source file, re-exporting, verifying technical parameters, sending the corrected version.
- Project Manager: 30–60 minutes. Reading and assessing the printer’s feedback, contacting the client if the correction requires their decision, re-briefing the designer, monitoring.
- Account Manager: 15–30 minutes. Explaining to the client why the deadline is shifting or why a question is being raised after approval. Managing expectations.
- Studio Manager / Traffic: 15 minutes. Updating the schedule, potentially re-booking a production slot with the supplier.
- Second review: 15–20 minutes. Someone has to check the corrected file before it goes out again. The most expensive mistake is sending an unchecked correction and entering a second round.
In total: between 2 hours 15 minutes and over 4 hours of agency time per technical correction round — spread across five people, all of whom are simultaneously working on other jobs. For a network campaign with multiple file variants, multiply proportionally.
Not every correction is the same problem
It’s worth distinguishing three situations that agencies often group under the single label “correction”. Each has different causes and requires a different response.
Technical errors — resolution below the required level, missing or insufficient bleed, RGB instead of CMYK, unembedded fonts, missing preview file. These are errors in file preparation. They are entirely preventable through knowledge of the technical specification and applying it before export. This article is about these.
Content errors — wrong logo variant, outdated price, a typo discovered after layout approval. Preventable, but dependent on the maturity of the agency’s internal review process — and on who approved what on the client side.
Scope changes — the client changes the concept, format or message after the approved mockup. This is not a correction — it’s a new brief or a change of decision. Different causes, different costs, a different conversation about responsibility. Conflating this category with the others is the fastest way to lose project profitability without a clear reason.
Error detected before printing vs error detected after printing
— the only measure that matters
With a technical error, the only variable that determines the real cost is the moment of detection. Not whether the error occurred — because in a certain proportion of files, technical errors happen even in well-run studios. Only when they come to light.
Error detected before printing. The producer verifies the file before starting production and reports the specification non-compliance. The agency receives this information while the material is still in the system — not on the press. The correction involves the designer and PM. The schedule may hold or shift by a few hours. The client does not need to know. The cost is low and stays internal.
Error detected after printing. The materials arrived by courier. Something is wrong. If the error is content-related or visual — the decision to reprint or accept the faulty material belongs to the client and involves a conversation nobody wants to have. If the error makes the material physically unusable — a reprint is unavoidable. The cost: material for disposal, new production on an urgent basis, new delivery, new installation date. The whole team knows. The client too.
A print producer who verifies the file before starting production does not fix the file on behalf of the agency and does not take responsibility for its content. They give the agency a window to respond at the moment when a response is still possible and inexpensive. That is exactly the difference that determines whether a correction stays an internal studio matter or reaches the client.
Summary
The real cost of a technical file correction is not measured in the designer’s hour. It is measured in the collective attention of everyone who should not have been part of that project — and in which side of the press the error came to light.
Technical file preparation, a production brief and pre-submission verification are three tools that operate at the same stage — and each of them reduces the probability of an error reaching the printer.

FAQ
Can the printer fix a technical error in the file on behalf of the agency?
No — and it shouldn’t. Responsibility for delivering a file that complies with the specification lies with the ordering party. The printer can verify key technical parameters before starting production and report whether the file meets the requirements — but the decision to correct it and the actual correction are the agency’s or designer’s responsibility.
How long does a typical technical file correction take in an agency?
The designer’s correction alone takes 1–2 hours. But on top of that come: client communication (if the correction requires their decision), re-briefing the designer, rescheduling, and a second review of the corrected file. In total, one round of technical corrections engages the agency for 2–4 hours, spread across several people simultaneously.
What is DTP verification and when does it happen?
DTP verification is a technical check of the file before production starts — resolution, bleed, colour mode, embedded fonts, presence of a preview file. It takes place after the order is accepted, before the file reaches the press. Its purpose is to detect errors that would stop production — it does not replace the ordering party’s responsibility to check content and layout.
How can we avoid a situation where a file comes back with technical corrections?
The shortest route is knowing the print producer’s technical specification and applying it before exporting the file. The LP specification is available free of charge on laboprint.eu. An internal studio checklist run before every external file submission also helps.
Does a technical error always stop production?
It depends on the type of error. Some — such as missing bleed or resolution below the required level — prevent production and the order is put on hold until a corrected file is submitted. Others may be passed to print at the client’s responsibility if the ordering party confirms awareness of the error. In every case, the decision lies with the agency — not the printer.
What happens if the error in the file comes to light after printing?
This is the most costly scenario. If the error is content-related or visual — the decision to reprint or accept the faulty material belongs to the client. If the error makes the material physically unusable — a reprint is unavoidable. In both cases, the costs of material, new production and delivery are borne by the ordering party.
