What does uncontrolled when printed mean?
Uncontrolled when printed is the note stamped on a drawing or document warning that a printed or downloaded copy has left the document control system, so nothing guarantees it is still the current revision. The controlled version is the one held in the system. Everything taken out of it, on paper or as a download, is a snapshot of one revision at one moment.

The stamp warns you about time.
A print is accurate at the second it leaves the printer, and the record keeps moving after that. The stamp is there because nothing on the paper reports the difference.
The wording sits where a reader already looks: along the sheet footer, inside a note field in the title block, or stamped across a PDF on export. It is a standing instruction rather than a disclaimer. Check the drawing number and the revision against the register, because the alternative is finding out on site that the sheet was superseded two revisions ago.
- 01Revisions supersede
A sheet can be revised the same afternoon it was printed, and the new revision retires the one in your hand.
- 02Paper does not update itself
Nothing on a printed sheet changes when the record moves on, so the print stays at the revision it was taken at.
- 03Downloads count as prints
A PDF saved to a laptop or forwarded by email left the system the same way paper does, and it ages the same way.
- 04Audits look for stale copies
A finding usually reads the same: work was done to a copy that was no longer current, and nothing on the copy said so.
The common form, set in the sheet footer or in a note field inside the title block.
The same warning in conditional form, used where the document is normally read on screen.
Names the artefact, which reads clearly on documents that are reissued as paper.
Adds the time, and usually prints beside the date and time the copy was taken.
They all mean the same thing. Pick one, apply it across the set, and readers stop having to work out whether the difference matters.
Prints stay useful. Give them a way back.
Nobody carries a laptop into a plant room, so prints keep earning their place. Four habits keep a printed set workable without anyone pretending it is current.
- Read the drawing number and revision off the sheet, then check the register before anyone builds, fabricates, or isolates to it.
- Issue formally on a transmittal, so the revision each recipient holds is recorded and holders of a superseded copy can be reissued.
- Print the date and time on the copy, so the next person to pick it up can see how old it is before they trust it.
- Print a QR code that resolves back to the live controlled document, so confirming a print costs a scan instead of a phone call.

How a transmittal records what was issuedLet the print answer its own question.
The stamp raises a question it cannot answer: is this still the current revision? Lunr answers it from the sheet itself, and keeps the controlled record behind it in document control.
Print a drawing with a QR code in its title block, and a scan resolves to the live controlled document.
The approved revision becomes the one the register serves, and the previous revision is marked superseded and kept, never deleted.
Issue a transmittal and it records the recipient, the date issued, and the revision of each document sent, so a reissue is a lookup.
Scan the QR in a printed title block from the iPhone or Android app to open the current revision from where you stand.
The print is still uncontrolled, and the stamp still belongs on it. What changes is how long it takes to find out where the sheet stands, and whether anyone bothers.

Questions about uncontrolled copies.
- What does uncontrolled when printed mean?
- It means the copy in your hand has left the document control system. The moment a sheet is printed or a PDF is downloaded, it stops receiving revisions, and nothing on the copy can tell you whether the record has moved on since. The stamp says the controlled version is the one held in the system, and the copy is a snapshot of one revision at one moment. Read the drawing number and revision off the sheet, then confirm against the register before anyone works to it.
- Is an uncontrolled copy still usable?
- Yes, as a reference. Print a sheet to mark it up, to walk a site, or to talk a detail through, and the stamp costs you nothing. The line sits at work that depends on the revision being current: building, fabricating, isolating, or committing money. For that, confirm the revision against the register first, or read the controlled document on a screen.
- Who decides whether a copy is controlled?
- The document control process does, rather than the person holding the copy. A copy is controlled while the system governs it, with one version marked current, a recorded distribution, and a revision history behind it. Print it, download it, or forward it, and the system loses that hold, so the copy is uncontrolled whoever took it. Some organisations do issue numbered hard copies on a controlled-copy register and recall them when a revision is released, which keeps a print current only because a person has taken on the job of reissuing it.
- How does a QR code change this?
- It closes the gap between the paper and the record. Print a drawing with a QR code in its title block, and a scan resolves to the live controlled document, so anyone holding the sheet can see whether it is still the current revision. The print stays uncontrolled and the stamp still applies. What changes is the cost of checking, which drops from a phone call to a scan.
- Is uncontrolled if printed different from uncontrolled when printed?
- No. The wordings are interchangeable, and both say the same thing: once a document leaves the system as paper or a download, nothing keeps it current. You will also see uncontrolled copy when printed, printed copies are uncontrolled, and valid only at time of printing. Pick one wording, set it in the footer or the title block, and apply it across the whole set so readers never have to interpret it.
