Who must approve the data before printing?
The number of errors on printed materials is often not a design error, but a review process error.
Data must be reviewed by at least two people before printing: the owner of the data (finance department or data owner) and an independent reviewer, separate from the data creator, following the four-eyes principle. The person with authority appropriate to the sensitivity of the document must provide written approval on the final layout, not on a separate content file. The studio is only responsible for ensuring the printed data matches the version approved by the client, not for the correctness of the original numbers.
- executives sign off on the annual report and fundraising
- management signs off on less sensitive documents
- always require an independent reviewer
- the number creator is also the number approver
- approve verbally through unrecorded messages
When a printed document has incorrect numbers, the first question is always: who approved this version? If there is no clear answer, people start blaming each other and no one can fix the root cause. The number approval process is not complicated, but it needs the right people, in the right order, and it must leave a trace.
What is the four eyes principle and why is it mandatory?
The four-eyes principle (also known as maker-checker) stipulates that the person creating the number and the person approving it must be two different individuals. No one should have full authority over a critical step from start to finish.
The simple reason: the person creating the document has looked at it for too long; they will read what they think they typed, not what is actually on the page. An independent reviewer comes with fresh eyes and catches errors that the creator overlooked. This is a basic internal control principle, applicable to both small businesses and large corporations.
Who specifically needs to participate in approvals
There are three roles that need to be clearly distinguished before printing:
- Data source owner: finance department, sales department, or any unit that owns the original data. They confirm the numbers are accurate from a business perspective. This is a person you cannot overlook.
- The independent auditor: a person not involved in creating the numbers, who cross-checks each figure on the final layout with the original numbers. Could be someone in the same room but not the one who created those numbers.
- The final approver: the person with the authority appropriate to the sensitivity of the document, who signs and dates the proof before ordering printing.
The design studio is not responsible for the verification of figures in this list. The studio only ensures that the numbers on the printed version match those in the version you approved.
Approval depends on the type of document.
Less sensitive internal documents: capability statements, collaboration proposals, internal presentation materials. Approval from department management is sufficient. However, the two-person rule still applies, with no exceptions for "small" documents.
Common errors in the approval process
- The person who creates the numbers is also the one who approves them; no one cross-checks. This is the most common structural error.
- Approving verbally or via message without linking to a specific version. When there is an error, it is impossible to trace who approved which version.
- Approving a separate content file but not reviewing the final layout. The numbers may be misaligned when transferring the file to print format.
- Edit the last-minute numbers after approval without opening a new review round. The signed version and the printed version at this point are two different documents.
A single source of numerical standards. Every page should reference it instead of typing it out separately. Lock the numbers after approval. Any changes thereafter are a new round.

The viewpoint of Sinh Vũ
Sinh Vũ sends the final layout along with clear approval requests: who approves, which version, and on what date. After receiving written approval, the numbers are locked. If there are changes afterward, that constitutes a new round and is accounted for transparently.
This approach is not about creating procedures. The goal is for you to be able to trace accountability when needed, and for the studio not to bear the consequences of a figure it has no authority to confirm. Clarity from the start is better than disputes after thousands of copies have been printed.

Frequently asked questions
Can Sinh Vũ Studio check the data for me?
Sinh Vũ checks whether the numbers on the layout match the numbers sent and approved by the client. This is a technical presentation check. Sinh Vũ does not confirm the accuracy of those figures in terms of finance or operations, as that is the responsibility of the department that owns the data.
Is it okay if I review through messages or emails?
From a printing technical perspective, it is acceptable, but the risk lies in the message not being tied to a specific version. If there are disputes later, it will be difficult to determine which version you approved. It is best to sign off on the final layout PDF, clearly stating the date and the name of the approver.
Does a small document like a capability statement require a strict process?
You need an independent reviewer, regardless of the size of the document. The approval level can be flexible; a department manager is sufficient for standard capability profiles. However, the principle that the creator and the reviewer must be two different individuals is non-negotiable.
