Transport documents ready for review: how the workflow works
Short answer
A legibility gate measures the brightness, contrast and sharpness of a photo of a transport document before it is read. When the image is unfit, the system records that no reading was attempted and asks for a new shot, in place of returning a full set of fields of unknown reliability. In our demonstrator, 5 of 7 image variants were stopped without calling the model. At Syntalith document reading automation costs from €3,000 net and pays back in 2.0 months.

image variants in the Syntalith demonstrator that the gate stopped before reading, without calling the model. This proves the mechanism works. We measure quality on the client's photos.

Is this photo readable in the first place?
A driver photographs a consignment note in the cab, in poor light and at an angle. The reading model returns a full set of fields anyway, because that is how it was built: some values are correct, some are guessed, and the employee cannot tell which are which. A legibility gate works earlier and stops an image that is not worth reading. The driver gets a request for a new photo while still at the unloading point. A week later, when the document reaches the office, a new shot is often impossible.
- 01MeasureBrightness, contrast and edge features of the image.
- 02DecisionThe image goes on to reading or is stopped.
- 03RecordWhen stopped, the result says „no reading attempted”, with the reason.
- 04RequestThe driver or the sender gets a request for a new shot.
- 05ReadingA legible image goes to OCR, and the fields sit next to the parts of the image they came from.
What our demonstrator shows
The operator chooses one of seven images, rotates the preview and points to a field on the document. The two legible examples let you download the saved fields, and the other five keep the state of a refused reading. The archive shows no model calls for the five blocked variants. The photos and synthetic values come from an earlier demonstrator, and the limits are set out in the source note. This is no measure of production quality and no result from a client rollout.
Legible
to reading
The fields go for checking next to the parts of the image.
Illegible
stopped
No reading attempted, with the reason: too dark, blurred, cut off.
Borderline
to a person
An image at the threshold goes to a manual reading.
What a legibility gate costs and when it pays back
- Today
- 1,000 photos × 3 min = 50 h (€1,745)
- With the system, a person checks the output in 15% of the time
- €262
- Model, 1 call per case, Claude Sonnet 5.5
- €7.34
- Cost of one case
- €1.75 today, €0.27 with the system
- Saving
- €1,476 a month
Payback of €3,000
2.0 months
The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 2,500 input tokens and 320 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.
The gate also lowers the model cost, because stopped images are never read, but the main gain is the absence of falsely complete data. According to Anthropic (2025), AI cuts the time of document tasks by an estimated 87%, but only when the result does not need every field checked again.
A first trial in the business
- Accepted and rejected photos from one process
- The number of false rejections the team can handle
- The point at which a manual reading is needed
- The time from the request for a new shot to receiving it
- The fields that most often need correcting after reading
A gate that is too strict shifts the work onto drivers, and one that is too lenient lets guessing through. That is why in the first month we count both kinds of error and move the threshold together with the person who receives the documents. We set the threshold on the client's photos, and the next steps are described in the posts about reading CMR documents and fine-tuning for transport documents. Google describes evaluating Document AI processors on a test set, which helps compare the variant with the gate against the one without it.

€1,745
a month for copying 1,000 documents by hand
Payback: 2 mo.
3 minutes to copy the fields from a document and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost about €0.007 per document: OCR in our system cost €1.17 for 181 files, and a separate read about €0.0008, converted at the NBP rate of 21 October 2026 and the ECB rate of 1.1205 USD per euro on 22 October 2026.
