# Label Studio — label designer

> EXTRACTOS EUM® Label Studio: design labels with dynamic templates (drag and drop), insert QR (Smart COA), anti-counterfeit CVV and barcode, and generate print batches. Already in production.

> **Label Studio** is the EXTRACTOS EUM® label designer. **It is already in production**: you design with
> templates, insert QR + CVV + barcode and generate print batches. Automatic compliance verification
> (NOM-051 seals and mandatory fields) is the layer being integrated on top.

## Two ready-made formats

* **Simple label** — for **finished product** (shelf).
* **Premium label** — for **raw material** (input identification) and presentations that require
  weight/category. See the [three label regimes](cumplimiento/etiquetado.md#antes-de-etiquetar-materia-prima-producto-terminado-o-ingrediente).

## Dynamic templates (drag and drop)

The **designer** lets you build your own label on a canvas in millimeters (at 300 dpi) with these
elements: **QR, barcode, field (COA data), text, image and logo**. You can:

* Save, **duplicate** and **version** templates.
* Mark templates as **public** (reusable) or start from an existing one.
* Validate the design before printing (the system checks that the fields and the canvas are correct).

## QR modes

Each label defines how its QR behaves:

| Mode | What the QR does |
| - | - |
| **global** | A single QR → the [Smart COA](smart-coa.md) page (lookup/tracking only). |
| **cvv** | Unique QR per piece → `/verify/<cvv>` (auto-verifies authenticity on scan). |
| **qr\_cvv** | QR → verification page with CVV entry (scratch-off format). |

## CVV (anti-counterfeit)

You generate unique **CVV** codes, **assign** them to a COA, and they are printed on each piece. They are
**publicly verified** ([how to verify](consumidores/verificar-producto.md)) and you can **revoke** a code (e.g.
due to a seizure).

## Print batches (print jobs)

You generate a **PDF with N labels** to print, you can **re-download** it and look up the **issued CVVs**
in each batch — for print traceability.

## What is being integrated

**Automatic compliance verification**: by reading the product's class and nutritional declaration from the SoT,
it calculates which **NOM-051 seals/legends** apply, verifies the **mandatory fields** and flags
**prohibited claims** ([Label anatomy](cumplimiento/etiquetado.md)).
