# 16 × 20 Print

> Order one prepared 16 × 20 photographic print per quantity.

`print-16x20` revision `1` produces one 16 × 20 inch print for every quantity.
The paper choices are `lustre` (default), `pearl`, and `deep-matte`; read the
matching catalog `unit_costs` combination and its `pricing_status`.

| Required asset | Accepted ratio | Example prepared pixels |
| -------------- | -------------- | ----------------------- |
| `artwork`      | `4:5` or `5:4` | 4800 × 6000             |

```json theme={null}

  "product": { "id": "print-16x20", "revision": 1 },

The API validates the published orientation and metadata; it does not prescribe
a resolution policy or fabricate pixels. This standalone artwork role has
`rotation_policy: "allowed"`, so it accepts either listed orientation. Supply
prepared source media suitable for your intended physical output.
