# Print Ads

> Print ad formats in AdCP cover newspaper, magazine, and trade publication advertising with physical dimensions, bleed, DPI, and CMYK color space requirements.

This guide covers how AdCP represents print advertising formats for newspapers, magazines, inserts, and trade publications.

## How print works in AdCP

Print uses the same building blocks as every other channel:

* **Collections** model publications (Vogue, Bergedorfer Zeitung, Ad Age)
* **Installments** model issues (March 2026 issue, Issue #47)
* **Installment deadlines** carry booking, cancellation, and material due dates
* **Creative formats** define physical dimensions, bleed, DPI, and file requirements
* **Placements** define positions (full page, half page, island, inside front cover)

No print-specific schemas are needed. The standard product model handles print when sellers declare physical units in their formats and deadlines on their installments.

## Print format characteristics

Print formats differ from digital in several ways:

* **Physical units** — dimensions in inches or centimeters, not pixels
* **DPI requirements** — minimum 300 DPI for standard print, 150 DPI for newspaper
* **Bleed** — extra image area beyond the trim that prevents white edges after cutting
* **Color space** — CMYK for full-color print, grayscale for B\&W
* **File formats** — press-ready PDF, TIFF, or EPS instead of JPG/PNG

### Insert/supplement

Multi-page inserts use a repeatable group for pages:

```json theme={null}
{
  "format_id": {
    "agent_url": "https://ads.publisher.example.com",
    "id": "insert_4page"
  },
  "name": "4-Page Insert",
  "renders": [{
    "role": "primary",
    "dimensions": {
      "width": 8.375,
      "height": 10.875,
      "unit": "inches"
    }
  }],
  "assets": [
    {
      "item_type": "repeatable_group",
      "asset_group_id": "pages",
      "required": true,
      "min_count": 4,
      "max_count": 4,
      "selection_mode": "sequential",
      "assets": [
        {
          "asset_id": "page",
          "asset_type": "image",
          "asset_role": "insert_page",
          "required": true,
          "requirements": {
            "min_width": 8.375,
            "max_width": 8.375,
            "min_height": 10.875,
            "max_height": 10.875,
            "unit": "inches",
            "min_dpi": 300,
            "bleed": { "uniform": 0.125 },
            "color_space": "cmyk",
            "formats": ["pdf"]
          }
        }
      ]
    }
  ]
}
```

## Publications and issues

A publication maps to a [collection](/dist/docs/3.1.0-rc.7/media-buy/product-discovery/collections-and-installments). Each issue maps to an installment with deadlines.

### The publication (collection)

```json theme={null}
{
  "collection_id": "bergedorfer_zeitung",
  "name": "Bergedorfer Zeitung",
  "kind": "publication",
  "description": "Regional daily newspaper for Hamburg-Bergedorf",
  "genre": ["IAB12"],
  "genre_taxonomy": "iab_content_3.0",
  "language": "de",
  "cadence": "daily",
  "status": "active",
  "deadline_policy": {
    "booking_lead_days": 4,
    "cancellation_lead_days": 3,
    "material_stages": [
      { "stage": "final", "lead_days": 2, "label": "Druckfertige PDF" }
    ],
    "business_days_only": true
  }
}
```

With `deadline_policy`, the collection declares lead-time rules once. Agents compute absolute deadlines from each installment's `scheduled_at`. A daily newspaper no longer needs to enumerate deadlines for every issue — the policy covers the common case, and individual installments can override when needed (e.g., holiday editions with earlier deadlines).

### An issue (installment with deadlines)

```json theme={null}
{
  "installment_id": "2026-03-28",
  "name": "Freitag, 28. März 2026",
  "scheduled_at": "2026-03-28T05:00:00+01:00",
  "status": "scheduled",
  "deadlines": {
    "booking_deadline": "2026-03-24T17:00:00+01:00",
    "cancellation_deadline": "2026-03-25T12:00:00+01:00",
    "material_deadlines": [
      {
        "stage": "draft",
        "due_at": "2026-03-25T17:00:00+01:00",
        "label": "Entwurf zur Prüfung"
      },
      {
        "stage": "final",
        "due_at": "2026-03-26T17:00:00+01:00",
        "label": "Druckfertige PDF mit Beschnitt (3mm)"
      }
    ]
  }
}
```

For a monthly magazine with longer lead times:

```json theme={null}
{
  "installment_id": "2026-05",
  "name": "Mai 2026",
  "season": "2026",

  "scheduled_at": "2026-05-01T00:00:00+02:00",
  "status": "scheduled",

    "cancellation_deadline": "2026-03-22T17:00:00+01:00",
    "material_deadlines": [
      {
        "stage": "draft",
        "due_at": "2026-03-29T17:00:00+01:00",
        "label": "Raw artwork for review and color proofing"
      },
      {
        "stage": "final",
        "due_at": "2026-04-05T17:00:00+02:00",
        "label": "Press-ready PDF/X-4, CMYK, 300 DPI, 3mm bleed"
      }
    ]
  }
}
```

## Print-specific image requirements

### Physical dimensions

Print formats declare dimensions in physical units (`inches` or `cm`) instead of pixels. The `unit` field on both format renders and image asset requirements controls interpretation:

```json theme={null}
{
  "dimensions": {
    "width": 8.375,
    "height": 10.875,
    "unit": "inches"
  }
}
```

When `unit` is absent, dimensions default to pixels (backward compatible with digital formats).

### Bleed

Bleed is the extra image area beyond the trim size. After printing, the page is cut to the trim dimensions — bleed ensures ink coverage extends to the edge with no white border.

Bleed can be specified per-side or uniformly:

```json theme={null}
"bleed": { "uniform": 0.125 }
```

```json theme={null}
"bleed": { "top": 0.125, "right": 0.125, "bottom": 0.25, "left": 0.125 }
```

Values use the same unit as the parent dimensions.

### Calculating total image dimensions

For a full-page magazine ad at 8.375 x 10.875 inches with 0.125" uniform bleed at 300 DPI:

1. **Total physical size**: (8.375 + 0.125 + 0.125) x (10.875 + 0.125 + 0.125) = 8.625 x 11.125 inches
2. **Pixel dimensions**: 8.625 x 300 = 2588 pixels wide, 11.125 x 300 = 3338 pixels tall
3. **Submitted image**: 2588 x 3338 px, CMYK, PDF or TIFF

For a European newspaper at 130 x 185 mm with 3 mm uniform bleed at 150 DPI:

1. **Total physical size**: (130 + 3 + 3) x (185 + 3 + 3) = 136 x 191 mm
2. **Convert to inches**: 136 / 25.4 = 5.354", 191 / 25.4 = 7.520"
3. **Pixel dimensions**: 5.354 x 150 = 803 px wide, 7.520 x 150 = 1128 px tall

### DPI

`min_dpi` specifies the minimum dots per inch for acceptable print quality:

| Use case                 | Typical min\_dpi |
| ------------------------ | ---------------- |
| Magazine (coated stock)  | 300              |
| Newspaper (uncoated)     | 150              |
| Large format / billboard | 72-150           |

### Color space

Print production requires CMYK color separation. Digital images in RGB must be converted before press. The `color_space` field declares what the publisher accepts:

* `cmyk` — standard for offset and digital print
* `rgb` — accepted when the publisher handles conversion
* `grayscale` — for black-and-white placements

### File formats

| Format | Use case                                    |
| ------ | ------------------------------------------- |
| `pdf`  | Press-ready composite (PDF/X-4 recommended) |
| `tiff` | Rasterized artwork, lossless                |
| `eps`  | Vector artwork with embedded fonts          |

### Safe area (trim margins)

Print production trims pages to their final size, and the cut can shift slightly. Critical content (headlines, logos, CTAs) placed too close to the trim edge risks being cut off.

Publishers declare trim margins using the standard [overlay](/dist/docs/3.1.0-rc.7/creative/formats#overlays) pattern — the same mechanism used for CTV player controls and DOOH bezels. Each overlay marks a zone where creative agents should avoid placing important content:

```json theme={null}
"overlays": [
  { "id": "safe_left", "description": "Left trim margin", "bounds": { "x": 0, "y": 0, "width": 6, "height": 185, "unit": "mm" } },
  { "id": "safe_right", "bounds": { "x": 124, "y": 0, "width": 6, "height": 185, "unit": "mm" } },
  { "id": "safe_top", "bounds": { "x": 0, "y": 0, "width": 130, "height": 6, "unit": "mm" } },
  { "id": "safe_bottom", "bounds": { "x": 0, "y": 179, "width": 130, "height": 6, "unit": "mm" } }
]
```

A 6mm margin is standard for European newspaper production. Overlay bounds support physical units (`mm`, `cm`, `inches`) alongside `px` and `fraction`, so publishers can express safe areas in whichever unit their prepress workflow uses.

## Deadlines beyond print

Installment deadlines are not print-specific. Any channel with advance material requirements uses the same pattern. See [collections and installments](/dist/docs/3.1.0-rc.7/media-buy/product-discovery/collections-and-installments) for deadlines on podcasts, influencer host reads, and live events.
