# Printful AOP Minimalist Backpack Production Pipeline

Full production pipeline for SKAPARA AOP Minimalist Backpacks on Printful. This is a CUT-SEW product — the design is sublimated onto white polyester fabric before the backpack is assembled. Four independently printable panels allow for cohesive yet varied designs across the bag's surfaces.

For DTG-based apparel products, see the `printful-cc1717` or `printful-tshirt` skills instead.
For simpler AOP bags, see the `printful-aop-drawstring` skill.
For larger AOP bags, see the `printful-aop-duffle` or `printful-aop-utility-backpack` skills.

## AOP / CUT-SEW Technical Notes

**How CUT-SEW sublimation works:**
1. Your design is printed onto transfer paper using sublimation ink
2. The ink is heat-pressed onto flat white polyester fabric panels
3. The panels are then cut and sewn into the final backpack shape
4. Result: seamless, edge-to-edge print coverage on each panel

**Design requirements:**
- **DPI**: 150 (standard AOP resolution)
- **Fill mode**: `cover` — design fills the entire panel area
- **Format**: PNG, no transparency needed
- **Color mode**: sRGB (sublimation inks reproduce sRGB accurately)
- **Base fabric**: White only (sublimation requires white/light base)
- **Each panel is a SEPARATE design file** at exact canvas dimensions

**Color considerations:**
- Sublimation produces vibrant, saturated colors on polyester
- Very dark designs (near-black) may show slight variation at seams
- Neon/fluorescent colors will NOT reproduce accurately — use standard sRGB gamut
- White areas = no ink = shows the white base fabric

## Multi-Panel Design — 4 PANELS

This backpack has **4 placements** — each is a separate panel of the backpack that receives its own design file.

### Panel Layout & Design Strategy

| Panel | Canvas (px) | Physical Size | Design Approach |
|---|---|---|---|
| `front` | 2175 x 3075 | 14.5" x 20.5" | Main visible surface — hero design |
| `top` | 1950 x 1200 | 13.0" x 8.0" | Top flap — subtle branding or pattern continuation |
| `bottom` | 4200 x 1200 | 28.0" x 8.0" | Base panel (wide!) — pattern continuation or contrast |
| `pocket` | 4200 x 750 | 28.0" x 5.0" | Front pocket (wide, narrow) — accent or brand element |

**IMPORTANT DIMENSIONS:**
- `front` is tall/portrait — standard backpack front panel
- `top` is landscape — handle/zipper flap area
- `bottom` is VERY wide (28") — wraps around the bag base
- `pocket` is VERY wide (28") and narrow (5") — front pocket exterior

### Design Coherence

**GOLDEN RULE:** All 4 panels should feel like ONE cohesive design. Strategies:
- **Continuous pattern**: Same seamless repeat across all panels
- **Gradient flow**: Colors transition from top to front to bottom
- **Themed zones**: Front = hero graphic, top/bottom/pocket = supporting pattern
- **Brand integration**: SKAPARA elements woven into the all-over pattern

**BRANDING:** Since there are no label placements, incorporate SKAPARA branding directly into the panel designs. The `pocket` panel (wide, narrow, prominent) is ideal for a subtle wordmark integration.

## Workflow: Create New AOP Backpack Product

### Step 1: Design All Panels

Create 4 PNG files at exact canvas dimensions:

| File | Canvas (px) | Purpose |
|---|---|---|
| `backpack-front.png` | 2175 x 3075 | Main front panel design |
| `backpack-top.png` | 1950 x 1200 | Top flap design |
| `backpack-bottom.png` | 4200 x 1200 | Bottom base panel design |
| `backpack-pocket.png` | 4200 x 750 | Front pocket design |

### Step 2: Upload Designs to File Library

Upload each to Supabase Storage first, then POST to Printful File Library:

```bash
# Upload to Supabase Storage
curl -X POST "${SUPABASE_URL}/storage/v1/object/designs/uploads/${FILENAME}" \
  -H "Authorization: Bearer ${SUPABASE_SERVICE_KEY}" \
  -H "apikey: ${SUPABASE_SERVICE_KEY}" \
  -H "Content-Type: image/png" \
  -H "x-upsert: true" \
  --data-binary "@${LOCAL_FILE_PATH}"

PUBLIC_URL="${SUPABASE_URL}/storage/v1/object/public/designs/uploads/${FILENAME}"

# Upload to Printful File Library
curl -X POST "https://api.printful.com/files" \
  -H "Authorization: Bearer ${PRINTFUL_API_TOKEN}" \
  -H "X-PF-Store-Id: ${PRINTFUL_STORE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "'${PUBLIC_URL}'",
    "filename": "'${FILENAME}'"
  }'
```

Repeat for all 4 files:
1. Front → `FRONT_FILE_ID`
2. Top → `TOP_FILE_ID`
3. Bottom → `BOTTOM_FILE_ID`
4. Pocket → `POCKET_FILE_ID`

### Step 3: Create Sync Product

```bash
curl -X POST "https://api.printful.com/store/products" \
  -H "Authorization: Bearer ${PRINTFUL_API_TOKEN}" \
  -H "X-PF-Store-Id: ${PRINTFUL_STORE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
    "sync_product": {
      "name": "Product Name — AOP Backpack"
    },
    "sync_variants": [
      {
        "variant_id": 9063,
        "retail_price": "54.99",
        "files": [
          { "type": "front", "id": FRONT_FILE_ID },
          { "type": "top", "id": TOP_FILE_ID },
          { "type": "bottom", "id": BOTTOM_FILE_ID },
          { "type": "pocket", "id": POCKET_FILE_ID }
        ]
      }
    ]
  }'
```

**Key points:**
- `variant_id`: 9063 (single variant — one size, one color)
- `files[].type` maps to placement names: `"front"`, `"top"`, `"bottom"`, `"pocket"`
- Only 1 variant needed

### Step 4: Set Pricing

| Size | Base Cost (EUR) | Retail Price (EUR) | Margin |
|---|---|---|---|
| One size | 32.70 | 54.99 | 40.5% |

**Minimum retail (35% margin):** 50.31 EUR

**CRITICAL:** Set prices in Printful FIRST. The cron sync margin fixer overwrites prices if margin falls below 35%.

### Step 5: Generate Mockups

```bash
curl -X POST "https://api.printful.com/mockup-generator/create-task/279" \
  -H "Authorization: Bearer ${PRINTFUL_API_TOKEN}" \
  -H "X-PF-Store-Id: ${PRINTFUL_STORE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
    "variant_ids": [9063],
    "format": "png",
    "width": 1000,
    "files": [
      {
        "placement": "front",
        "image_url": "FRONT_PREVIEW_URL",
        "position": {
          "area_width": 2175, "area_height": 3075,
          "width": 2175, "height": 3075,
          "top": 0, "left": 0
        }
      },
      {
        "placement": "top",
        "image_url": "TOP_PREVIEW_URL",
        "position": {
          "area_width": 1950, "area_height": 1200,
          "width": 1950, "height": 1200,
          "top": 0, "left": 0
        }
      },
      {
        "placement": "bottom",
        "image_url": "BOTTOM_PREVIEW_URL",
        "position": {
          "area_width": 4200, "area_height": 1200,
          "width": 4200, "height": 1200,
          "top": 0, "left": 0
        }
      },
      {
        "placement": "pocket",
        "image_url": "POCKET_PREVIEW_URL",
        "position": {
          "area_width": 4200, "area_height": 750,
          "width": 4200, "height": 750,
          "top": 0, "left": 0
        }
      }
    ]
  }'
```

### Step 6: Download Mockups & Upload to Supabase Storage

```javascript
const storagePath = `designs/mockups/${productSlug}/${placement}.png`
const ts = Math.floor(Date.now() / 1000)
const publicUrl = `${SUPABASE_URL}/storage/v1/object/public/designs/${storagePath}?v=${ts}`
```

### Step 7: Update Supabase products Table

```javascript
const ts = Math.floor(Date.now() / 1000)

await supabase.from('products').upsert({
  id: productId,
  title: 'Product Name',
  description: 'Creative marketing description only. No specs here.',

    care_instructions: 'Spot clean or wipe with damp cloth. Do not machine wash. Do not bleach. Air dry.',
    print_technique: 'CUT-SEW (All-Over Sublimation)',
    manufacturing_country: 'EU',
    brand: 'SKAPARA',

    weight: '9 oz/yd2 (305 g/m2)',
    dimensions: 'H 16 1/8" x W 12 1/4" x D 3 7/8"',
    max_weight: '44 lbs (20 kg)'
  },
  status: 'active'
})

// Single variant
await supabase.from('product_variants').upsert({
  product_id: productId,
  color: 'White',
  color_hex: '#ffffff',
  size: 'One size',
  is_enabled: true,
  external_variant_id: '9063',
  image_url: `https://.../mockups/slug/front.png?v=${ts}`
})
```

## Known Issues & Gotchas

| Issue | Detail | Workaround |
|---|---|---|
| Seam alignment | AOP patterns may show misalignment at seams between panels | Use designs that tolerate seam breaks — avoid designs requiring precise cross-panel alignment |
| Bottom panel width | Bottom panel is 28" wide (4200px) — wraps around base | Design should work as a wrap or seamless repeat |
| Pocket panel ratio | Pocket is very wide (28") but narrow (5") — 5.6:1 aspect ratio | Use horizontal patterns or repeats — avoid tall/portrait elements |
| White base shows at edges | Dark designs may show white at seam allowances | Extend dark areas with bleed |
| Temporary mockup URLs | S3 URLs expire ~24h | Always download + re-upload to Supabase Storage |
| Single variant | Only one size/color — no variant toggles in ProductCard | ProductCard will show a single option |
| No label placement | No dedicated label area on this product | Incorporate SKAPARA branding into panel designs |
| Cache-busting | Browser/CDN cache images by URL | ALWAYS append `?v=timestamp` when overwriting Supabase Storage files |
