Product Specifications

When to Use

• Create a new DTFilm sweatshirt product on Printful using SOL'S 03574
• Upload full-color designs (gradients, photos, unlimited CMYK) to a sweatshirt
• Apply SKAPARA branding via DTFilm label placement
• Generate mockups for SOL'S 03574 DTFilm products
• Manage SOL'S 03574 DTFilm variant colors and sizes
• Update Supabase with product data and mockup images

DTFilm Technique — Key Facts

• Full CMYK color — unlimited colors, gradients, photographic content
• Smooth vinyl-like texture — distinct from DTG's soft-ink feel
• Process: Design printed to PET film -> adhesive powder -> heat-cured -> heat-pressed at 165C -> cold peel
• Works on polyester blends (unlike DTG which requires high cotton content)
• File types use _dtf suffix in Printful API: front_dtf, back_dtf, etc.
• 50+ washes durability

Placements & Canvas Sizes

All DTFilm placements at 150 DPI:

IMPORTANT: front_dtf and front_large_dtf are mutually exclusive. Same for back_dtf and back_large_dtf. Choose one size per side.

Recommended SKAPARA Setup

• front_dtf: Main design (1800x2400 @150dpi)
• back_dtf: SKAPARA wordmark or complementary design (1800x2400 @150dpi)
• label_inside_dtf: SKAPARA S mark (255x255 @150dpi) — only +0.95 EUR

Total extra cost: +5.25 (front) + 5.25 (back) + 0.95 (label) = +11.45 EUR

Base Costs (Production EUR)

Workflow: Create New DTFilm Product

Step 1: Upload Designs to Supabase Storage + Printful File Library

# 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 ${PRINTFUL_API_TOKEN}" \
  -H "X-PF-Store-Id: 17795695" \
  -H "Content-Type: application/json" \
  -H "User-Agent: POD-AI-Store/1.0" \
  -d '{
    "url": "'${PUBLIC_URL}'",
    "filename": "'${FILENAME}'"
  }'

Upload all placement assets:

1. Front DTFilm design (1800x2400 @150dpi) -> FRONT_FILE_ID
2. Back DTFilm design (1800x2400 @150dpi) -> BACK_FILE_ID
3. Label inside S mark (255x255 @150dpi) -> LABEL_FILE_ID

Step 2: Create Sync Product

const product = await pf('/store/products', {
  method: 'POST',
  body: JSON.stringify({
    sync_product: {
      name: 'Product Name — SOL\'S 03574 DTFilm',
      thumbnail: publicUrlFront,
    },
    sync_variants: variants.map(v => ({
      variant_id: v.variant_id, // From VARIANTS.md
      retail_price: PRICES[v.size],
      is_enabled: true,
      files: [
        { type: 'front_dtf', id: FRONT_FILE_ID },
        { type: 'back_dtf', id: BACK_FILE_ID },
        { type: 'label_inside_dtf', id: LABEL_FILE_ID },
      ],
    })),
  }),
});

Key points:

• variant_id is the catalog variant ID from VARIANTS.md (NOT a sync variant ID)
• files[].type uses DTFilm placement names with _dtf suffix
• Include ALL size variants for each color (XS through XXL = 6 variants per color)

Step 3: Set Variant Prices

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

Step 4: GPSR Compliance (MANDATORY for EU)

<p><strong>Manufacturer:</strong> Printful Inc., Gandijas Dambis 15, Riga, Latvia LV-1045</p>
<p><strong>Material:</strong> 80% organic cotton, 20% recycled polyester (SOL'S 03574)</p>
<p><strong>Print technique:</strong> DTFilm (DTFlex) — PET film heat transfer</p>
<p><strong>Care:</strong> Machine wash cold, inside out. Tumble dry low. Do not bleach. Do not iron directly on print.</p>
<p><strong>Compliance:</strong> OEKO-TEX Standard 100, REACH</p>

Step 5: Create Product in Supabase

await supabase.from('products').insert({
  id: crypto.randomUUID(),
  title: 'Product Name',
  description: 'Creative marketing description only.',
  category_id: 'SWEATSHIRT_CATEGORY_UUID',
  base_price_cents: 5995,
  compare_at_price_cents: 9995,
  currency: 'EUR',
  status: 'active',
  pod_provider: 'printful',
  provider_product_id: String(pfProductId),
  product_template_id: '506',
  translations: {
    es: { title: '...', description: '...' },
    de: { title: '...', description: '...' },
  },
  product_details: {
    brand: 'SKAPARA',
    model: 'SOL\'S 03574 Comet',
    material: '80% organic cotton, 20% recycled polyester',
    print_technique: 'DTFilm (DTFlex)',
    manufacturing_country: 'LV',
    safety_information: GPSR_HTML,
    care_instructions: 'Machine wash cold, inside out. Tumble dry low. Do not bleach. Do not iron directly on print.',
  },
});

Step 6: Create Product Variants in Supabase

for (const { color, hex, variantIds } of COLORS) {
  for (const [i, size] of SIZES.entries()) {
    await supabase.from('product_variants').insert({
      product_id: PRODUCT_UUID,
      title: `ProductName / ${color} / ${size}`,
      color,
      color_hex: hex,
      size,
      price_cents: PRICES_CENTS[size],
      is_enabled: true,
      is_available: true,
      external_variant_id: String(variantIds[i]),
    });
  }
}

Step 7: Generate Mockups

curl -X POST "https://api.printful.com/mockup-generator/create-task/506" \
  -H "Authorization: Bearer ${PRINTFUL_API_TOKEN}" \
  -H "X-PF-Store-Id: 17795695" \
  -H "Content-Type: application/json" \
  -H "User-Agent: POD-AI-Store/1.0" \
  -d '{
    "variant_ids": [VARIANT_ID],
    "format": "png",
    "width": 1000,
    "option_groups": ["Ghost"],
    "options": ["Front", "Back"],
    "files": [
      { "placement": "front_dtf", "image_url": "DESIGN_URL", "position": { "area_width": 1800, "area_height": 2400, "width": 1800, "height": 2400, "top": 0, "left": 0 } },
      { "placement": "back_dtf", "image_url": "BACK_URL", "position": { "area_width": 1800, "area_height": 2400, "width": 1800, "height": 2400, "top": 0, "left": 0 } }
    ]
  }'

Step 8: Upload Mockups to Supabase Storage

Mockup URLs expire ~24h. Always download and re-upload with cache-buster ?v=timestamp.

Branding Strategy — DTFilm

• label_inside_dtf: SKAPARA S mark (255x255) — cheapest placement at only +0.95 EUR
• back_dtf: SKAPARA wordmark white on dark garments (1800x2400)
• Alternative: Use front_dtf for main design, skip back for cost savings
• Color Notes:
  • Grey Melange: medium tone — both light and dark designs work
  • Red: dark-medium color — white/light designs preferred
  • Royal Blue: dark color — white/light designs only
  • White: light color — use dark/black designs ONLY
