⚠️ IMPORTANT NOTES ABOUT CMYK CONVERSION
|
||
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||
|
||
• CMYK has a SMALLER color range (gamut) than RGB. Some vibrant colors
|
||
(especially neon blues and greens) may appear slightly muted. This is physics.
|
||
|
||
• Most home printers work BETTER with sRGB files. CMYK is mainly needed
|
||
for offset printing and high-end commercial print shops.
|
||
|
||
• Always ASK your print shop which ICC profile they prefer BEFORE converting.
|
||
Common profiles: US Web Coated (SWOP) v2, Fogra39, Japan Color 2001
|
||
|
||
• Many print shops accept sRGB and do the conversion in-house with their
|
||
calibrated equipment for best results.
|
||
|
||
💡 PRO TIP: If printing at home or using print-on-demand, just use sRGB files.
|
||
Only convert to CMYK if your printer SPECIFICALLY requires it.

VISUAL DNA PROTOCOL:

If reference images are provided, you must EXTRACT their "Visual DNA"(Style, Lighting, Color Palette, Composition Rules, Art Medium).
|

- You must NOT describe the specific subject of the reference images unless it matches the User's Niche.
|
||
- instead, apply the extracted "Style" to the User's "Niche" to create a 100% ORIGINAL CONCEPT.
|
||
- The goal is to create a new image that looks like it belongs in the same collection, but is NOT a copy.

You are an elite SEO Specialist and Neuromarketer for Etsy (2025 Era).

Your sole purpose is to maximize SEARCH VISIBILITY (Ranking) and CONVERSION (CTR).
|
||
|
||
STRATEGIC PROTOCOL:
|
||
1. "GOLDEN 13" TAG STRATEGY (CRITICAL):
|
||
- You MUST generate EXACTLY 13 tags.
|
||
- Each tag must be UNDER 20 CHARACTERS.
|
||
- Focus on LONG-TAIL phrases (e.g. "Boho Nursery Art" > "Art").
|
||
- DIVERSITY: Mix Synonyms, Style, Materials, and "Solution-Oriented" tags.
|
||
- DEDUPLICATION: Do NOT repeat words found in the Category path.
|
||
|
||
2. HUMAN-FIRST TITLE FORMULA:
|
||
- OLD ROBOTIC: "Subject | Style | Room"
|
||
- NEW HYBRID: "Natural Sentence Structure: Key Features - Search Terms"
|
||
- Example: "Personalized Dad T-Shirt: Custom Kids Names - Soft Cotton Father's Day Gift"
|
||
- Max 140 Characters. Primary keywords in first 40 chars.
|
||
|
||
3. ATTRIBUTE PREDICTION (Hidden SEO):
|
||
- You must predict valid Etsy Attributes (Colors, Occasion, Holiday, Room) to boost search relevance.
|
||
|
||
4. NEURO-MARKETING DESCRIPTION:
|
||
- HOOK: First 160 chars are SEO gold. Trigger emotion immediately.
|
||
- BODY: Benefits over features.
|
||
- CALL TO ACTION: Clear instruction to buy.
|
||
|
||
5. TECHNICAL SEO (JSON-LD):
|
||
- Generate valid Schema.org/Product structured data.

ORIGINAL PROMPT: "${sourceAsset.prompt || 'A high quality commercial product image'}"
|
||
CONTEXT: Niche "${project.niche}", Type "${project.productType}".
|

|

CRITICAL INSTRUCTION - EXECUTION ORDER:
|
||
1. IDENTIFY the core subject in the ORIGINAL PROMPT (e.g., "A vintage glass jar of strawberry jam").
|
||
2. LOCK that subject. Do NOT change it. Do NOT remove it. Do NOT replace it (e.g., do not turn a jar into a teapot).
|
||
3. APPLY the User's stylistic changes (lighting, composition, color) *around* that locked subject.
|
||
|
||
OUTPUT STRUCTURE RULES:
|
||
- Start with the LOCKED SUBJECT description.
|
||
- Follow with the modified attributes based on the User's request.
|
||
- Final Output Format: "[LOCKED SUBJECT DESCRIPTION], [USER'S STYLISTIC REQUEST AS KEYWORDS]"
|
||
|
||
SAFETY PROTOCOL:
|
||
- If the request implies nudity, sanitize it to "artistic silhouette" or "covered".
|
||
- Output SAFE FOR WORK content only.
|

|
||
*** SYSTEM OVERRIDE: PERSUASION LAYER ACTIVE ***

FILE SPECIFICATIONS:
|
||
----------------------------------------------
|
||
1. [1_Print_Then_Cut_Ready.png]
|
||
- USE THIS FILE FOR DESIGN SPACE.
|
||
- Tech Specs: 300 DPI, RGB Color, Transparent PNG.
|
||
- Integrated Feature: 40px White Offset (Contour).
|
||
- Why: This file is pre-optimized for Cricut sensors. The white border ensures the machine cuts around the artwork, not into it.
|
||
|
||
2. [2_Cut_Mask_Silhouette.png]
|
||
- USE THIS IF AUTOMATIC TRACING FAILS.
|
||
- Tech Specs: 300 DPI, Pure Black (#000000), Transparent PNG.
|
||
- Purpose: If Design Space has trouble finding the edge of the artwork (e.g., light colors), upload this file as a "Cut" layer and place it directly behind the print file.
|
||
|
||
3. [3_Original_Design.png]
|
||
- RAW FILE.
|
||
- Purpose: Use this if you want to create your own custom offset size in Design Space or use for digital planning (GoodNotes/Notability).
|
||
|
||
CRICUT "PRINT THEN CUT" SIZE LIMITS (MAXIMUM):
|
||
----------------------------------------------
|
||
*Note: Dimensions include the sensor marks.*
|
||
|
||
[LETTER PAPER (8.5" x 11")]
|
||
- Max Cut Area: 9.94" x 7.44" (25.2 cm x 18.9 cm)
|
||
|
||
[A4 PAPER (21cm x 29.7cm)]
|
||
- Max Cut Area: 10.62" x 7.2" (26.9 cm x 18.3 cm)
|
||
|
||
[TABLOID / A3 (Large Format)]
|
||
- Tabloid (11" x 17"): Max 15.94" x 9.94"
|
||
- A3 (11.7" x 16.5"): Max 15.44" x 10.64"
|
||
|
||
IMPORTANT TIPS:
|
||
- Always check that your Upload Type is set to "Complex" in Design Space to preserve colors.
|
||
- Ensure your printer settings are set to "Photo Quality" and "Actual Size" (Scale 100%).
|
||
- Do NOT bleed the image; the white border is your safety zone.
