### **Translation of the Chinese Poster Design Guide (English Version)**

This is a comprehensive guide for the design of a **premium food promotion poster**, intended for **new product launches**, **online platform displays**, **brand promotion**, **social media posting**, and **restaurant single-item advertising**.

---

### **Core Reference Rule**

**Image A** is the user-uploaded main food reference image and serves as the **core visual basis** for this poster.

- **Must strictly preserve** the type of the dish, its **main appearance**, **overall structure**, **core plating style**, **main ingredient presentation**, **color tone**, and **realistic texture**.
- **Do not replace** this dish with another, **do not generate a different dish**, **do not change the plating logic**, or **alter the dish's authenticity**.
- **Can optimize** lighting, clarity, shadow layers, spatial sense, and **commercial photography quality**, **as long as the original dish remains recognizable**.
- The **focus is to retain the original dish's identity**, and **only enhance the poster packaging, layout design, and overall visual presentation**.

---

### **Overall Positioning**

This is **not a regular menu image**, nor a **simple food photography**, but a **comprehensive commercial promotional poster** that integrates:
- **Premium restaurant brand advertising**
- **Food main visual**
- **Ingredient explanation**
- **Product benefit information**
- **Price conversion area**

The **overall style** should present:
- **Premium**, **clean**, **modern**, **polished**, **appetizing**, **realistic**, and **professional food advertisement**.
- Suitable for **new product promotion**, **online delivery platform display**, **brand promotion**, **social media posting**, and **restaurant single-item advertising**.

---

### **Background and Overall Style**

- Use **soft warm beige**, **cream white**, and **light warm beige** as the **background**.
- The overall design is **clean and simple**, with **mild high-end paper texture** or **gentle studio lighting space feel**.
- The image should have **comfortable white space**, **balanced layout**, and **fresh visual appeal**.
- It should reflect a **modern restaurant brand feel**, **light luxury menu style**, and **high-quality commercial advertising**.
- **Do not use complex backgrounds**, **over-decorate**, **avoid cheap feel**, or **use cluttered colors that distract the subject**.

---

### **Layout Structure**

Use a **stable vertical 2:3 format** with **clear information zones**, **clear hierarchy**, and **natural reading flow**:

#### **1. Top Brand Area**
- Place a **simple brand logo / small icon** **centered at the top**.
- Below it is the **brand name**.
- Further below is the **brand slogan / tagline**.
- Optionally, add a **thin, elegant dividing line** or **short decorative line**.
- The overall style should be **simple, modern, and brand-identifiable**.

#### **2. Mid-Upper Title Area**
- Use a **large, bold title** to display **[Product Name]**.
- The title is **centered above the main dish**.
- Font should be **thick, eye-catching, modern**, with a **premium advertising feel**.
- Color suggestion: **dark coffee, dark brown-black, or near-black**.
- Optionally, add **small decorative lines, short dashes**, or **emphasis symbols** in the **main accent color**.
- The title must be **clear and impactful**, and one of the **first visual focal points**.

#### **3. Central Main Visual Area**
- **Image A** is the **core visual subject**.
- The **main dish** is placed **centered**, with a **large size**, **high visual weight**, and **dominant presence**.
- The food must have **high-quality commercial food photography quality**:
  - **Realistic**, **appetizing**, **clear**, **rich in detail**, and **visually enticing**.
- Retain the **original dish type** and **basic plating logic**, **only enhance** lighting, detail, layering, and **polished commercial feel**.
- Add **a few related garnishes** (e.g., vegetables, herbs, fruit slices, sauce) at the bottom or around the dish for **subtle decoration**, but **do not overshadow the main dish**.
- **Do not generate unattractive, unrealistic, cheap, or overly AI-like food effects**.

#### **4. Left Ingredient Information Area**
- Title: **"INGREDIENTS"** or **"Component Highlights"**.
- Vertically list **4–6 ingredient modules**.
- Each module includes:
  - **Real small ingredient image** (cleanly cut, commercial photography style, with **mild shadows**).
  - **Ingredient name**.
  - **A short, simple description**.
- Use **thin dashed arrows**, **curved arrows**, or **simple guide lines** to **connect with the main dish**.
- Information should be **short and clear**, **avoid long paragraphs**.
- The left section should be **neat, orderly**, and **not cluttered**.

#### **5. Right Product Benefit Area**
- Title: **"NUTRITIONAL BENEFITS" / "PRODUCT BENEFITS" / "Product Highlights"**.
- Use **simple, uniform circular icons** + **benefit title** + **a short description**.
- Vertically list **4–5 benefit modules**.
- Icon style should be **uniform, modern, and simple**, **avoid complex and flashy designs**.
- Benefits can focus on:
  - **High protein**, **rich in vitamins**, **energy replenishment**, **rich texture**, **light and refreshing**, **satiating**, **lightweight**, **real ingredients**, etc.
- Emphasize **commercial marketing benefits**, **avoid exaggerated medical claims or therapeutic language**.
- The right section should be **clear and readable**, **but not overshadow the central main dish**.

#### **6. Bottom Price & Conversion Area**
- Centered at the bottom with **"PRICE"** or **"价格"** as the title.
- Use **large, eye-catching font** for the **price**, placed on a **dark brush-stroke / textured background**.
- The **price must be clear and prominent**, with **accurate currency units**.
- Below the price: **add the price unit** (e.g., **"PER SERVING"** / **"每份"**).
- Further below: add a **modern, rounded-edge button**, with **[Button Text]** as the label.
- The button should be **simple**, **clickable**, and **commercially engaging**.
- The overall layout should form a **clear purchasing guide**, **but avoid looking like a low-end promotional flyer**.

#### **7. Bottom Localized Social Media Guidance Area**
- **Do not use** **"Follow Us"**.
- **Do not use** **Instagram, Facebook, TikTok**, or other **international social media platforms** unless explicitly requested.
- **Do not display** **"platform logo + platform name"** together.
- **Do not repeat** platform names.
- The bottom should only have a **simple three-tier structure**:
  1. A line of **Chinese guidance text** (e.g., **[Bottom Guidance Text]**).
  2. A row of **small-sized platform icons** (e.g., **Douyin, Xiaohongshu, Video Account, Official Account, Meituan, Dazhong Dianping**).
  3. A line of **Chinese search guidance** (e.g., **[Bottom Search Guidance]**).

- **Platform icons** should be **small-sized**, **uniform in style**, **simply arranged**, and can use **monochrome dark**, **low saturation**, or **simplified brand identity styles**.
- Icons are only for **bottom decoration**, **not too large**, **not eye-catching**, **not affecting the overall premium feel**.
- The **search guidance** should be **simple**, **clear**, **localized**, and **trustworthy**, similar to **the light ending information on a real Chinese restaurant poster**.

---

### **Color Control**

- **Overall background color**: **warm white, beige, cream white**, to create a **clean, premium, warm, and appetizing tone**.
- **Main text color**: **dark brown, dark coffee, or near-black**, to create a **high-contrast readability**.
- **Accent color**: **[Main Accent Color]**, used uniformly for **logo details, decorative lines, button elements, title small decorations, and local emphasis**.
- **Natural color of the food** must be the **core visual color source** of the image, **maintaining both unity and layering**, **avoiding gray or cheap feel**.

---

### **Texture Requirements**

  - **Sharp details**
  - **Rich colors**
  - **Realistic texture**
  - **Natural highlights**
  - **Believable shadows**
  - **Appetizing presentation**
  - **Polished commercial finish**

- The **overall poster** should look like a **premium restaurant brand would release**, **not a regular AI collage or low-end menu page**.

---

### **Text and Information Density**

- All **small text** should be **short, accurate, and clear**, **avoiding long paragraphs**.
- The **left ingredient section** and **right benefit section** should be **neat and not cluttered**.
