4. Detailed Step-by-Step Guide to Designing Advertising Posters with Nano Banana Pro

After understanding the outstanding advantages of Nano Banana Pro, you are probably eager to know how to create professional advertising posters in just a few minutes. In reality, poster design has never been easier or faster. Simply follow the detailed steps below to create products that are visually appealing and exactly match your ideas.

4.1 Step 1: Define the Poster’s Goal and Prepare Content

Before designing, answer these important questions to determine direction:

What is the main purpose of the poster? (Promote products, increase brand awareness, introduce events…)

Who is your target audience?

What key message or value do you want to communicate?

What is the poster’s main color theme?

Clearly defining goals helps you write accurate prompts and minimizes revisions. Prepare the following elements:

Brand logo

Product or main character images

Brand-appropriate dominant colors

A striking headline

Supporting content: product benefits, contact information, highlighted values

Product note: if original colors must remain unchanged, specify clearly so AI will not alter them

Once all information is ready, creating detailed prompts becomes easier, and the final poster will match your expectations.

4.2 Step 2: Access the Nano Banana Pro Website

On your computer or smartphone, access Nano Banana Pro to begin designing. On the main interface:

Select the Tools section

Click Create Image

Nano Banana Pro’s intuitive interface makes it easy for anyone to use, even without professional design experience.

4.3 Step 3: Write a Detailed Prompt for AI

The prompt determines about 70% of poster success. A complete and detailed prompt helps AI understand your concept accurately, from style and layout to colors and product details. A standard prompt usually includes:

Design style: modern, minimalist, luxurious, youthful…

Desired layout: product placement, text placement, highlighted details

Color tone: main colors aligned with brand identity

Lighting: studio lighting, natural light, or special effects

Text: accurate Vietnamese, clear fonts, no spelling errors

Image format: optimized for 2K or 4K depending on needs

Specific example:
“Design an advertising poster for the Dreame L30S Ultra robot vacuum with a modern style and luxurious white-blue color scheme. Place the product at the center with soft studio light effects in the background. Vietnamese text must be sharp, modern, and error-free. Title: ‘Dreame L30S Ultra – Your Companion for Every Vietnamese Family’. Include: 11,000 Pa suction power, powerful Vormax system, high-speed motor, separate airflow and dust channels. Clean layout, emphasizing luxury, 2K resolution.”

The more detailed the prompt, the better AI understands and the closer the result will be to your expectations.

4.4 Step 4: Upload Product or Character Images

If your poster requires real-life visuals, upload products, characters, or event images:

Click the “+” button to select files from your device

Add special requirements:

“Keep original product colors”

“Do not distort logos or important visuals”

“Preserve the model’s facial features”

Nano Banana Pro will automatically adjust images to blend naturally into the poster layout. Once uploaded, click Send for AI to generate the poster.

4.5 Step 5: Review Results and Refine

Within seconds, you will receive a completed poster. Check carefully:

Spelling, text spacing, and font correctness

Balanced positioning of products and characters

Brand color consistency

If revisions are needed, you do not need to start over. Simply adjust the prompt, and AI will generate a refined version. Once satisfied, click the poster and choose Download to save it.
