If you’re planning signage, exhibition displays, retail branding, or event backdrops, you’ve probably searched online for questions about sunboard printing. Sunboard is one of the most widely used materials in the printing industry today. It’s affordable, lightweight, easy to install, and delivers excellent print quality. But many business owners, marketing teams, and even designers still have doubts about pricing, durability, thickness and outdoor usage.

In this guide, we’ll answer the most common questions about sunboard printing, so you can make the right decision for your project.

1. What is the difference between sunboard and foam sheet?

A sunboard (also called PVC foam board) is a rigid sheet made from expanded PVC (polyvinyl chloride). It has a smooth surface and is commonly used for printing and signage.

A foam sheet can refer to different types of foam materials such as EVA foam, thermocol (polystyrene foam) or polyurethane foam. These are generally softer, lighter, and less rigid than sunboards.

So in short:

• Sunboard = hard, printable, signage material
• Foam sheet = soft, flexible, craft material

2. What is the price of 8x4 sunboard sheet?

The price of an 8x4 sunboard sheet usually depends on thickness and city. In India, it generally ranges between:

• ₹900 – ₹1,800 for 3mm to 5mm thickness
• Thicker boards (8mm–12mm) can cost more

Prices may vary depending on bulk order and quality grade.

3. What is another name for sun board?

Sunboard is also called:

• PVC Foam Board
• Foam PVC Sheet
• Forex Sheet (brand name commonly used)
• Expanded PVC Board
• All of these generally refer to the same material.

4. What is the use of sunboards?

Sunboards are widely used for:

• Promotional signage
• Exhibition panels
• Photo mounts
• Retail display boards
• Office branding
• Event backdrops

They are popular because they’re lightweight, affordable and easy to print on.

5. Is sunboard and PVC sheet the same?

Not exactly. Sunboard is a PVC foam board (lightweight and slightly soft inside). A regular PVC sheet is usually solid, heavier, and more rigid. So you can say sunboard is a type of PVC sheet — but not all PVC sheets are sunboards.

6. What is sunboard made of?

Sunboard is made from PVC (Polyvinyl Chloride) foam. It has a foam core structure that makes it:

• Lightweight
• Strong
• Smooth for printing

7. How does a sunboard work?

Sunboard doesn’t “work” like a machine. It works as a display material. You print graphics on it (usually vinyl pasted or direct UV printing), and then it acts as a sturdy base to hold and display your design. Think of it as a strong, printable platform for advertisements and branding.

8. Is Sunboard waterproof and OK for outdoors?

Yes, sunboard is waterproof because it’s made from PVC. But — and this is important 

• For short-term outdoor use, it works well.
• For long-term outdoor exposure (strong sun, heavy rain), it may bend or fade unless you use UV printing and proper mounting.

9. What machine is used to print on foam boards?

Usually, printing is done using:

• UV flatbed printing machines
• Eco-solvent printers (with vinyl pasting)

UV flatbed printers are the most common because they print directly onto the board surface.

10. Is sunboard heat resistant?

Sunboard can handle mild heat, but it is not fully heat resistant. If exposed to high temperatures for long periods, it can warp or bend. So it’s not ideal near high-heat areas.
