Are you looking for a large, professional-grade blank for your sublimation projects? Look no further than the A3 size aluminum blank. This versatile panel is the ideal choice for creators who want to make a big impact.
What Are A3 Size Aluminum Blanks?
A3 aluminum blanks are sheets of aluminum prepared for sublimation printing. They have a special polymer coating that allows you to transfer vibrant, full-color designs onto them using a heat press.
The term “A3” refers to the international standard size. An A3 aluminum panel measures 297 x 420 mm (or approximately 11.7 x 16.5 inches). This large surface area gives you plenty of space to create stunning pieces of art, signage, or personalized gifts.
Why Choose A3 Aluminum Blanks?
There are many reasons to use A3 sublimation blanks:
- Large Format: The A3 size is perfect for big, detailed designs that smaller blanks can’t handle.
- Professional Look: The large, glossy surface gives your finished product a high-end, professional appearance.
- Durable: Aluminum is strong, scratch-resistant, and will not bend or warp like other materials.
- Vibrant Colors: The white polymer coating makes the colors of your design pop with amazing clarity.
Types and Specifications of A3 Blanks
Not all A3 aluminum blanks are the same. They come in different finishes and thicknesses to suit various projects. Here is a simple table to show the different types:
