My name is Matsumura , and I am the representative of PHOTOPRI , a large-format printing service with exhibition-quality printing.

What is large format printing?

Originally, this was a genre of printing that was often used for promotion in the advertising industry, and printing of sizes larger than A2 (420mm x 594mm) is often referred to as large-format printing.
