The A3 size sheet from Canson's Iris Vivaldi range, weighing 185 g/m² and featuring an intense, deep ultramarine blue, is produced using mass pigmentation, ensuring that the color remains identical on both sides of the paper and throughout its entire thickness. Made in France, it has a smooth finish and good resistance to cutting and folding, making it a classic choice for school projects, fine arts, interior design, and other creative applications that require a solid, uniform color.
