This white synthetic paper offers a unique alternative to traditional art papers. Pigments applied to the bright white sheets retain their true clarity and brilliance. Waterproof and stain-resistant, it is exceptionally strong, durable and will not buckle or tear. Originally used for offset printing, it also accommodates silkscreen, embossing, pen and ink, drawing, acrylic painting and aqueous techniques. As a watercolor paper, it has the advantage of being non-absorbent so colors lie on top of its surface producing brilliant, vibrant effects. Yupo requires no soaking, stretching, or taping flat. Best of all, it allows you to wipe off unwanted sections of your painting and start again with a fresh surface.
