This giclée print delivers a vivid image with maximum color accuracy and exceptional resolution. The standard for museums and galleries around the world, giclée is a printing process where millions of ink droplets are “sprayed” onto high-quality paper. With the great degree of detail and smooth transitions of color gradients, giclée prints appear much more realistic than other reproduction prints. The high-quality paper (235 gsm) is acid free with a smooth surface.
