What makes Giclée printing different?

While giclée printing may sound similar to how your inkjet printer works at home, some key differences exist. Giclée prints, by definition, must start with a high-resolution image. The resolution of an image will determine how many dots of color will be printed. The more drops of ink, the better the clarity and detail of the picture. All giclée prints are required to have a minimum resolution of 300 DPI or dots per inch.
Another factor determining a giclée print is the materials used to create it. Giclée prints must use pigment-based inks. These high-quality inks guarantee accurate colours in an array of spectral hues. To be considered a giclée print, the work must also be printed on specially treated lignin and acid-free paper. This paper is specially formulated for use with pigment-based inks and ensures the print’s longevity. Lastly, giclée prints must be printed on a professional wide-format inkjet printer. These professional printers can create the highest quality prints in sizes up to A0.

I personally approve all prints quality in comparison to the original piece of art with a signature.
