Be sure to note the type of paper used. Photographic inkjet paper is glossy and coated. This paper produces the very best images, and the paper is expensive. Smaller sizes are also available. In photographic quality printers the more ink colors handled, the better the tonal rendition.
Tonal rendition is the ability of the printer to accurately produce color ranges.
The minimum number of inks is 4. The 4 basic inks are black, cyan, magenta, and yellow. Some printers add two additional inks. This configuration means that when any one ink is consumed the cartridge must be replaced. Most inkjet printers have at least two cartridges - one for black and one for the color inks.
