Works by spraying and dyeing the page with color
Rated according to their resolution and color depth
Color depth is the range of colors that any given drop may represent
Resolution is measured in dpi, the number of dots per inch (horizontally or vertically) that a printer can place on a page. Sometimes the dpi is the same both horizontally and vertically, such as 1200 dpi. Other times, the horizontal and vertical dpi differ—as in1440x720 dpi.
Use a four-color process, CMYK (cyan, magenta, yellow, and black), to produce various colors. Sometimes the color black is excluded because it can be produced by mixing the other three colors.
Multiple drops of colors can also be placed on a single dot to produce more colors.
