Everyday inkjet printers use four inks – cyan, magenta, yellow and black. Photo printers typically use six, introducing extra ‘light cyan’ and ‘light magenta’ inks. The greater number of inks reduces the faint ‘dottiness’that ordinary printers can sometimes produce when printing photos.

Some more sophisticated models may use as many as eight or even nine inks. These are designed to extend the colour range, or ‘gamut’ that the printer can produce. These extra inks can improve the print quality, but they also make printers expensive and complexto maintain. However, advances in inkjet printing technology are allowing manufacturers to move back to simpler systems, and many ‘photo’ printers now produce superb print quality with just four inks.
