Six ink cartridges
Question : Why do some colour printers have six ink cartridges and others only
Answer : Standard colour printing combines four separate inks — cyan,
magenta, yellow and black — to create a wide range of colours on the page. The
four-colour printing method is used in everything from home inkjet printers to
large industrial presses used to print magazines, posters and books.
Many printers made to print colour photographs now use six separate inks to
produce images, usually adding lighter versions of cyan and magenta to the
regular four colours. The two additional inks are intended to help create
photographs with richer, more precise colour than you could get with a
four-colour printer. Some printers now even use eight ink cartridges, adding
red and green to the mix.
When buying a printer, consider what kind of printing you are most likely
to be doing. Many four-colour printers produce good photos and colour
documents, and are less expensive — both initially and for replacement ink
cartridges — than printers intended for photo printing.
