Printers with 6 cartridges

6

— six individual colours are used in an extended version of the CMYK colour scheme, where the base colours (cyan, magenta, yellow, black) are complemented by two secondary hues — most often pale cyan and pale magenta, but there are also models with orange and green. Anyway, the six-colour print format provides a higher colour accuracy than the standard CMYK scheme, this option is considered optimal for household photo printing (of course, adjusted for the rather substantial cost of such devices).
