ABSTRACT:
An imaging inkjet cartridge system for an inkjet printing mechanism provides near photographic image quality, as well as crisp black text and line art. In a multi-pen carriage, typically for a tri-chamber full color (e.g. cyan, magenta and yellow) cartridge and a monochrome (e.g. black) cartridge, the monochrome cartridge may be replaced with an imaging inkjet cartridge. The full color cartridge carries full colorant concentrations of inks, while the imaging cartridge carries ink formulations having reduced colorant concentrations, such as cyan and magenta, with either a full or a reduced colorant concentration of black ink. The carriage may also carry all three cartridges (full color, black and imaging). Pens containing other color and concentration combinations may also be interchanged. A method is provided of retrofitting or upgrading an inkjet printing mechanism by replacing or interchanging cartridges, such as by replacing the monochrome cartridge with an imaging inkjet cartridge.
