Selectable mixing of inkjet ink components

摘要

An ink replenishment system for an inkjet printing mechanism has an ink reservoir that is removably receivable by the inkjet printing mechanism to deliver an ink composition to an inkjet printhead for printing. The ink reservoir contains a large volume of colorless ink vehicle and one or more smaller containers of colorant or other ink components separate from the vehicle. At the time of desired use, a user makes a selection which activates the selected colorant and/or other ink constituent to mix with the vehicle to produce the desired ink composition. This ink replenishment system may be used in a replaceable inkjet cartridge ink dispensing system, or in an off-axis ink dispensing system, and a method of accomplishing such ink replenishment is also provided.
