Abstract
A method of printing with coffee-based ink comprises providing a thermal ink-jet cartridge having a quantity of a coffee-based ink disposed within; receiving optical density data from a user via a touch-screen computerized interface, where the data describes an optical density of the coffee-based ink present within an ink-jet pod; and computing a customized droplet-size for the coffee-based ink in its current state within the thermal ink-jet cartridge. A suitable printing apparatus can include coffee-based ink in a cartridge, an image-processing system, an image processing module for determining, inter alia, droplet size and missing/defective nozzles, and a nozzle-compensation module. Suitable ink formulations are human-edible and aqueous.
