ABSTRACT:
A variable optical density print system and method for continuous variation of the optical density among successive droplets expelled from the same nozzle, the print system comprising a fluid channel connected to a basis fluid supply and a fluid channel connected to a colorant concentrate fluid supply. Each fluid channel is in fluid communication with a single ink firing chamber. Appropriate amounts of basis fluid and colorant concentrate fluid are delivered to the firing chamber by briefly opening a microvalve positioned within each fluid channel. The fluids mix in the firing chamber and are then ejected as a single ink droplet which possesses a desired optical density.
