Abstract:
A method of increasing the optical density of a printed image includes treating a first layer of deposited ink with a corona discharge. An apparatus for increasing the optical density of a printed image includes a print head for depositing a first layer of ink; and at least one electrode in proximity to the print head for treating the first layer of ink with a corona discharge.
