Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of increasing the optical density of a printed image comprising treating a first layer of deposited ink with a corona discharge generated by at least one electrode attached to a print head that is to move across a width of the substrate, wherein the at least one electrode is sized less than the width of the substrate. 2. The method of claim 1 , further comprising: treating selected portions of the substrate with the corona disch…
