Abstract
An ink jet ink formulated to substantially reduce or eliminate start-up problems when an ink jet apparatus is initially discharged. The ink comprises at least two fluid components. The components have been matched to provide an ink that substantially maintains its initial formulation despite evaporation of the components.
Claims36
In an ink jet ink, the improvement comprising an ink formulated to substantially reduce or eliminate start-up problems when an ink jet apparatus is initially discharged, said ink comprising at least two fluid components, said components having been matched with respect to either their vapor pressures, boiling points, or evaporation rates to provide an ink that substantially maintains its initial formulation despite evaporation of said components.
In an ink jet ink, the improvement comprising an ink having at least two fluid components that are formulated to provide either substantially similar vapor pressures, boiling points, or evaporation rates, wherein start-up problems are substantially reduced or eliminated when an ink jet utilizing said ink is initially discharged.
In a method of substantially eliminating or at least reducing the tendency of an ink jet apparatus to improperly discharge during initial start-up, the improvement comprising the step of formulating an ink for said ink jet apparatus wherein at least two of its fluid components are matched with respect to either their vapor pressures, boiling points, or evaporation rates.
In a method of formulating an ink for an ink jet apparatus that can substantially reduce or eliminate improper or defective initial discharge of said apparatus, the improvement comprising the step of matching at least two fluid components of said ink such that each component has either substantially similar vapor pressures, boiling points, or evaporation rates.
