Abstract:
1. A method of printing on a substrate using an ink jet printing assembly, said ink jet printing assembly having a first jetting assembly having a first ink orifice and a second ink orifice, a second jetting assembly separate from said first jetting assembly, said second jetting assembly having a third ink orifice, said third ink orifice being positioned between said first ink orifice and said second ink orifice in a cross substrate direction and a third jetting assembly separate from said first and second jetting assemblies, said third jetting assembly having a fourth ink orifice, said method comprising: driving said substrate in a driving direction, said substrate defining the cross substrate direction generally orthogonal to said driving direction; depositing an ink drop from each of said first ink orifice and said second ink orifice of said first jetting assembly in said cross substrate direction; depositing an ink drop from said third ink orifice of said second jetting assembly between said ink drops deposited from each of said first ink orifice and said second ink orifice; and alternating depositing an ink drop from each of said fourth ink orifice of said third jetting assembly and said first ink orifice of said first jetting assembly to form a generally consistent ink line in said driving direction.
