Abstract
An ink jet printer having an array of nozzles from which ink droplets of adjustable volume are emitted further includes a mechanism adapted to individually adjust the volume of the emitted ink droplets. The mechanism has a first state wherein the emitted droplets of selected nozzles are of a predetermined small volume and a second state wherein the emitted droplets of selected nozzles are of a predetermined large volume. A controller selectively switches the mechanism between its first and its second states such that ink droplets of the predetermined large volume are not simultaneously emitted from adjacent ones of the nozzles.
Claims8
An ink jet printer comprising:
- a print head having an array of nozzles from which ink droplets of adjustable volume are emitted;
- a mechanism adapted to individually adjust the volume of the emitted ink droplets, said mechanism having a first state wherein the emitted droplets of selected nozzles are of a predetermined small volume and a second state wherein the emitted droplets of selected nozzles are of a predetermined large volume;
- and
- a controller adapted to selectively switch the mechanism between its first and its second states such that ink droplets of said predetermined large volume are not simultaneously emitted from adjacent ones of said nozzles.
An ink jet printer comprising:
- a print head having an array of nozzles from which streams of ink are emitted, said ink streams breaking up into droplets of adjustable volume moving along a path;
- a mechanism adapted to individually adjust the volume of the emitted ink droplets, said mechanism having a first state wherein the emitted droplets of selected nozzles are of a predetermined small volume and a second state wherein the emitted droplets of selected nozzles are of a predetermined large volume;
- and
- a controller adapted to selectively switch the mechanism between its first and its second states such that ink droplets of said predetermined large volume from adjacent ones of said nozzles do not simultaneously occur.
A method of inkjet printing using a print head having an array of nozzles from which ink droplets of adjustable volume are emitted;
- individually adjusting the volume of the emitted ink droplets such that the emitted droplets of selected nozzles are of predetermined small volume or of a predetermined large volume;
- and
- controlling the size of the ink droplets such that ink droplets of said predetermined large volume are not simultaneously emitted from adjacent ones of said nozzles.
