Abstract
The present invention includes as one embodiment a method for printing ink on a print media with a fluid ejection device of an inkjet printing mechanism, comprising generating first grid pattern data and second grid pattern data different from the first grid pattern data, sending the first grid pattern data to a first printing mechanism of the fluid ejection device and sending the second grid pattern data to a second printing mechanism of the fluid ejection device.
Claims31
A method for printing with an inkjet printer, comprising:
- generating first grid pattern data according to a first grid pattern and second grid pattern data according to a second grid pattern different from the first grid pattern;
- sending the first grid pattern data to a first printing mechanism of the inkjet printer;
- and
- sending the second grid pattern data to a second printing mechanism of the inkjet printer.
An inkjet printing mechanism, comprising:
- a fluid ejection device for printing ink with at least a first printing mechanism and a second printing mechanism;
- a fluid ejection control signal generator that generates first grid pattern data and second grid pattern data, wherein the second grid pattern is different from the first grid pattern, and wherein the first grid pattern data is sent to the first printing mechanism and the second grid pattern data is sent to the second printing mechanism.
An inkjet printing mechanism for printing ink on a print media with a fluid ejection device, comprising:
- means for sending rectangular grid pattern data to a black printing mechanism of the fluid ejection device;
- and
- means for sending hexagonal grid pattern data to a color printing mechanism of the fluid ejection device.
An inkjet printing apparatus for printing ink on a print media, comprising:
- a fluid ejection control signal generator that generates a control signal including rectangular and hexagonal grid pattern data and sends the rectangular grid pattern data to a black printing mechanisms, one for black text and one for black images;
- a signal processor that preprocesses position and timing signals associated with the hexagonal grid pattern data and sends it to the color printing mechanism;
- and
- a carriage motion control system for controlling the motion of a carriage holding the printhead.
A method using a computer-readable medium having computer-executable instructions for generating multiple grid pattern data for printing ink on a print media with an inkjet printhead of an inkjet printing arrangement, the method comprising:
- receiving position and timing signals of the inkjet printhead;
- subdividing the position and timing signals into multiple time divisions;
- and
- associating the subdivided time divisions with corresponding multiple grid patterns.
A method for printing with an inkjet printer, comprising:
- sending rectangular grid pattern data to a black printing mechanism of the inkjet printer;
- and
- sending hexagonal grid pattern data to a color printing mechanism of the inkjet printer.
