Abstract
A printing apparatus comprises a printhead and a controller. The printhead includes dies, each die comprising rows of nozzles, wherein, in an overlapping region, the rows of nozzles of two dies overlap in a first direction, in which a relative movement between the printhead and a print medium takes place during operation of the printing apparatus. The controller is to apply a first weaving mask to a first row of nozzles of a first die and a second weaving mask to a second row of nozzles of the first die, the second weaving mask being different from the first weaving mask, the weaving masks defining, independent of print data, which of the nozzles of the corresponding row are to be used for printing in the overlapping region.
Claims16
A printing apparatus comprising:
- a printhead including dies, each die comprising rows of nozzles, wherein, in an overlapping region, the rows of nozzles of two dies overlap in a first direction, in which a relative movement between the printhead and a print medium takes place during operation of the printing apparatus;
- and
- a controller to:
- apply a first weaving mask to a first row of nozzles of a first die and a second weaving mask to a second row of nozzles of the first die, the second weaving mask being different from and complementary to the first weaving mask, the weaving masks defining, independent of print data, which of the nozzles of the corresponding row are to be used for printing in the overlapping region.
A method comprising:
- printing an image using a printhead including dies, each die comprising rows of nozzles, wherein, in an overlapping region, the rows of nozzles of two dies overlap in a first direction, in which a relative movement between the printhead and a print medium takes place, the printing comprising:
- applying a first weaving mask to a first row of nozzles of a first die;
- and
- applying a second weaving mask to a second row of nozzles of the first die,
- the second weaving mask being different from and complementary to the first weaving mask, the weaving masks defining independent of print data which of the nozzles of the corresponding row is to be used for printing in the overlapping region.
A non-transitory computer-readable storage medium including instructions that, when executed on a processor, cause the processor to:
- control a printing apparatus to print an image using a printhead including dies, each die comprising rows of nozzles, wherein, in an overlapping region, the rows of nozzles of two dies overlap in a first direction, in which a relative movement between the printhead and a print medium takes place during operation of the printing apparatus, the printing comprising:
- applying a first weaving mask to a first row of nozzles of a first die;
- and
- applying a second weaving mask to a second row of nozzles of the first die,
- the second weaving mask being different from and complementary to the first weaving mask, the weaving masks defining independent of print data which of the nozzles of the corresponding row is to be used for printing in the overlapping region.
