Abstract
A multicolor ink jet printing method which includes the steps of moving a carriage is moved relative to a recording medium in a main scanning direction and a subscanning direction orthogonal to the main scanning direction, printing each color with a different group of nozzle heads mounted on the carriage, wherein at least one color is printed with a larger number of nozzle heads than the other colors, and printing the at least one color with a larger printing resolution in the main scanning direction than the other colors.
Claims14
A multicolor ink jet printing method which comprises:
- moving a carriage relative to a recording medium in a main scanning direction and in a subscanning direction orthogonal to the main scanning direction,
- printing each color with a different group of nozzle heads mounted on the carriage,
- printing at least one color with a larger number of nozzle heads than the other colors, and
- printing said at least one color with a larger printing resolution in the main scanning direction than the other colors.
A multicolor ink jet printer comprising:
- a carriage adapted to travel relative to a recording medium in a main scanning direction and a subscanning direction orthogonal to the main scanning direction, and
- a plurality of groups of nozzle heads mounted on the carriage, wherein each of the groups are assigned to different colors and at least one of the groups comprises a larger number of nozzle heads than the other groups, wherein means are provided for implementing a color print mode in which the printing resolution in the main scanning direction is larger for the color printed with said one group than for the other colors.
A multicolor ink jet printer comprising:
- a carriage adapted to travel relative to a recording medium in a main scanning direction and a subscanning direction orthogonal to the main scanning direction, and
- a plurality of groups of nozzle heads mounted on the carriage, wherein each of the groups are assigned to different colors, wherein at least one group comprises at least three nozzle heads and each of the other groups comprises at least two nozzle heads, the nozzle heads of all the groups being staggered in at least three lines perpendicular to the main scanning direction, such that the lines mutually overlap in the subscanning direction.
