1. An inkjet recording system comprising:
- an inkjet recording head having a plurality of nozzles arranged along a first direction;
a moving mechanism for supporting said recording head and/or a recording medium and moving said recording head and said recording medium relatively to each other along a second direction not parallel to said first direction in a recording operation;
a controller for accepting image data for recording an image by allowing said nozzles of said recording head to discharge an ink and for controlling said recording head and said moving mechanism for recording said image on said recording medium; and
an image data converter for converting said image data, wherein said image is recorded by a nozzle combination of which nozzles are a part of said nozzles that said inkjet recording head has and which includes nozzles arranged in a string along said first direction, said image data converter converts said image data so as to shift a position of said nozzle combination along said first direction, and said controller accepts said converted image data and controls said recording head for recording said image with said position of said nozzle combination shifted along said first direction.

Abstract
A recording system includes a line head having a plurality of nozzles arranged in a Y direction, a LF motor for feeding a role sheet in an X direction, and a CR motor for shifting a set position of the line head sequentially. When the set position of the line head is shifted by a given distance in the Y direction, the recording system converts image data in such a manner that an image is shifted in an opposite direction by a distance equal to the given distance so that the same image is recorded in different positions of the nozzles.

12. An inkjet recording method comprising:
-
a recording step of moving an inkjet recording head having a plurality of nozzles arranged along a first direction and a recording medium relatively to each other along a second direction not parallel to said first direction and recording, on the basis of image data for recording a given image, said image on said recording medium by using said recording head by allowing said nozzles of said recording head to discharge an ink; and
an image data converting step of converting said image data, wherein said image is recorded by a nozzle combination of which nozzles are a part of said nozzles that said inkjet recording head has and which includes nozzles arranged in a string along said first direction, in said image data converting step, said image data is converted so as to shift a position of said nozzle combination along said first direction, and in said recording step, said image is recorded by using said recording head with said position of said nozzle combination shifted along said first direction on the basis of said converted image data after converting said image data in the image data converting step. - View Dependent Claims (13, 14)
