6. The print control method according to claim 5, wherein 1/n of a width of the head in a sub-scanning direction is equal to or greater than a pitch between adjacent orifices of the head.
7. The print control method according to claim 1 or 2, characterized by further comprising:
acquiring an error compensation calibration printing file and the original width and the original height of an image corresponding to the error compensation calibration printing file;
printing an image according to the error compensation calibration print file;
measuring an actual printing width and an actual printing height of the image;
respectively calculating an error coefficient of the printing width and an error coefficient of the printing height according to the original width, the original height, the actual printing width and the actual printing height;
and correcting the width and the height of the subsequent file to be printed according to the error coefficient of the printing width and the error coefficient of the printing height.
8. A print control apparatus, characterized in that the apparatus comprises:
the printing covering times acquiring module is used for acquiring the printing covering times in the unit area, wherein the printing covering times are n, and n is a natural number;
the first control module is used for controlling the spray head to continuously scan for n times along the main scanning direction, and in the continuous scanning process of the n times, the spray head and the printing stock do not move or move for a distance which is less than the distance between two adjacent spray holes on the spray head in a sub-scanning direction which is orthogonal to the main scanning direction;
and the second control module is used for controlling the spray head and the printing stock to relatively move along the sub-scanning direction before the n times of continuous scanning or after the n times of continuous scanning and then printing.
9. A printer, comprising:
a spray head;
print control means for controlling the head to perform ink jet printing, the print control means being the print control means according to claim 8.
10. A computer-readable storage medium having computer program instructions stored thereon, which when executed by a processor implement the method of any one of claims 1-7.
