Print control apparatus, print control method, and print control program

摘要

A print control apparatus is configured to control a print head adapted to discharge ink droplets of a plurality of sizes to execute printing. The print control apparatus includes a print control unit configured to acquire a gradation value of an ink color based on image data and to determine whether or not to discharge an ink droplet of one of the plurality of sizes based on the gradation value. The print control unit is configured to determine that the ink droplet to be discharged is the ink droplet of a first size or smaller when the gradation value belongs to a maximum value-side partial range including a maximum value, and to determine that the ink droplet to be discharged is only the ink droplet of the first size when the gradation value belongs to a range towards a minimum value-side than the partial range.

1. A print control apparatus configured to control a print head adapted to discharge ink droplets of a plurality of sizes to execute printing, the print control apparatus comprising:
a print control unit configured to acquire a gradation value of an ink color based on image data, to determine whether or not to discharge an ink droplet of one of the plurality of sizes based on the gradation value, and to control discharging of the ink droplets by the print head in accordance with determination, the print control unit being configured to determine that the ink droplet to be discharged by the print head is the ink droplet of a first size and the ink droplet of a size smaller than the first size when the gradation value belongs to a maximum value-side partial range including a maximum value, and to determine that the ink droplet to be discharged by the print head is only the ink droplet of the first size when the gradation value belongs to a range towards a minimum value-side than the partial range, the print control unit being further configured to execute at least:
a first discharge mode, for determining that the ink droplet to be discharged by the print head is the ink droplet of the first size or the ink droplet of the size smaller than the first size when the gradation value belongs to the partial range, and determining that the ink droplet to be discharged by the print head is only the ink droplet of the first size when the gradation value belongs to the range towards the minimum value-side than the partial range; anda second discharge mode, for determining that the ink droplet to be discharged by the print head is the ink droplet of the size smaller than the first size when the gradation value belongs to a second partial range further towards the minimum value-side including a minimum value, the first discharge mode being executed in a case of using a first recording medium resistant to ink droplet bleeding, and the second discharge mode being executed in a case of using the second recording medium, wherein the first recording medium and the second recording medium differ in how readily an ink droplet that has struck bleeds.
