Liquid discharge control apparatus, liquid discharge control method, and liquid discharge control program

A liquid discharge control method that allows a printing apparatus including a printing head linearly driven in a direction across a printing medium to perform printing whose execution number of scan operations by the printing head is changed in accordance with a printed region, the liquid discharge control method comprising:

• printing a plurality of color patches targeting predetermined pre-color conversion data and based on a plurality of mutually different color conversion tables that bring about mutually different color conversion results by performing the printing whose execution number of the scan operations is changed, the plurality of color patches forming a plurality of groups each including a pair of two color patches;
• acquiring a selection result of a selection of one or more color patches from among the plurality of color patches;
• selecting, when printing whose execution number of the scan operations corresponds to each of the selected one or more color patches is performed, a color conversion table included in the plurality of mutually different color conversion tables and having been used in the selection of the each of the one or more color patches, and performing a color conversion using the selected color conversion table;
• and
• printing one of the two color patches forming the pair using a color conversion table constituting the plurality of mutually different color conversion tables and being common to the plurality of groups, and printing another one of the two color patches forming the pair using a color conversion table constituting the plurality of mutually different color conversion tables and being different for each of the plurality of groups.

A non-transitory computer readable medium storing a liquid discharge control program that allows a printing apparatus including a printing head linearly driven in a direction across a printing medium to perform printing whose execution number of scan operations by the printing head is changed in accordance with a printed region, the liquid discharge control program being configured to allow a computer to execute processing comprising:

• a process of printing a plurality of color patches targeting predetermined pre-color conversion data and based on a plurality of mutually different color conversion tables that bring about mutually different color conversion results by performing the printing whose execution number of the scan operations is changed, the plurality of color patches forming a plurality of groups each including a pair of two color patches;
• a process of acquiring a selection result of a selection of one or more color patches from among the plurality of color patches;
• a process of selecting, when printing whose execution number of the scan operations corresponds to each of the selected one or more color patches is performed, a color conversion table included in the plurality of mutually different color conversion tables and having been used in the selection of the each of the one or more color patches, and of performing a color conversion using the selected color conversion table;
• and
• a process of printing one of the two color patches forming the pair using a color conversion table constituting the plurality of mutually different color conversion tables and being common to the plurality of groups, and of printing another one of the two color patches forming the pair using a color conversion table constituting the plurality of mutually different color conversion tables and being different for each of the plurality of groups.
