Print Control Device, Control Method of a Positioning Data, and Positioning System

A control method of a printing device that discharges a plurality of inks and records on a recording medium, the control method comprising:

• receiving input of a total correction ratio that uniformly corrects a discharge volume of each ink, and receiving input of a specific correction ratio that corrects the discharge volume of one specific ink in the group of plural inks;
• and
• correcting the discharge volume of the specific ink based on a value calculated from the total correction ratio and the specific correction ratio, and determining a corrected discharge volume for discharging the specific ink when printing.

A control method of a printing device that prints by discharging a plurality of inks onto a recording medium, the control method comprising:

• based on at least one of the specific correction ratio that reduces the discharge volume of one specific ink in the group of plural inks from the rated discharge volume of the specific ink, and the total correction ratio that reduces the discharge volume of each of the plural inks uniformly from the rated discharge volume of each ink, determining the actual discharge volume at which the specific ink is discharged when printing by reducing the rated discharge volume of the specific ink, and determining the actual discharge volumes at which each of the other inks are discharged when printing by increasing the rated discharge volume of each of the inks other than the specific ink in the group of plural inks.
