Wherein the painting information generating unit comprises:
Wherein when the ink ejection amount to be ejected to each of the points is calculated separately according to the position of the ink nozzle, Is determined to be within a predetermined basic printing distance, and if it is determined that the distance from the ink nozzle to a specific point is within the basic printing distance, the amount of ink to be jetted to the specific point is calculated as a predetermined basic value And calculating an injection amount of the ink to be injected at the specific point according to a first calculation expression if it is determined that the distance from the ink nozzle to a specific point exceeds the basic printing distance,
The first calculation formula is:
If the predetermined basic value is q, the predetermined basic printing distance is d, the distance from the ink nozzle to a specific point is D, and the injection amount of ink to be jetted to the specific point is Q,

Wherein the printing system is a color printing system. 11. The method of claim 10,
Wherein the painting information generating unit comprises:
Information about the injection amount of the ink to be injected for each of the points is visualized so that a distribution image is generated,
In the distribution image,
Wherein the visualized value is visualized so that the brightness value decreases in proportion to the amount of ink to be jetted per unit area at each point. Causing the shape information obtaining unit to obtain shape information on the object;
The subject is fixed by the subject fixing unit;
Causing the distance information obtaining unit to separately obtain distance information from the ink nozzles to a plurality of points located on the surface of the subject when the shape information is obtained;
A step of separately calculating an injection amount of ink to be sprayed to each point based on the shape information and the distance information by a painting information generating unit;
Causing the painting information generating unit to map the information on the amount of ink to be sprayed to each of the individually calculated points and the distance information to generate painting information; And
At least one of the subject fixing unit and the ink jetting unit is transferred such that at least one of the subject fixing unit and the ink jetting unit is transported and the ink jetting unit ejects ink toward the subject, / RTI &gt;
