Printing Control Apparatus, A Printing System, and Printing Control Program

A printing system that includes a printing apparatus performing printing by depositing a plurality of color materials to a print medium and a printing control apparatus for designating a color material amount set that correspondes to amounts of the plurality of color materials, and controlling the printing based on the color material amount set, the printing system comprising:

• an index acquiring unit that acquires an index specifying a target;
• a confirmation patch printing unit that acquires the color material amount set corresponding to the acquired index with reference to a lookup table defining a correspondence relation between the index and the color material amount set, and designates the color material amount set to the printing apparatus to print a confirmation patch;
• a lookup table creating unit that creates the lookup table by estimating the color material amount set reproducing a target value, which is a status value representing a status of the target, on the print medium on the basis of a predetermined estimation model and defining a correspondence relation between the estimated color material amount set and the index specifying the target;
• and
• a revision unit that acquires a correction target value on the basis of a deviation between a measurement value obtained by measuring a status value representing a status of the confirmation patch and the target value, re-estimates the color material amount set reproducing the correction target value on the print medium by the printing apparatus on the basis of the estimation model, and revises the color material amount set defined in the lookup table by use of the re-estimated color material amount set.

A computer-readable printing control program causing a computer to execute a function of designating a color material amount set that corresponds to amounts of a plurality of color materials, to a printing apparatus and a function of performing printing based on the color material amount set, when controlling the printing apparatus to perform the printing by depositing the plural color materials to a print medium, the printing control program causing the computer to execute:

• an index acquiring function of acquiring an index specifying a target;
• and
• a confirmation patch printing function of acquiring the color material amount set corresponding to the acquired index with reference to a lookup table defining a correspondence relation between the index and the color material amount set, and designating the color material amount set to the printing apparatus to print a confirmation patch,
• wherein the lookup table is created by estimating the color material amount set reproducing a target value, which is a status value representing a status of the target, on the print medium on the basis of a predetermined estimation model and defining a correspondence relation between the estimated color material amount set and the index specifying the target, and
• wherein a correction target value is acquired on the basis of a deviation between a measurement value obtained by measuring a status value representing a status of the confirmation patch and the target value, the color material amount set reproducing the correction target value on the print medium by the printing apparatus is re-estimated on the basis of the estimation model, and the color material amount set defined in the lookup table is revised by use of the re-estimated color material amount set.
