Production of color space conversion profile based on correspondence of grid points and ink amounts

A device for producing a profile specifying the correspondence relationship of values in different color spaces, comprising:

• a first correspondence relationship acquisition unit for acquiring a first correspondence relationship constituted by a plurality of correspondence relationships of ink amounts and color values;
• a grid point acquisition unit for setting a plurality of grid points for which a relative positional relationship in a predetermined color space is defined;
• a second correspondence relationship acquisition unit for acquiring a second correspondence relationship constituted by a plurality of correspondence relationships of the grid points and color values;
• a third correspondence relationship acquisition unit for acquiring a third correspondence relationship constituted by a plurality of correspondence relationships of the grid points and ink amounts based on the first correspondence relationship and the second correspondence relationship;
• and
• a profile production unit for producing a profile specifying the third correspondence relationship.

A computer readable product storing a program for producing a profile specifying the correspondence relationship of values in different color spaces, this program causing a computer to execute:

• a first correspondence relationship acquisition program code for acquiring a first correspondence relationship constituted by a plurality of correspondence relationships of ink amounts and color values;
• a grid point acquisition program code for setting a plurality of grid points for which a relative positional relationship in a predetermined color space is defined;
• a second correspondence relationship acquisition program code for acquiring a second correspondence relationship constituted by a plurality of correspondence relationships of the grid points and color values;
• a third correspondence relationship acquisition program code for acquiring a third correspondence relationship constituted by a plurality of correspondence relationships of the grid points and ink amounts based on the first correspondence relationship and the second correspondence relationship;
• and
• a profile production program code for producing a profile specifying the third correspondence relationship.
