3. The on-foil object color adjustment device of claim 1 , wherein

the foil area is divided into a plurality of foil division areas, and

the ratio includes a ratio of a size of a non-bonded area in each of the foil division areas to a size of the foil division area; and

the hardware processor recognizes the printable recording medium as a wasted recording medium when the ratio of the size of the non-bonded area in the foil division area to the size of the foil division area is greater than or equal to a predetermined value in a predetermined number of foil division areas.

4. The on-foil object color adjustment device of claim 1 , wherein

the hardware processor:

judges whether a normal object to be printed around the foil area exists;

calculates a second influence degree indicating an influence of the non-bonded area and the normal object on the color of the on-foil object when the hardware judges that the normal object to be printed around the foil area exists; and

adjusts color data of the normal object to be printed around the foil area based on the calculated second influence degree, wherein

the calculated second influence degree is based on the ratio of the size of the non-bonded area in the foil area to the size of the foil area, the color of the non-bonded area in the foil area, the color of the foil used in the foil area, the color data of the on-foil object to be printed in the foil area after the foil-bonding and the normal object to be printed around the foil area.

5. The on-foil object color adjustment device of claim 4 , wherein the hardware processor adjusts the color data of the on-foil object based on the calculated second influence degree.

6. An on-foil object color adjustment device, comprising:

a data receiver that obtains non-bonded area data including a ratio of a size of a non-bonded area within a foil area to a size of the foil area, wherein

the non-bonded area is an area where a foil is not bonded in the foil area after foil-bonding is carried out for a printable recording medium, and

the foil area is an area where a foil-bonding object is printed on the printable recording medium by using a foil-bonding toner and in which the foil-bonding is carried out after the foil-bonding object is printed; and

a hardware processor that:

calculates, based on the obtained ratio, a color of the non-bonded area, a color of the foil, and color data of an on-foil object, a first influence degree indicating an influence of the non-bonded area on a color of the on-foil object to be printed in the foil area after the foil-bonding; and

adjusts the color data of the on-foil object based on the calculated first influence degree.

7. The on-foil object color adjustment device of claim 6 , wherein

a plurality of foil areas exists in the printable recording medium, and

the ratio includes a ratio of a size of a non-bonded area in each of the foil areas to the size of the foil area; and

the hardware processor:

calculates, for each of the foil areas, the first influence degree based on the ratio of the size of the non-bonded area in each foil area to the size of the foil area, the color of the non-bonded area in each foil area, the color of the foil used in each foil area, and the color data of the on-foil object to be printed in each foil area after the foil-bonding; and

adjusts the color data of the on-foil object to be printed in each foil area based on the calculated first influence degree for each foil area.

8. The on-foil object color adjustment device of claim 6 , wherein

the foil area is divided into a plurality of foil division areas, and

the ratio includes a ratio of a size of a non-bonded area in each of the foil division areas to a size of the foil division area; and

the hardware processor recognizes the printable recording medium as a wasted recording medium when the ratio of the size of the non-bonded area in the foil division area to the size of the foil division area is greater than or equal to a predetermined value in a predetermined number of foil division areas.

9. The on-foil object color adjustment device of claim 6 , wherein

the hardware processor:

judges whether a normal object to be printed around the foil area exists;

calculates a second influence degree indicating an influence of the non-bonded area and the normal object on the color of the on-foil object when the hardware judges that the normal object to be printed around the foil area exists; and

adjusts color data of the normal object to be printed around the foil area based on the calculated second influence degree, wherein

the calculated second influence degree is based on the ratio of the size of the non-bonded area in the foil area to the size of the foil area, the color of the non-bonded area in the foil area, the color of the foil used in the foil area, the color data of the on-foil object to be printed in the foil area after the foil-bonding and the normal object to be printed around the foil area.
