Abstract

A treatment-liquid application device includes a treatment liquid applicator to apply a treatment liquid to an application target object to which a black liquid and a color liquid other than the black liquid are applied. The treatment liquid applicator applies a greater amount of the treatment liquid per unit area to at least a region to which the color liquid is applied than a region to which the black liquid is applied.

First claim

The invention claimed is:

1. A treatment-liquid application device comprising a treatment liquid applicator to apply a treatment liquid to an application target object to which a black liquid and a color liquid other than the black liquid are applied,
wherein the treatment liquid applicator applies a greater amount of the treatment liquid per unit area to at least a region to which the color liquid is applied than a region to which the black liquid is applied.

2. The treatment-liquid application device according to claim 1 ,
wherein the treatment liquid is a treatment liquid to increase conductivity.

3. The treatment-liquid application device according to claim 1 ,
wherein the treatment liquid is a treatment liquid to increase dielectric constant.

4. The treatment-liquid application device according to claim 1 ,
wherein the treatment liquid applicator does not apply the treatment liquid to the region to which the black liquid is applied.

5. The treatment-liquid application device according to claim 1 ,
wherein the treatment liquid comprises propylene glycol or glycerin.

6. A drying device comprising:
the treatment-liquid application device according to claim 1 ; and
a heating device to heat the application target object.

7. The drying device according to claim 6 ,
wherein the heating device is a dielectric heating device.

8. A liquid discharge apparatus comprising:
the drying device according to claim 6 ; and
a liquid discharger to apply the black liquid and the color liquid to the application target object.

9. A liquid discharge apparatus comprising:
the treatment-liquid application device according to claim 1 ; and
a liquid discharger to apply the black liquid and the color liquid to the application target object.

10. The liquid discharge apparatus according to claim 9 ,
wherein the treatment-liquid application device is disposed on an upstream side of the liquid discharger in a movement direction of the application target object.

11. The liquid discharge apparatus according to claim 9 ,
wherein the treatment-liquid application device is disposed on a downstream side of the liquid discharger in a movement direction of the application target object.

12. The liquid discharge apparatus according to claim 9 ,
wherein the liquid comprises propylene glycol or glycerin.

13. The treatment-liquid application device according to claim 1 ,
wherein a drying efficiency of the treatment liquid is higher than a drying efficiency of the color liquid.

14. A treatment-liquid application device comprising:
a treatment liquid applicator to apply a treatment liquid to an application target object to which a first liquid and a second liquid are applied, the first liquid including carbon black, the second liquid including no carbon black or a smaller amount of carbon black than the first liquid, wherein the treatment liquid applicator applies a greater amount of the treatment liquid per unit area to at least a region to which the second liquid is applied than a region to which the first liquid is applied.
