## Abstract

A printing method comprises supplying a flocculant for promoting aggregation reaction of aggregative material that gels by aggregation to at least a region of a printing medium having a small capillary force, shooting droplets of ink containing the aggregative material by an ink jet method to at least the region of the printing medium having a small capillary force, and fixing the ink that has gelled by the aggregation reaction between the aggregative material and the flocculant onto the printing medium.

## Claims

### Claim 1

A printing method of printing by an ink jet method on a printing medium containing a region where ink is not easily retained due to a small capillary force, the printing method comprising:
supplying a flocculant for promoting aggregation reaction of aggregative material that gels by aggregation to at least a region of a printing medium having a small capillary force,
shooting droplets of ink containing the aggregative material by an ink jet method to at least the region of the printing medium having a small capillary force, and
fixing the ink that has gelled by the aggregation reaction between the aggregative material and the flocculant onto the printing medium.

### Claim 2 (depends on 1)

The printing method according to claim 1,
wherein the flocculant is supplied with its size and amount adjusted so that liquid droplets supplied to the region of the printing medium having a small capillary force do not move from the region of the printing medium having a small capillary force.

### Claim 3 (depends on 2)

The printing method according to claim 2,
wherein the flocculant is supplied with its size and amount adjusted by atomization.

### Claim 4 (depends on 1)

The printing method according to claim 1,
wherein the ink containing the aggregative material is supplied so as to gel before the flocculant supplied to the region of the printing medium having a small capillary force moves from the region of the printing medium having a small capillary force.

### Claim 5 (depends on 1)

The printing method according to claim 1,
wherein a deactivator adapted to deactivate the aggregation reaction between the flocculant and the aggregative material is supplied to a region of the printing medium having a great capillary force before the flocculant is supplied.

### Claim 6 (depends on 1)

The printing method according to claim 1,
wherein the flocculant is supplied only to the region of the printing medium having a small capillary force.

### Claim 7 (depends on 1)

The printing method according to claim 1,
wherein the aggregative material contains an aqueous polymer dispersed in an aggregative material dispersion liquid and is aggregated by the flocculant to increase in viscosity.

### Claim 8 (depends on 1)

The printing method according to claim 1,
wherein the aggregation reaction is caused using the aggregative material containing an anionic surfactant dispersed in an aggregative material dispersion liquid and using an acid as the flocculant.

### Claim 9 (depends on 1)

The printing method according to claim 1,
wherein the aggregation reaction is caused using the aggregative material containing an organic cationic polymer dispersed in an aggregative material dispersion liquid and using an anionic surfactant as the flocculant, or
the aggregation reaction is caused using the aggregative material containing an organic anionic polymer dispersed in an aggregative material dispersion liquid and using cationic surfactant as the flocculant.

### Claim 10 (depends on 1)

The printing method according to claim 1,
wherein the region of the printing medium having a small capillary force comprises a raised texture.

### Claim 11 (depends on 1)

The printing method according to claim 1,
wherein the region of the printing medium having a small capillary force comprises a polyester-made structure.

### Claim 12 (depends on 1)

The printing method according to claim 1,
wherein the printing medium is a nonwoven fabric, where the region having a great capillary force includes a region having a high fiber density.

### Claim 13

A printing device for printing by an ink jet method on a printing medium containing a region where ink is not easily retained due to a small capillary force, the device comprising:
a flocculant supplier adapted to supply a flocculant for promoting aggregation reaction of an aggregative material that gels by aggregation to at least a region of the printing medium having a small capillary force,
an ink supplier adapted to shoot droplets of ink containing the aggregative material by an ink jet method to at least the region of the printing medium having a small capillary force, and
a fixing device adapted to fix the ink that has gelled by the aggregation reaction between the aggregative material and the flocculant onto the printing medium.

### Claim 14

A printing method of printing by an ink jet method on a printing medium having a region that extends from a front surface through to a reverse surface and permits easy penetration of ink by virtue of a great capillary force, the printing method comprising:
supplying a flocculant for promoting aggregation reaction of an aggregative material that gels by aggregation to a given region in at least one of a front surface region and a reverse surface region of the printing medium,
shooting droplets of ink containing the aggregative material by an ink jet method to the given region, and
fixing the ink that has gelled by the aggregation reaction between the aggregative material and the flocculant onto the given region of the printing medium.

### Claim 15 (depends on 14)

The printing method according to claim 14,
wherein, after the flocculant is supplied to the front surface region and the reverse surface region of the printing medium, the droplets of the ink containing the aggregative material are shot at the front surface region and the reverse surface region of the printing medium.
