## Abstract

A test method includes preparing a test medium including a base and an ink-receiving layer that absorbs ink to swell in the thickness direction thereof, applying an ink onto the ink-receiving layer by ejecting droplets of the ink from a liquid ejecting apparatus, and observing the test medium.

## Claims

### Claim 1

A test method comprising:
preparing a test medium including a base and an ink-receiving layer that absorbs ink to swell in the thickness direction thereof;
applying an ink onto the ink-receiving layer by ejecting droplets of the ink from a liquid ejecting apparatus by an ink jet method; and
observing the test medium.

### Claim 2 (depends on 1)

The test method according to claim 1, wherein the observing of the test medium is performed through a microscope including an epi-illumination lighting device.

### Claim 3 (depends on 1)

The test method according to claim 1, wherein the observing of the test medium includes measuring the volume of the droplets ejected from the liquid ejecting apparatus.

### Claim 4 (depends on 1)

The test method according to claim 1, wherein the observing of the test medium including detecting positional information of the droplets ejected from the liquid ejecting apparatus.

### Claim 5 (depends on 1)

The test method according to claim 1, wherein the observing the test medium includes detecting stain of mist generated by ejecting the droplets.

### Claim 6 (depends on 1)

The test method according to claim 1, wherein the ink-receiving layer absorbs 0.2 g or more of the ink per gram thereof, and the base absorbs 0.1 g or less of the ink per gram thereof.

### Claim 7 (depends on 1)

The test method according to claim 1, wherein the ink-receiving layer is made of a material containing a coloring agent.

### Claim 8 (depends on 1)

The test method according to claim 1, wherein the ink-receiving layer contains polyvinyl butyral.

### Claim 9 (depends on 8)

The test method according to claim 8, wherein the polyvinyl butyral contains 10% to 40% by mass of vinyl alcohol having a hydroxy group that is not acetalized or etherified, or esterified.

### Claim 10 (depends on 1)

The test method according to claim 1, wherein the ink-receiving layer is made of a material containing an anionic acrylic silicone.

### Claim 11 (depends on 1)

The test method according to claim 1, wherein the ink-receiving layer has a thickness in the range of 10 to 500 μm.

### Claim 12 (depends on 1)

The test method according to claim 1, wherein the base contains a compound selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyimide, polyacrylate, polyacetal, polyvinylidene chloride, and polyphenylene sulfide.

### Claim 13 (depends on 1)

The test method according to claim 1, wherein the ink contains an organic solvent having a boiling point of 100° C. or more.

### Claim 14 (depends on 1)

The test method according to claim 1, wherein the ink contains an aprotic aromatic compound as a liquid component.

### Claim 15 (depends on 1)

The test method according to claim 1, wherein the ink does not contain a coloring agent.
