Test method
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.
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 of the ink-receiving layer;
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 a contrast between a contour of a first portion of the test medium, that has absorbed the ink and swelled in the thickness direction, and a second portion of the test medium, that has absorbed the ink less than the first portion, the second portion being adjacent to the first portion.
2. 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.
3. 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.
4. 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.
5. The test method according to claim 1 , wherein the observing the test medium includes detecting stain of mist generated by ejecting the droplets.
6. 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.
7. The test method according to claim 1 , wherein the ink-receiving layer is made of a material containing a coloring agent.
8. The test method according to claim 1 , wherein the ink-receiving layer contains polyvinyl butyral.
9. 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.
10. The test method according to claim 1 , wherein the ink-receiving layer is made of a material containing an anionic acrylic silicone.
11. The test method according to claim 1 , wherein the ink-receiving layer has a thickness in the range of 10 to 500 μm.
12. 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.
13. The test method according to claim 1 , wherein the ink contains an organic solvent having a boiling point of 100° C. or more.
14. The test method according to claim 1 , wherein the ink contains an aprotic aromatic compound as a liquid component.
15. The test method according to claim 1 , wherein the ink does not contain a coloring agent.
