Patent ID: 8201915

Claim:
A discharge amount evaluation method of a liquid droplet discharging device that is performed to evaluate a discharge amount of a liquid discharged by the liquid droplet discharging device, the liquid including at least one of a solution prepared by dissolving a solute in a solvent and a dispersion prepared by dispersing a dispersoid in a dispersion medium, the method comprising: discharging the liquid by the liquid droplet discharging device on a receiving layer of a test piece, the test piece including the receiving layer that absorbs at least one of the solvent and the dispersion medium as components included in the liquid and a base layer that is abutted with the receiving layer and that does not absorb the at least one component absorbed by the receiving layer in the components included in the liquid; and evaluating the discharge amount of the liquid based on a result obtained by evaluating an area of an absorbing portion where the at least one absorbed component has spread in the receiving layer.
