Document Type and Number:
Japanese Patent JP7468134
Kind Code:
B2
Abstract:
The present invention provides a means for suppressing drying and solidification of an ink on the nozzle surface of a head. This cleaning liquid is used for the purpose of cleaning a nozzle surface 33A of a printing head 34 that discharges an aqueous ink from a nozzle 33. This cleaning liquid contains a water-soluble organic solvent and a surfactant. The waler-soluble organic solvent contains a solvent A which has a saturated vapor pressure of 1.0 Pa or less at 20°C, in an amount of 60% by mass or more relative to the total mass of the waler-soluble organic solvent. The ratio of the mass equal to 1,000 times the total mass of the surfactant to the mass of the solvent A is greater than 0.5. The velocity at which a droplet of the cleaning liquid slides down on the nozzle surface 33A is 3.0 mm/second or less.
