摘要:
An ink jet method includes feeding an ultraviolet curing type ink jet composition from a composition storing body which stores an ultraviolet curing type ink jet composition, which contains a polymerizable compound and a hindered amine compound as a polymerization inhibitor, with a storing volume of the composition of 2 L or more to an ink jet head through a channel, deaerating the ultraviolet curing type ink jet composition in the channel, and discharging the ultraviolet curing type ink jet composition from the ink jet head, in which an amount of a dissolved gas of the ultraviolet curing type ink jet composition after the deaeration is 30 ppm or less and an amount of a dissolved gas of the ultraviolet curing type ink jet composition stored in the composition storing body is 10 ppm or more.

A recording method includes first coating a treatment liquid A to a recording medium, a second coating a treatment liquid B to the recording medium after the first coating, and a discharging an ink composition including a coloring material to the recording medium by discharging from a nozzle after the second coating, and the treatment liquid A adjusts wettability of the treatment liquid B to the recording medium and includes at least any one of a resin and inorganic oxide fine particles, and the treatment liquid B thickens or insolubilizes the ink composition and includes at least any one of a polyvalent metal salt, an organic acid, and an organic acid salt.
摘要:
A cleaning method of an ink supply path in a recording apparatus where ink is supplied from an ink cartridge, includes a first cleaning step of cleaning by supplying to the ink supply path a gas-liquid mixture of a cleaning liquid A provided with an ink cleaning action and gas, and a second cleaning step of cleaning by supplying to the ink supply path a cleaning liquid B provided with an air bubble suppressing action after the first cleaning step.
摘要:
An aqueous ink jet ink composition contains a water-insoluble colorant, a lignosulfonate salt, and at least one element A selected from the group consisting of Ca, Mg, Mn, Fe, Al, and Si, and a total content of the element A is 5 to 120 mass ppm.
摘要:
An aqueous ink jet ink composition includes a natural-derived carbide, a dispersant, and a water-soluble organic solvent, the carbide is a carbide obtained by performing a complex separation treatment and an acid dissolution treatment on an untreated carbide, the complex separation treatment is a treatment to remove a complex obtained by mixing the untreated carbide and a chelating agent, and the acid dissolution treatment is a treatment to remove a water-soluble salt obtained by mixing the untreated carbide and an acid.
摘要:
An ink set includes a reaction liquid containing coagulant; a first ink containing a color material; and a second ink containing a color material. The ink set is used for recording on a non-absorptive recording medium or a low-absorptive recording medium and for imparting the reaction liquid, the first ink, and the second ink to the recording medium in a superimposed manner in this order.
摘要:
An aqueous ink jet ink composition contains a color material, water, a polyhydric alcohol having a standard boiling point of 270.0° C. or more, and 1-(2-hydroxyethyl)-2-pyrrolidone. The mass ratio of the content of the polyhydric alcohol to that of 1-(2-hydroxyethyl)-2-pyrrolidone is 3.1 or more and 7.0 or less.
