摘要： A liquid discharge apparatus includes: an ink composition containing 2-pyrrolidone and an alcohol having a main chain having 6 or less carbon atoms; a liquid discharge unit configured to discharge the ink composition from a nozzle formed in a nozzle surface; and a wiping unit configured to wipe the nozzle surface. The wiping unit includes a wiping member including protrusion-shape fibers. Each of the protrusion-shape fibers has a protruded portion in a cross-section orthogonal to a fiber axis thereof. The protruded portion is continuous in a direction along the fiber axis.

摘要： An inkjet printing device includes an ink container accommodating a clear ink containing a resin and an organic solvent, a discharging head including a nozzle plate, the discharging head being configured to discharge the clear ink onto a substrate to form a printing layer on the substrate, and a heating device configured to heat the substrate, wherein the heating device heats the substrate satisfying the following relationship:
Tmatte (degrees C.)>Tgloss (degrees C.), where Tmatte represents a temperature of the substrate in a first printing region when the clear ink is attached to the substrate in a first printing mode and Tgloss represents a temperature of the substrate in a second printing region when the clear ink is attached to the substrate in a second printing mode, wherein the receding contact angle of the clear ink against the nozzle plate is 35 degrees or greater.
