Abstract: The ink discharge unit includes a biasing member. The biasing member is fixed to a fixing member immovably fitted to a carriage body that moves relative to a recording medium. The biasing member, while being thus fixed, biases an inkjet head in a direction illustrated with an arrow and in a direction illustrated with another arrow for position alignment of the inkjet head relative to the fixing member. The inkjet head, while being biased by the biasing member, is fixed to the fixing member. The fixing member has curved portions that regulate movements of the inkjet head in the directions illustrated with the arrows by way of contacts with the inkjet head.

Abstract: Ultraviolet curable ink contained in an ink pack is prevented from curing during storage. The second resin layer, the metal layer, and the protective layer in the upper film of the surface portion of the ink pack extend from the base layer (extended portion). The metal layer has a light-shielding property, and the extended portion is folded back and attached to the surface of the lower film of the side-surface portion. The metal layer having a light-shielding property thus covers the base layers exposed at the end surface of the joint portion, and can prevent external ultraviolet rays from reaching the ink through the base layers.

Abstract: The present invention provides an inkjet printing apparatus in which aggregate or the like clogged in a nozzle is sucked to recover the clogged nozzle and provides a clogged nozzle recovering method. The inkjet printing apparatus in accordance with the present invention includes a cap which is structured to cover some of plural nozzles formed in a nozzle face of a head of an inkjet printer, a pressure sensor which acquires a pressure in an inside of the cap in a state that the some of the plural nozzles are covered by the cap, a suction means which sucks the inside of the cap with a pressure lower than a negative pressure at which a meniscus of a nozzle that is not covered with the cap is broken, and a nozzle recovery judgment means which judges recovery of a nozzle by comparing a reference pressure value, which is obtained when nozzles without being clogged are covered by the cap and sucked and is stored beforehand, with a pressure value which is outputted from the pressure sensor.

Abstract: In a method for printing a metal-tone printed matter, a metallic ink which includes metal particles dispersed in a solvent is applied onto a smooth printing surface of a printing medium to provide a metallic ink layer containing a metal layer having the metal particles accumulated on a printing surface side closer to the smooth printing surface in the metallic ink layer. The printing medium is reversed to transfer the metallic ink layer onto a material to be transferred while making a smooth surface of the metal layer as a display surface.

Abstract: A sub tank configured to supply ink supplied from a main tank to a print head while suppressing a pressure fluctuation is formed with an ink storage chamber in which the ink is stored, and includes a filter configured to allow passage of the ink while suppressing passage of the fine particles when the fine particles of the ink are precipitated, an ink introducing portion configured to introduce the ink supplied from the outside into the ink storage chamber, and an ink discharging portion configured to discharge the ink in the ink storage chamber to the outside. The filter divides the ink storage chamber into an introducing-side storage chamber communicating with the ink introducing portion, and a discharging-side storage chamber communicating with the ink discharging portion, and the discharging-side storage chamber is arranged on an upper side of the introducing-side storage chamber in the perpendicular direction.
