  • Patent number: 11072187
    Abstract: An inkjet recording apparatus includes three or more recording heads. The recording heads contain different inks and eject the different inks sequentially on a recording medium. The different inks each contain a pigment and a polyhydric alcohol monobutyl ether. Of the different inks, an ink to be ejected first has the lowest pigment content ratio. Of the different inks, an ink to be ejected third and an ink to be subsequently ejected each have a pigment content ratio equal to or higher than that of a corresponding one of inks to be precedently ejected. Of the different inks, an ink to be ejected second and an ink to be subsequently ejected each have a polyhydric alcohol monobutyl ether content ratio higher than that of a corresponding one of inks to be precedently ejected.

  • Patent number: 11072721
    Abstract: An ink jet printing method includes printing an image on a printing medium including a transparent substrate and an ink-receiving layer on one side of the transparent substrate by applying a first ink and a second ink onto the surface of the ink-receiving layer of the printing medium in such a manner that the first ink and the second ink are at least partially superposed one on the other. The first ink is an aqueous ink containing silver particles, and the second ink is an aqueous ink containing a dye. The particle size at 50% in the cumulative volume distribution of the silver particles is larger than the average pore size of the ink-receiving layer.

  • Patent number: 11021627
    Abstract: Novel inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process, are disclosed. The novel ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent. The second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.

  • Patent number: 10974513
    Abstract: An example of an ink supply includes an ink chamber containing a liquid ink, a salt chamber containing a salt solution, a separator positioned between the liquid ink and the salt solution, and a release mechanism. The separator completely separates the liquid ink from the salt solution prior to the release mechanism being triggered. The release mechanism has a triggered position and a retracted position. The triggered position causes the separator to at least partially open, and enables the liquid ink and the salt solution to be combined to form a mixture.
