An ink jet ink set includes a plurality of inks to be ejected by an ink jet method. The ink set includes a first ink containing metal particles, and a second ink containing a coloring agent selected from materials other than metal. The surface tension of the first ink is lower than that of the second ink.

A method for manufacturing a colored sheet for coloring an object by adhesion to the object includes, a coloring step of applying by spraying, a first coating fluid containing first microp articles for coloring to a thin film of a print receiver body which has a sheet-shaped support body and the thin film, the thin film being peelably held on the sheet-shaped support body to serve as a base material of an adhesive sheet which is to be adhered to the object, and a restricting step of applying by spraying, before the coloring step, a second coating fluid for restricting the first microparticles from penetrating the thin film to a location where the first coating fluid is to be applied.

In an example implementation, a method of printing with an emulsion, includes generating an emulsion of non-water based fluid and water based fluid on a printhead, and ejecting the emulsion through a printhead nozzle.

An aerosol jet printhead comprising an in-line static mixer can mix multiple aerosol streams for co-deposition from a single nozzle. A printhead was designed, fabricated, and tested, demonstrating in-plane functionally graded films. The inline mixing printhead can be used with a compact aerosol jet deposition system.

A production process comprises a formation process that includes: contacting a first liquid material and a second liquid material with each other at a contact point in a gas atmosphere, wherein at the contact point at least one of the first liquid material and the second liquid material is provided as a liquid jet propagating in a direction, to provide at the contact point a third jet of a coalesced third material propagating in a third direction. A production process device can perform the formation process.

A production process and a related device comprises a formation process comprising: contacting a first liquid material and a second liquid material with each other at a contact point in a gas atmosphere, wherein at the contact point at least one of the first liquid material and the second liquid material is provided as a liquid jet propagating in a direction, to provide at the contact point a third jet of a coalesced third material propagating in a third direction.

The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.

A fluid ejection device includes a fluid slot, three laterally adjacent fluid ejection chambers each having a drop ejecting element therein, a fluid circulation path communicated with each of the three laterally adjacent fluid ejection chambers, and a fluid circulating element within the fluid circulation path, with at least two laterally adjacent fluid ejection chambers of the three laterally adjacent fluid ejection chambers to substantially simultaneously eject drops of fluid therefrom such that the drops of fluid are to coalesce during flight.

An ink set includes an inkjet ink and a recording head filling liquid. The inkjet ink includes a pigment, a pigment coating resin, a first alkali metal ion, and water. The recording head filling liquid includes polyethylene glycol, a second alkali metal ion, a surfactant, and water. The polyethylene glycol has a mass average molecular weight of at least 180 and no greater than 800. A content ratio of the surfactant in the recording head filling liquid is greater than 0.00% by mass and no greater than 0.10% by mass. The first and second alkali metal ions each contain at least one of Li.sup.+, Na.sup.+, and K.sup.+.

A device for reproducing a color on demand. The device includes a body including a tip and a scanner. The body also includes a control unit, a plurality of ink reservoirs, an ink supply system, a mixing tank and a sensor. The control unit communicates with the scanner and ink supply system to reproduce a desired color that has been scanned.
