The condition (a) is that a surface tension of an aqueous solution at a concentration of 10 percent by mass is 42 to 56 mN/m, the condition (b) is that a standard boiling point is 150° C. to 300° C., and the condition (c) is that a solubility in water at 20° C. is 1 percent by mass or less.

A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

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.

Ink compositions and methods of use for reliably printing on alkaline and readily oxidizing surfaces comprise one or more water-soluble polymeric dyes, one or more solvents for adjusting viscosity, surface tension, and/or heat tolerance, and water, the dyes being “loaded” in the ink sufficiently to meet the relevant color and optical density requirements for the ink while such ink composition still also meets the duty cycle requirements of the application.

A process for preparing a printed rigid plastic substrate is described, the process comprising: providing a rigid plastic substrate comprising a primer on a surface of the rigid plastic substrate, the primer comprising a primer resin; printing a liquid electrophotographic ink composition comprising a thermoplastic resin onto the primer on the surface of the rigid plastic substrate; depositing a cross-linking composition comprising a cross-linker onto the printed electrophotographic ink composition disposed on the primer; and laminating the rigid plastic substrate with a flexible film such that the ink composition and the cross-linker are disposed between the rigid substrate and the flexible film and wherein the lamination of the rigid substrate with the flexible film causes cross-linking of the thermoplastic resin of the ink composition and of the primer resin.

Eco-friendly signs such as wood and other natural material signs, and methods of making eco-friendly signs, including selecting a substrate as a base material having a first planar surface and an opposing second planar surface, cutting the substrate to a sign dimension, treating the first planar surface to form a smooth print surface, applying a base layer such as a layer of clear ink to the print surface, and applying a signage layer onto the base layer. The eco-friendly sign may be an ADA compliant sign in which the signage layer is a raised of ink produced using a 3-dimensional printer.

Provided are an ink set including a colored ink containing a colored pigment which is at least one of a chromatic pigment or a black pigment, a pigment dispersant, and water, and a white ink containing a white pigment, a pigment dispersant, and water, in which the pigment dispersants respectively contained in the colored ink and the white ink contain a polymer having a crosslinked structure or a block polymer, and an image recording method.

A recording apparatus that causes less degradation of image quality due to blurring caused by dot misalignment between an ink containing a coloring material and a reaction liquid includes a recording unit configured to record an image on a recording medium by applying an ink containing a coloring material and a reaction liquid containing a component that aggregates the coloring material, an acquisition unit configured to acquire multi-valued ink data to apply the ink, and a generating unit configured to generate first multi-valued reaction liquid data based on the multi-valued ink data and, when a tone value of a pixel of interest in the first multi-valued reaction liquid data is lower than a tone value of any one of a plurality of surrounding pixels around the pixel of interest, generate second multi-valued reaction liquid data by increasing the tone value of the pixel of interest.
