A decorative paper layer may include a base paper layer, an inkjet receiver coating and a pattern formed thereon by digitally applying inks from a set of a plurality of differently colored inks. At least one of the inks may include color pigments having an average particle diameter larger than 150. The inkjet receiver coating may include silica pigments, in which the silica particles are particles of precipitated silica and/or silica gel and/or have an average particle size which is at least 4 times larger than the average particle diameter of the color pigments and/or have an average particle size of 1 to 40 micrometer.

A method and apparatus for forming an optical device are described. The optical device is formed by depositing a plurality of ink drops on a surface of a substrate. The plurality of ink drops are contained within a chemical stopper, such that the chemical stopper surrounds each individual ink drop. The chemical stopper is configured to reduce reflow of the ink drops and is a fraction of the height of each of the ink drops. The ink drops are baked after being deposited within the chemical stoppers as liquid ink drops.

A method for manufacturing printed products contains the steps of applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process. An essentially colorless and water-containing liquid is applied a) to non-image regions and/or b) to image regions that have only little ink in the drop-on-demand process. The printing material is dried. The printing material has a coating that contains at least one acid. After the application of ink and the application of a liquid, a water-containing further liquid, for instance a varnish, is applied both to image regions and to non-image regions of the printing material, and that the liquid and/or the further liquid contains at least one substance that at least partly neutralizes the acid. The undesired formation of waves and glossiness fluctuations between varnished image regions and varnished non-image regions may thus advantageously be avoided.

Printable substrates that provide a glossy printable surface with solvent resistance are provided. The printable substrate may include a base sheet having a first surface and a second surface, and a printable coating on the first surface. The printable coating includes a film-forming binder mixture, a crosslinking agent, a partially hydrolyzed polyvinyl alcohol, a first plurality of first silicon dioxide microparticles, a second plurality of second silicon dioxide microparticles, and a cationic dye fixative. The printable substrate may have a gloss level of about 50 to about 60 based on measurement of a gloss meter set with an angle of measurement of 75 degree on the external surface of the printable coating.

A method is provided for printing onto a décor paper and/or foil that may be suitable for being used in decorative panels. The method may involve providing a printable substrate. A pattern may be printed on the printable substrate by ejecting droplets of ink by means of at least one inkjet printing head that may include one or more nozzles. After a first predetermined time period, the printing operation may be interrupted for a second predetermined time period and/or a controlling frequency of the printhead may be changed for a second predetermined time period.

The present disclosure is drawn to a coated print medium, a method of preparing a print medium, and a printing system. The coated print medium can comprise a substrate and a coating applied to the substrate. The coating can comprise, by solids or dry weight, 5 wt % to 30 wt % of a polymeric binder, 20 wt % to 50 wt % of a cationic latex, 5 wt % to 15 wt % of a multivalent cationic salt, and 1 wt % to 20 wt % of a sulfonic acid- or sulfonate-containing stilbene optical brightener.

This invention relates to a conductive thermal image receiver element that has an aqueous coatable dye-receiving layer. The dye-receiving layer comprises a conductive polymeric material, a dispersant, one or more surfactants, one or more antifoamers, a water-dispersible release agent, a crosslinking agent, and a polymer binder matrix consisting essentially of a water-dispersible polyester and a water-dispersible acrylic polymer. This invention also relates to a method for making this thermal image receiver element as well as method for using it to provide a dye image by thermal transfer from a donor element.

The present invention relates to a decorative material having excellent printability, and the decorative material according to the present invention has an ink-receiving layer having a radially fine sloping structure having a dendritic shape, whereby the absorbing and/or fixing property, i.e., printability, of the ink printed on the ink-receiving layer is improved, and clarity is excellent, so that aesthetic effects are excellent. In addition, since the ink-receiving layer is manufactured through UV curing, it can be directly coated on a substrate layer, and can include various kinds of substrate layers; and since it is manufactured using a solvent-free type resin composition without using an organic solvent, and has an excellent absorbing and/or fixing property with respect to a water soluble ink, it has environmental friendly advantages.
