The present invention relates to an ink-jet printing method of overprinting a first ink and a second ink on a low-liquid absorbing printing medium, in which the first ink and the second ink are respectively in the form of a water-based ink containing a colorant (A), a polymer (B), an organic solvent (C) and water, and satisfy the following formulae (1) and (2), said ink-jet printing method including the steps of forming characters or images using at least one ink as the first ink, and then forming a background image using the second ink such that the background image is superimposed on at least a part of the characters or images formed by the first ink: [T.sub.2−T.sub.1]<0 mN/m (1); and [V.sub.2−V.sub.1]≥1.0 mPa.Math.s (2) wherein T.sub.2 is the static surface tension of the second ink; T.sub.1 is the static surface tension of the first ink; V.sub.2 is the viscosity of the second ink as measured at 32° C.; and V.sub.1 is the viscosity of the first ink as measured at 32° C. According to the method of the present invention, it is possible to obtain good printed characters or images that are excellent in uniformity of solid image printing and suffer from less intercolor bleeding.

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.

A print method includes applying a first processing fluid comprising water and a lubricant to a fabric, applying a second processing fluid comprising water and a flocculant to the fabric, and applying an ink to the region of the fabric where the first processing fluid and the second processing fluid have been applied.

A method pretreats a printing material used for ink printing to influence the spreading of ink print dots on the printing material. The spreading behavior is influenced in such a way that the ink print dots spread in an anisotropic way. The anisotropic spreading advantageously allows undesired quality losses in the print that are caused by a failed ink nozzle to be reduced or avoided. The influencing of the spreading behavior may be achieved by an anisotropic application of a liquid, in particular a primer or varnish, to the printing material, or by an anisotropic embossment or print on the printing material or by an anisotropic treatment of the printing material with charged particles, in particular by a plasma or a corona, or with electromagnetic radiation, in particular laser radiation.

Provided is an ink jet printing method including: subjecting a printing medium to corona discharge treatment; and applying an ink containing an anionic pigment to a surface of the printing medium subjected to the corona discharge treatment, wherein the corona discharge treatment has a discharge quantity of 3,400 W.Math.min/m.sup.2 or more.

An object of the present invention is to provide a precoat liquid which can prevent the penetration of an actinic radiation-curable ink into a recording medium and which is less likely to damage the texture of the recording medium. A precoat liquid, capable of achieving the object, for an actinic radiation-curable ink includes a hydrophilic polymer, a hydrophilic solvent, water, and resin fine particles. The amount of the hydrophilic polymer is 1 part by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the hydrophilic solvent.

The present invention relates to a baking tray (20) or baking grid, in particular a baking tray (20) for a cooking appliance (1), having a non-stick and/or non-wetting coating (12) obtainable by a process characterised by the following steps, a) providing a baking tray (20) or baking grid having a surface, in particular having an upper surface (7a) and a bottom surface (7b), b) preferably, pretreating of the surface (7a, 7b) of the baking tray (20) or baking grid at least partially, in particular completely, for providing a surface having a roughness being suitable for applying a non-stick and/or non-wetting coating (12) by mechanical treatment, physical treatment or chemical treatment, in particular by sandblasting and/or laser treatment and/or a surface activation treatment, particularly a plasma treatment, and/or an enamelling process to form a ground layer (13), c) applying the non-stick and/or non-wetting coating (12) to the pretreated surface (7a, 7b) of the baking tray (20) or baking grid or a surface (14a) of the ground layer (13), wherein the non-stick and/or non-wetting coating (12) comprises at least one layer (17) that is obtained by a sol-gel process from a first composition comprising a silica sol and a silane. The invention further relates to a cooking appliance (1), in particular a domestic oven comprising such a baking tray (20) or baking grid and a method for manufacturing such a baking tray (20) or baking grid.

A coiled metal substrate with a faux galvanized surface appearance. The faux galvanized surface of the substrate including a spangle print pattern of polyvinylidene fluoride (PFDV) flexographically applied to the metal substrate. Atop the PFDV print pattern is semi-transparent coating of fluoroethylene vinyl ether (FEVE) flexographically applied atop the spangle print pattern of PFDV.

Provided is an object to be printed which can improve the quality of a printed image in inkjet printing on the object to be printed, regardless of the resolution of an inkjet image. In a method for producing an object to be printed having an area to be printed on a surface thereof, a surface of the area to be printed is adjusted so that the area to be printed has a surface energy E (mN/m) of 30 or more and 50 or less. The object to be printed is selected from a can and a film for containers.

A method for creating colorful patterns on a metal surface by using colorless ink is revealed. First carry out a first anodizing process on a metal substrate to form a first anodic oxide layer on a surface of the metal substrate. Then coat a layer of colorless ink on the first anodic oxide layer on the surface of the metal substrate to form a colorless ink pattern mask. Later perform a second anodizing process to form a second anodic oxide layer on a part of the metal substrate without being covered with the colorless ink pattern mask. Next remove the colorless ink pattern mask and coat a metal film over the first anodic oxide layer and the second anodic oxide layer to get a colorful pattern on the metal substrate.
