The present invention relates to a pre-treatment liquid providing improved spreading property when printing an ink-jet image, as well as an ink-jet printing method comprising applying the pre-treatment liquid of the invention on a recording medium prior to printing an ink-jet image and a method of pre-treating a recording medium, comprising pre-treating a recording medium with the pre-treatment liquid of the invention. With the present pre-treatment liquid a combination an improved spreading of the ink on the pre-treated recording medium can be achieved.

Aqueous inkjet primering composition providing both pinning and ink spreading functionality

The invention relates to an ink composition, the ink composition including a pinning agent. The pinning agent provides the ink composition with thermogelling behavior. The invention further relates to a pinning agent suitable for an ink composition. The invention further relates to a method for applying an image to a receiving medium using an ink composition including a pinning agent.

Ink composition, pinning agent and print method

An ink-jet printing method includes printing an image with at least one ink on a recording medium, and applying a cover liquid on the image formed with the at least one ink within 1 s after printing the image with the at least one ink. An ink-jet printing apparatus includes at least one printing unit for printing an image with at least one ink on a recording medium, and an application unit for applying a cover liquid on the image formed with the at least one ink.

Preventing bleeding of multi-color print by in-line jetting

The invention relates to a latex ink composition, the latex ink composition comprising a water soluble resin. The invention further relates to a water soluble resin suitable for a latex ink composition, the water soluble resin comprising a backbone and a stabilizing group, wherein the stabilizing group is capable of forming hydrogen bonds. The invention further relates to the use of a water soluble resin in a latex ink composition.

Ink composition, a method for preparing the ink composition and use thereof, a water soluble resin and use thereof in an ink composition

A cleaning member for cleaning a surface which, for example in an image recording device, is brought into contact with toner powder or an image receiving material carrying toner powder. The cleaning member comprises a surface layer of a high-viscosity polymeric material that is sticky at room temperature. Preferably, the polymeric material is a polymer or polymeric mixture having a viscosity between 10.sup.4 and 10.sup.6 Pa.s at 20.degree. C., and a very suitable polymer is polyisobutylene, having a molecular mass of about 100,000. The cleaning member is preferably provided with mixing means for mixing into the mass of the sticky layer impurities that are deposited on the surface thereof.
