| 20090322811 | INKJET PRINTING SYSTEM - An inkjet printing system comprising a plurality of static inkjet printing units each comprising at least one inkjet printing head; an ink-receiving element comprising a poorly-absorbing or impermeable substrate; an aqueous inkjet composition which comprises a polymeric compound comprising discrete particles responsive to an external stimulus, and a functional material, which may be incorporated as part of the polymeric particles, the composition having a first rheological state and a different second rheological state in response to a stimulated change in conditions, the first state being associated with a first lower viscosity of the composition, wherein the particles have a first lower volume, and the second state being associated with a second higher viscosity of the composition, wherein the particles have a second higher volume, and of drying the aqueous ink composition only positioned downstream of the plurality of the printing units. | 12-31-2009 |
| 20100068387 | INK FOR PRINTING ON LOW ENERGY SUBSTRATES - The invention provides an aqueous inkjet ink composition comprises a polymeric compound comprising discrete particles responsive to an external stimulus, and a functional material, wherein the functional material may be incorporated as part of the polymeric particles, the particles causing the composition to have a first rheological state and a different second rheological state in response to a stimulated change in conditions, the first rheological state being associated with a first lower viscosity of the composition, wherein the particles have a first lower volume, enabling the composition to pass through an inkjet printhead orifice and the second rheological state being associated with a second higher viscosity of the composition, wherein the particles have a second higher volume, enabling immobilisation of droplets of the composition on a substrate. The inkjet composition is particularly useful in a continuous inkjet printing system for printing onto a wide range of surfaces including impermeable surfaces. | 03-18-2010 |
| 20100159394 | METHOD OF MAKING A PLANOGRAPHIC PRINTING PLATE - The invention relates to a method of making a planographic printing plate comprising a substrate having thereon one or more layers of a radiation-sensitive metal oxide, sulfide or nitride and excluding an organic hydrophobic material or a binder within or above a radiation-sensitive layer, the method comprising depositing the one or more layers of the radiation-sensitive metal oxide, sulfide or nitride by vapour deposition and exposing the one or more layers without that exposure causing ablative effect. Preferably the compound, and in particular a metal oxide, such as titanium dioxide, is deposited by atomic layer deposition at atmospheric pressure and at a temperature of from 20° C. to 300° C. at a layer thickness of less than 100 nm. The substrate can be any planar material, preferably with the potential to be flexible and with a surface that can be roughened or textured. No binder is required to adhere the metal compound to the printing plate and no processing or chemicals are required in the preparation of the plate. | 06-24-2010 |
| 20100159395 | METHOD OF DIFFERENTIATION OF UNEXPOSED AND EXPOSED PLANOGRAPHIC PRINTING PLATES - The invention relates to a method of differentiating an unexposed planographic printing plate from an exposed planographic printing plate by means of making a planographic printing plate comprising a substrate having thereon one or more layers of aluminum oxide, and one or more layers of radiation-sensitive titanium dioxide coated thereon and excluding an organic hydrophobic material or a binder within or above a radiation-sensitive layer, the method comprising depositing at least the one or more layers of titanium dioxide by vapour deposition and exposing the one or more layers to radiation without that exposure causing an ablative effect. | 06-24-2010 |
| 20110039025 | METHOD OF PATTERNING VAPOUR DEPOSITION BY PRINTING - A method of creating a patterned coated layer on a substrate comprises the steps of applying a pattern on the substrate by an additive process using a first material, depositing a second material by vapour deposition over the whole substrate area and mechanically removing the pattern of first material from the substrate, leaving the inverse pattern of the second material. | 02-17-2011 |
