摘要:
A method for forming tactile images or a combination of tactile images and regular images, on a flexible packaging substrate comprising depositing an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant directly onto a flexible packaging substrate or depositing the ink onto an intermediate transfer member, in an image area to form a tactile image area or a combination of tactile image area and regular image; forming the tactile image by depositing multiple layers of the ink in locations of the tactile image or portion thereof; when an intermediate transfer member is used, transferring the deposited ink from the intermediate transfer member to the flexible packaging substrate; and curing the ink.
摘要:
An ink jet printing device including an ink jet print head and a print region surface toward which ink is jetted from the ink jet print head, wherein a height distance between the ink jet print head and the print region surface is adjustable; wherein the ink jet print head jets an ultra-violet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer, or prepolymer; a photoinitiator; a reactive wax; and a gellant; wherein a print deposited upon the print region surface is Braille, raised print, or a combination of regular print and one or both of Braille and raised print.

A small home/office tactile printing system comprises a print head assembly and a paper feed assembly. The print head assembly includes a print head for printing with ink and an applicator for applying a liquid. The paper feed assembly moves paper (or any other medium suitable for printing) relative to the print head assembly and its components for printing the ink on the paper, applying the liquid to the medium and curing the liquid. The liquid is ultraviolet (UV) curable glue and curing is exposure of the UV liquid to UV light. The present invention also includes a variety of methods including a method for printing tactile information, a method for copying a document having tactile printing, a method for binding sheets of a media, a method for scratch-off printing and method for copying a bound document.

A method to help control the quality of printed three-dimensional objects is provided. The method may include dispensing building material in consecutive slices using a building material dispensing head which dispenses material in the printing X direction; and combining printing of two or more consecutive slices to provide high resolution printed layer in the non-printing Y direction, according to a high resolution pixel map.

The invention provides a method for patterning coatings which includes the steps of: a) applying coatings onto a flat plate; b) allowing the coatings applied to the flat plate to contact with protrusions of a substrate so as to transfer portions of the coatings on the flat plate which contact with the protrusions of the substrate to the protrusions of the substrate from the flat plate, the substrate having unevenness formed with the protrusions and grooves; and c) allowing the coatings remaining on the flat plate or on the protrusions of the substrate to contact with a print surface of a print object so as to transfer the coatings to the print object. The method has simple processes, and ensures high precision and high speed in patterning functional materials, preferalby, electronic materials.

The invention provides a method of producing a security feature in an identification document. A core including a top surface and a bottom surface is provided. A first laminate is laminated in contact with the top surface. A second laminate is laminated in contact with the bottom surface, the laminated core comprising the identification document, the identification document having a top side and a bottom side respectively corresponding to the core's top and bottom side. A pattern is laser etched into the top surface of the identification document.
摘要:
A method for creating raised and special printing effects using inkjet technology is provided. The method includes the steps of depositing a light curable photo-polymer material (18) on the area selected for the printing effects and curing the area. The amount of material to be deposited corresponds to the area selected for the printing effects and the height of the raised area relative to the medium (22) on which the photo-polymer material (18) is deposited.
摘要:
A 3D object molding apparatus has a tank holding an uncolored or white resin as a first material for use in molding an interior of a 3D molded object and other thanks holding colored resins as second materials for use in molding a surface of the 3D molded object. A control unit moves a nozzle head in the XY plane and controls jetting of resins from injection nozzles of the nozzle head. When molding an interior of the 3D molded product, at least the first material is jetted and when molding a surface of the product, at least the second material is jetted. The apparatus has coloring nozzles to jet predetermined coloring agents in molding the 3D molded product to achieve coloring of the 3D molded product in the molding process.
摘要:
A method of forming a three-dimensional feature on a surface using the technique of drop ejection to deposit droplets of deposition material. The method comprises depositing a plurality of droplets on the surface to form a feature comprising multiple discrete portions, adjoining portions being formed from different deposition material. Examples of such a feature include a Braille character and a multi-layer optical device.
摘要:
Hiragana characters and Chinese characters, as well as a Braille pattern, are formed on a thermal expansile sheet by the use of a thermal transfer ribbon by a thermal transfer unit. When only the portions of the thermal expansile sheet corresponding to a Braille pattern is exposed to light, only portions of the thermal expansile sheet corresponding to the Braille pattern are raised, whereby a Braille pattern is produced and the characters remain flat. The characters represent the meaning of the Braille pattern and function to discriminate the orientation of the thermal expansile sheet. Thus, it becomes easier for those who have no knowledge of Braille to discriminate the orientation of the sheet where Braille is formed.
