Abstract:
A printing method in a printing press includes zonally metering a printing ink at a first viscosity with a metering device and transferring the printing ink at a second viscosity with a printing form cylinder, in which the second viscosity is greater than the first viscosity. An offset printing unit for implementing the method is also provided.
Abstract:
A roller microcontact printing device and a printing method of the device are revealed. The roller microcontact printing device includes a transfer module with a transfer roller and a supply module. The supply module provides an isolating solution and a thin film material to the transfer module to form an isolation layer and a thin film layer in turn on the surface of the transfer roller. Then the thin film is transferred to a substrate by the transfer roller. The microcontact print device and method are used in a roll-to-roll printing process. Thus the production efficiency of the thin film layer on the substrate is improved and the cost is reduced.
Abstract:
A printing method comprising a process of forming an ink pattern on a silicone rubber blanket having a plate function, or a process of forming an ink pattern from a uniform ink on a silicone rubber blanket having no plate function, a process of transferring the pattern to a substrate, and a process of forming a uniform ink on a silicone rubber blanket having no plate function, pressing the uniform ink against on the ink pattern formed on the substrate, and laminating a uniform ink on a portion thus pressed, only on the ink pattern.

Abstract:
A flexible medium for a scrolling color changer and method of making thereof. The medium is made by applying an ink using a Meyer Rod which has varying cell lengths along its length. This leaves varying size cells of ink at different locations along the length of the medium. The ink has special characteristics whereby its evaporation rate and viscosity are carefully controlled. The viscosity is such that an amount of levelling will occur will be equal to the distance between any cells, but that cell to cell levelling will not, in general, occur.
Abstract:
An object is to provide a printing apparatus or the like that improves printing accuracy when a carriage moves back and forth for printing. A block 51 on a block surface plate is mounted on the block surface plate at a predetermined location. On the other hand, a substrate 54 on a print surface plate is mounted at a location corresponding to the location of the block 51, that is, a location where a picture transfer is desirably received from a blanket cylinder 13. In the present invention, the arrangement of sliders 52 and 40 for the block carriage 50 and a printing carriage 7 to reciprocate along two rails 30 in the block carriage 50 and that in the printing carriage 7 are the same. With such an arrangement, at the same location immediately below the blanket cylinder 13 on the same track 30, even when the straightness of the rail 30 is not sufficient, the block 51 and the glass substrate 54 take the same position at the location, and thus print misalignment can be prevented.
Abstract:
In a process for producing a printed design creating 3D visual effect, a compound consisting of a printing ink blended with magnetic particles is used. The printing ink containing the magnetic particles is applied onto a printing plate on a printing apparatus, and a tool capable of producing a required magnetic force is positioned at a predetermined area of the applied printing ink, so that the magnetic particles in the printing ink are attracted and gathered to form ups and downs in the area and create a 3D visual effect.
Abstract:
A print structure includes a pattern layer that selectively actuates one or more of a plurality of actuators to selectively form one or more wells in a print surface to create a defined pattern on the print surface. A material is applied to the one or more wells and subsequently transferred to another surface in order to transfer the pattern.
Abstract:
A smart surface is composed of a semiconductor memory layer overlaid on an insulated conductive layer with a one to one correspondence of each memory cell with the conductive pad on the insulated layer. The entire structure can be fashioned into a either a planar structure or other geometric structure. An appliance may be overlaid the smart surface and signals transmitted and received to and from the appliance via the conductive pad(s) of the smart surface.
Abstract:
A litho printing press comprising one or more litho ink printing stations, each of which has paste-type, oil-based litho ink applicating means for depositing said oil-based litho ink onto a printing plate, an adjacent first rotatable cylinder called the plate cylinder on which is clamped a non-planar, laminate multiple layer flexible printing plate which receives said oil-based litho ink from the ink applicator means in a nip therebetween, and at least a second rotatable cylinder called the impression cylinder over which passes the substrate to be printed upon in a nip between the substrate and either the plate cylinder or another and intermediate rotatable cylinder called the blanket cylinder. This results in elimination of dampener and the dampening solution. The non-planar multiple layer flexible printing plate has an outermost layer for receiving the litho ink after it has been adhesively secured in the pre-press department of the printing plant to an innermost layer of a different material. The outermost layer is a see-through translucent or transparent synthetic plastic. The different material of the innermost layer can be either a synthetic transparent plastic or an imaged metal plate. In the pre-press department of the printing plant the outermost layer is cut through to the innermost layer manually or by a CAD-CAM machine to provide spaced cut-out areas with adjacent projections which receive the oil-based litho ink and then deposit said ink directly or indirectly on a substrate. The elimination of the dampening solution and the dampener from the print station by the non-planar laminate multiple layer flexible body printing plate, called a “Mike Plate” or “Modified Mike Plate” clamped on the plate cylinder makes possible a litho printing press without a blanket cylinder. That is, a litho printing press with only two cylinders per print station instead of three, and wherein said “Mike Plate” or “Modified Mike Plate” clamped on the plate cylinder prints directly upon the substrate, sheetfed or webfed. All this is done at low cost with less downtime on-press, and with significantly less waste and spoilage and other attendant benefits all of which contribute to quicker delivery of jobs by the printer to his customer.
