摘要:
Apparatus and methods for controlling application of a substance to a substrate involve the use of one or more gating agents that block the substance from or attracts the substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the gating agent directly to the substrate or to an intermediate surface. The substance may be an ink, an electrically conductive material, a magnetic material, a carrier for a therapeutic, diagnostic, or marking substance other than an ink, a carrier or any other substance.
摘要:
A method of producing and distributing printed product applies aqueous solution to a print medium to define non-image and image areas of the print medium, and contacts the non-image area and the image area with ink. Ink is transferred substantially only to the image area of the print medium to produce the printed product. The printed product is distributed to an end user.
摘要:
A method of printing a printed output of a press comprising ink on a print medium applies ink to a surface, places individually controlled drops of aqueous solution onto the print medium in a drop pattern, and transfers ink from the surface to areas of the print medium that are free of aqueous solution to produce the printed output of the press. A method of variable printing is also disclosed.
摘要:
A variable lithographic printing process includes absorbing a release agent into an imaging member; forming a later image by evaporating the release agent from selective locations on an imaging member surface; developing the latent image; and transferring the developed image to a receiving substrate. The release agent diffuses through the imaging member surface.
摘要:
A system and method are provided that incorporate a multi-layer plate configuration for a Digital Offset Plate (DOP) including at least a robust top imaging layer and a bottom layer that acts as a reservoir for the releasing oil in a proposed variable digital offset lithographic architecture. The top imaging layer may contain a small amount of oil (
摘要:
Different solvents for a dampening fluid are disclosed. The solvent is a volatile hydrofluoroether liquid or a volatile silicone liquid. Such liquids have a lower heat of vaporization, a lower surface tension, and better kinematic viscosity compared to water, which is the conventional solvent used in dampening fluids. The dampening fluids, which are relatively nonpolar, can be used in a combination with polar inks to form a new type of digital lithographic printing system.
摘要:
A method for printing a print medium applies ink to a surface and ejects drops of an aqueous solution onto the print medium to define image and non-image areas. The ejection of each drop is individually controlled. Ink from the surface is transferred to the image areas of the print medium. Methods of printing on a web and for printing a printed sheet output of a press are also disclosed.
