A method of preparing a lithographic printing plate includes the steps printing a liquid on a lithographic support to form a printing area which corresponds to a raster image, wherein the raster image includes a section which has a tone-value from 90% to 100%, and the jetted liquid droplets for this section, on a corresponding part from the printing area on the lithographic support, are contactless with each other.

An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

A method of preparing a first and second lithographic printing plate for lithographic printing of a color digital image on a receiver wherein the color digital image includes a plurality of colorant separations; the method including the steps of jetting droplets by an inkjet CTP system on a first lithographic support for the first lithographic printing plate thereby forming a printing area of a first lithographic image which represents a first colorant separation of the plurality of colorant separations; and jetting droplets by the inkjet CTP system on a second lithographic support for the second lithographic printing plate thereby forming a printing area of a second lithographic image which represents a second colorant separation of the plurality of colorant separations; and wherein the method of preparing a first and second lithographic printing plates is characterized by forming a part of or whole the first and second lithographic image in a print pass by the inkjet CTP system.

A method is disclosed for calibrating a deposition rate in an aerosol jet printer. The method includes providing a substrate defining an array of wells, each defining a volume. The method also includes defining a toolpath such that a dispensing nozzle passes over the wells. The method also includes defining a dwell time such that the nozzle remains centered above each well for an amount of time equal to the dwell time, after which the nozzle follows the toolpath to be centered over the following well. The dwell time defines a deposition rate based on the volume of the wells. The method also includes causing the nozzle to move along the toolpath, depositing material into the wells. The method also includes observing one of overfilling and underfilling and adjusting dispensing parameters to effect a modified deposition rate, until the wells are being filled to within a tolerance of exactly full.

A method for making a lithographic printing plate by direct-to-plate recording includes the step of image-wise deposition of a hydrophobic coating by microplasma onto a hydrophilic support or a support provided with a hydrophilic layer.

A method of preparing a first and second lithographic printing plate for lithographic printing of a colour digital image on a receiver wherein the colour digital image includes a plurality of colorant separations; the method including the steps of jetting droplets by an inkjet CTP system on a first lithographic support for the first lithographic printing plate thereby forming a printing area of a first lithographic image which represents a first colorant separation of the plurality of colorant separations; and jetting droplets by the inkjet CTP system on a second lithographic support for the second lithographic printing plate thereby forming a printing area of a second lithographic image which represents a second colorant separation of the plurality of colorant separations; and wherein the method of preparing a first and second lithographic printing plates is characterized by forming a part of or whole the first and second lithographic image in a print pass by the inkjet CTP system.

An imaging blanket comprises a base comprising an elastic polymer and sulfur. A barrier layer is on the base and a surface layer is on the barrier layer. The surface layer comprises an elastomer and a platinum catalyst.

A method for operating a printing device and an image generation kit are disclosed. The image generation kit is adapted to controllably eject individual drops of a gating agent, and is operating the image generation kit in synchronism with a principal substance application apparatus to deposit the drops of the gating agent on a substrate and to transfer a principal substance to the substrate. The drops of the gating agent on the substrate define image and non-image areas of the substrate, the image and non-image areas of the substrate are undefined until the drops of the gating agent are deposited thereon, and the substrate with the principal substance transferred to the image areas is an end product of the printing device.
