The invention further provides an ink composition formed of the radiation-curable polymerizable composition, a method for ink jet recording having: ejecting the ink composition onto a recording medium by using an ink jet recording apparatus and irradiating the ejected ink composition so as to cure the ink composition, and a printed material obtained thereby. The invention further provides a method for forming a planographic printing plate having: ejecting the ink composition onto a hydrophilic recording medium by using an ink jet recording apparatus; and irradiating the ejected ink composition so as to cure the ink composition for forming a hydrophobic region, and a planographic printing plate obtained thereby.

Image data obtained through an image sensor is written in a memory. When printing an image, a printing head is driven in accordance with the image data read out from the memory in a line sequential fashion, and is synchronously moved in a sub scan direction, thereby exposing the instant film line by line. The image appears on the exposed instant film as a developing solution is developed by developing rollers while the instant film is advanced out through the developing rollers. Alternatively, the printing head is driven synchronously with the instant film being advanced. Thereby an image is printed at one sub scanning without the need for moving the printing head. The printing head is provided with an array of three color light emitting elements, and three color light beams are simultaneously projected onto the instant film. The electronic still camera is automatically set in an imaging mode when a power switch is turned on, and is switched to a display mode or a print mode as soon as a display mode key or a print mode key is operated. After being switched to the display mode, the electronic still camera is quickly switched to the imaging mode if only a shutter release button is operated.

A paint injector for digital printing in which paint is deposited in metered amounts on a print medium comprises a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and an endless cable disposed around the wheel and the idler. The motor is preferably computer controlled such that the rotation of the wheel and thus movement of the cable is selectively controlled. As the wheel is rotated, paint contained within the paint reservoir coats the cable and is thus drawn by the cable in front of an air stream. The air stream pulls the paint from the cable and carries it toward the print medium. By employing a plurality of such paint injectors into a single print head, each containing a different color of paint, and secured to a computer controlled, movable carriage positioned over the print medium, a digital image can be painted by the print head on the print medium.

An improved method of manufacturing a photosensitive printing element that minimizes relief variation and improves image fidelity. The method involves a step of pre-curing the first (floor layer) of photocurable material prior to depositing an additional layer or layers of photocurable material that may be imaged and developed to produce a desired relief image on the surface of the photosensitive printing element. The photosensitive printing element is then thermally developed by contacting the photosensitive printing element with at least one roll that is capable of moving over at least a portion of the imaged surface of the flexographic printing element to remove the softened or melted non-crosslinked photopolymer. Non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element can be softened or melted by positioning a heater adjacent to the imaged surface of the flexographic printing element and / or heating the at least one roll that contactable with the imaged surface of the flexographic printing element.

An offset lithography printing press and method wherein dampening structure applies a thin moisture layer directly to a blanket cylinder to facilitate separation between the blanket cylinder and paper or other printable sheet material when passing through a nip between the blanket cylinder and an impression cylinder.

The present invention provides a method for image formation, that can yield thermally transferred images which are excellent in various fastness properties even under severe service conditions, and an intermediate transfer recording medium for use in the method for image formation. The method for image formation comprises the steps of: providing an intermediate transfer recording medium comprising a substrate film and a transfer portion provided separably on the substrate film; forming an image on the intermediate transfer recording medium in its transfer portion; transferring the transfer portion onto an object; and, thereafter, again transferring the intermediate transfer recording medium in its next transfer portion once or more onto the object with the image formed thereon. In this case, in the intermediate transfer recording medium, a hologram image is set every at least second image plane, and an image can be formed on the transfer portion having the hologram image. This can offer an advantage that the transfer portion, with a thermally transferable image formed thereon, can be transferred onto an object followed by the superimposition of a transfer portion, to be served as the outermost surface in the final form onto the transferred portion once or more to provide a strong film for protecting the thermally transferred image. Thus, the problems of the prior art could have been solved.

There are provided a printing method in which at least approximately hemispherical portion of a spherical object to be printed can be printed by pressing a pad against the portion one time, and which can prevent an image printed on the spherical object to be printed from being elongated or distorted, and a printing pad used for this printing method. The method for printing on the spherical object to be printed comprises the steps of preparing a hollow printing pad having a transfer surface, the printing pad being configured so that when the transfer surface is pushed, the gas in the hollow part is released to the outside of the printing pad; transferring ink or paint in recesses formed on the surface of a printing plate to the transfer surface of the printing pad by applying the ink or paint onto the surface of the printing plate and by pressing the transfer surface of the printing pad against the surface of the printing plate; and transferring the ink or paint, which has been transferred to the transfer surface of the printing pad, to the object to be printed by pressing the transfer surface of the printing pad, to which the ink or paint has been transferred, against the object to be printed until at least the hemispherical portion of the object to be printed is wrapped by the transfer surface of the printing pad.

A method of varying the ink density of the full tone in printing within a rotary printing machine with an ink application system which can provide a constant quantity of ink which, in spite of constant ink supply from the inking unit, permits control of the full-tone density or adaptation of the raster tonal values in the print. The method includes setting the binary image on a printing plate. A basic raster of raster points, which determines the area coverage of the binary image, is produced on the printing plate for the variable-area image information. The basic raster is then superimposed on a fine microraster in such way that the area coverage of the basic raster is reduced by a percentage which can be set between 0% and 100%.
