Abstract: A golf ball having a mark with a distinct appearance unrealizable by only changing in tint. Ink can be prepared by mixing one or more components which provide luster such as pearl particles, shell particles, mica particles and the like in an ink medium. Therefore, ink can be used for marking the surface of the golf ball by an indirect printing used with a transfer printing film or a direct printing such as a pad printing, a screen printing and the like. The composition of the ink is 5 to 150 parts by weight of the mica, pearl particles and the like. The mica, the pearl particles and the like are employed for flat forms.

During printing operation, each surface areas of the rotating cylinder continuously undergo the cycle of coating, imagewise exposure, optionally developing, inking, printing of inked images to the receiving medium, and optionally erasing processes. The developing means can be omitted if an ink and/or fountain solution developable photosensitive layer is used. In an alternative design, the cylinder is replaced with a continuous supply of a ribbon with lithographic substrate surface. In another alternative design, the cylinder and the coater are replaced with a continuous supply of a pre-sensitized ribbon comprising on a substrate a photosensitive layer.

Abstract: A method for loading and unloading substrates on a drum of an imaging engine is applicable to the loading of plates in a platesetter. The method comprises unclamping a trailing edge of a first substrate of the drum and clamping a header of a second substrate to the drum. The order in which these two steps are performed is not critical to the invention. For example, the clamping and unclamping can happen simultaneously. Alternatively, the unclamping of the trailing edge can occur before the clamping of the header, or visa versa. In any case, the drum is then rotated to eject the first substrate from the drum while installing the second substrate on the drum. The notion here is that, as the drum is rotated, one substrate is being ejected while a second substrate is being installed on the drum. Thereafter, the header of the first substrate is unclamped and the trailing edge of the second substrate is clamped to the drum.

Abstract: 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.

Abstract: An ink supply controller capable of generating a proper ink curve from a result of printing even when there is a small difference in image area percentage between ink key regions is provided. The ink supply controller includes an old job data storing element for storing old job data; a new job data acquiring element for acquiring new job data; an ink curve generating element for generating an ink curve based on the old job data and the new job data; an ink curve display element for displaying the generated ink curve; and an updating element for updating the old job data by using the generating ink curve. The ink curve generating element acquires data parameters for generation of the ink curve from both the old job data and the new job data to set an approximate curve obtained from a distribution of these data parameters as a new ink curve.

Abstract: A guide strip removal system includes a pair of guide strip removal devices positioned on opposite sides of a printer outlet where a continuous sheet of paper is discharged. The guide strip removal devices each include a pair of plate members secured together in a spaced apart parallel relationship to define a narrow slot therebetween. The plate members each have a corner portion delineated from a planar main body portion by respective narrow slits that extend from front edges of the plate members toward rear edges thereof. The corner portions are angled away from the main body portions to create paths for the side edge guide strips that diverge abruptly away from paths for the marginal side edge portions of the printer paper. The side edge guide strips are thereby removed from the marginal side edge portions of the, paper without the use of any moving parts or cutting blades.
