摘要:
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%.

An artificial chamois leather type product is provided with a colour printed decoration on at least one face thereof, that face having material such as polyester chamois material (12) and the cover layer (10, 11), typically of a latex material is highly moisture permeable yet provides wear resistance to the product; the cover material is characterized by being devoid of colouring material which would deleteriously affect a colour printed image (13) printed onto the layer.

A printing apparatus has a take-out shaft and a rolling-up shaft to supply an intermediate transfer ribbon provided with a transfer layer having a first area in a prescribed pattern and a blank and transparent second area, a printer portion to print prescribed data on the transfer layer of the supplied intermediate transfer ribbon, and a transfer portion to transferr the printed prescribed data on an image receiving medium (a passbook) 1 jointly with the transfer layer. The printer portion and the transfer portion are controlled independently in a first mode to cover the entire image receiving medium and in a second mode to cover the image receiving medium by the first area and the second areas.

A printing unit in a lithographic web fed rotary printing press has a plate cylinder and an associated blanket cylinder mechanically coupled via a gear train. A first drive motor drives both the plate cylinder and blanket cylinder. An impression cylinder is associated with the blanket cylinder, the impression cylinder being in rolling contact with the blanket cylinder and being driven by a second drive motor. The web passes through a nip formed between the impression cylinder and the blanket cylinder for printing. A clutch is provided for interrupting a drive connection between the first drive motor and the blanket cylinder, as is a throw-off mechanism for separating the plate cylinder from the blanket cylinder. With the printing unit, the blanket cylinder can remain in rolling contact with the impression cylinder and be friction-driven by the web after the drive connection has been interrupted.

A drive control mechanism for a scanning head which travels along a scan surface and carries out image reading or image writing. The drive control mechanism includes a driving starting position changing device which changes a driving starting position of the scanning head either outside an image reading range or outside an image writing range, under a predetermined condition. Accordingly, phases of vibration periods are shifted and unevenness in density is less visible.

An intermediate transfer recording medium is comprised by providing a transfer portion having a receptor layer on a substrate film. The transfer portion is printed with the image and thereafter transferred on a surface of a transfer-receiving material. In the first aspect of the intermediate transfer recording medium, the transfer portion is provided with plural hologram patterns 21 with a hologram mark 22 allocated to each the hologram pattern. According to the first aspect of the invention, since an image is formed on the receptor layer through positioning process using the hologram mark and then the transfer portion is transferred to the surface of the transfer-receiving material, no joint of a print plate appears in the hologram pattern and accuracy of transfer is remarkably excellent. On the other hand, In the second aspect of the intermediate transfer recording medium, peeling strength required to peel the transfer portion from the substrate film at the time when transferring the transfer portion to the transfer-receiving material is controlled in the range of 10 to 150 gf/inch. According to the second aspect of the invention, any transfer failure such as tail-extension or chip of the transfer portion is not caused.

This invention relates to a method and apparatus for distributing mass copies of text and/or images on a novel medium, namely eggs, by using the eggshell of the egg as an advertising or message-bearing medium. Mass quantities of eggs are imprinted with a promotional image prior to distributing said eggs to consumers. The promotional image can be, for indicative of a modification to the egg's content, or consist of warnings or instructions pertaining to security or emergency matters. The shells of the eggs are imprinted by a method comprising the steps of (1) repeatedly transferring one row of eggs at a time from a carton having M rows of N eggs to N empty egg-receiving cradles until all the eggs in the carton has been transferred, moving the cradles through a number of imprinting stations, imprinting N eggs at each such station with N tampons, and transferring N imprinted eggs at a time into each of the M rows in the cartons.

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.
摘要:
There are provided a method of forming an image on a card and an apparatus therefor, which are capable of properly carrying out printing of an image on a card and protection of the printed image in a simplified manner without changing the size of the card. A card is used which has an ink-fixing layer laminated on a surface of a substrate layer and an ink image-receiving layer peelably laminated on a surface of the ink-fixing layer. An image is printed on the card, while feeding the card, by an ink jet printing method using a sublimable dye ink. The card printed with the image is conveyed to a heating source, and subjected to heat treatment by the heating source to cause diffusion of the sublimable dye ink held in the ink image-receiving layer in the ink-fixing layer, and color development to form an image. The ink image-receiving layer is peeled off the card after the heat treatment.
