摘要:
Liquid toner is supplied onto an image support on which an electrostatic latent image is formed and a developed toner image is transferred to an intermediate transfer body before being transferred and fixed onto a print medium at a transferring/fixing section using a backup roller. The print medium is preheated up to a temperature required for transferring/fixing the toner image before being carried to the transferring/fixing section. The transferring/fixing section is not provided with a heating means and a high pressure in the range of 10-60 kg/cm is set between the intermediate transfer body and the backup roller. Alternatively, the intermediate transfer body is provided with a heating means and the softening temperature of resin for use in the liquid toner is set not higher than the heat resisting temperature of other members, e.g. a photosensitive drum, and the temperature of the intermediate transfer body is set to not lower than the softening temperature of resin but not higher than the heat resisting temperature of other members.

摘要:
The invention relates to a printing machine with an electrophotographic device, comprising a photoconductor, a photoconductor drive and an illumination device. Said electrophotographic unit can be provided with the substrate by a feed device. The photoconductor drive motor is adjusted by means of a controller and the feed device can be linearly adjusted by means of a feed device drive motor. In order to produce high-definition prints, especially images or lettering on plate-shaped substrates, the feed device drive motor is adjusted by means of a controller that is controlled by a master-slave controller via a setpoint feed. The controller for the photoconductor drive motor is also controlled by the master-slave controller via a setpoint feed and the master-slave controller synchronizes the feeding speed of the feed device and the speed of movement of the photoconductor.

The invention concerns a method which consists in using a document electrostatic photocopying system (3) on ordinary paper without fixing furnace, in applying the medium (8) bearing the unfixed copy on the candle surface and in heating it to a temperature providing a superficial fusion of said surface and coloured thermoplastic powder used to reproduce the image on the medium, said coloured powder being thus transferred for the most part on the candle. This method concerns in particular the manufacturing of decorated candles and tapers, for domestic, professional or even religious purposes.
摘要:
A transfer support (10) and a method for fusing a transferable toner image (16) to a face (22) of a digital disc (18). In the method, a transferable toner image is electrophotographically printed onto a transfer layer. The transfer layer has a surface energy insufficient to retain the transferable toner image against a peel force of greater than about 550 Newtons/meter. The transferable image (16) is registered against the face (22) of the digital disc (18) to provide a transfer support-digital disc pair. The transferable image is fused to the face of the digital disc. Registry of the transferable image and the face of the digital disc is maintained during fusing.

摘要:
A printing process for forming high contrast color images on polymer surfaces, comprising: (a) forming a layer of substantially opaque liquid toner comprising polymer based toner particles and a carrier liquid, on an imaging surface; (b) transferring the layer to an intermediate transfer member; (c) heating the layer on the intermediate transfer member to a temperature at which the toner particles at least partially coalesce; (d) repeating (a) to (c) sequentially for at least one subsequent layer in at least one color, said at least one subsequent layer being transferred to the intermediate transfer member onto the opaque layer to form multiple layers on the intermediate transfer member; and (e) transferring the multiple layers to a polymer surface.
摘要:
A method and the apparatus to perform the electrostatic transfer of a developed image from a permanent master (48) to a receiving surface (23) are provided whereby in a first generally horizontal direction the image is charged and developed and in an opposing second direction the developed image is transferred to a receiving surface (23) and the master (48) is cleaned. The master (48) is electrostatically picked up and retained on flexible carrier means (40) which are first moved in the first direction prior to the image transfer and then traversed by a transfer roller (45) moving in the opposing second direction to effect the electrostatic pickup.
