摘要： Continuous tone black and white images are duplicated using laser thermal digital halftone printing. A continuous tone black and white image signal is provided by a source such as a medical imaging source. The image signal is screened with a digital halftone screen, such that each pixel of said image signal is represented by a predetermined matrix of micropixels, whereby to produce a digital halftone image signal corresponding to the continuous tone black and white image signal. A master is created by printing the digital halftone image onto a dye ablated medium by means of laser thermal recording. A duplicate of the master is produced by contact printing onto a duplicating medium.

摘要： A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.

摘要： A migration imaging system using a laser-addressable thermoplastic imaging member 10. The imaging member 10 comprises a supporting section 15 and a thermoplastic imaging surface layer 14. A charged, uniform layer of marking particles 24 is deposited on the imaging surface layer 14. An imagewise-modulated laser beam 24 transforms selected volumes of the imaging surface layer 14 in an imagewise pattern to a permeable state. Charged marking particles 42 that overlay a transformed volume then migrate into the imaging surface layer 14, due to an electrostatic attraction to the imaging member 10, so as to be retained. Unaddressed marking particles 56 are cleaned away by particle removing device 20B comprised of a magnetic brush utilizing hard magnetic carrier particles. The imaging member 10, or solely the imaging surface layer 14, may be transferred and bonded to a receiver member such as a drum for use as an exposure mask in a xeroprinting process, or to a receiver sheet 64 to provide a hard copy reproduction. This migration imaging system provides an inexpensive method and apparatus for imaging which generates relatively little waste products.

摘要： A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition caused exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation. A migration imaging method, which does not employ the bleachable composition of the present invention, wherein marking particles are magnetically attracted to the imaging element, is also provided.

The apparatus includes: a magnetic brush having a rotatable multi-pole magnetic core and a stationary outer shell; a developer supply for supplying a magnetic developer powder, consisting of a magnetic carrier particles and pharmaceutical dry powder particles, to the magnetic brush; a print head on the outer shell; a tablet or other pharmaceutical substrate arranged in spaced relation to the print head to define a pharmaceutical powder transfer region through which the substrate can be moved. The print head includes an array of microchannels for forming a plurality of parallel lines of developer in the channels, a corresponding plurality of transfer electrodes located in the microchannels for selectively transferring pharmaceutical powder from the lines to a substrate, driver circuitry for generating and applying transfer signals to the transfer electrodes, a power supply connection for applying power to the drive circuitry, a print signal input connection for applying print signals to the print head, and a logic and control circuit for applying the print signals to the drive circuitry.In one embodiment the width of an individual microchannel print head and the rotating multipole magnetic core is approximately the same dimension as the tablet or substrate to which pharmaceutical powder is to be deposited. In a further embodiment individual microchannel print heads can be arranged along the length of the shell to simultaneously deposit pharmaceutical powder to an array of tablets. In still a further embodiment the microchannel print head is shaped to conform to the tablet or capsule geometry to enhance deposition in three dimensions.In another embodiment the microchannel print head is formed on a silicon substrate onto which are also formed a multiplicity of individual drive circuits connected through separate conductive paths to individual transfer electrodes. In a further embodiment all the microelectronic circuitry necessary for the operation of the integrated microchannel print head is formed on the silicon substrate.
