Patent number: 6495984Abstract: The present a step controller includes a switching circuit having at least two outputting states, especially a three-level switch (DPS1) with negative feedback, and a PI or PID controller having an integrator (I1). The integrator is inactive during the positioning pulse of the three-level switch. The integrator (I1) is provided with a correcting element (CORR) which reduces the reset time (Tn) for a large input signal (xd). In this way, linear behavior of the step controller can be attained over the entire positioning range of a positioning element.Type: GrantFiled: August 20, 2001Date of Patent: December 17, 2002Assignee: Siemens AktiengesellschaftInventors: Karl-Heinz Kirchberg, Dieter Mohr

Patent number: 6057077Abstract: The invention relates to a process for the production of a colored image for color proofing of copy masters for multicolor printing and a layer material for carrying out this process.A positive image of the exposure mask (color separation film) is produced by lamination of a photosensitive material onto a colored layer material, followed by imagewise exposure and peeling-off of a film support, or a negative image of the exposure mask is obtained by imagewise exposure of the photosensitive material before the lamination, accompanied by flood exposure after lamination followed by peeling-off of a film support. The two procedures use the same materials and do not require wet development. For each single-color image, only one lamination step is required.Type: GrantFiled: June 25, 1998Date of Patent: May 2, 2000Assignee: Agfa-Gevaert N.V.Inventors: Karin Marz, Dieter Mohr

Patent number: 6007960Abstract: A process for producing a colored image by laminating a light-sensitive material comprising a temporary support film (i), a colored light-sensitive layer and a heat-activable adhesive layer onto an image-receiving material at elevated temperature and under pressure, subjecting the light-sensitive layer to imagewise exposure and developing by peeling off the support film, characterized in that the image-receiving material comprises a light-sensitive compound which, on irradiation, releases a gas which remains trapped in the image-receiving material in the form of gas bubbles. The advantage of the process is that, on irradiation under a halftone original, the size of the halftone dots in the coloured image produced on such an image-receiving material is optically reduced.Type: GrantFiled: April 16, 1997Date of Patent: December 28, 1999Assignee: Agfa-GevaertInventors: Karin Marz, Dieter Mohr, Dieter Bodenheimer, Manfred Hilger

Patent number: 5976757Abstract: The present invention relates to a development material by means of a latent, colored image, obtained by laminating another, photopolymerizable material colored in a primary color onto an image-receiving material, peeling-off the film support and exposing the material under the associated negative color separation film, can be developed by laminating the development material onto the latent image and then peeling-off the development material together with the non-image areas. The invention also relates to a process for the production of a color proof using this development material in combination with photopolymerizable materials in the various primary colors.Type: GrantFiled: July 8, 1998Date of Patent: November 2, 1999Assignee: Agfa GevaertInventors: Martin Benzing, Dieter Mohr, Jurgen Mertes, Holger Schembs, Andrea Travers-Hemmer, Daniela Clausen, Karola Kaufhold

Patent number: 5922508Abstract: The invention describes a photopolymerizable recording material which comprises a photopolymerizable layer and a cover layer. The cover layer comprises a polymer which possesses low permeability to atmospheric oxygen and is soluble in water, and a water-soluble dye which absorbs light in the region from 300 to 700 nm and within this range has a non-absorbent region corresponding to the emission range of the copying light source.The material can be sensitized for various spectral regions, for example, for UV light, visible light or laser light and has a higher resolving power than a corresponding material which does not contain a dye in the cover layer, while its photosensitivity remains unchanged or is only slightly reduced.Type: GrantFiled: November 25, 1997Date of Patent: July 13, 1999Assignee: Agfa-Gevaert AGInventors: Rudolf Zertani, Dieter Mohr, Werner Frass

Patent number: 5800962Abstract: A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing.Type: GrantFiled: May 1, 1997Date of Patent: September 1, 1998Assignee: Agfa-Gervaert AGInventors: Martin Benzing, Dieter Mohr, Juergen Mertes, Peter Blum
