Device and method for reproducing originals onto light-sensitive material |
March 14, 2000 |
| A method and a device for reproducing originals onto light-sensitive materials is described where unsharp masks for changing the reproduction process or the density values to be reproduced are determined from the density values of the original and from pre-specified gradation factors. |

Method of copying transparent originals and photographic copier |
November 2, 1999 |
| Film frames are scanned preparatory to copying and a set of density values is generated for each frame. When a frame exhibits excessive contrast, a mask is calculated using the respective set of density values. The calculated mask is formed on an LCD or LED matrix which is in register |

Reproduction of transparent masters |
September 28, 1999 |
| A copying apparatus is adjusted in order to produce high-quality copies of transparent negatives or diapositives having excessive variations in brightness. The adjustment is performed using a reference master. The apparatus is properly adjusted when a copy of the reference master meets |

Method of reproducing transparent masters |
July 20, 1999 |
| A master to be copied has a picture in which a dark region and a light region are located one behind the other. The two regions are separated by a light/dark transition where a halo can develop on copies of the master. Prior to copying, the master is scanned and the resulting data used t |

Masking of transparencies for copying |
June 10, 1997 |
| A transparency to be reproduced is positioned in register with copy material having respective sensitivity maxima in the blue, green and red wavelength ranges of the spectrum. An illuminating unit for exposing the copy material includes an array of cells such as an LCD. The density of |

Suction apparatus, operated by compressed air, for drawing off dust-laden gases |
June 18, 1996 |
| An apparatus for drawing off dust-laden gases, especially in the art of dental technique, has a ring channel (15) which can be loaded with compressed air. The airstream which is provided by a compressed-air nozzle (26) performs an arcuate movement in the ring channel (15), whereby du |

Masking of photographs for reproduction |
November 14, 1995 |
| The frames of a film are scanned and exposure data, as well as masking data, are calculated for each frame from the resulting measurements. Following scanning, the frames are successively transported to a printing station. As a frame approaches the printing station, a mask is generated |

Production of properly oriented copies of transparent masters |
April 5, 1994 |
| A transparent master is mechanically sensed to detect the emulsion. The master is then advanced into a projection arrangement where a scanner scans the master point-by-point and line-by-line to generate signals containing data on the master. The signals are entered in a memory and el |

Apparatus and method for copying photographic masters at variable magnifications |
September 29, 1992 |
| Light is passed through a negative located in a primary optical path and towards a band of copy material disposed in the path. A reflector is movable into the primary path so as to deflect the light into a secondary optical path. A mat, transparent plate is situated in the secondary path |
