Patent Number Title Of Patent Date Issued
4812913 Diaphragm arrangement for opto-electronic scanning of originals March 14, 1989
Diaphragm arrangement for point-by-point electro-optical scanning of originals, whereby the scan point is composed of a central main field and of a surrounding field surrounding the main field. A diaphragm for scanning the main field and a second diaphragm for scanning the surroundin
4564859 Method and an apparatus for producing color separations for single color printing January 14, 1986
A method and apparatus for producing color separations for single color printing in electronic reproduction, for example in textile, decorative, or packaging printing. A colored master is optoelectronically scanned point-by-point and line-by-line to obtain color signals. Color recognitio
4521812 Method of improving contrast accentuation June 4, 1985
This invention relates to a method for improving contrast accentuation in the case of the re-recording of originals in the sphere of electronic image processing by means of graving devices and scanners. An image signal is obtained by scanning an original opto-electronically dot-by-dot an
4414635 Method and circuit for recognition of colors November 8, 1983
An apparatus and a method for the recognition of colors on a colored image illuminated with a light source of a known spectrum composition, wherein the intensities of three primary colors are measured opto-electronically as color components, which represent the spatial co-ordinates of th
4403249 Apparatus for mixing image signals to obtain a printing master September 6, 1983
In an apparatus and a process for obtaining image signals, and electronically mixing the image signals to generate mixed signals, the steps include modulating one of the image signals with the control signal, amplitude-inverting the control signal, modulating the other image signal w
4293872 Production of printing blocks or forms October 6, 1981
This invention relates to the production of a printing block or form of the kind in which at least one original is scanned optoelectronically to obtain image signals being mixed to generate a composite signal and is recorded as the printing block or form, one of the image signal which is
4261011 Color separation production using color recognition circuit April 7, 1981
The invention relates to a method for producing line and continuous tone color separations of pattern models of textile, decoration or packaging printing and the like, and further relates to a color scanner. A characteristic color recognition signal for controlling the recording is o
4255761 Apparatus for mixing image signals to obtain a printing master March 10, 1981
In an apparatus and a process for obtaining image signals, and electronically mixing the image signals to generate mixed signals, the steps include modulating one of the image signals with the control signal, amplitude-inverting the control signal, modulating the other image signal w
