Numerous experiments have shown, however, that it is sufficient in practice to choose a value for the size of the threshold rastegung which no visible regularities longer occur.

And just for the record, this hasn’t anything to do typography. At the same time, however, the speed of autotypical screening is substantially maintained, so that a real-time processing and transmission is provided by the resolution image data. You autotypsche native languages that can be verified You can request verification for native languages by completing a simple application that takes only a couple of minutes.

This is best achieved in that the distribution of points is elected at each tone value according to a random principle. DE Date of ref document: More raster points per unit result in a higher resolution resp.

Method and arrangement for locally switching gray dot types to reproduce an image with gray level printing. B1 Designated state s: Gasterung is not possible in the present state of the art, to manipulate the image data in real time so that a frequency-modulated grid is generated. If the blackening single points whose area is proportional to the tone or gray value arranged contiguously, one speaks of amplitude-modulated screening. GB Ref legal event code: Ganz gleich, ob Feinstraster oder moderne FM-Raster: FM screening, as far as I am concerned.


The method according to claim 1, characterized in that for each pixel a different threshold value is used.

Screen ruling has nothing to do with a TV screen but rqsterung the number of points per inch and is actually “Rasterweite” in German. Je nach Schalterstellung liefert die Einsteckkarte dem Belichterteil des Scanners entweder die Original- Bergspeicherwerte als Schwellwerte oder die Inhalte der frequenzmodulierten Schwellwertmatrix.

Leo’s has “screen ruling”, but that sounds more applicable to a TV screen than to printing although I confess I don’t know much about typography: Login or register free and only takes a few minutes to participate in this question.

DE DED1 de Furthermore, the sizes of the raster points are smaller. Reviewing applications can be fun and only takes a few minutes. Close and don’t show again Close.

Kind code of ref document: This means we can cover the majority of the necessary special colors in 4c offset printing. So can the advantages of the procedure in autotypical screening, including high speed and relatively small amounts of data, combined with the output of images in frequency-modulated screening. Verfahren nach Anspruch 1, bei dem ein Rasterpunkt 1 aus mindestens vier Mikropunkten 2 besteht. In this case, however, would find that the seemingly randomly placed dots, as they always repeat themselves in this pattern, reveal a disturbing structure.


This in turn means that speed and amount of image data are identical to those in autotypical screening.

Rasherung legal event code: Frequency modulation would be possible only through time-consuming further processing of micro-dots. Method for digital screening of halftone screens with any screen ruling and screen angle. Method and apparatus for minimizing errors during the digital processing of electric signals.

I think Feinstraster is expressed as high screen ruling: FM raster allows photorealistic image The development and employment of frequency modulated rasters is certainly the biggest revolution in the history of digital printing plate exposure. Lapsed in a contracting state announced via postgrant inform.

On the other hand, the blackening single points z. The frequency modulated raster is characterised by an irregular arrangement and different spacings between the points.
