Description

Verfahren zur Herstellung einer rasterfreien Teilfläche bei einem Linsenrasterfilm Es ist bekannt und auch vielfach üblich, bei Tonfilmen auf einem bildfreien Streifen des Filmes die Schallaufzeichnungen anzubringen. Bei normalen einfarbigen. Filmen macht die Freilassung eines. bildfreien Streifens keine -Schwierigkeiten. Anders liegen dagegen die Verhältnisse bei Linsenrasterfilmen, wie sie zur Herstellung farbiger kinematographischer Bilder benutzt werden. Wenn hier die Schallaufzeichnung auf der gerasterten Unterlage erfolgt, entsteht ein zusätzlicher Ton infolge der Helligkeitsschwingungen durch die Rasterung.Method for producing a grid-free partial area in a Lenticular film It is known and also widely used for sound films on one image-free strips of film to attach the sound recordings. With normal monochrome. Filming makes the release one. image-free stripe no difficulties. On the other hand, the situation is different in the case of lenticular lenticular films such as those used for production colored cinematographic images can be used. If here the sound recording takes place on the rasterized surface, an additional tone is created as a result of the Brightness oscillations due to the grid.

Es ist bereits bekannt, zur Vermeidung dieses Übelstandes bei gerasterten Filmen einen rasterfreien Streifen vorzusehen, und zwar dadurch, daß bereits bei der Erzeugung der Rasterung ein Teil der Filmfläche nicht mitgerastert wird. Die Herstellung des rasterfreien Streifens auf diese Weise bereitet aber gewisse Schwierigkeiten. Man hat daher weiterhin vorgeschlagen, zunächst den Film ganz zu rastern und dann an den gewünschten Stellen die Rasterung durch Auftragen einer die Rasterungen auflösenden Substanz zu entfernen, während die übrigen Stellen des Filmes durch einen Schutzüberzug abge-, deckt werden. Aber auch dieses Verfahren hat gewisse Mängel, da sich die Tiefenwirkung der aufgetragenen Lösung nicht genau beherrschen läßt, so daß hierdurch und durch den Schutzüberzug Tonbeeinflussungen entstehen können.It is already known to avoid this inconvenience with rasterized Film a grid-free strip to provide, in that already at Part of the film surface is not rasterized when generating the raster. the However, producing the screen-free strip in this way presents certain difficulties. It was therefore suggested that the film should be rasterized first and then the grid at the desired locations by applying a grid that dissolves the grid Remove substance, while the remaining parts of the film through a protective coating to be covered, to be covered. But this method also has certain shortcomings, since the In-depth effect of the applied solution can not be controlled exactly, so that this and the protective coating can affect the sound.

Gemäß der Erfindung werden diese Mängel dadurch beseitigt, daß die Rasterungen an den gewünschten Stellen durch Abschleifen oder Polieren mittels geeigneter Schleif- oder Poliermittel .entfernt werden. Auf diese Weise hat man genau in der Hand, die Rasterungen und tatsächlich nur die Rasterungen bis zum Grund zu entfernen, ohne daß eine störende Beeinflussung der Filmschicht an dem rasterfreien Streifen oder an den übrigen Filmen erfolgen kann.According to the invention, these shortcomings are eliminated in that the Grids at the desired points by grinding or polishing using suitable Abrasive or polishing agents .be removed. That way you have exactly that Hand to remove the grids and actually only the grids down to the ground, without a disruptive influence on the film layer on the screen-free strip or on the other films.
