Description

Verfahren zur weitmöglichsten Ausschaltung der Handarbeit bei der Farbretusche an photographischen Platten Das Patent 540 525 bezieht sich auf die Ausschaltung der Handarbeit des Retuscheurs durch Anwendung photomechanischer Prozesse. Hierbei findet solches Material als Negativ oder Positivvorlage Verwendung, das geeignet ist, lichtempfindliche Stoffe zu inhibieren und bei dem die dadurch erreichte Lichtempfindlichkeit ausgenutzt wird, um unter Anwendung eines geeigneten Negativs (Diapositivs) in Konturendeckung und Lichteinwirkung eine auswählende Abätzbarkeit (Verstärkung) zu erzielen.Procedure for the greatest possible elimination of manual labor in the Color retouching on photographic plates. Patent 540,525 relates to the Elimination of the manual work of the retoucher through the use of photomechanical processes. Such material is used as a negative or positive original that is suitable to inhibit light-sensitive substances and in which the thereby achieved Photosensitivity is exploited to use a suitable negative (Slides) in contour coverage and exposure to light a selective etchability (Reinforcement) to achieve.

Die vorliegende Erfindung geht dahin, die fraglichen Negative bzw. Diapositive unter Belassung der übrigen Eigenschaften mit einer lichtempfindlichen Schicht zu überziehen, welche das Diapositiv bzw. Negativ je nach der Lichteinwirkung mehr oder weniger flüssigkeitsdurchdringlich macht. So wird z. B. ein Diapositiv oder Negativ, in welchem verkleinerungsfähige bzw. vergrößerungsfähige Rasterpunkte eingebettet sind, mit einer Chromkolloidschicht überzogen, die (wie die Bildschicht nach dem Hauptpatent) nach erfolgter Lichthärtung eine auswählende F lüssigkeitsdurchdringlichkeit besitzt.The present invention aims to provide the negatives or negatives in question. Slides leaving the other properties with a light-sensitive one Layer to cover, which the slide or negative depending on the exposure to light makes it more or less permeable to fluids. So z. B. a slide or negative, in which grid points that can be reduced or enlarged are embedded, coated with a chromium colloid layer which (like the picture layer according to the main patent) a selective liquid permeability after light curing owns.

Letztere ermöglicht es, durch Einwirkung einer Ätze, die Punkte an denjenigen Stellen besonders rasch zu verkleinern, welche vor Licht geschützt waren, während diejenigen Stellen, die belichtet wurden, sich genau so verhalten, als wenn sie mit gegen die Ätze schützendem Lack versehen waren.The latter enables the points to be attached by the action of an etch to reduce particularly quickly those areas that were protected from light, while those places that were exposed behave exactly as if they were provided with lacquer protecting against the etching.

Umgekehrt können auch lichtempfindliche Schichten verwendet werden, welche durch Einwirken des Lichtes (wie z. B. Schichten. die mit Eisenchlorid behandelt wurden) stärker flüssigkeitsdurchdringlich werden.Conversely, light-sensitive layers can also be used, which by the action of light (such as layers. those treated with ferric chloride become more permeable to fluids.

Die durch Einwirken. des Lichtes zu erzielende auswählende Durchdringlichkeit erfolgt praktisch derart, daß ein geeignetes Negativ evtl. Schablone vorgeschaltet wird, welche das Licht an denjenigen Stellen mehr oder weniger bzw, gar nicht zur Wirkung kommen läßt, die im Verhältnis zu den anderen Stellen anders ätzen sollen.By acting. selective penetration to be achieved of the light is practically carried out in such a way that a suitable negative may be preceded by a stencil which the light in those places more or less or not at all Effect can come, which should etch differently in relation to the other places.

PATENTANSPRUCH: Verfahren zur weitmöglichsten Ausschaltung der Handarbeit bei der Farbretusche an photographischen Platten, welche eine Bildschicht besitzen, in der durch Abätzung oder Anlagerung verkleinerungsfähige oder vergrößerungsfähige Rasterpunkte eingebettet sind und bei der unter Benutzung eines geeigneten Negativs (Diapositivs) unter Konturendeckung Licht zur Einwirkung gelangt, nach Patent 54.o 525, dadurch gekennzeichnet, daß die photographischen Platten mit einer Chromatkolloidschicht überschichtet werden. PATENT CLAIM: Process for the greatest possible elimination of manual work during color retouching on photographic plates which have an image layer in which halftone dots that can be reduced or enlarged by etching or accumulation are embedded and where light comes into effect using a suitable negative (slide) with contour coverage, according to patent 54.o 525, characterized in that the photographic plates are covered with a chromate colloid layer.
