Description
Verfahren zur Herstellung von Farbrasteraufsichtsbildern auf durch Feuchtigkeit Die Erfindung bezieht sich auf diejenige Form der Farbrasterphotographie, bei welcher eine auf einem undurchsichtigen Stoff, wie z. B. Papier, der durch Schwankungen .in seinem Feuchtigkeitsgehalt der Ausdehnung und Zusammenziehung unterworfen ist, hergestellte Rasterphotographie mit einem dem Aufnahmeraster kongruenten Farbraster verbunden wird. Es liegt auf der Hand, daß dabei die Rastrierung des Aufsichtsrasters registerhaltig mit dem" Raster der Kopie züsammengepreßt sein muß.Process for the production of color halftone images on by Moisture The invention relates to that form of color raster photography, in which one on an opaque material, such as. B. Paper that is subject to fluctuations .is subject to expansion and contraction in terms of its moisture content, produced raster photograph with a color raster congruent to the recording raster is connected. It is obvious that the rasterization of the supervisory grid must be pressed together in register with the "grid of the copy.
Bei der verschiedenen Dehnung des Papierbildes ist eine genaue Registerhaltung nur schwer zu erreichen, denn der Fehler kann unmöglich vorher in Anschlag gebracht werden, etwa indem man die im Papier vorhandene Feuchtigkeit schätzt oder feststellt und falls sich nach irgendwelcher Behandlung dieses Verhältnis geändert haben sollte, dasselbe genau so wiederherstellt, ehe man den Farbenaufsichtsraster und die Rasterbildkopie dauernd vereinigt.With the various stretches of the paper image, precise registration is essential Difficult to reach, because the error cannot possibly be brought into account beforehand by estimating or determining the moisture present in the paper and if, after any treatment, this relationship should have changed, the same is exactly restored before the color supervision grid and the raster image copy permanently united.
Vorliegende Erfindung überwindet diese Schwierigkeiten dadurch, däß sie die Dimensionen des Papiers unveränderlich erhält von dem Augenblick an, wo die gerasterte Kopie darauf hervorgebracht wird, bis dasselbe. dauernd mit dem Farbenaufsichtsraster vereinigt wird. Zu diesem Zweck wird das z. B. mit Halogensilber-Gelatine-Emulsion überzogene Papier, auf dem das Rasterbild kopiert werden soll, mit Wasser vollständig gesättigt, bis es die praktisch maximale Ausdehnung erhalten hat. Hierauf wird das Papier in diesem gedehnten Zustand mit dem zu kopierenden Rasternegativ zusammengebracht, belichtet und unter Vermeidung- des Trocknens entwikkelt, fixiert und gewaschen. Dann wird es, noch völlig gedehnt, mit einem Farbenaufsichtsraster zusammengebracht, der dem ursprünglich bei der Herstellung des Rasternegativs gebrauchten. Aufnahmeraster entspricht, sorgfältig mit diesem zusammengepaßt, was im vollen Tageslicht leicht geschehen kann, und in nassem Zustande dauernd damit vereinigt.The present invention overcomes these difficulties in that it invariably receives the dimensions of the paper from the moment it occurs the rasterized copy is brought out on it until the same. constantly with the color supervision grid is united. For this purpose the z. B. with halosilver gelatin emulsion coated paper on which the raster image is to be copied with water completely saturated until it has attained practically maximum expansion. Then that will Paper brought together in this stretched state with the raster negative to be copied, exposed and developed, fixed and washed while avoiding drying. Then, still fully stretched, it is brought together with a color control grid, the one originally used in the production of the halftone negative. Recording grid matched, carefully paired with this, what easily in full daylight can happen, and when wet it is permanently associated with it.
Dies kann in der Weise geschehen, daß man die auf dem nassen Gelatine-Emulsionspapier erzeugte Rasterbildkopie mit dem Farbenaufsichtsraster in innige Berührung bringt und so die gegenseitige Lage zwischen demselben und dem die Rasterbildkopie tragenden Papiere unverrückbar macht. Bei Verwendung anderer als Gelatine-Emulsionspapier ist es nötig, einen Klebstoff anzuwenden, um die beiden Elemente dauernd miteinander zu verbinden.This can be done in such a way that you put them on the wet gelatin emulsion paper brings generated raster image copy with the color supervision grid in intimate contact and so the mutual position between the same and the one bearing the raster image copy Makes papers immovable. When using anything other than gelatin emulsion paper it is necessary to apply an adhesive to keep the two elements together permanently connect to.
Es ist klar, daß bei Exponierung von trekkenem Papier hinter dem fertigen Rasternegativ dieses Papier durch nachträgliches Anfeuchten beim Entwicklungs- und Fixierprozeß so seine Form verändert, daß das Bild ganz außer Register, ommen würde.It is clear that if exposed paper is behind the finished Raster negative this paper by subsequent moistening during The process of development and fixation changes its form in such a way that the image is entirely out of place Register, would ommen.
Bei ddi* -Aüsfübug" Vifes Verfahrens wird der Fx-lactfsrchsrtrdeks bequemerer Handhabung vorübergehend auf eine Unterlage, z. B. aus Glas, gebracht, von der er zusammen mit der Rasterbildkopie, wenn das Ganze getrocknet ist, zuletzt abgezogen werden kann: Es ist bekannt, daß bei dieser Art Farbrasterphotographie der Farbenaufsichtsraster nur schwache Farben enthalten darf. Um den Glanz der Farben zu erhöhen, versieht man zweckmäßig das Papier, bevor es den lichtempfindlichen Überzug erhält, mit einem glänzenden metallischen Überzug vorteilhaft von Silber in feinverteilter Form in solcher Weise,, daß das Papier sich ausdehnen kann, ohne daß es dadurch selbst oder daß der metallische Überzug dadurch Schaden leidet.With ddi * -Aüsfübug "Vifes procedure the Fx-lactfsrchsrtrdeks more convenient handling temporarily on a pad, e.g. B. made of glass, brought, of which he, together with the raster image copy, when the whole thing is dry, last can be deducted: It is known that in this type of color halftone photography the color oversight grid may only contain weak colors. About the shine of the colors To increase it, it is advisable to apply the paper before it is sensitive to light Plating is given, with a shiny metallic coating, advantageously of silver in finely divided form in such a way, that the paper can expand without that it itself or that the metallic coating thereby suffers damage.
