Description

Verfahren zur Herstellung von scharfrandigen Siebdruckschablonen Es ist bekannt, durch Übertragung von Gelatinebildern auf Seidengaze Siebdruckschablonen herzustellen, und zwar werden zu diesem Zwecke Chromatgelatinebilder auf Papier nach dem Auswaschen auf Seidengaze übertragen. Dieses Verfahren ist sehr umständlich, da eine mehrfache Übertragung stattfinden muß und da durch die hvgroskopische Eigenschaft des Abziehpapiers und auch durch das Abziehen selbst Teile der Gelatinebilder sich verziehen und beim nachherigen Druck nicht mehr passen.Process for the production of sharp-edged screen printing stencils Es is known by transferring gelatine images onto silk gauze screen printing stencils for this purpose, chromate gelatine images are made on paper after washing, transferred to silk gauze. This procedure is very cumbersome, because a multiple transmission must take place and because of the hvgroscopic property of the release paper and also by peeling off parts of the gelatin images themselves warped and no longer fit when you press it afterwards.

Nach dem bisherigen Verfahren des direkten Lichtpausens auf mit Chromatgelatine lichtempfindlich gemachter Seiden- oder Metallgaze hat sich der Übelstand herausgestellt, daß die Gelatine beim Antrocknen keine scharfen Ränder in der Zeichnung läßt, da die Gelatine sich beim Trocknen zusammenzieht und entsprechend den Gewebemaschen zickzackförmige Ränder gibt.Using the previous method of direct blueprint on with chromate gelatine silk or metal gauze made sensitive to light, the problem has turned out to be that the gelatine leaves no sharp edges in the drawing when it dries, because the gelatin contracts as it dries and corresponds to the mesh of the fabric there are zigzag edges.

Es wurde gefunden, daß ein lösbares, nicht hygroskopisches Material, wie beispielsweise Celluloid, als Rückschicht des Chromatgelatinefilms die Ränder des ausgewaschenen Gelatinebildes so lange festhält, bis die Gelatine an dem Maschengewebe angetrocknet ist. Da keine mechanische Beeinflussung durch Abziehen oder Übertragen stattfindet, bleibt das Bild in unveränderter Form auf der Maschengaze haften. Zweckmäßig wird die Gaze vorher mit einer wäßrigen Gelatine-Lösung behandelt, damit das Gelatinebild besser haftet.It has been found that a releasable, non-hygroscopic material, such as celluloid, as the backing layer of the chromate gelatin film, the edges of the washed-out gelatine image until the gelatine sticks to the mesh has dried on. As there is no mechanical influence from pulling or transferring takes place, the image remains unchanged on the gauze. Appropriate the gauze is treated beforehand with an aqueous gelatin solution so that the gelatin image sticks better.

Gleicherweise kann der Celluloidfilm direkt mit der Gaze vereinigt werden und der Gelatinefilm zusammen mit der Gaze belichtet werden. In beiden Fällen wird von der Gelatineseite durch ein Lösungsmittel die Celluloidschicht stellenweise gelöst und durch Abtupfen der gelösten Stellen das so behandelte Maschengewebe teilweise durchlässig gemacht. Die belichteten Stellen werden durch das in. dem Maschengewebe bzw. auf der Gelatineschicht verbleibende Celluloid verstärkt. Die Chromatgelatineschicht kann nach bekannten Verfahren oder nach Patent 528 209, Verfahren zur Herstellung von Halbtönen auf Siebdruckschablonen, auf einen dünnen Celluloidfilm gebracht werden.Likewise, the celluloid film can be directly incorporated with the gauze and the gelatin film together with the gauze are exposed. In both cases the celluloid layer is partially removed from the gelatin side by means of a solvent loosened and by dabbing the loosened areas partially the mesh fabric treated in this way made permeable. The exposed areas are through the in. The mesh fabric or celluloid remaining on the gelatin layer is reinforced. The chromate gelatin layer can be made according to known methods or according to patent 528 209, method of manufacture of halftones on screen printing stencils, on a thin celluloid film.

PATENTANSPRUCH: Verfahren zur Herstellung von. scharfrandigen Siebdruckschablonen, dadurch gekennzeichnet, daß ein Chromatgelatinefilm, der als Rückseite eine dünne Celluloid- oder Lackschicht besitzt, mit Seiden-oder Metallgaze verklebt wird und daß nach dem Entwickeln die Cellu'.oid- oder Lackrückschicht von der Gelatineseite aus durch ein geeignetes Lösungsmittel stellenweise herausgelöst wird, so daß das ungelöste Gelatinebild mit einer Celluloid-oder Lackrückschicht in der Gaze verbleibt.PATENT CLAIM: Process for the production of. sharp-edged screen printing stencils, characterized in that a chromate gelatin film, the back of which is a thin Celluloid or lacquer layer, is glued with silk or metal gauze and that after developing the cellu'.oid or lacquer backing from the gelatin side is dissolved out in places by a suitable solvent, so that the undissolved gelatine image with a celluloid or lacquer backing layer remains in the gauze.
