Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Schachbrett-Kontakt-Autotypierasters mit quadra tischen Rasterfeldern mit zusätzlichen Kernpunkten.The invention relates to a method for manufacturing of a checkerboard contact autotyping grid with quadra grid fields with additional key points.
Ein derartiges Verfahren ist durch die DE-PS 9 58 529 bekanntgeworden. Bei diesem Verfahren entsteht ein Kontaktraster, bei dem die Rasterelemente einen spitzen transparenten bzw. opaken Kernpunkt von vorzugs weise quadratischer, rhombischer, ovaler, kreisrunder, sternförmiger oder sonstiger Form innerhalb des Raster elementes aufweisen, und zwar derart, daß in dieses Raster mit Dichteverlauf die transparenten Punkte in die Mitte der transparenten Felder und die opaken Punkte in die Mitte der opaken Felder eingesetzt werden. Hierdurch soll der Kontrast verstärkt werden.Such a method is described in DE-PS 9 58 529 known. With this procedure a Contact grid, in which the grid elements one pointed transparent or opaque key point of preference wise square, rhombic, oval, circular, star-shaped or other shape within the grid have element, in such a way that in this Grid with density gradient the transparent points in the Center of the transparent fields and the opaque points in the middle of the opaque fields. Hereby the contrast should be increased.
Das gleiche erfolgt bei der US-PS 32 58 341, auch hier werden in die dunklen Quadrate des Schachbrettmusters, die zu den Rändern hin schrittweise das Licht mehr durchlassen, dunkle Punkte gesetzt, während in die Mitte der transpa renten Quadrate, die zum Rande hin schrittweise weniger Licht durchlassen, transparente Punkte eingesetzt werden. Die Konturenschärfe läßt sich jedoch hiermit nicht beeinflussen.The same is done in the US-PS 32 58 341, also here are in the dark squares of the checkerboard pattern that gradually let the light through towards the edges, dark spots set while in the middle of the transpa annuity squares that gradually less light towards the edge let through, transparent points are used. However, the sharpness of the contours cannot be achieved with this influence.
Durch die DE-OS 32 20 711 ist ein Satz gerasterter Druckformen für den Buntbilddruck bekanntgeworden, bei dem zwecks Maximierung der Abdeckung der Papieroberfläche in Rastertönen durch die aufzudruckenden bunten Grund farben die druckenden Rasterelemente auf jeder der zum Druckformensatz gehörenden Druckformen Ringwabenstruk tur aufweisen, wobei die Zentren der Ringwaben in 60°-Konfiguration zueinander angeordnet sind. Das Raster netz steht als Ganzes bei einer ersten Druckform des Satzes relativ zu den Bildachsen in einer Grundposition, bei weiteren Druckformen des Satzes jedoch ist das Rasternetz in andere Positionen verschoben, mit der Maßgabe, daß jeweils Knotenpunkte des Ringwabenmusters der einen mit nichtdruckenden Zentren der Ringwaben der beiden anderen Positionen übereinstimmen. Hier sind in der Mitte wabenförmiger Elemente ringartige drucken de Elemente vorgesehen. Auch mit dieser Art der Raste rung läßt sich die Konturenschärfe nicht erhöhen.By DE-OS 32 20 711 a set is rasterized Printing forms for color image printing became known at to maximize paper surface coverage in grid tones through the colorful background to be printed colors the printing raster elements on each of the Printing form set belonging to printing forms ring honeycomb structure tur, wherein the centers of the ring honeycombs in 60 ° configuration are arranged to each other. The grid net stands as a whole in a first printing form of Block relative to the image axes in a basic position, for other types of printing of the sentence, however, that is Grid network moved to other positions with the Provided that each node of the ring honeycomb pattern one with non-printing centers of the ring combs of the other two positions match. Here are Ring-like print in the middle of honeycomb elements en elements provided. Even with this type of rest The sharpness of the contours cannot be increased.
Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, auf einfache Weise eine erheblich höhere Konturenschärfe und Auf lösungsfähigkeit zu schaffen.The invention avoids the disadvantages of the prior art Technology. It is the object of the invention to be simple Way a much higher contour sharpness and on to create solvency.
Das Wesen der Erfindung besteht darin, daß an die lichtesten Stellen des unscharfen latenten Bildes bei der Herstellung des Rasters die Kernpunkte als 5% scharfe kreisförmige Flächenpunkte einexponiert werden.The essence of the invention is that to brightest parts of the blurred latent image the production of the grid the key points as 5% sharp circular surface points are exposed.
Dieses erfindungsgemäße Kontakt-Autotypieraster bringt die Schärfe des Druckpunktes wesentlich stärker zum Ausdruck. Dadurch ist die Oberfläche der wiedergegebenen Bilder vollkommener, weist eine größere Schärfe der Umrisse auf und erbringt eine bessere Zeichnung. Bei farbigen und schwarz-weißen Reproduktionen wird der Kontrast und die Güte erhöht, und zwar auch bei Druck auf einem Papier minderer Qualität. Beim Druck wird ein größeres Auftragen der Farbe ermöglicht. Dieses Kontakt-Autotypieraster eignet sich insbesondere auch vorteilhaft für die Anwendung in elektronischen Bild zerlegern. Der Druckpunkt weist einen besonders hohen Effekt auf, wenn er vergrößert wird, wie das z. B. für die Herstellung von Plakaten und dergleichen erfolgt. Die Anwendung dieses Kontakt-Autotypierasters ver bessert die Güte von Bildern in Zeitungen und Zeit schriften, die insbesondere mittels Offset-Rotations technik gedruckt werden.This contact autotyping grid according to the invention brings the sharpness of the pressure point is much stronger Expression. This makes the surface of the rendered Pictures more perfect, has a greater sharpness of Outlines and yields a better drawing. At colored and black and white reproductions Contrast and quality increased, even when printing on poor quality paper. When printing allows a larger application of the paint. This Contact autotyping grid is also particularly suitable advantageous for use in electronic image disassemble. The pressure point has a particularly high one Effect on when enlarged, such as B. for posters and the like are produced. The application of this contact autotyping grid ver improves the quality of images in newspapers and time fonts, in particular by means of offset rotations technology can be printed.
