DE449022C - Process to add additional content to the print content of printed areas - Google Patents

Description

Method of adding content to the print content of printed areas admit. The invention relates to the print content of a specific area to give some additional content. So far, a Newspaper, book, etc. only achieved a single specific reproduction. Was the The space available for printing was generally no more Content to add more. Only overprints, i.e. a second, third, etc. in of a different color or in any case in such a way that the first print is not essential Disturbance for the person taking in the contents was possible.

The present invention allows for a single press over the full printing of the space available for printing with a allow certain print content to appear at the same time as additional content, without the legibility or recognizability of the first print content is essential is affected.

The method is to leave any suitably Make changes to the printing area, which will appear on the prints appear as highlights compared to the normal print and are easy to recognize the desired further content is sufficient, but otherwise the legibility or recognizability of the main print content on the prints. Under "Printing" means the general process, i.e. newspaper printing, letterpress, Copper printing, steel printing, stone printing, offset printing. Stuff printing etc.

Ou tio n: It would be easiest to use letter printing of the same size, but on the one hand thick and on the other hand thin letters, etc. when setting. But there is a correct placement of certain contrasting parts should be practically feasible within the set of letters, especially since such Contrasting texts, etc., are expediently mostly in any or any direction, So do not pull over the main pressure according to the setting lines, so recommend For example, the following explanations can be found by machining the printing plate (Die cast) surface by means of a finely ribbed steel sheet of the desired Shape and by means of a wooden hammer (i.e. by mechanical means) can be very easily rounded quickly make the changes to achieve contrasts on the prints by making the part of the pressure plate surface corresponding to the shape thereby ribbed will; the prints removed from this printing plate then show the main content in ordinary and ripped print together, the further (pseudo) content through the figures, letters, etc. appearing in ripped print Further can be achieved by sufficient action (moistening or spraying) by acids, Bases etc. (i.e. by chemical means) on part of the printing plate surface (e.g. through appropriate vignettes) change this part compared to normal pressure, which also creates the desired contrast on the printing plate and thus on the print brings forth.

Also with physical means, e.g. B. by means of a glowing fine Wire mesh that is placed on the relevant part of the printing plate surface or on him is brought close, a change and thus the desired contrast can be achieved.

In addition, new print contents can be better known in the preparation process Way also by raising or lowering parts of the printing plate surface, des Set or the printed surface (of the paper, etc.). So can z. B. by underlaying the printing plate with pieces of paper or sheet metal of the desired Form small elevations of the underlying parts, which look thin make the prints recognizable by making the pressure more prominent. Or it can be the area to be printed (paper, etc.) on the back during printing by Papierustv. Pieces of the desired shape are underlaid, which also the contrasts on the prints can be achieved.

Of course, such changes can also be made by several means reached together and also easily already on the die, etc. or even on the Typesetting can be made. So you will z. B. part of the die (approx using stencils) can be powdered with any fine dust; when casting is this dust is a difference from that cast from the powdered parts of the die cause the pressure plate surface cast from non-powdered parts that has a corresponding effect on the printout.

Claims (1)

PATENT CLAIM: A method of giving additional content to the print content of printed areas, characterized in that the messages, figures, etc. are emphasized by a single, simultaneous printing process on the printed areas, together with the overall printing, in that any Type of pressure surfaces, matrices, counter pressure surfaces or the like, the necessary local changes are made by mechanical, chemical or physical means.
