Definitions

the invention relates to a method for rapid position control a printed image on a printing form or Print template, as known for example from DE 4221482 C2 is.
the production of the printing forms or printing originals requires a high Precision.
the printed image usually becomes by means of a laser or photochemically on the printing plate applied, with these on side stops or optically positioned is to ensure correct positioning of the printed image to achieve.
the pressure plate then later for positioning on corresponding dowel pins is applied to the printing cylinder.
the Edges of a printing plate usually not worked so exactly that the desired accuracy of the mapping between Print image and punch punches is achieved.
the object of the present invention is the well-known Process to improve so that a faster situation control with a simpler camera system allows becomes.
a reference position is made by making the artwork or Pressure plate with the help of her punched or punched Punching to a corresponding number of dowel pins of Measuring arrangement applies.
the inside or outside of the Printed image located reference positions in the form of a brand or coding are in their relative position to the punch punches known, so that simple and immovable cameras or other image pickup devices only to these known Positions must be addressed.
the calculated by the computer system data are machine related and provide adjustment variables and / or deviations in each case correct unit of measurement. These are deviations the correct position of the printed image relative to the punch punches or corresponding adjustment variables, around the pressure plate when placed on the impression cylinder the printing press is automatically corrected, provided the tolerances and deviations are not a given size exceed. In this case, the pressure plate can not More can be used.
the data calculated by the computer system contain the measure like the print template with other print templates of a print set fits over each other.
This measure includes the correction quantity, to change the position of the artwork so that all the print templates of a print set fit over each other.
a pressure plate applied to dowel pins is the only one Figure shown and used to explain the below described method as an embodiment of the invention.
the pressure plate has a longitudinal edge two punched passages 5, 6, for receiving dowel pins 7, 8 serve.
a print original or Printing plate 1 serving pressure plate is usually a such plate still without punched with the outer edges Attacks or visually on a corresponding workstation positioned, then the print image 2 by laser processing or applied by chemical treatment becomes.
the two reference positions 3, 4 applied, the fixed spatial allocation stand for the print image 2.
These reference positions 3, 4 are outside the print image 2, but you can also be arranged within the print image 2, if they are sufficient are small and thus do not disturb the printed image.
Such reference positions 3, 4 often have a square Area of 0.9 x 0.9 mm.
On this surface can be a data code be applied with various information, which is an associate Ensure the pressure plates of a printing plate set. This data code can also contain information about dimensions, Orientation, format and / or color of the printing plate included. In the reference positions, however, it can be the simplest Trap only to trade position marks.
the punch punches 5, 6 are then produced, wherein their positions again with respect to the outer edges orient the plate, which is not always the required Accuracy. As a result, it may happen that the correct Assignment of punching punches 5, 6 for print image 2 respectively to the reference positions 3, 4 is not present.
the method according to the invention serves the purpose of resulting tolerances regarding the exact assignment positions or to calculate, with the determined deviations then serve the location of the printing plates on the To correct printing cylinders of a printing machine in order to achieve that all printing plates of a printing set during the printing process Create exactly superimposed images.
Deviations from the correct position result in the computer system the extent of how the respective pressure plate 1 with the rest Pressure plates of the printing set fits over each other.
the calculated Data is machine-related to the respective printing press and also include adjustment variables in each case correct unit of measurement for the printing press, so that these automatically Based on these adjustment variables may be required Position corrections of the printing plates can make. This For example, by moving or manually moving corresponding dowel pins on the pressure cylinders of Press.
the entire adjustment processes can be carried out automatically be, with the data being managed automatically and at any time for follow-up orders or correction work available stand. An operation can be omitted.
the production of printing plates can also be performed in a different order, where For example, first the punched punches 5, 6 produced and only later the print image 2 synchronously with the reference positions 3, 4 is applied.
