DE102009060399A1 - Method for placement of print element, during formation of print image on flat pre-cut part for e.g. crate, involves partially placing copy of group of print elements on surface, and removing or masking print placement marks for print image - Google Patents

Abstract

The method involves placing a print element on a surface of a sample pre-cut part, where the surface contains a print placement mark (1). A copy of a group of print elements together with the mark is partially placed on the surface and directly or indirectly placed on two surfaces in an erected condition. Position and alignment of print placement marks of the group correspond to position and alignment of print placement marks of the two surfaces. The print placement marks are removed or masked for a print image. An independent claim is also included for a computer software for performing a method for placement of print elements in correct position during formation of a print image on a flat pre-cut part for a package.

Description

The The invention relates to a method for positionally correct placement of printing elements in the design of printed images on one flat blank for packaging or the like.

packagings or the like, such as crates or boxes made of flat Blanks are erected, are usually with Provided printing elements. These may be patterns, illustrations or texts act. The printing elements must be flat on the lying blank placed in the correct position and during production be printed, so that this particular in the erected Condition of contiguous and overlapping surfaces give the desired print image.

The spatial idea of the cut for a Packaging or the like is partly complex and lying flat State not always clearly recognizable. Next to it are offshoots at the bending edges by the consideration of material thicknesses in practice in print design or reproductions often neglected.

The Construction of the blank for packaging or the like and the design and placement of the print become common made by different people or suppliers, resulting too leads to further sources of error.

So far is used in the manufacture of the packaging after the placement of Pressure elements made a trial blank and erected to Check the correct position of the printing elements to be able to. If a correction of placement required is, another sample must first be prepared and erected resulting in time delays and additional costs leads.

From the DE 101 58 083 C1 A method and system for generating proof data for packaging printing is known.

Proof data be in the reproduction technique at different stations of the Workflow for a reproduction produced. The is known Generation of proof data for an entire signature, wherein the proof data all elements to be printed such as pictures, texts, graphics, Fitting crosses, folding and cutting marks, etc. included. The proof serves In doing so, check that all elements of the sheet are correct are arranged and whether they are completely present. After the output of the proof data, the print data of the print sheet, if the proof has shown that they are in order, on color separation films or printing plates illuminated. The printing plates are in a printing press mounted, and the pressure can begin.

in the Packaging printing will be in addition to the compilation of print data and the associated proof data for a whole Sheet additionally separate proof data for generates a benefit of packaging. These separately created Proof data are used for testing in a two-dimensional or a three - dimensional representation, whether the appearance of the individual benefit of the finished packaging is in order. To this For example, the utility proof data includes a two-dimensional purpose Handling a folding box including all texts, Graphics and image content on the side surfaces of the carton (2D-proof). After printing the proof data on a color printer can the reproduction work before the start of the edition print on Accuracy, color quality, etc. are checked. If the proof data printed on a cardboard material, can The printed 2D proof also folded and become a pattern of folding carton glued together to assess the spatial effect.

Besides Proof data is also generated, which is a three-dimensional description of the packaging to be printed (3D proof). With special Computer programs can use these proof data a three-dimensional Representation of the packaging to be calculated, which is displayed on a screen becomes. In this case, the illustrated packaging by interactive Turning from all sides be considered, several similar Packaging can be placed side by side, etc., so that the advertising effect of the packaging can be assessed even better can. The 3D proof data also have the advantage of being over easily Communication links can be transferred. In this way, the coordination between the client, the Advertising agency and the printing house about necessary changes done quickly and inexpensively.

The DE 101 58 083 C1 describes a workflow in a conventional packaging packaging system. The procedure is explained for a carton to be printed on cardboard and used after folding and pasting, for example, for the packaging of biscuits. With a specially adapted computer program in a CAD system for the design of packaging, the unfolded carton is constructed, generating CAD data describing at least the outlines and fold lines of the unfolded carton. The outline lines and the fold lines also define the areas of the folding box on which an image / text content is to be printed. Adhesive edges are attached to these surfaces, with which the folding box after folding together is glued. The CAD data may be generated, for example, in the CFF (Common File Format) data format specific to the packaging industry or in the format of one of the common design programs, e.g. In the DXF format of the AutoCAD program. In a further step in a graphics system with the usual means of electronic reproduction technology, eg. Various computer programs for layout design, image processing and text editing, the image / text content created and designed to be printed on the surfaces of the carton. For example, the graphics data may be generated in the format of a page description language such as PostScript or Portable Document Format (PDF). In the next step, the graphic data and the CAD data are linked in a benefit assembly system by positioning the graphic data on the surfaces defined by the CAD data, ie the geometric assignment of the graphic data to the CAD data is determined. The resulting payload data describe a benefit of the unfolded carton in terms of the shape of the carton and the contents of the carton. In a further step, the proof data for a 2D proof (two-dimensional) or a 3D proof (three-dimensional) are derived from the payload and transmitted to a proofing system, where they are displayed or printed. Finally, in a sheet-mounting system, the print data for a signature is generated by repetitively repeating the benefits on the surface of a signature. Furthermore, in the sheet mounting system, the usual for the control of the pressure elements are mounted, such. B. passport marks a print control strip, which is composed of color fields of different colors. Today, the print data is usually generated in the format of a page description language such as PostScript or PDF (Portable Document Format). With the print data of each ink is then prepared to prepare for printing a printing plate, for. B. by exposure of the print data in a platesetter. After printing the packaging, the benefits are punched out of the printed cardboard sheets and the folding boxes are produced by folding and gluing.

To According to the state of the art, proof data are to be generated which are exact agree with the later produced packaging. For this purpose, the CAD data from the CAD system and the graphics data fed directly from the graphics system to the sheet mounting system, that generates the print data. In the sheet mounting system are the functions benefit assembly and sheet assembly combined, d. H. the graphics data be processed in the designated areas of the Packaging positioned and the benefits thus defined will be on the sheet and repeated together with the pressure control elements positioned. However, there is still the problem that the various printing elements in the design of the printed image placed in the correct position Need to become.

In contrast, the object of the present invention is a method specify with the printing elements on a flat blank in the correct position can be placed.

Solved This object is achieved by the features of the independent claims. Advantageous embodiments of the invention will become apparent from the Dependent claims.

First in the usual way, the development of a blank for packaging and printing elements for the design of the printed image of the packaging.

• a) Aufrichten eines Musterzuschnittes zu einem Modell der Verpackung oder dergleichen,
• b) Anordnen wenigstens einer Druckplatzierungsmarke als Durchbruch auf einer Fläche, welche im aufgerichteten Zustand an zumindest einer weiteren Fläche anliegt und mit dieser Fläche überlappt,
• c) Projektion der Druckplatzierungsmarke in der Tiefe auf die im aufgerichteten Zustand zumindest teilweise aneinander liegenden Flächen des Musterzuschnittes und Anordnen einer Druckplatzierungsmarke als Durchbruch auf jeder dieser Flächen, derart dass die Position und Ausrichtung der Druckplatzierungsmarken im aufgerichteten Zustand jeweils übereinstimmen,
• d) Platzieren eines Druckelements auf einer ersten Fläche des Musterzuschnittes, die eine Druckplatzierungsmarke enthält, und Gruppierung des Druckelements mit der Druckplatzierungsmarke dieser Fläche,

• f) Entfernen oder Ausblenden der Druckplatzierungsmarken für das Druckbild.

The inventive method for the correct placement of printing elements in the design of printed images on a flat blank for packaging or the like, comprises the steps:

• a) erecting a pattern blank to a model of the packaging or the like,
• b) arranging at least one pressure placing mark as a breakthrough on a surface which, in the erected state, bears against at least one further surface and overlaps with this surface,
• c) projecting the pressure plotting mark in depth onto the erected at least partially adjacent faces of the pattern blank and disposing a print plotting mark as a breakthrough on each of these faces so that the position and orientation of the print placards in the erected state coincide, respectively;
• d) placing a printing element on a first surface of the pattern blank containing a printing location mark, and grouping the printing element with the printing location mark of that area,
• e) subsequently placing a copy of the grouping of the printing element with the printing location mark of that area on all surfaces directly or indirectly adjacent to each other in the erected state, such that the position and orientation of the printing location mark of the grouping coincide with the position and orientation of the printing location mark the other surface matches,
• f) Remove or hide the print placement marks for the printed image.

In this case, the steps d) and e) can be repeated until all provided Druckele elements are placed on all surfaces of the pattern blank.

Under a pattern cut in the sense of the invention Procedure is either a real pattern of the blank for the finished packaging or a known CAD data model to understand that at least the outlines and the fold lines describes the flat lying blank and in a suitable 3D design software can be generated and processed.

The Grouping of the printing element with the print placement mark can in the case of a CAD data model by means of the corresponding software functionality respectively. The grouping can also be in the case of a real pattern by stenciling the printing location mark on the printing element.

The proposed methods using print placement marks facilitates spatial perception and simplifies the process Process for the correct placement of printing elements in the Design of printed images considerably. The invention Print placement marks are not part of the printed image. They become independent in the development of the packaging or in ignorance of the printed image attached and serve as Assistance in the subsequent design of the printed image, in which the printing elements must be placed in the correct position.

Out For this reason, it can be provided that the steps of the Packaging development and the design of the printed image and the related placement of printing elements carried out by different persons or suppliers become. The inventive method can thus be divided into a method for producing a pattern blank for the correct position placement of printing elements the design of printed images on a flat blank for a package or the like comprising steps a), b) and c) of claim 1, and in a method of designing printed images on a flat blank for packaging or the like, comprising steps d), e) and f) of claim 1.

in the Connection to the correct position of printing elements the design of printed images is from the pattern blank or from its CAD data model and the printed image with correctly placed Printing elements produced in a known manner, a printing sheet, the if necessary, comprises several blanks for the packaging, and a sample package printed and cut or punched. After release, the production of the actual packaging takes place.

The Print placement marks are placed on the corresponding surfaces the packaging arranged so that the position and orientation of the print placement marks in the erected state match. This can be beneficial using suitable 3D design software for packaging development but is also based on a real pattern of the material the cutting readily possible. For the print placement stamps These are breakthroughs that are in depth on the in the erected state at least partially contiguous Surfaces of the pattern blank are projected.

In flat presentation within 3D design software or a graphics system or the lying flat pattern the print placement marks then to transform the printing elements.

at using a 3D design software or graphics system can use the print placement marks with the printing elements grouped on a surface of the blank. A copy this grouping will then be at the corresponding print placement mark another surface of the blank by moving and rotate until the print placement mark of the grouping and the print location mark of the other area congruent are. Helpful here are the usual latching functions the graphics systems. After this transformation, the print placement marks be removed or hidden again.

It It is understood that these method steps according to also a real pattern of the blank can. The print placement marks are called breakthroughs introduced and can be used as templates for both transmission the marking on the printed image as well as the congruent positioning the transferred print placement marks on the corresponding Serve printing stamp.

After this for the transformation of the printing elements between the surfaces of the flat blank a shifting and turning required is, the pressure placing marks have a fulcrum and at least an alignment point.

According to one embodiment of the invention, the print placement marks represent a closed contour. When interpreted as a cut, this results in a breakthrough in the packaging wall. This breakthrough can be applied to the spatial model in 3D design software or on a sample cut well for congruence.

Further It is suggested that the print placement makes an inside lying vertex and at least 3 outer corner points exhibit. The inside corner serves as rotation and reference point and the outer vertices as alignment points.

The Print placement marks are not intended as printing elements for provided the ready to be printed blank. They only serve in the preliminary stage as an aid to the placement of the Pressure elements and can after the pressure arrangement again be removed. In practice, one can use the print placement marks when using 3D design software on one's own Lay layers so that they are easily hidden after use can.

A Computer software designed in such a way as to be executed on a computer a method according to the invention To carry out a simplification of the correct placement of printing elements.
