Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

Fig. 1 shows a flow chart of a marking processing method for imposition according to an embodiment of the present invention, including:

Step S10, determine the layer where the mark is located in the large plate, where the layer is separated by the printed material in the large plate;

Step S20, generating a markup file for the markup of each layer.

The existing technology generally treats all the marks together as one object. The lack of hierarchical relationship in the existing technology will cause all the marks to be on the top of all printed documents. Since the upper layer of the file is not transparent, it will cover the lower layer of the file at the same position. , seriously affects the layout of the printed matter, and the accuracy of the imposition result is affected to a certain extent.

However, this embodiment proposes to process marks in layers, and the layers are related to the prints in the large plate, so when operating marks for each print, it can be associated with the marks of each layer, rather than for the entire object in the prior art processing, thereby increasing the flexibility of labeling processing.

Fig. 2 shows a schematic diagram of a large plate according to an embodiment of the present invention. The large plate contains printed matter 1 and printed matter 2, so three layers can be generated at the interval of printed matter 1 and printed matter 2, from top to bottom , followed by: layer 1, print 1, layer 2, print 2, layer 3. According to the embodiment of the present invention, a markup file can be generated for the marks of layer 1, layer 2 and layer 3 respectively.

Preferably, step S20 includes: recording in the markup file: the level of the layer corresponding to the markup file and the position of the mark in the layer. This makes it easy to associate marker files to layers.

Preferably, the marking processing method further includes: obtaining information of the printed matter in advance; Step S20 includes: determining the file type, number of pages and color surface of the marking file according to the information of the printed matter. Because the mark is associated with the printed matter, the mark file is generated according to the printed matter, which can improve the compatibility of the file.

Preferably, determining the file type, number of pages and color face of the marked file according to the information of the printed matter includes:

If the prints in the large version include both pre-separated color files and composite color files, the generation of marked files will be canceled and the user will be prompted that the file type cannot be determined;

If the prints in the large format are all composite color files, set the mark file as composite color files;

If all the prints in the large format are pre-separated color files, first set the mark file as a composite color file, which includes multiple pages, and the number of pages is the color surface of the pre-separated colors contained in all the prints Number, where the number of color faces is counted according to the name of the color face; then set the file content attribute of each page of the marked file as the corresponding color face in turn, and the content of each page is the operation related to the mark and the corresponding color face, so that the mark The file is converted to a preseparated file.

For pre-separation marks, first process and generate composite color files and then convert them into pre-separation files, which is simple and effective. Considering that there are three possibilities for the types of files contained in the printed matter, this preferred embodiment provides three setting schemes for marking files, which can be applied to various occasions.

Fig. 3 shows a flow chart of a marking processing method for imposition according to the above-mentioned preferred embodiment of the present invention, including:

Step S1: Obtain the type of the printed matter that needs to be imposed, that is, distinguish it according to the pre-separated color file or the composite color file;

Step S2: If the file type includes not only the pre-separation file but also the composite color file, then according to the principle that the pre-separation file and the composite color file cannot be impositioned at the same time, the imposition is over and the user is prompted that the next step cannot be processed;

Step S3: If they are of the same type, the layer where the mark is located at intervals between printed pieces can be determined;

Step S4: Generate a printout of all the marks located on the same layer, using a portable document format PDF file.

Fig. 4 shows a flow chart of processing a layer of marking according to a preferred embodiment of the present invention, including:

Step 301: Obtain the color plane names and CMYK description values of all printed parts;

Then judge whether all the mark files are pre-separation color files, if so then execute step S302, otherwise continue to judge whether all mark files are composite color files, if yes, then directly execute step 303, if not all are composite color files, then End the process.

Step 302: If the marked file is a pre-color-separated file, the number of color plane sets obtained in step 301 is used as the number of pages of the marked file, and each page only processes the action containing the corresponding color plane name;

Step 303: generating composite color files for all the marks located on the same layer;

Step 304: modify the file generated in step 303 as a pre-separation file, and then end the process.

Preferably, the marking processing method further includes: pre-dividing markings into custom markings referencing external files and user markings provided by the imposition system, wherein the external files contain operations decomposed by custom markings; decomposing user markings into the following operations : Line, ellipse, rectangle, text, and set font size, fill color, line color, position, width and height properties for the operation. This preferred embodiment determines the operation of the markup on the page, so that the file content of each page of the markup file can be determined. Decompose the user-defined marks into four basic operations: text, line, rectangle, and ellipse, which simplifies the processing of marks.

Preferably, the method further includes: accepting user's transformation (for example, rotation or centering) of the text mark; for the transformation, using double mirror images for positioning, and calculating the length and position of the text mark according to the font reference width and height. Calculating the length and position of a wordmark accurately describes the wordmark added by the user. It is a graphical operation interface for users to add marks, which is a simple operation (such as zooming in and out) on pictures (such as JPG format files), and these information should be accurately reflected in the generated PDF markup files . The introduction of font reference width and height can improve the calculation accuracy, for example: there are certain nuances or errors in the same font size (such as "small five" and "small four") of two different fonts (Song type, Kai type).

Preferably, the marking file is a PDF file, and the file type and color information of the printed matter are obtained from the PDF file referenced by the printed matter. PDF is the most common format in the industry, so this preferred embodiment can be applied to various occasions.

Preferably, the tag file is a self-contained file, which contains font information used by the tag, the format of the layer of the tag file is consistent with the format of the template used to generate the large version, and the reference coordinates of the format of the layer of the tag file are set from Starting from the origin (0, 0), if the format of the layer of the marked file does not adopt the origin coordinate system, it is converted to the origin coordinate system through coordinate matrix transformation. For example, a file with a size of 40*50. Its coordinates can be described as the lower left corner (0, 0) and the upper right corner (40, 50). However, it is also legal and correct to describe the lower left corner as (20, 30) and the upper right corner as (60, 80), and even directly describe information such as rotation by 90 degrees instead of directly reflecting it in the coordinates. For subsequent processing, it is necessary to convert the coordinates of the lower left corner that is not (0, 0). The converted coordinates are all standardized, and the coordinates of the lower left corner are described by (0, 0). This facilitates the application of the markup file to various output systems, and no longer depends on the output system to provide font support. In addition, the width and height of the layer of the marked file are consistent with the width and height of the imposition template, the coordinate matrix is all converted into the coordinates of the origin, and the layer of the marked file is distinguished from the printed matter to accurately identify the mark and the printed matter, and the subsequent processing and The interface display is clear and intuitive, making the user's operation easier and more accurate.

Preferably, the marking processing method further includes: sequentially storing the marking file, printed matter and additional information in the information referenced by the layout file of the large version according to the order of the layers, and determining that the marking file appears in the layout file according to the layer relationship The sequence; where, the additional information includes: whether the type of the mark is a custom mark referencing an external file or a user mark provided by the imposition system, and the color plane information of the mark file. This layout file can easily perform various processing. Adding additional information to the layout information generated by imposition can facilitate secondary analysis, which is beneficial for users to restore layout files and perform partial replacement, greatly reducing the workload and improving convenience.

Taking the manual imposition process of four pre-color-separated Portable Document Format PDF files a, b, c, d and four marks m1, m2, m3 as an example, the above-mentioned embodiment of the present invention will be further described in detail.

The order of pieces and marks is m1, a, b, m2, m3, c, m4, d. The set of color planes of the printed matter used to obtain the large version is cyan, yellow, blank, spot1, and spot2.

Second, all markers are divided into 3 layers: m1, m2 and m3, m4. Moreover, the mark file is firstly generated as 3 mark files with 5 pages of composite color files m1_001, m2_m3_001, m4_001, and the corresponding color plane actions from page 1 to page 5 are cyan, yellow, blank, spot1, spot2, that is, each The page is only executed when the action that contains the color surface corresponding to this page is executed. For example, m1 contains two basic operations: use yellow to describe a square, and use spot2 to describe a circle, then the square is executed on the second page, and the circle is executed on the fifth page.

Then, change the properties of each page of each markup file to convert it to a preseparated file. The recording sequence of the layout file surface_001 generated by imposition to the print and mark files is m1_001, a, b, m2_m3_001, c, m4_001, d.

Finally, in the layout file surface_001 generated by the imposition, record the additional information of the mark, the printed matter, the mark file and other information for subsequent processing.
