It is common for books, documents and/or the like to be created, mastered and stored as multiple single-page portable document format (“PDF”) files. Formatting a book as multiple single-page PDF files rather than as a single multi-page PDF file allows for multiple author revisions and quick and isolated updates.
Printing the entire book as a collated compilation usually requires performing a centering operation on each individual file and then printing the individual files as a single print job. A problem arises when the file images are not centered within corresponding page boxes. To address this problem, a pre-press operator is often required to add a page box, such as a trim box, to each file so that the image is centered within the page box. However, this is a tedious and time consuming process that adds significant processing time to the document production process.
Before the present methods are described, it is to be understood that this invention is not limited to the particular systems, methodologies or protocols described, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure which will be limited only by the appended claims.
It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. As used herein, the term “comprising” means “including, but not limited to.”

For purposes of the discussion below, a “document” refers to a multi-page publication. Exemplary documents may include books, workbooks and/or the like.
A “file” refers to a page description language (“PDL”) document, such as a portable file format (“PDF”) file, a post script (“PS”) document and/or any other similar file having uniform page positioning. A file may include a single page of a document.
A “page box” refers to a modifiable, rectangular region that may encompass a portion of a file. Exemplary page boxes may include a crop box, a bleed box, a media box, a trim box and/or the like.
A “crop box” defines a region to which a file's contents are to be cropped.
A “bleed box” defines a region to which a file's contents are to be trimmed when output by a production environment.
A “media box” defines the width and height of a page.
A “trim box” defines the intended dimensions of a finished page.
In an embodiment, each file may represent a single page of a document, and each page may include a digital representation of an image. In an embodiment, an image may include text, one or more pictures, one or more drawings and/or the like. In an embodiment, an image may refer to content on a page. For example, a page may include three paragraphs of text and two photographs. The image associated with that page may include the three paragraphs of text and the two photographs.
In an embodiment, a file list may include one or more file identifiers that may correspond to a name, a location, an order and/or the like associated with each file.
In an embodiment, the order of the file identifiers in the file list may represent the order of the files in the document. As such, each file identifier in the file list may correspond to a document page number based on its location in the file list. For example, referring to
In an embodiment, a first file may be selected 105. In an embodiment, the first file may be selected 105 based on the position of its corresponding file identifier in the file list. For example, the file corresponding to the first file identifier in the file list may be selected first, the file corresponding to the second file identifier in the file list may be selected second, and so on.
In an embodiment, the image corresponding to the first file may be substantially centered 110 within the first file. In an embodiment, the modified first file may correspond to the same file identifier as the original first file. The image may be centered 110 based on a page box associated with the first file. A page box may be a modifiable, rectangular region that may encompass a portion of a file. Exemplary page boxes may include a crop box, a bleed box, a media box, a trim box and/or the like.
In an embodiment, a page box associated with a first file may be set so that the image associated with the first file is substantially centered within the page box.
In an embodiment, one or more files may be selected 115. Each file may be selected 115 based on a location of its corresponding file identifier in the file list. In an embodiment, one or more files that are associated with document page numbers that share a characteristic with the document page number of the first file may be selected 115. For example, if the first file is associated with an odd document page number, one or more files associated with odd document page numbers may be selected 115.
In an embodiment, the image associated with each file that is selected may be positioned 120 within the file. In an embodiment, each image may be automatically positioned 120 based on a position of the page box associated with the first file. For example, a first file may correspond to page number ‘1’, and the image of the first file may be centered 110 in a trim box to produce a first centered image. One or more files associated with odd page numbers may be selected 115, and the images associated with each selected file may be positioned 120 based on a location of, for example, the trim box associated with the first file. In an embodiment, each modified file may correspond to the same file identifier as the original file.
In an embodiment, a second file may be selected 125. A second file may correspond to a document page number having a different characteristic than the document page number of the first file. For example, if the first file corresponds to an odd page number, the second file may correspond to an even page number.
In an embodiment, the image corresponding to the second file may be substantially centered 130 within the second file. The image may be centered 130 based on a page box associated with the second file. In an embodiment, a page box associated with the second file may be set so that the image associated with the second file is substantially centered within the page box. In an embodiment, the modified second file may correspond to the same file identifier as the original second file.
In an embodiment, one or more files may be selected 135. Each file may be selected 135 based on a location of its corresponding file identifier in the file list. In an embodiment, one or more files that are associated with document page numbers that share a characteristic with the document page number of the second file may be selected 135. For example, if the second file is associated with an even document page number, one or more files associated with even document page numbers may be selected 115.
In an embodiment, the image associated with each file that is selected based on the document page number associated with the second file may be positioned 140 with the file. In an embodiment, each image may be automatically positioned 140 based on the page box associated with the second file. For example, a second file may correspond to page number ‘2’, and the image of the second file may be centered 130 in a trim box to produce a second centered image. One or more files corresponding to even page numbers may be selected 135, and the images associated with each selected file may be positioned 140 based on a location of, for example, the trim box associated with second file. In an embodiment, each modified file may correspond to the same file identifier as the original file.
In an embodiment, the modified files may be printed 145. For example, the modified file associated with each file identifier in the file list may be printed 145 as a collated set.
